ZUK Z2 Pro: the best Chinese product at a modest price. ZUK Z2 - Technical specifications
The situation when a large company produces part of its products under other names is no longer surprising. Moreover, this happens in various spheres themselves. In some cases, such solutions are important for the market of the singing power, and sometimes the premium and flagship segments are seen in the brand.
Thanks to our partner - the Cheap-mobile online store, let's take a look at the new Zuk model. It’s not good to take advantage of the low popularity of a brand, since we are left with a subsidiary of Lenovo.
In the past, we have already tested the Zuk Z1, a long-lived flagship with Cyanogen OS 12 on board. They didn’t show any special respect that time, and we won’t forget that little note for the first time. Moreover, when choosing in the laboratory The best mobile solutions for 2015 This device has become a winner in the category “The Best Flagship “Tablet Phone”.
Now the manufacturer has presented a new flagship at a reasonable price - Zuk Z2 Pro, a name you can guess about the top model Lenovo Vibe Z2 Pro. And it’s unlikely that you got away with everything, having swiped for everything, so they indicated that the new product was soft.
Let’s take a look at the hero in a standard way, but in the world of tests we will pay attention to the important features that were not previously featured in Lenovo devices.

In addition to its over-extended characteristics, the Zuk Z2 Pro also comes with a number of additional functions, which will be discussed below.
Packaging and accessories Zuk Z2 Pro
The device is packaged in a white cardboard box of medium size. There is a flat surface that consists of the main section and the cover, which covers the end halfway.
The cardboard is thick and thick to ensure effective protection. The middle of the cover is glued with a soft material for maximum fitment. There is nothing wrong in the middle, the skin element of growth is strictly in its place.
On the front side there is also the logo of the manufacturer. And the axis on the upper and lower ends of the cover contains Lenovo logos, so no one is aware of this fact.
The back side of the big one is empty, except for the sticker special numbers And basic characteristics in Chinese language brighten up the picture.
The device itself is in our midst. The wines are fixed in a special binder, as well as secured with shipping foam on the display.
Under it there is an envelope with documentation and a paper clip for removing the tray for the SIM card.
At the very bottom there is a standard delivery kit including a food adapter and USB cable. Unfortunately, we were given a copy without a cable for testing.
The delivery set includes:
- Life adapter;
- USB 3.1 Type C cable;
- Clip for the SIM card slot;
- Technical documentation.
We were pleased with the brightness and firmness of the packaging, as well as the sufficient delivery set. It’s easy to understand what you have to do when transporting it, so that any damage you want will happen. Perhaps the only doubtful point is the absence of factory seals. It is important for Varto to carefully inspect the device before purchasing.
The ZUK brand has become more prominent with the release. Processed with CyanogenMod membrane and removed good vibes looking around at the price. Now we present the ZUK Z2 device, which is no less impressive in terms of price and performance.

play
The Qualcomm Snapdragon 820 is powered by the Adreno 530 graphics chip, which can easily handle all kinds of games, including those from 2016. This same GPU is used in flagship smartphones and a number of others.This review looked at productivity in the games Modern Warfare 5 and Asphalt Xtreme, and no problems were identified.
Android
One of the main problems of this smartphone. ZUK Z2 runs on a highly modified Android versions under the name ZUI. It looks like it will be similar to systems based on iOS and MIUI, but it won’t work. The information center is absolutely dumb, it’s hard to quickly look at it, the lock screen cannot work with multimedia content management elements. Additionally, adjustments have been made to eliminate important sections, simplifying the process of making changes to the system.
And two versions of ZUI: one for the Chinese market with no installation of add-ons, the other for the Indian market, more suitable for work. In the rest, there are various extras for Google and little “bloatware”. But it has its own peculiarity, since it is updated earlier than the Chinese version. The updates to the Indian version are larger and come out earlier.
Outsiders are welcome software products, Including the stable (or unofficial) version of CyanogenMod 13 and the beta version of CyanogenMod 14.1 to 7.1. A number of assemblies not related to CyanogenMod, including the AOSP version of Android. The kernel and other files are available for ZUK, so developers have more room for creativity.
Camera
The productivity of the chamber is average. On paper it has poor characteristics (recording at 120 frames/s, 4K support), with well-lit photos coming out great. If there is too much light, it is important to adjust the exposure, and if there is too little light, it is important to focus.
battery
The Z2 has a battery capacity of 3500 mA, but it seems that it does not drain properly. The fact is that with 5.5-inch devices on the Snapdragon 820, their autonomy is greater, lower than that of the ZUK Z2, for a year or two when the screen is on. With inactive victorians, for three years listening to podcasts, periodically listening, reading by e-mail, Browser and may be without dzvinkiv, with an active screen, the device was used for three and a half years, after which 15% was lost. The reason may be related to the operating system and may be covered by future updates.

External appearance and ergonomics
The ZUK Z2 looks even simpler, and this fact has two consequences: on the one hand, the design of the smartphone may seem boring to consumers, on the other hand, we have been spared suffering through a lack of taste. In terms of materials, the Z2 body does not fit into the current trend; the body is not aluminum and does not have an aluminum frame, but is made of plastic with fiberglass as a base. The surfaces (front and back) are covered with a 2.5D curved surface with an invisible tread.
All control elements are handcrafted. The smartphone has a finger scanner that works with the touch Back button and the mechanical Home button. Double-pressing the mechanical DoHome button will bring up the screen of running applications, in addition to swiping on touch button left or right you can switch between neglected add-ons. There are no classic touch or on-screen Back and Multitasking buttons in the ZUK Z2. The fingerprint scanner works smoothly and without problems, due to the speed of application, practically, the scanner does not interfere with the scanner, although the screen itself, when directly unlocked, lights up at about a hundredth of a second.
screen
In front of the front, which is equipped with a 5.5-inch diagonal screen, the ZUK Z2 has a 5-inch display based on an LTPS matrix with FullHD resolution. Other characteristics have also become simpler: the contrast is up to 1000: 1, the color coverage is up to 70% of the NTSC field.
The specification states that the maximum brightness is 400 cd/m2; in practice, the brightness of the screen creates darkness. As a matter of fact, the touch screen can receive no more than 5 touches per hour. To be fair, it should be noted that this does not affect everyday use.
Hardware platform and productivity
Apparently, the main feature of the ZUK Z2 lies in the fact that it is one of the most inexpensive smartphones on the Snapdragon 820, which operates at a nominal frequency of 2.15 GHz; moreover, the updated firmware has added an overclocking mode to which processor frequency and increases to 2, 3 GHz. It’s incredible, but a fact: in overclocking mode, the smartphone scores less points in synthetic tests than in normal mode. Another important feature of the ZUK Z2 is that the body is built to get very hot in any way you want in the world, and especially in my memory the device at 820 “Snap”, which is similar to this ї problems.
RAM type LPDDR 4 - 4 GB. The permanent memory is 64 GB, and it also complies with the eMMC 5.1 standard, which is significantly higher than UFS 2.0, installed in most smartphones with Snapdragon 820 on board. Who has a great marketing trick: take care of yourself inexpensive smartphone on a top-end chip, but with plenty of memory. This fact is recognized in no way without affecting the daily consistency and smoothness of the interface. The difference begins to be noted when you launch important add-ons and games.
Steel bond and interfaces
The smartphone has two equal slots for nano SIM cards and one radio module. A set of supported LTE frequencies, which includes Smug 3 and 7, will allow you to connect to most households in Russia.
dial dartless interfaces There is no dual-band Wi-Fi ac and Bluetooth 4.1, no NFC, no IR port. Wired interface supports USB standard 2.0, and the rose is type C.
Battery and autonomy
ZUK Z2 installations have a battery with a capacity of 3500 mA ⋅ year, which can be fully charged with a complete life adapter with an output charge of 2.5 A for 2 years and 10 costs (from 0% to 75% for 70 costs).
The presence of a non-colorful 5-inch screen and a large battery were beneficial to the autonomy of the device. In mixed modes of operation with serious demands, the ZUK Z2 is guaranteed to last until late evening with 6-7 years of screen time. Testing in standard modes also showed superior results.
Note. Testing is carried out in the following modes using the following method: - listening to music in headphones at maximum volume with the screen turned off; - viewing 1080p video from the memory of the device at 50% brightness and maximum volume of sound in headphones; - active browsing (constantly opening new tabs, actively scrolling pages, etc.) via Wi-Fi at 50% brightness; - 3D games (Real Racing 3) at 50% brightness.
Cameras, photos and videos
The main camera of the smartphone includes a 13-megapixel ISOCELL sensor, covered with a 5-component lens with an F2.2 aperture and an equivalent focal length of approximately 24 mm. Digital stabilization and hybrid autofocus.
IN system camera There is no manual mode, the program has scanty functionality, but narazi Does not cause focus/exposure locking.
In a well-lit environment, the ZUK Z2 camera is capable of producing sharp photographs with correct color reproduction and a medium dynamic range. On some photographs, you can mark the program to increase sharpness, but it won’t catch your eye. Clickable! Photos from ZUK Z2, right-handed -:

The panoramic shooting mode in the ZUK Z2 is implemented seamlessly. The photo taken in a bag has 48 megapixels, the capture process is not complicated, seams and gluing artifacts are not visible on the photo, and the sharpness has been increased in line with the Z1. You can only rely on the low speed of storing the image, the camera must be moved very far, through which objects can be confused. Clickable!

The video of the smartphone is recorded with a maximum resolution of 3840 * 2160 pixels at 30 fps and with dual-channel audio. Є quadruple shooting mode in HD resolution at 30 fps and without sound. The system camera has three options for high-speed capture: from stored images at speeds of 120 fps, 240 fps and speeds of 960 fps. In fact, in all three options, the video will be played at a speed of 120 fps, and if you open the file in any third-party player, the video will be played at several levels. The previous player can upscale the video by 4, 8 and 32 times, probably with the help of frame interpolation.
sweetness to sound
On the body of the smartphone, there is one loudspeaker, which is quite bad: there is a reserve in volume, the tonal balance is equal.
The sound in the headphones is just as bad. True, a smartphone has practically no reserve in terms of thickness, which is undesirable and extremely unacceptable. ZUK Z2 is the first smartphone on the Snapdragon 820 to have such a shortcoming. The system has daily sound modifiers and no FM radio.
