ZTE Nubia Z17 review Driven by ambition

Introduction

Getting a new Nubia device is always a different experience for us. Its never been an overwhelmingly delightful or agonizingly poor first encounter, but always a pretty daunting one to wrap your head around. Bold and distinct design, high-end hardware at a bargain price, original screen gestures - these have always been a prominent part of the package ever since the Nubia Z9.

Nubia Z17 review

The new Z17 keeps throwing curve balls, making it even harder to define what this phone is all about, put a finger on a single signature aspect or feature. The latest Nubia flagship comes with a trendy dual-camera setup and the beastly Snapdragon 835 chipset under the hood. The Z17 boasts Qiuck Charge 4+ support before everybody else and ZTE still managed somehow to hang an extremely competitive price tag on it. At about $465, the Nubia Z17 undercuts the OnePlus 5 and the Xiaomi M i 6 by a few dollars, pointing to a less-than-subtle stab at the "cheapest Snapdragon 835 phone" title.

There is clearly a lot of ground to cover and different aspects of the Nubia Z17 to explore. But before we dive head first into that, there is one point of discussion that always seems to emerge when we review a Nubia handset - the ZTE connection. Nubia started as (and still is) a ZTE subsidiary but its a stand-alo ne brand that has always played by slightly different rules. Not unlike Huawei and their Honor brand. Speaking of, ZTE and Huawei are domestic and global rivals in not only consumer devices but telecom and network equipment.

In a broader sense, Nubia is related to ZTE in much the same way OnePlus is to Oppo. Both offshoots seem to have more freedom to experiment and be different, while still enjoying the strong corporate backing and RnD and manufacturing resources. With ZTE fighting its own battles with the likes of the Axon and Blade lineups, Nubia is challenging the big names in the premium tier.

That being said, the big question is whether the Nubia Z17 can, for starters, stand up to the value flagships by OnePlus and Xiaomi. Another potentially interesting relationship to explore is the one between the Nubia Z17 and ZTE Axon 7/7s. Well try and find out which approach worked out better.

Follow along on the next page for a closer look at the exterior design of the Nubia Z17.

Unboxing

A Nubia handset will never miss an opportunity to make a fancy entrance. Just like the Z11 and the Z9 before it, the Z17 a rrives in style. The packaging is somewhat simpler, but thats probably a good thing since nobody really needs an expensive box pushing the price up.

The companys traditionally bold black and red accents are still intact, though. The phone comes in a two piece cardboard box. The contents are set on two levels, the accessories packaged underneath the handset itself. Both the Nubia Z9 and Z11 came with a premium set of headphones in the box. Our Z17 review unit had none. It might be a market-specific thing or the headset fell victim to cost-cutting this time around. Either way, a quality set couldve probably helped users get over the missing audio jack.

Thats right, Nubia made the switch to a single Type-C port, getting rid of the 3.5mm audio jack. Of course, this means you need to embrace #donglelife and carry around the little passive adapter. Also, you cant really charge your phone while listening to music, not without an extra adapter, that is.

Sourcing the latter might be a challenge, especially if you want to keep using the DAC inside the Z17 and not one embedded in a dongle or the headphones themselves. Nubia opted for the Type-C standard, but left a DAC inside the phone that carries its analog audio via the pair of Sideband Unit (SBU) pins on the Type-C port.

What that means is that the provided dongle doesnt do any conversion, but simply connects your audio jack to the said pins. There are certain benefits to this approach, one of which being that you dont have to rely on external DACs in third-party accessories. That, however, is only valid if the internal DAC performs well - well test that in detail in the audio chapter. Of course, you can still pick up any pair of active Type-C headphones or an active adapter to use with the Nubia Z17.

On to charging then. As mentioned earlier, Nubia boasts Quick Charge 4+ compatibility on the Z17, an industry first. In all fairness, the QC 4/4+ situation is currently a bit murky, but the promo materials did mention up to 15% faster charging on mobile devices and we are pretty certain that must require up to 28W of power output. However, the charger provided with the Nubia Z17 is only rated at 12V@1.5A, 9V@2A and 5V@3A. This is exactly what the older QC 3 is rated at. Plus, the Z11 charger was clearly labelled QC3, while the Z17s unit has absolutely no mention of Qualcomm or its charging tech.

As we researched this even further, it turned out that at the time of writing this, there is not even a formal procedure in place for certifying Qualcomm QC4+ chargers. Were sure these will come to the market, but just not yet.

Nubia Z17 reviewNubia Z17 charging time

So even if the Nubia Z17 is compatible with the new standard, the bundled charger isnt. Now, that might be an issue of supply and availability that will be remedied in units shipped at a later point. But, with the package we got for testing, it is really not fair to claim Quick Charge 4 or 4+ technology. The charging times we got in our battery tests prove our point.

Nubia Z17 360-digree spin

If there is one thing we can definitively say about Nubias flagship line these last few years is that ever since the Z9, every device has had a unique appearance. The signature red contrasting accents got carried over to the Z11 and now to the new Z17 as well. Its an acquired taste for sure, but we still admire Nubia for sticking with those little yet prominent accents.

As for the construction, there is an obvious consistency to be observed as well - you get the curved front glass, complete with Nubias clever optical tricks to simulate an edge-to-edge panel. There is also the exquisite brushed metal frame.

Beyond that, the Z17 is an interesting mix of its two predecessors. It features the metal back of the Z11, as well as a rounded frame. However, the chamfers look a lot similar to those on the Z9, with strong and well defined edges.

Nubia Z17 reviewNubia Z17 color options

In fact, the Z17 seems to be trying to rekindle the really bold look of the Z9. Some of the color options take the red theme to the extreme. Flame Red is a particularly strong spin on the traditional Nubia black and red scheme, only reversed. Then there is Aurora Blue, which reminds us of the equally eye-catching similar shade on the recent Huawei P10.

It is worth noting, however, that neither the soft finish on the back, nor the side cham fers really provide a secure grip. The Z17 is a very slippery handset. The curvy front panel doesnt help in this respect either.

Hardware overview

An edge-to-edge display is always an attention-grabber. The same goes for a curvy front panel. By those standards, the Z17 looks very trendy but, to be fair, it cant really be part of the curved display elite. Unlike Samsung or Vivo, Nubia still hasnt gone the extra mile to actually curve a panel. Instead, the Chinese OEM has a simpler and far less expensive approach. Just like the Z11 and Z9 before it, the Z17 uses some clever optics to sort of stretch out the edges of the picture onto the curved part of the glass. It is a cool solution but certainly has its drawbacks, like image distortion along the edges.

Material-wise, you get an undisclosed v ariety of Corning Gorilla Glass on the front. Also, to further ease the minds of potential buyers, Nubia claims its aRC 2.0 design not only looks good but also provides some additional shatter protection, thanks to a cushion layer between the screen glass and the metal frame. Then again, this isnt something new - the Z11 was built the same way.

Aside from the glowing red circle on the home button, the front of the device is surprisingly clean. Even though the color is admittedly a bit out-there, we got used to in pretty quickly and we have to say it looks particularly good in the dark. If its up your alley, you can also enable the breathing light function.

There are two more capacitive controls beneath the display as well. These are only marked by small red backlit dots and can be remapped to Menu and Back the way you like - neat!

At the top you get the 16MP selfie camera, an earpiece and proximity and light sensors. The latter two are pretty well concealed on models with a black frame.

Around the rear, the Z17 offers an almost uninterrupted and surprisingly smooth metal surface. Gone are the plastic top and bottom bits from the Nubia Z11. Instead, Nubia has managed to get away with only one and well concealed antenna line near the bottom of the back panel. The fingerprint reader almost looks like a naturally recessed point in the metal plate, while still retaining a distinct chamfered edge for finger guidance.

The dual-camera setup is compact and fits snug in the top left corner, along with its dual-tone LED flash. It features a very slight camera hump, which shouldnt really be a problem, as far as lens protection goes, especially if you opt for a case. The red accent really ties in well with the button LEDs on the front, but we just cant shake the feeling that something is wrong - either the red line or the entire camera module are somehow misaligned relative to the phones body.

The sides of the unit are both very clean. You only get a SIM card tray on the left that can take one or two SIMs. Sadly, no microSD expansion option. It sits very flush and has the exact same color as the frame i tself.

The same goes for the volume rockers and power button on the right. There are no accents or textures here, which we appreciate overall, but also seems like a missed opportunity for some extra signature accents.

The bottom of the Nubia Z17 has the USB Type-C port, flanked by two symmetrical grilles. Only one is an actual speaker though. The other one houses the main microphone.

There is a second mic on the top of the unit for noise suppression, along with an IR blaster - an increasingly rare feature. What is missing, though, is a 3.5mm audio jack. You just have to live with either analog or digital audio via USB.

One very interesting thing to note here is the fact that an almost invisible plastic inlay runs down the middle on the top bezel and extends slightly down the sides on the phone. This is actually and extremely well concealed second antenna line. We are really impressed with Nubias approach here.

Display

"Bezel-less" is not exactly the buzzword it was a few years back. Infinity displays and ultra-wide aspect ratios seem to have taken over. Still, Nubia s optical tricks are impressive enough, even if a little outdated. As already mentioned, however, there is a downside to bending light to extend out an otherwise flat LCD panel. You can spot distortions along the edges quite easily, especially when viewing the phone at an angle.

Still, if you dont focus too much on the image quality in that particular border area, the overall style benefits still outweigh the inherent deficiencies. In other words, we quite like what we see. Just like its predecessor, the Z17 uses a 5.5-inch, FullHD panel. Nothing too fancy, but still plenty sharp, with a pixel density or around 403ppi.

Nubia Z17 review

The panel is a rather basic IPS LCD unit, but one with surprisingly wide viewing angles.

The maximum brightness is average and tops off at around 388 nits. There is a Max Auto boost that needs to be enabled in the settings first. However, it is not particularly useful, as it only managed to push the display up to 392nits in our tests.

Still, thanks to the low black luminance, the Nubia Z17 scores a respectable contrast level. Sunlight legibility is serviceable, although not really impressive.

Color accuracy is not really the Z17s strong suit. This is rather surprising since it offers quite a few color correction options. On the default "Colorful" setting, we measured an average deltaE of 6.5 and a maximum of 13.1. Lowering the brightness down to 200 nits only made things worse. Overall, the panel just looks really cold, with a clear blue tint to whites. Individually, most of the other colors arent all that bad.

For the most c olor-accurate settings possible, we ended up using the "Natural" color mode and sliding the gamma correction as far as it goes into the Warm setting (makes sense). This resulted in an average deltaE of 5.1 and a maximum of 11.1 - still far from what we would consider color-accurate. Of course, for many users out there, this may not be a strong point of consideration.

Connectivity

The Nubia Z17 ticks most boxes when it comes to connectivity. It is a Dual-SIM device taking two nano SIMs. Worldwide band coverage across 2G, 3G and 4G is pretty decent - definitely better than the Xiaomi Mi 6, although nowhere near the OnePlus 5. The LTE is Cat. 12/13 for theoretical speeds of up to 600Mbps of download and 150Mbps of upload - theres no gigabit LTE on the Nubia Z17, even though the chipset is heavily advertised to support it. We dont really think its that much of an issue.

Wi-Fi b/g/n over 2.4GHz and a/n/ac over 5GHz is supported. Bluetooth is still of the older 4.1 var iety, so dont expect anything fancy along the lines of the OnePlus 5s aptX HD. NFC support is another check mark on the spec sheet. Positioning uses GPS, GLONASS and BeiDou satellites. There is no FM radio, but the Nubia Z17 does have an IR blaster.

The only interface you get is USB Type-C. We already mentioned it supports analog audio output, via the provided adapter. It also has OTG.

Battery

The Nubia Z17 is equipped with a 3,200mAh battery - only a bit smaller than that of its OnePlus rival and nearly identical in capacity to the Sony Xperia XZ Premiums unit. Since all of these smartphones are based on the Snapdragon 835 chipset, there is a certain degree of consistency to be expected in terms of battery life.

Nubia Z17

For the most part, this appears to be true. The Z17 managed to score an impressive 81 hours of endurance in our testing routine. A quick comparison with the OnePlus 5 reveals that both devices behave equally well in terms of 3G call time. 19h is definitely not bad, especially considering poor past experiences weve had with units intended for the Chinese market and networks.

Video playback is quite easy on the battery as well. 12:26 is a definitely a solid accomplishment on an LCD panel. Naturally, the OnePlus 5 squeezed a few hours more out of its efficient Optic AMOLED display. But its the browser that pleasantly surprised us. Since our Z17 unit didnt have Google Play Services or Chrome pre-installed, we opted to conduct the test with the default browser. Initially, we were quite suspicious of it, as it seemed to be prone to some off traffic re-routing and the default ad blocker managed to kill the JavaScript on our test suite. Still, once we turned the latter off, the browser did very, very well, netting over 13hours of endurance.


Our endurance rating denotes how long a single battery charge will last you if you use the Nubia Z17 for an hour each of telephony, web browsing, and video playback daily. Weve established this usage pattern so our battery results are comparable across devices in the most common day-to-day tasks. The battery testing procedure is described in detail in case youre interested in the nitty-gritties. You can also check out our complete battery test table, where you can see how all of the smartphones weve tested will compare under your own typical use.

Nubia UI 5.0 - feature heavy

Like many other manufacturers, primarily aimed at the Chinese market, Nubia is no stranger to flashy, bloated and over the top custom versions of Android. Nubia UI 5 is no exception to the rule. The OS is custom end-to-end and is filled to the brim with added features and little tweaks and options everywhere you look.

Nubia Z17 review

Our review unit is particularly stuffed with "stuff" since it is running a Chinese ROM Android 7.1.1 Nougat ROM. Besides the multitude of odd local apps, this also means a total absence of Google Play services and the Google App package and no apparent way to sideload any of them. Not without rooting the device, at least. Of course, we did our best to work around this and not to judge the OS too harshly based on its localized features. What we did find a little hard to swallow, however, was the overwhelming amount of bad and confusing English text translations, found all throughout the UI.

Bad English translations and Chinese text are a common occurrence - Nubia Z17 reviewBad English translations and Chinese text are a common occurrence - Nubia Z17 review
Bad English translations and Chinese text are a common occurrence

A few quick online searches, however, did lead us to stores, claiming to offer the Nubia Z17 with an international ROM, which hopefully has no such issues and is a lot more streamlined. Not to mention, the presence of Google Play Services. You should look for such a unit if you decide on importing the Z17 from China.

Last year, we praised the Z11 unit we got for review for the clean and almost vanilla feel of its International Android 6 - Nubia UI 4.0 ROM. This time around, however, we find this version of Nubia UI 5 adopting the polar opposite ideology of "more is better." We realize added functionality can be a major draw for many prospective buyers, but there still has to be a cutoff point somewhere. And Nubia UI 5 plays fast and loose with this abstract boundary.

Before we go on criticizing the bloated nature of the OS, we feel it is worth giving credit to N ubia for including a powerful Themes engine this time around. This was a sore point we had with the older version of the ROM. Again, it might be a regional thing, since the Z9 also had a Theme store. All we know is our review unit has a rich online selection of skins, along with a choice between a 4 or 5 column interface.

To truly make the Z17 yours, you can also rearrange the capacitive home buttons. By default, the back key is on the right, old-school style. You can even bind a long press on the home button to one of a few pre-defined system actions. Not the other two buttons, though.

The lockscreen also lends itself to some visual tweaking. By default, you only get a simple static image, with a clock widget, and a quick camera shortcut. However, there are also a few other unlock options to choose from and a dynamic GalleryLockScreen setting. It comes complete with its own online repository of images, divided into categories you can subscribe to. Of course, you can add your own photos to the mix as well.

Nubia has opted out of an app drawer once again. Thats the launcher style popular in China, no app drawer - instead, you are supposed to have all apps on the homescreen (think iOS, but with widgets here and there).

Folders help organize the madness if you have too many apps and you can dock the 4 or 5 most used apps in the bottom row. Some of the folders also come with an optional app suggestion feature that tries to bring up relevant apps, based on your usage history.

By default, the leftm ost panel on the home screen is dedicated for shortcuts to Nubias numerous special camera modes. It also houses the neoShare activity widget, which is another local Chinese-only feature. Luckily, the launcher does give you an option to disable this page altogether.

One area that has received a major redesign in Nubia UI 5 is the notification and quick toggle shade, or should we say shades. This time around, Nubia decided to separate the two things out in a vaguely iOS fashion. Swiping from the top of the interface opens a dedicated notification are - one of s everal the OS recognizes as distinct places for notifications.

The quick toggles and brightness slider are moved to their own shade, that, unfortunately, doesnt seem to offer customization. It can be pulled up from the bottom of the UI.

Just be sure to swipe up a little to the left or right of the home button. Doing a central swipe is a different gesture, which by default, triggers the Split screen UI. The gesture situation gets even more confusing if you opt to trigger the slip screen feature with a downward swipe as well. Oh, and there is also a side panel to the right. It acts as somewhat of a Google Now interface, with a few available widgets. These can show you reminders, a quick summary of the system status, recent files or quick contextual travel directions.

Boy, thats a confusing mess of gestures and interfaces, if we ever saw one. And its just the tip of the iceberg. Just wait until we get to the rest of the edge and touch gestures the Z17 has to offer in a little bit.

The Split Screen feature is actually one of the better implementations out there, minus a few slightly irritating issues. For one, you can view the homescreen twice, dock and all, which just looks weird. Also, not all apps resize to fit their allotted portion of the screen, most remain a downscaled 16:9 version of themselves, which is often too tiny to use properly. The good news is that even third-party apps seem to work in this mode and some of them are smarter about resizing than the Nubias native apps.

Speaking of powerful multitasking, we cant fail to mention another great little trick the Nubia Z17 can pul l off. It is called Dual instance and just like the name suggests, it allows you to have two separate versions of an app installed.

But before we get into all the extra usability features, and there is a lot of them to cover, lets finish off with the basic navigation and notifications. The app switcher employs a horizontal layout, with a swipe away gesture for recent apps. Theres also an X that will "Accelerate" your phone by closing running apps and freeing some ram.

You actually get a say in what background activities get axed by this optimizer. This is achieved on a per-app basis within the Power settings menu. Unless you specifically tell the OS not to touch a certain app, it will get the boot. It is perhaps worth noting that Nubia has made the feature more aggressive, since the logic used to be the other way around in Nubia UI 4.

And if you think thats the only battery saving measure Nubia UI 5 has to offer, you are wrong. Besides the per-app control, you also get four distinct power savings schemes. And thats not even counting the three power savings modes, including a super saver one, which limits the phone to basic functionality only. You can get some pretty detailed battery usage statistics for both hardware and apps as well.

You also get to decide exactly which apps can autostart with the system , potentially saving even more power. That is actually part of a bigger interface for managing permissions on a per-app level. As you can imagine, this includes controlling their access to hardware components, like the camera or GPS as well. Handy, for sure, if you have the time to get your hands dirty and manage every single app, without potentially crippling or breaking it.

And there is more potential still for granular control and hardware optimization, all bundled up in the NeoSafe app. You can access most of the features we just described from various points in the set tings menu as well, but NeoSafe is the convenient central managing hub for them all. We already discussed the Permissions and Power options and the Cleaner and Antivirus are pretty self-explanatory.

Flow is an extension of the permission manager, which lets you restrict certain apps from using Wi-Fi or network data. We assume it is somehow tied in with Nubias own roaming data package market, which is one of the numerous apps, pre-installed on the Z17. Intercept lets you whitelist or block numbers for calls and notifications - pretty nifty.

Speaking of notifications, we mentioned Nubia UI 5 recognizes a few distinct types of them and areas to display them in. It also offers a phenomenal level of per-app granular control. Bear in mind that most apps tend to install without granted access to any notification privileges by default. So, if you need something in particular, you have to go in and enable it specifically rather than the other way round.

Gestures

While Nubi as approach to a curvy front panel might not be the most cutting-edge or technologically advanced one, the OEM has managed to make great use of its bezel-less design with a plethora of custom gestures.

First up on the list of gestures is the inward swipe that brings up the FIT Card interface, we mentioned earlier. Swipe up or down on one side of the screen - that can switch back and forth between apps or launch a couple of apps (one for up, one for down). Oddly, the left and right edges can no longer be individually set to either mode, which was a thing on the Z9.

Edge gestures - Nubia Z17 reviewEdge gestures - Nubia Z17 reviewEdge gestures - Nubia Z17 review
Edge gestures

The Z9 used to recognize squeeze, much like HTCs U U11, but the featur e was removed from the Z11 and it is absent from the Z17 as well. Frankly, its not really that big of a loss, since the control scheme is already incredibly confusing even with one less available gesture.

Even more Edge gestures - Nubia Z17 reviewEven more Edge gestures - Nubia Z17 reviewEven more Edge gestures - Nubia Z17 review
Even more Edge gestures

Swiping on both edges simultaneously can be set to adjust the screen brightness. Again, the Z9 allowed you to use the gesture alternatively as a volume control. An up-down-up-down gesture on one edge can only be set to accelerate the phone, i.e. close running apps, complete with a cool animation. Double clicking the edge can double as a back button.

OK, thats it, right? No more gestures, smart features or anything of the sorts to make using the Z17 more like a rocket ship. Well, no. Actually, there are a few other gestures that dont pertain to the edges of the phone and this were deemed unworthy to be placed under the "FIT" moniker. Lets pretend that made any sense to begin with...

Even more gestures - Nubia Z17 reviewEven more gestures - Nubia Z17 review
Even more gestures

Anyway, you can double tap the display to wake the Z17. Also cover the screen to lock it. Realistically, we probably see ourselves remembering these two and using them at least a few times more than the convoluted edge-based finger-twisters. There are also a pair of three finger gestures, which we frankly didnt even have the energy to research them at this point.

Smart sensing gestures - Nubia Z17 reviewSmart sensing gestures - Nubia Z17 review
Smart sensing gestures

Whats that you say? You think the Nubia Z17 is pretty nice, but it could use some extra control gestures? Dont worry, theres more! Try "Smart sensing" on for size. You can pick up the phone to dial or answer and flip to mute or pause playback. Also, shaking the phone can be used to "conveniently" invoke the "Accelerate" feature. By the way, shaking the phone will also align you icons while you are in a very specific part of the Launcher settings menu. Does that qualify as another gesture? It might as well do. We wouldnt want anyone to think the Nubia Z17 doesnt have enough control gestures.

Oh, oh, we almost forgot, there is a magnification gesture hidden away in the Accessibility menu as well. Also, something called "One-key Exchange smart installation", which may or may not be a gesture and a trio of other options, which we can only assume are only useful in China, since Nubias translation team didnt even bother to translate them in English.

There is also a quick toggle for the flashlight here, scheduled power off and on and even a toggle to disable the standard Android button combination for grabbing a screen capture. Nubia does provide the option to use a press on the fingerprint reader for that instead, so we guess it sort of makes sense.

Other added features - Nub   ia Z17 reviewOther added features - Nubia Z17 review
Other added features

Speaking of confusing China-centric options, there is a WeChat Red Packet Assistant. There is also a Remote Camera feature that allows you to control another Nubias camera remotely. It is an interesting concept, but it is rather baffling why Nubia decided to put a shortcut to it in the "More Features" settings menu.

Synthetic benchmarks

The Nubia Z17 is a true flagship offer and a beastly one at that. It is built around the latest Snapdragon 835 chipset. This means a potent 4x2.35 GHz Kryo & 4x1.9 GHz Kryo CPU setup and Adreno 540 GPU. Naturally, this lets the Z17 rub shoulders with the cream of the crop on todays smartphone market.

Nubia Z17 review

The Snap dragon 835 powerhouse is still found in only a number of handsets. These include the likes of the Samsung Galaxy S8 and S8+ pair, Sony Xperia XZ Premium and HTC U11 - all more expensive than the Z17. However, there are other rivals out of China which have also taken up the hard task of integrating a Snapdragon 835 chip on a budget - most notably, the OnePlus 5 and the Xiaomi Mi 6. In a perfect scenario, free of all the additional availability and support concerns, these are the contenders the Nubia Z17 has to face and beat.

Making it in this fairly new, ultra-value, sub-$500 niche is probably one of the toughest challenges a manufacturer can take up in 2017. After putting the Z17 through its paces quite thoroughly, we are happy to report that it aces the performance round.

Kicking things off with the pure CPU-based GeekBench, we can see the Nubia Z17 hold its own with a multi-threaded workload and even out-inch the other Snapdragon 835 phones in single-core tests.

Now, it is important to note that Nubia has included a special per-app Performance mode in Nubia UI 5.0, that promises to push the phone that extra bit harder for a while at the expense of more heat and a bigger battery draw. Naturally, we gave it a go, but the difference in purely synthetic performance wasnt all that big. On the flip side, the phone did start to heat up quicker, so we opted not to use it.

That being said, all the posted results are achieved without any additional trickery or boost modes. There mere be a more noticeable performance difference in certain real-world scenarios, but during our tests, we really didnt manage to trip up the Z17 not even a tiny bit. And we tried. The Snapdragon 835 simply has more than enough pow er to go around, without any additional tweaking. It is also worth noting that we have the 6GB RAM version of the Z17. We dont really think having 8GB will net you any significant performance improvements either, but thats a topic for another discussion.

Basemark OS 2.0 is a little bit less kind to the Nubia Z17, but its score is still nothing short of impressive. We have to confess that our original expectations for the Chinese review unit were pretty low, considering all the add ed bloat the ROM is lugging around. As it turns out, however, Nubia is keeping a tight grip on the background activity and other unnecessary loads.

The Z17 shows off some impressive muscle in the graphics department as well. We are just a little bit skeptical of the Open GL 3.0 and 3.1 off-screen scores, since 3 frames is a big difference on the exact same Adreno 540 GPU. Regardless, the Z17 definitely performs on par with the competition.

The Nubia Z17 clearly has some trouble with synthetic tests. Some of the results we got are a bit suspiciously high, while others fall just a little short. After some careful evaluation and a lot of re-tests, with and without Performance mode, we are certain the Z17 makes proper use of its Snapdragon 835 chipset and can live up to the flagship performance expectations that come with it.

Most inconsistencies we recorded seem to be linked to the OS. We experienced absolutely no issues or slowdowns, while using the prone for real-world tasks. Hopefully, we can get our hands on a proper international version of the phone soon, so we can re-test everything. In case you are looking into the Nubia Z17, definitely scout out a non-Chinese version, as well. We really do think it will save you some headaches. If nothing else, Google Services are enough of a bonus in our book.

Telephony and loudspeaker

The phonebook is fairly standard, a part of the same multi-tabbed app as the dialer. You can assign personal ringtones for each contact and scan a business card to quickly add a new contact. Since there are no Google Play services (on this Chinese version) you cant count on getting your phonebook synced with the initial setup.

The final tab of this app is titled "Yellow Page." That includes local listings, complete with search. It is in Chinese only and is a pretty common feature for this local market. Sadly, we couldnt really try it out.

Phone app, contacts and Yellow Pages

The dialer shows your recent calls with the keypad on top (which can be hidden to make more room for the call log). Smart dialing is enabled - that is you can quickly search your contacts by typing - but the phone also pulls numbers for various shops and businesses from the Internet. The Info button next to each number shows more about that business.

Popping two SIM cards into the Z17 also gives you the appropriate options, like a second call button.

In our loudspeaker test, the Nubia Z17 only managed to score an "Average" mark. Granted, it is only a single point short from the "Good", but we still wouldnt count on catching all calls in loud environments. Plus, with a single speaker, it cant really come anywhere close to the impressive experience the ZTE Axon 7 delivers.

Text input

Just like the Nubia Z11 and the Z9 before it, the Z17 relies on the Android AOSP keyboard by default. It has come a long way and is actually pretty decent. Nubia used to bundle TouchPal as well. However, it now seems to have its own custom solution.

It is clearly geared towards Chinese input and has the according layouts and writing recognition. It also comes bundled with voice typing and emojis. It still features Latin characters, so it can technically be used in a Western setting as well.

Messaging

Like the dialer, the messaging app lets you easily send a message from either SIM card. Once you open a message thread you also get a clear indication of which SIM card received a given text too. The app itself looks like it belongs on iOS, it has a fairly clean UI but its functional.

Nubia Messages app

Oddly enough, it features a second dedicated tam for service messages alone. Kind of an odd choice, but again, it might be more useful than we think within China.

In the absence of Google Play services and thus a Gmail app, you do need some sort of alternative e-mail client. Nubia has provided a pretty clean and functional one. However, it had some odd issues reconnecting reliably to the Goggle mail server and we didnt manage to grab some screenshots from it. Kind of makes us wonder if there isnt some DNS or other type of traffic filtering going on the the background, since Google services arent really welcome withing China.

Come to think of it, the default browser does seem to go through some odd redirects when accessing pages from time to time. It is probably best not to dwell too much on it, avoid purchasing non-international units and hope for the least amount of traffic sniffing beyond that.

Assorted apps

If you thought the Nubia Z17 has a surplus of additional gestures, wait until you see the default app package. To be fair, some of it is necessary in the absence of Googles industry standard apps. There are a few pretty nifty tools as well. However, most of the pre-loaded apps are either in Chinese or they are not functional or practical to use outside of China.

All the basics are nicely covered. You get a Clock app, Calendar, File Browser, Calculator, a stopwatch and a flashlight. Although, we really think the latter simply belongs on a quick toggle in 2017. (Just to clarify, it is a quick toggle as well, but we still find the single picture, single but ton app interface a bit unnecessary.)

The Notes app is definitely nice to have and so is the Weather one, at least in theory, that is. For some reason, its database only includes cities within China. In contrast, the Remote app for the IR blaster is really well made, full-featured and does not mind being used abroad. Its database of appliances is surprisingly rich.

The quick shortcut to the Update menu is kind of convenient. So is the simple mode, although it doesnt really clean up the interface that much, nor make it significantly bigger and easier to see. It is also really easy to exit, which is counter intuitive if you intend the phone to be used by children or elders, or other similarly non-tech savvy users. Given its level of complexity, that sounds like a real possibility.

The projection app and nubia Roaming helper also look potentially convenient. However, they are also clearly geared towards Chinese customers. One requires a WeChat account to negotiate the connection and the other only offers data plans in Asian countries.

Image Gallery

The image gallery is pretty straightforward. You get a Photos tab with a timeline of all your shots and an Albums one, for organizing things. There is also a Cloud tab for accessing your Nubia storage account.

Music player

The Nubia Music player features a really polished UI. There are plenty of search and sorting interfaces to explore. Perhaps even a few too many. It will also automatically look for lyrics to display while playing the track, though it failed to find the words to some very popular tracks. This is likely a regional issue, rather than a small lyrics library.

Some or the automatic sorting and organization algorithms misbehave as well. Some tracks dont end up in the same artist category, despite having all their ID3 tags and getting properly placed within the same album. Automatic artwork download is also dodgy.

By the way, the Z17 has a 24-bit/192kHz audio DAC, so quality does not disappoint. There is also Dolby ATMOS multi-channel audio support along with the fancy equalizers an all. It should cater well to most every audiophile out there.

One of the few bonuses we got for reviewing a Chinese Z17 unit is Nubias cloud music service. Actually, we saw numerous Xiaomi brandings all throughout the online library, so we arent exactly sure of its ownership. Perhaps, the two companies have some sort of a deal.

What is even more perplexing is the way the online platform handles copyrights. Most "top charts", "hits" and other popular curated playlists of the sort seem to play without any legal or other issues. You can even select individual songs and we didnt notice any sign of advertising either.

Nubia online music platform - Nubia Z17 reviewNubia online music platform - Nubia Z17 reviewNubia online music platform - Nubia Z17 reviewNubia online music platform - Nubia Z17 review
Nubia online music platform

Searching for a specific song or artist often hands out an empty result list, which is understandable, given the origin of the service. But even if you do manage to find something you like, once you are outside the curated lists, copyright errors and grayed out songs that refuse to play start popping up. Its an odd and inconsistent experience for sure.

Video Player

The Video player is fairly simple in terms of UI but very capable. Videos up to 4K resolution are supported with the AVC (H.264) codec, HEVC (H.256) also works. AC3 is also supported to some extent, but 640 kbps seem to be about as much as it can handle. Things like TrueHD 7.1 and Loseless ATMOS are definitely a no-go.

Capable video player

The app is even nice enough to let you toggle between hardware and software video decoding, just in case the Snapdragon 835 fails to handle some more exotic format on a native low level and needs the powerful CPU cores to pick up some of the slack instead.

Oddly enough, Nubia still hasnt included subtitle support. You can, however view the video in a small floating window.

Nubia browser

Since it surprised us so pleasantly with the excellent battery endurance scores, while also confusing us equally with some of its behavior, the d efault browser deserves some attention. It is a custom app, likely developed by Nubia, although the interface does remind us of something along the lines of past version of UC Browser or Dolphin, but we cant quite put our finger on it.

Regardless of what core it is based on, the Nubia browser looks to be working well, but is clearly targeted at Chinese users. As mentioned earlier, hitting up a site directly by URL sometimes leads to some odd redirects through suspicious addresses. Perhaps its some data saving proxy setup, then again, we didnt really feel sure enough of this theory to submit our log-in details through it.

There are quite a few options available out of the box as well. You can disable images, toggle night mode or change the default font. Then there is the ad block feature which simply decided to kill the JavaScript in our battery browser test suite. It is fair to say it is quite aggressive, so you might have to kill it when inevitably something refuses to work.

Audio output fails to impress

The Nubia Z17 passed the active external amplifier portion of our audio test with flying colors. Matching perfectly accurate output with loudness way above the average really got us hopeful that well see a great performance.

Unfortunately, when headphones come into play the picture changed completely. Volume dropped to below average and the clarity wasnt worth writing home about any more. Stereo worsened notably, frequency response started to fluctuate and a moderate amount of intermodulation distortion crept it. We were certainly expecting better given the Z17s flagship aspirations.

Trendy dual camera setup

It really seems that "trendy" with a signature design spin is what Nubia was after with the Z17. And nothing really says "2017" like a dual-camera setup. In this case, its a 12 MP, f/1.8 + 23 MP, f/2.0 setup, which is actually one of the highlights of the phone.

A 1/2.55" sensor size and 1.4um pixels are a strong foundation to build on. The Z17 adds phase detection autofocus, a dual-LED (dual tone) flash on top and the dual camera setup even allows for 2x lossless zoom. OIS is a notable omission, though.

Nubia Z17 review

Before we get into samples and quality, it is well worth praising Nubia for its excellent work on the camera app. A lot of the appeal the Z17 holds as a camera phone actually stems from software more than anything else.

OK, to be perfectly frank, the interface could benefit from some more consistency. Perhaps, its high time Nubia finally used one single font for all the items in the right mode selector. Just a thought.

Other than that, it all looks deceptively simple. Besides a regular and Pro mode for still, you also get a dedicated video recorder UI with its own proper viewfinder, as well as a shortcut to Portrait mode. It allows for some nifty bokeh effects thanks to the two cameras and we kind of get why Nubia wanted it front and center, instead of buried another level down with the other advanced modes. By the way, thats what the Camera Family button opens.

On the far left of the viewfinder, you get a few toggles, including HDR and the flash, both of which can be left on Auto. The options do change, depending on the mode you select, but they are all very self-explanatory. The settings wheel opens up a few quick toggles. Both face and smile detection work really well.

We dont exactly appreciate the absence of a clear and plain resolution selector for s tills. All you get instead is an aspect ratio switch. Tapping on the More settings opens the detailed settings menu, where at least the video resolution is nicely laid out for you to manipulate as you see fit (up to 4K on the main camera and 1080p on the selfie).

Camera settings - Nubia Z17 reviewCamera settings - Nubia Z17 review

Some of these options are really poorly translated and we are not exactly sure why a Beauty Face calling toggle is in the camera settings at all. Flipping through the modes in the main camera UI reveals some other confusing titles, but their meaning can be extrapolated fairly easily. Again, our hopes hang on a proper international version.

But the so called "Camera Family" (surprisingly, far from the worst English translation in Nubia UI) is where the really interesting tricks reside. Multi Exposure, Light painting and Slow Shutter are pretty self-explanatory, but not necessarily basic. The first, for instance, has exposure modes. The same mostly goes for Trajectory, Star Track and Clone Camera. They are more or less variants on the multiple exposure idea.

Electronic Aperture, however, is something different. It uses Nubias Hand-held Image Stabilization technology to achieve quite impressive long exposure shots in hand-held mode. Of course, you can toggle hand mode off, grab yourself a tripod and get even more impressive shots. This simulated long exposure works surprisingly well on moving water. Shooting moving lights in the dark also produces some interesting smooth colors. Different shutter speed settings yield distinctly different results. In fact, here are a few samples.

While at it, here are a few other special mode samples. Slow Shutter gathers a lot of light and is even better for nighttime photography. Light Draw is another classic Nubia mode you can have a lot of fun with. It is mostly intended to capture light traces in the sky or car lights at night, but we found it also produces pretty nice results with flickering light sources, like an open fire. Star Trails and Trajectory are more or less variations on the same concep t.

Time Shuttle has two distinct filters on offer. One is called overlying and doubles and offsets the image and applies a few other effects. Diffusion applies some blur to the edges of the frame. Both work well for certain scenes and are really trippy.

We also had a lot of fun with Clone mode. What it does is allow you to take a few shows and layer them one over the other. The end result is quite impressive, considering the amount of work it would take to achieve the same in Photoshop or a similar editor.

The mode actually has its own little editor interface that lets you select the different areas from each frame that should end up in the final version. It is quite fiddly, but automatic detection can only get you so far (we purposefully left the defects on the table tennis shot intact). Also, certain slight exposure differences are to be expected and you have to be careful with shadows, their absence and direction. Results dont hold up to pixel-peeping, but are still visually impressive at first glance.

We definitely got a little sidetracked with all the special modes the Nubia Z17 has to offer. Lets take a step back and talk about the camera image quality in general. The Z17 holds up quite well. By default, still get captured in 12MP in Auto mode, with the phone doing all the heavy lifting of combining data from both sensors seamlessly behind the scenes. There is plenty of resolved detail and noise is kept at bay well. This is achieved while maintaining a fairly laid-back level of processing. That means little to no noise reduction artifacts, at least in good lighting conditions.

However, the Nubia Z17 is far from perfect and still has its issues. For one, colors seem to be a little dull in most stills. This is especially true when we compare them to the OnePlus 5 samples, which are far from perfect themselves, but do seem to offer quite a bit more "pop". Granted, preferring one over the other is mostly a matter of taste.

What is far less subjective, though, is the "trigger-happy" spot exposure metering algorithm. Tapping on the viewfinder can easily result in drastic exposure shifts. Frankly, you are better off just letting the camera app dec ide on its own, if you dont intend to fire up PRO mode and really get hands-on with a given shot.

HDR goes way overboard in terms of exposure as well. The Z17 is typically smart enough to know when a shot would benefit from the mode, so the Auto setting does work as intended in this respect. However, you might want to keep it off regardless.

There is surprisingly little noise in low-light conditions as well. The noise suppression algorithm scales up its effect gracefully and does a lot more work when t he lights go down. Still, detail is plenty.

Nubia has taken full advantage of all the potential benefits its dual-camera setup can provide. The Portrait mode, so prominently featured on the main camera interface, uses data from the pair of shooters to create impressive bokeh effects. Of course, the effect is still created digitally in its essence and some errors with edge detection a re to be expected - especially when your subject a busy background. That being said, we are quite impressed with the results the Z17 produces.

The Z17 can also capture some very up-close and personal shots in its Marco mode. The manual focus slider offers an astonishing level of precision. Just look at the slight shift on the red truck from only a few centimeters away.

DNG mode is really neat. It allows the Nubia Z17 to save stills in uncompressed RAW mode. But the really nifty part is that you can choose which of the two cameras to use. In auto mode, the phone takes over all such features to ensure the best possible shot by taking info from both sensors. You can see the difference in resolved detail for yourself below.

Of course, these are the compressed JPG images that the phone is nice enough to save alongside the DNG, which we sadly cant visualize on the web. One is a 12MP sample, the other 13MP. You can clearly see the difference in aperture between the two lenses as well.

We also took the DNG files themselves and gave them a quick Photoshop treatment to see if we could get more out of them. While we did manage to get a bit more dynamic range and slightly better colors with more precise sharpness control, the difference was marginal. The Z17 really does a good job of processing its stills. You can download the RAW files here and here and below are our processed JPGs.

The Z17 also does a great job of capturing panoramas. Detail is plenty and there are very little stitching defects and artifacts visible in the end result.

Last, but not least, here is the Nubia Z17 in our photo compare tool. You can pit it up against any of the other devices in our database for some pixel-peeping evaluation. You might notice that the framing oh the posters isnt exactly right. The fact is the Z17 suffers from some barrel distortion. The image processor seems to be taking care of most of it near th e center or the frame, but for some reason, it gets really bad near the edges.

There is a 16MP, f/2.0 camera on the front side of the Nubia Z17. It is a fixed-focused unit and lacks any other extras, like a dedicated flash. However, it still does a bang-up job. Detail is plenty. Edge to edge sharpness is great as well. The only thing we really miss from the experience is some form of software bokeh effect, to go along with the Portrait mode on the back. But were nitpicking.

The sweet spot for the selfie camera fixed focus is set a little far in our opinion and you need to hold the phone at a full arms length from your face to get your mugshot nice and sharp. Still, missing it by a little is not a big issue.

Just like with the main camera, the Nubia Z17 does a good job of processing low-light selfies, with minimum amounts of noise and really noticeable traces of the noise reduction doing it s work.

Video

The Nubia Z17 can capture videos at up to 4K on the main camera and 1080p for the selfie one. Besides the standard 4K@30fps and 1080p@30fps, the phone also supports 1080p@60fps recording for smoother results. There are no fancy slow-mo or other high frame rate modes beyond that.

Clips get saved in MP4 format, with an AVC video stream and 48 kHz, stereo AAC audio to go along. Bitrate is pretty respectable and keeps relatively stable at about 42 Mbps at 4K, 40 Mbps at 1080p@60fps and 20Mbps in 1080p@30fps, respectively.

Despite some noise here and there, 4K quality is definitely flag ship-grade. Detail is great and even the colors look a bit more vibrant than on stills. Here are a couple of samples.

Even in low-light conditions the Z17 delivers impressive video results.

Frankly, the only thing we really missed during our time with the Z17 was video stabilization. It seems Nubia made little to no effort to counter shaking. We have a pair of clips to show exactly how bad it is in 4K and 1080p.

FullHD capture on the Z17 is a lot less impressive than its UHD alternative. There are some really obvious compression artifacts. W eve definitely seen worse, but were also sure Nubia can do better.

You can, of course, download untouched video samples, the way they came out of the Nubia Z17. Theres a full set from the main camera (2160p, 1080p/60fps, 1080p/30fps)

And to top things off, here is the Nubia Z17 in our video compare tool, both in 4K and 1080p. Again, the barrel distortions played a major number on our framing.

Final thoughts

There are a few different ways to look at the Nubia Z17 but It definitely meets the admission bar of the 2017 flagship club. With a price tag south of the $500 mark and therefore just the right bit cheaper than the OnePlus 5, the Nubia Z17 is probably the most affordable package with a Snapdragon 835 under the hood. This couldve been calculated or coincidental, but ZTE didnt stop there and the phone deserves some credit for trying to over-deliver in terms of audio and imaging too.

Nubia Z17 review

Part of a c continuing effort to raise ZTEs prof ile outside of China and Southeast Asia, the Nubia brand has always had a little extra leeway to experiment with design. Taking full advantage, the Z17 sticks to the signature look of a pretty unique product line. The special Nubia style is there in spades. With its bold new color pallet, curved screen and gesture-driven interactions, the Z17 is genuinely trying to be different. Granted, it is still very much an acquired taste, but if it just happens to appeal to you, there are very few alternatives, if any, in that price bracket.

Nubia Z17 key test findings

  • The Z17 employs a distinct visual style and upholds the signature Nubia look. A throwback to the original Z9 but with a sharper outline and a new selection of bold and vibrant colors. It is sturdy and well built, but quite slippery to hold.
  • The Z17 has no 3.5mm audio jack, but is one of only a few devices to s upport analog audio output through a USB Type-C port, with a passive adapter. Its touted as the first Quick Charge 4+ compatible device but the supplied charger definitely does not support the standard.
  • The 5.5-inch FullHD IPS LCD is about average in terms of performance. It is bright enough and works acceptably well outdoors. Color accuracy is really off.
  • Battery life is surprisingly good at 81 hours, considering all the pre-loaded bloatware. The Nubia UI 5 manages background tasks really aggressively. The default browser might be dodgy, but appears to be well optimized for power efficiency.
  • The user interface is literally filled to the brim with extra features and custom gestures. The off-edge gestures are still one of Nubias calling cards, but the rest of the features, piled on top are just impossible to remember and utilize properly.
  • The Chinese version of the Nubia UI ROM is really tailored to the local market. Many features dont work as intended or at all. English translations are also poor, with some options not translated at all. There should be an international ROM to hopefully remedy all that and add Google Play Services to the mix.
  • The Nubia Z17 does really well in synthetic benchmarks (both CPU and GPU). The Snapdragon 835 is a strong performer, easily on par with other current flagships.
  • The Nubia Z17 outputs outstanding audio with an external amplifier. However, performance with headphones is only average.
  • Still images from the primary camera are very detailed with more laid-back processing and noise reduction yet virtually noise-free. The phone performs well in low-light conditions as well. Contrast is a little bit lacking.
  • Nubia 5 offers one of the most feature-rich camera experiences we have seen to date. All the manual controls are really powerful. Most of the added special modes work really well and produce interesting and unique results. The camera interface could use a makeove r for the sake of better consistency and organization.
  • Portrait mode on the main camera works surprisingly well. We miss a similar feature on the selfie cam. The front camera captures pretty nice photos as well, with plenty of detail and little noise.
  • 4K video capture is flagship-grade, with plenty of detail and a nice and steady bitrate. 1080p video shows significant signs of compression and could use some work. The lack of OIS or EIS is the only significant omission in the video recording experience.

Now, before you start Googling for an international Nubia Z17 (and you really want the international, not the Chinese version, believe us on that one), it is worth considering that the phones unique nature entails a few potential caveats. First, there is the availability and support argument. In this case, mixed with some significant localization issues. You simply have to check locally how convenient and cost-efficient it actually is to own and support a N ubia where you are.

Then again, since the OnePlus 5 and Xiaomi Mi 6 are probably the prime alternatives, well assume you know what you are doing and can live with the implications of getting a phone shipped overseas. As for the compromises, the Nubia Z17 skips on some basic or should we say, desirable features. Expandable storage, some form of ingress protection, video recording stabilization and OIS, stereo speakers - some of these things can be had in a budget of $500 or less.

Starting off with the value flagships, the OnePlus 5 offers quite an understated look compared to Nubias extravagance - not necessarily a bad thing, especially if you are shopping for a business phone. What you are still getting is the powerhouse Snapdragon 835 chipset, as well as a gorgeous, infinite contrast Optic AMOLED panel, among other things.

If you have $500 to spend, Xiaomis lineup has you pretty much spoiled for choice (add or take the potential import taxes, of course). If you really have your heart set on the Snapdragon 835, then the Mi 6 is the most obvious option. However, you will have to live with a rather compact 5.15-inch LCD panel. There are always the slightly less powerful Mi 5s Plus and Mi Note 2 to meet the big-screen demand.

Need something with a more Western-friendly face? Easy! The LG G6 is the most affordable of this years big-name flagships, virtually matching the OnePlus 5 and Nubia Z17 at this point. Going for the G6 will get you a sharper (and, um, taller) display, and a very different take on the dual camera concept - LG likes its secondary cam ultra-wide, and so might you. Expandable storage and water and dust protection score points for the G6 too. You do have to settle for a Snapdragon 821 though - still an awesome deal in our book.

The Galaxy S7 edge is last years hardware, but it can be had for pretty much the same price in a lot of places. Its dual curved QHD Super AMOLED is both brighter and sharper, not to mention more power efficient than the LCD on the Z17. A 16MP primary cam with 2x zoom (sort of) and portrait mode and IP68 protection are also part of the package.

And in case a phablet is what you are after, the HTC U Ultra might be worth a look. A 5.7-inch QHD panel and 2.05 secondary display are plenty of screen real estate to work with. Plus, you get a potent OIS-enabled 12MP camera with laser & phase detection autofocus. The Huawei Mate 9 is an even more robust set, with its massive 5.9-inch LCD. Its Dual Leica-powered camera setup might even be an even better fit than what the Nubia Z17 has to offer. And you can definitely count on the in-house Kirin 960 to not let you down.

All things considered, the Nubia Z17 is not a phone you see every day. It dreams big and aims high, sometimes missing its ambitious mark and losing sight of some of the details along the way. If you do pick up a Z17, it definitely wont disappoint as long as you know what youre getting into and can comfortably live with the quirks.

In the long run, Nubia still has some kinks to iron out and a lot of trust to build outside of its home market. That said, ZTEs creative angl e is definitely good enough to build a success story on, both in China and abroad. The Nubia Z17 is a chapter in that and you can tell its trying hard. Still a long way to a bestseller but quite close to a contender.
