▲ Write in front

With the domestic mobile phone manufacturers catching up with each other in the launch of new products, the Snapdragon 820 has gradually been applied to each flagship machine. Just as Chang Cheng, CEO of Zuk, once said, "It's not the 820 flagship machine, it's all bragging." Today we finally have a chance to get it Love to play computer games What will be the performance of the ZUK Z2 small screen flagship phone with Snapdragon 820+4G memory+64G flash memory? Let's have a feel.

▲ Unpacking and appearance

The ZUK Z2 mobile phone has two classic colors, black and white. The mobile phone I got is white, which is my favorite color. The package of this white ZUK Z2 is very simple and clean. Apart from the appearance of the mobile phone, there are only "All Netcom 4G+", "ZUK Z2", "Lenovo" and other logos on the package.

Open the packaging box. Except for the mobile phone ZUK Z2, only the charger and the data charging cable are available as accessories, plus simple instructions.

Let's take a look at the only accessory data charging cable and charger. The ZUK Z2 data charging cable uses a USB Type-C interface, which supports USB 3.0 high-speed data transmission in addition to charging.

The charger output of the ZUK Z2 is 5.3V 2.5A. From the current of the original mobile phone charger commonly used in the market, the iPhone's current is 1.5A, Huawei's current is 2.0A, and the 5.3V 2.5A of the ZUK Z2 is a large current output. Therefore, the original charger should be used as far as possible to charge the ZUK Z2 in order to prevent the use of other brands of chargers to charge the ZUK Z2. At the same time, try not to use the charging head of ZUK Z2 to charge other brands of mobile phones, so as to prevent excessive current from heating or damaging the mobile phones.

The card slot of ZUK Z2 is designed as a dual card, which supports the mixed insertion of the whole network, that is, it supports the mixed insertion of any two mobile phone cards in card 1 or card 2 of three major operators of China Mobile, China Unicom and China Telecom without considering compatibility.

The effect after taking out the mobile phone is white, round and elegant, and embedded with a 5.0 inch high-definition screen.

ZUK Z2 feels very comfortable in the hand. The appearance of ZUK Z2 adopts simple linear design. The double-sided 2.5D suspension glass formed by high temperature pressing can ensure the overall strength of the glass material and at the same time obtain a more delicate feel than plastic and metal shells.

The left side is an integrated structure without entity or touch button.

The back of the ZUK Z2 is also clean and simple. In addition to the camera, flash and noise reduction hole in the upper left corner, there is only the ZUK logo at the bottom.

On the right side are the volume+- and on key physical buttons and the phone card slot.

There are no buttons and openings on the top, and the relevant openings are concentrated on the bottom, such as the headphone jack MIC、 Data charging hole, external horn hole, etc.

At the lower part of the front is the U-Touch multi-function touch and press button, which can unlock the touch fingerprint, tap back, slide left and right to switch applications, click back to the desktop, double-click to enter the background applications, and some functions can be customized and can add functions such as "long press"; The lower part of the back is the ZUK logo.

It was also mentioned that ZUK Z2 is a front and back 2.5D suspension glass, so the side has been chamfered in the treatment process. It can be seen clearly from the side view in the following figure. This chamfered angle treatment not only solves the connection of 2.5D suspension glass, but also visually makes the fuselage appear thinner and more beautiful.

ZUK Z2 adopts the cameras with the first 8 million and the second 13 million HD physical pixels. The 1.34 nanometer large COMS can effectively absorb more light and image more clearly. The large aperture of f/2.2 ensures more light input to make the picture more realistic and transparent. There will be special photo sample chapters later.

▲ Comfortable and easy-to-use ZUI

Lenovo's ZUK Z2 is equipped with the in-depth customized ZUI 2.0 system based on Android 6.0. The overall visual effect of ZUI presents a small, fresh and simple style. The icons are all redrawn, and the flat style is clean and comfortable.

Weather, clock, calendar.

Set skin, about this machine, system update, etc.

In addition, ZUI 2.0 also supports personalized customization such as customized screen lock and font change. Those who like personalization can try it.

▲ Camera and sample

ZUK Z2 adopts the cameras with the first 8 million and the second 13 million HD physical pixels. The 1.34 nanometer large COMS can effectively absorb more light and image more clearly. The large aperture of f/2.2 ensures more light input, making the picture more realistic and transparent.

In terms of camera functions, ZUK Z2 adopts a simple and efficient interface, cancels the traditional complex camera menu, and uses a simple six function menu: HDR、 Scale, flash, panorama, fast action, slow action.

Let's take a look at the sample effect of the default camera. The photos are generally clear, clean and transparent.

In addition to taking photos and videos, the camera of ZUK Z2 also provides "fast action" and "slow action" effects;

"Fast action" is the time-lapse photography function we see on professional cameras. It can speed up the display of images, compress the original long time images and fully display them in a certain time, which is mostly used to show the changeable and busy scenes (as shown below);

"Slow motion", in contrast to "fast motion", is also called high-speed photography, which is used to slow down the original fast motion to see details, such as the moment when water drops splashed onto the water surface.

▲ Screen performance and visual angle

ZUK Z2 is equipped with a 5.0 inch full HD LTPS super retinal screen. The PPI is up to 441, which can achieve more accurate color restoration and almost perfect visual angle by reducing the screen pixel volume and pixel spacing. The maximum brightness of the screen is 400nit, which can easily restore the most real world outdoors.

In terms of the color restoration effect of the screen, ZUK Z2 is also very good. By comparing with other mobile phones in the market, respectively, flowers, food and portraits, ZUK Z2 is more realistic in color restoration.

In terms of gray scale test, a 16 level gray scale card is used for the test, and the transition from full black to full white is 16 levels in the middle. The ZUK Z2 screen displays the 16 levels perfectly, and the transition is clear and obvious, and the effect is excellent (due to the partial loss of camera photography, the actual screen display effect is better).

Next, continue to use five colors of red, green, blue (RGB three primary colors), gray and black to test the color restoration effect of the ZUK Z2 screen as follows, and the color is uniform.

▲ Extreme speed fingerprint identification

ZUK Z2 fingerprint unlocking adopts the built-in new pressing fingerprint module, supports high-definition fingerprint image matching technology, and has self-learning fingerprint matching algorithm. The faster the fingerprint unlocking is used, the faster the recognition rate is up to 99.7%, and the fastest is 0.1 seconds.

The following two GIF dynamic pictures of PO respectively show the fingerprint unlocking speed of the Zuk Z2 mobile phone in the black screen state and the light screen state. The fingerprint unlocking speed is very fast in both the black screen state and the light screen state.

▲ Hardware score and game experience

When it comes to mobile phone evaluation, it is always necessary to evaluate the hardware score, game fluency and mobile phone fever, which are introduced as follows:

In terms of hardware score, ZUK Z2 deserves to be the king of score. Lu Dashuai's performance evaluation score was an amazing 59458, ranking the second. It is a very excellent result that more than 1000 mobile phones can have this ranking.

Let's take a look at the experience of the game. Use the two games of Fury Flying Car and the Eye of Ashura to test. From the previous score, we can see that playing the game is not a problem at all, it is very smooth, and the light effect is realistic;

At the same time, ZUK Z2 has also done a good job in controlling the heat of the mobile phone. After playing the game for half an hour, the temperature of the north side of the mobile phone has risen from 27 degrees before playing the game to 34 degrees. Although it has risen 7 degrees, it is less than the normal temperature of the human body. At the same time, it is also affected by the temperature transmission of the human hands, so this kind of display is very good.

▲ Black technology and convenient design

1. Call card reminder during the game

You must have had such experience. When your mobile phone is playing games or chatting about videos on WeChat, a call comes in and automatically interrupts the game or video. In case of such a call at the critical moment when you are calling BOSS, you have the impulse to drop your mobile phone. Now with ZUK Z2, all this is not a problem. The calling card function of ZUI will be displayed in the form of card notification when there is a call coming in during the game. You can choose to answer, hang up or ignore the call without interrupting the game. Isn't it very considerate?

2. Application corner management

The gospel of compulsive people. The corner cue is too annoying and they don't want to pay attention to it. It's comfortable to use the application corner management of ZUI.

3. U-Touch One button Multi function

At the lower part of the front is the U-Touch multi-function touch and press button, which can unlock the touch fingerprint, tap back, slide left and right to switch applications, click back to the desktop, double-click to enter the background applications, and some functions can be customized and can add functions such as "long press";

4. Self starting management blocks family self starting

You must have this experience when using mobile phones. It is clear that applications that have not been installed will be installed quietly, and apps that have been turned off will be started quietly in the background. These are all "shameless" self starts such as application self start, family self start, stubborn self start, background wake-up, and startup self start, In addition to the self enlightenment of apps within the family system, commercial cooperation will have a more complex ecological chain, which will seriously affect the user experience.

ZUI 2.0 intercepted from the bottom of the system by creating a multi-dimensional progressive self starting management engine. ZUI 2.0 can effectively block the self starting of family applications and ecological chain applications, and block the association between SDKs to fundamentally solve the problem of association self starting.

▲ Total junction

advantage:

1. Simple, smooth and elegant appearance design.

2. The double-sided 2.5D suspension glass body has a delicate grip.

3. Three networks are all connected and double cards are inserted blindly.

4. ZUI is easy to cry.

5. The self start blocking function ensures a clean system.

Disadvantages:

The beauty function of the built-in camera is weak, only the skin grinding function, and there is no function that girls like, such as face slimming, whitening, big eyes, etc.

(The above can be solved by installing a third-party camera)
