Although it retails for less than £200, the ZUK Z2 Review has the kind of build quality you’d expect to find on a handset that costs twice, maybe three times as much.

There’s 2.5D glass on the front and rear, which rounds off neatly along the edges and appears to have some kind of coating that keeps greasy ZUK Z2 Review fingerprints to a minimum.

There’s no denying that the Z2 feels great in the hand, but the flat and glossy back panel mean that it slides off pretty much ZUK Z2 Review every surface you place it on, so it might be advisable to invest in a protective case.The edge of the device feel like plastic, but it’s actually metal covered in a matte material to increase grip. The power and volume keys are fashioned from plastic and can be found on the right-hand side of the phone.The only other physical input is ZUK Z2 Review the home button, which doubles as a fingerprint scanner and is situated below the screen. This button feels a little cheap when pressed and certainly doesn’t give the same reassuring “click” you’d get from a Home button on a Samsung or Apple device.Despite the cheap feel, the Home button hides some neat tricks. Swiping from right to left switches to the last-used application, while swiping from left to right takes you in the ZUK Z2 Review opposite direction. This allows you to multi-task and toggle between apps without having to drop back to Android’s dedicated active app screen (which is accessed by double-clicking the home button if you so wish).A single tap on the home button – not a full press – acts as the “back” command. It works really well once you become accustomed to it.With dimensions of 8.5 x 142 x 69mm, this is quite a compact device – when placed next to the iPhone 7, there isn’t much difference in terms of overall size. The Z2 is a lot lighter, however, coming in at just 149g. This gives it heft without feeling cheap and insubstantial.


ZUK Z2 is equipped with what it calls a “Super Retina Display”. This is a 5-inch screen with an LTPS IPS panel that has a resolution of 1080 x 1920 pixels and a pixel density of 441 ppi. LTPS (Low Temperature PolySilicon) panels are used in displays with large size, large resolutions and pixel densities ZUK Z2 Review because the electrons move faster through the polysilicon grains and the pixels can be placed close to one another. The panel of the model has a classic striped pixel structure. According to the official specifications the display has a 1000:1 static contrast ratio, 400 cd/m² brightness and covers 70% of the NTSC color gamut. The unit is protected by a Corning Gorilla Glass 4 with a 2.5D curved top glass layer. The same protects the back. Both have an anti-stain coating, but actually you can see smudgesZUK Z2 Review left from your fingers, more on the front than on the back. In terms of displayed content our subjective opinion is that colors are true-to-life and text rendering is excellent.

ZUK Z2 Review

According to our display measurements, our review unit has a peak brightness of 530.364 cd/sq.m. It drops more than Zuk Z2 Price twice to 237 cd/sq.m. when the brightness level is set at 75%. At 0% the white values are very low – 3.225 cd/sq.m. At the same time the black value at this level couldn’t be measured, hence, the static contrast ratio is not measurable too. The black values at all Zuk Z2 Price brightness levels decrease proportionally compared to the white ones, therefore, the static contrast ratio remains almost the same at all brightness ZUK Z2 Review levels (excluding 0%) – an average of 1100:1. The temperature of the white point is around 8600-8800K, which is higher than average (the colors look colder) displays in general, but for a smartphone display it is a normal level. In case you need to adjust the ZUK Z2 Review color temperature, you can do so from the corresponding display options from the Settings menu. Regarding the colors, the display of ZUK Z2 covers less than 100% in the red and green spectrum of sRGB, while in the blue one there ZUK Z2 Review is a slight deviation from the sRGB one. This entirely complies with the 70% coverage of the NTSC color space as officially specified. Horizontal and vertical viewing angles are very good with only a slight loss in brightness when the display ZUK Z2 Review is looked from aside.

Brightness White luminance Black luminance Contrast Color temperature

Despite the Z2’s slim frame, it houses a 3,500mAh battery – this is larger than the one seen inside the Galaxy S7 (3,000mAh), iPhone 7 (1,960mAh) and even the phablet-sized Google Pixel XL (3,450mAh).

Not surprisingly, stamina is excellent. With moderate usage I was able to make the Z2 last for almost two entire days on a single ZUK Z2 Review charge – something that doesn’t happen that often in the world of smartphones.To give you an indication of how the Z2 stands up to extreme usage, I streamedZUK Z2 Review a HD video for an hour with the screen brightness at maximum and the volume turned all the way up, and it shaved less than 10% off the battery.
Since it uses Qualcomm tech, the phone also supports Qualcomm’s Quick Charge 3.0 standard, which allows you to fully charge the battery from empty in around 90 minutes – when using the supplied charger, of course.


ZUK Z2’s performance relies on a Qualcomm Snapdragon 820 MSM8996 chipset. It has two 2.15GHz Kryo cores and two 1.6GHz Kryo CPU cores, working in tandem with a 624MHz Qualcomm Adreno 530 GPU, which handles the ZUK Z2 Review graphics. The built-in Hexagon 680 SPU is used for functions, such as the pedometer, which do not require much power. It works independently from the CPU and adds to the overall power efficiency of the chipset. More interestingly, in the latest official and stable ZUI, ZUK has provided a one-click overclock mode, which boosts the clock rate of the CPU to 2.30GHz. Obviously, without being able to update to the latest UI we cannot run the benchmark tests and actually see whether this brings any significant boost in ZUK Z2 Review performance. Our unit scored 131789 points in AnTuTu, which means that it only slightly outperforms the nubia Z11(131119) and ZTE Axon 7 (130536), taking up a third place in our chart of reviewed smartphones with a Snapdragon 820 SoC. The first place is occupied by OnePlus 3 (144140) and the second – by LeEco Le Max 2 (137549). However, when you look at the PCMark Work performance score, it definitely places the ZUK Z2 on top of all devices with 7278 points. The Geekbench 4 results are significantly lower to the results of the other smartphones, tested with Geekbench 3, so we cannot actually compare them fairly. The Basemark X ZUK Z2 Review gaming performance score of ZUK Z2 isZUK Z2 Review very close to the one of OnePlus 3. The top place in this regard is taken by the nubia Z11.

The system-on-chip is combined with 4GB of double-channel, LPDDR4 RAM clocked at 1866MHz. The built-in memory measures 64GB and is of the eMMC 5.1 type – the fastest eMMC one. This means that the PCMark Storage score and the results from the Androbench test are expected and are close to ZUK Z2 Review those of nubia Z11 and lower than those of the OnePlus 3 (the device with the fastest memory according to its scores) and the Axon 7. Of those 64GB, 58.24GB are available for the user. There is no option for memory expansion. The device also has an ZUK Z2 Review advanced sensor setup. It has a heart rate and UV sensor, pressure altimeter, three-axis accelerometer, three-axis gyro, G-sensor, three-axis compass, proximity and ambient light sensor, Hall sensor, pulse oximeter. Besides helping the device to provide ZUK Z2 Review you with immersive gameplay, they also serve ZUK’s U-Health app. The multi-functional home button has an embedded fingerprint sensor (model FPC102x), which supports wet fingerprint unlocking. It is coupled with ZUK’s U-touch 2.0 software, which supports HD fingerprint identification and self-learning fingerprint matching algorithm. This means 99.8% accuracy and fast recognition in 0.1s. From ZUK Z2 Review the corresponding section in the Settings menu, you can tweak the U-touch options and manager your fingerprint ID(s), respectively.


The camera app is pretty simple. Its home screen has a large shutter button, merged with a smaller one on its right that serves as switch ZUK Z2 Review between the front and rear shooter. On the left is the shortcut to the video function and on the right – to the gallery. At the upper end of the screen you’ll see the icon for the LED flash options (in the left corner) and HDR ones (in the right corner). In the center between them you have the camera modes icon. It opens a list with options, including HDR, flash, Pano, Scale as well as HFR (high frame rate) and LFR (low frame rate) options. If you’ve opened the selfie camera, there’s a beautification ZUK Z2 Review function with its corresponding icon in the top left corner. There are additional camera settings, which let you choose the resolution and quality of photos and ZUK Z2 Review videos, manage several sound effects, and etc. Editing a photo includes applying several filters on it, changing its aspect ratio, rotating it to the left or right, and so on.

Primary camera

In order to appeal to fans of photography, ZUK Z2 has chosen a 13-megapixel Samsung S5K2M8 ISOCELL sensor with a 1/2.6″ size. This sensor is seldom used in mobile devices. The only other devices ZUK Z2 Review that have it are the 360 Q5 and Q5 Plus. ZUK has coupled it with a 5-element lens with an f/2.2 aperture, single LED flash, and a dual-mode focus, which joins phase-detection autofocus (PDAF) with continuous autofocus (CAF). The latter is used for fast moving ZUK Z2 Review objects as it detects their movements and refocuses accordingly to keep them sharp. The images are with a resolution of 4160 x 3120 pixels, while the top video resolution is 4K (3840 x 2160) @ 30 fps.

Secondary camera

The front camera features an 8-megapixel, 1/3.2-inch OmniVision OV8865 sensor with a 1.4-micron OmniBSI-2 pixel and a 78.9° wide-angle lens. The sensor’s model has been announced three years ago, but still it does a very good job in this smartphone. The images are with a resolution of 3264 x 2448 pixels, while the top video resolution is 1080p @ 30 fps.

Networks, calls and connectivity

ZUK Z2 has a dual SIM card slot for nano-SIM cards. Only the first slot supports 4G LTE Cat. 6 for up to 300 MBit/s in downstream and 50 MBit/s in upstream. The second SIM card works with 2G and 3G connections. The network bands supported by the device include 2G GSM (850, 900, 1800, 1900 MHz), 2.5G CDMA 800 MHz, ZUK Z2 Review 3G W-CDMA (850, 900, 1900, 2100 MHz), 3G TD-SCDMA (1880-1920, 2010-2025 MHz), 4G FDD-LTE (850, 900, 1700/2100, 1800, 1900, 2100, 2600 MHz), and 4G TDD-LTE (1900, 2300, 2500, 2600 MHz). Call quality has been excellent at all times, both for the caller and receiver. The rest of the model’s connectivity Zuk Z2 Price options include dual-band Wi-Fi a/b/g/n/ac, 802.11n 5GHz, Wi-Fi Hotspot, Wi-Fi Display (Miracast), and Bluetooth 4.1. Wi-Fi reception has been stable and setting up the device for its various wireless connections is quick and easy. There’s a ZUK Z2 Review USB Type-C 2.0 and NO OTG support. The model operates with the three main satellite systems – GPS, Glonass and Beidou, and has managed to detect a good number of satellites from all three with an accuracy of up to 3 meters. There are additional ZUK Z2 Review connectivity services such as setting up a Private Hotspot, VPN, and Roaming service, which can be accessed from the Advanced Settings. There’s also a Network ZUK Z2 Review Settings Reset function, which is separate from the Factory data reset.


ZUK Z2 shows audio results that are only very slightly better than those of an average smartphone. The test has been performed by ZZUK Z2 Review using the the RightMark Audio Analyzer software and the TASCAM US-2×2 audio interface. The device does not have any special audio equipment and has a single speaker placed at the bottom frame next to the USB Type-C port. Yet, the sound from it is ZUK Z2 Review good (subjectively speaking). ZUK uses Google’ music app, instead of providing one of its own, and it does not have any advanced audio settings. Under the Sound options from the Settings menu you can choose to calibrate your headset buttons.

OS, UI and software

ZUK Z2 runs Android 6.0.1 Marshmallow out of the box with ZUK’s proprietary UI on top – ZUI 1.9. The ZUI version our review unit has is 1.9.077-ST. It is bound to be ZUK Z2 Review updated to the next stable ZUI version – 2.0, but since ZUK’s servers are geo limited (access from China only), the update could not happen over the air. So we’re currently reviewing ZUI 1.9. This is the adapted English version, but still has some apps and settings in Chinese. This user interface differs in ZUK Z2 Review many ways from the classic Marshmallow one and other custom UIs we’ve reviewed. The lock screen allows access to the camera app by swiping it to the left. Swiping up unlocks the device. Notifications and access to the Quick Settings on the ZUK Z2 Review lock screen are allowed by default, but you can change that from the Settings menu. The home screen has a docked row of apps, which includes the Dialer, Messenger, Browser and Camera. Above it there are two rows of on-board apps. You can swipe the ZUK Z2 Review screen to the right, which gives you access to the U-Health app. Swiping to the left allows you to navigate through the various desktops with apps. There’s a Tools folder containing several apps inside, but the interesting thing about it is the option to rename the folder. Once you open it, you’ll see a blinking cursor next to the folder’s name and you can change it. There is no Widgets menu in ZUI. The only ZUK Z2 Review thing that is widget-like is the clock and weather app on the home screen, which you can edit. A long press on the home screen opens up an option for re-arranging the apps. Another major difference is the access to the Quick Settings. You have to swipe up from the bottom of the screen to open it. It has two screens, the second is Zuk Z2 Price accessed by swiping from the first screen to the left. From the Settings menu you have toggle options for the Quick Settings. The Notifications can be opened by swiping down from the top of the display. The volume screen has two options – system and media sound volume. When you press and hold the power button you get access to the reboot menu. It includes two options only – reboot and power off. A double Zuk Z2 Price press on the home button opens the list of active apps. If you swipe down an app, you will lock it, thus protecting it from cleaning. To unlock it – swipe down again.

The Settings menu is deeply reorganized compared to a standard Marshmallow one with many options brought up a level or ZUK Z2 Review two above, so they are accessed more easily and quickly. It starts off with the connectivity options, which include all standard ones. More interestingly, options like Roaming services, Personal Hotspot and VPN connections are placed in a totally different section named Advanced Settings. The first menu after the connectivity one is the U-Touch, which manages the behaviour of the home button of the device. As mentioned earlier, it is both ZUK Z2 Review touch- and pressure-sensitive. From this menu you can adjust its behaviour as a navigation button, while its function as a fingerprint sensor is managed from the corresponding menu. The Notifications & Statusbar set of options is extensive and lets you adjust which apps should produce notifications and which not. You can also toggle on ZUK Z2 Review and off the badge appearance on three apps – Messenger, Dialer and System updater. This section also includes options for the Notification light, which is switched off by default. Third come the settings for the Quick menu. You can change the switching ZUK Z2 Review sequence and toggle the shortcuts.
ZUK does not rely on colorful themes and wallpapers to attract the user. It lets you choose from several beautiful wallpapers available on the smartphone and many more, which can be downloaded for free. You can switch on a daily wallpaper function and HD desktop wallpaper. You also have four skins ZUK Z2 Review to choose from – the default one, black, blue and red. ZUI gives you a choice of various fonts, however, they are available only for Chinese. The Display settings allow you to switch on a Night Color mode, which warms up the display. If it is switched off, you can choose from cold, standard and warm color options. From here you can also ZUK Z2 Review change the text size and set a screen timeout. The Sounds & Vibrate section includes the standard Volume, Vibrate, DND, Ringtones, Sound notifications, but also a Headset buttons calibration. The Fingerprint & Passcode menu lets you ZUK Z2 Review set up your fingerprint ID(s), which is fairly quick and easy. You must set up a PIN, password or pattern in order to activate a fingerprint ID. However, when you delete the ID, the passcode you have chosen remains.
The Security settings are not as extensive as those in the classic Android M. They include a Screen pinning option, app permissions settings and strangely – the location mode, which has more to do with connectivity and ZUK Z2 Review battery usage. The Advanced settings include options for the Date & Time, Language & Input, Account synchronization, Auto power on/off (Scheduled…). Under this section you can also monitor and manage the battery, storage, applications, several connectivity functions such as Personal Hotspot, Roaming and VPN, Network settings reset and a separate Factory data reset. It also contains the standard ZUK Z2 Review Accessibility options. The last section of settings includes the Cloud Service, for which you must have a ZUK account, the Phone/Call, Contacts, Messaging and Camera settings. At the end are the System updater and About phone details. ZUK’s servers ZUK Z2 Review are geographically limited to be accessed from China only and an OTA update outside the country is impossible, unless you use a reliable VPN service or other tools (not OTA) to install the update.
ZUI is very clean in terms of pre-installed apps. Its Chinese version is much richer, but we are reviewing the adapted English one (official). Unlike the Chinese version, this one has Play Store pre-installed along with Google Play ZUK Z2 Review Music and Calendar. You get all the standard apps such as Dialer, Contacts, Messenger and default Browser. The Dialer has an option to switch the its additional ZUK Z2 Review menu to the left or the right of the dial pad. This menu has an integrated shortcut to Yellow Pages in Chinese. The Calculator seems to be standard, but theZUK Z2 Review Clock app is modified and has four different screens for the alarm, clock, stopwatch and timer. Another app that is in Chinese and needs a ZUK account is the U-health one.
Of course, there is a File Manager, along with a Gallery, Camera and a Weather app. The Tools folder contains the Sound Recorder, Calculator, Compass and a shortcut to the System Updater. The compass can be calibrated and contains a level tool as well. Finally, there’s an app called SafeCenter. Some of its settings ZUK Z2 Review are in Chinese, but the main functions are in English. The first one is the storage monitor, which can assess memory usage and suggest clean-up services, so you get the most out of your storage and accelerate the device by freeing RAM. The second ZUK Z2 Review screen of the app is called AntiVirus, but contains various services such as Accelerate (again by freeing RAM), Space Cleanup (by optimizing apps), Data Usage monitor, Autostart app toggles, App Permissions toggles, and Anti-Spam options.


The Zuk Z2 shows just how far mid-to-budget range Android phones have come in the past few years. Not only does it pack a powerful ZUK Z2 Review processor, 4GB of RAM and plenty of internal storage, it also has a great screen, gorgeous design and creature comforts such as quick charging and a super-responsive fingerprint scanner.This aside, the Z2 is one of the best low-cost Android phones money can currently buy. It ticks all of the right boxes regarding power, battery life, photography and ZUK Z2 Review build quality, coming close to the standard you’d expect from a handset that costs £600 or more.
