In recent years, Lenovo's business in smart phones has been tepid. Huawei is the only company that used to be cool in China. Perhaps in order to change this situation, Lenovo has reintroduced the Zuk series mobile phones released by Magic Workshop into its portfolio, and released the Zuk Z2 series mobile phones last May. The standard version of the Z2 is equipped with a full blooded version of Snapdragon 820, 4G+64G large memory, The 5-inch screen is a little higher than the Xiaomi 5 in configuration, and the price is still 200 yuan cheaper. Now the price of the high configuration Xiaomi 5 (3G+64G) is 1799 yuan, but the lowest price of the zuk z2 is only 1399 yuan, and the gap is growing. In order to expand sales, Zuk also launched a low configuration version of 3G+32G, which is 1199 yuan, and even dropped to 1099 yuan in the event. Use the price of the mid-range model to experience the Snapdragon 820 CPU, Only ZUK can do it. How about this model? Why does it still fail to open a market for ZUK after falling again and again? Let's discuss this Zuk Z2.

Appearance display

What I started with was a white standard version of the ZUK Z2. In fact, the packaging style of this phone is very ordinary. Apart from the word "flagship" printed on the front of this phone, the packaging style of the flagship model is completely invisible. Therefore, the zuk z2 has become a mid range model in terms of packaging.

The cover of Zuk z2 is a half section type. The biggest advantage of this kind of packaging is that the cover is easy to open. Instead of the whole cover, the box cover is opened by throwing.

The accessories of ZUK z2 include thimble, charger and charging cable, as well as a mobile phone.

Its charger has an output power of 5.3V-2.5A and supports fast charging. The cell phone uses a battery of 3500mAh. The official once said that 80% of the battery will be charged in one hour. We will test the actual charging speed later.

The design style of the ZUK Z2 mobile phone is square, the arc at the four corners is also small, the black edges around the screen are acceptable, the resolution of the screen is 1080P, and the PPI is up to 441. It is said that the front of the phone is coated with an anti oil stain coating, and the effect is unknown, because a frosted film is presented when it leaves the factory.

However, the quality of this film is really not flattering. It has not been pasted well. There are many bubbles. The design of the ZUK Z2 in the parallel is very special. It integrates the sensor and the earpiece together, leaving a black dot on the top. The front 8 megapixel camera has a COMS of 1.4 μ m. It can provide better shooting effect.

The front fingerprint identifier does not use the round waist key, which is common in the market, but a rounded rectangle, which also conforms to the overall square design style of the phone. This key integrates a variety of functions. In addition to tapping back and pressing home, it also supports double clicking to open the background. Sliding left and right can switch background applications. In the settings, you can adjust the functions according to your own habits, For example, I adjusted it to long press to open the background, and double click to turn off the screen.

The back material is still 2.5D glass, so this is a dual 2.5D glass phone.

I don't know why. The camera of the glass back cover mobile phones of domestic manufacturers likes to be placed in the upper left corner, as is the case with the ZUK Z2. The pixel of the rear camera is 13 million, and Samsung 1.34 is used μ I have experienced this CMOS chip on Q5 plus of 360 mobile phone, and I particularly like the effect of the shot; As the flagship model, the flash is monochromatic and warm, which makes me somewhat surprised; The hole next to the flash is a noise reducing microphone.

What I can't understand most is the middle frame. It is made of plastic material. In order to insert a 3500mAh battery, the thickness of the body is a little thick. Although there are chamfers on both sides, the overall effect is not good. In addition, it also places the power key, volume key and SIM card slot on the right side of the frame. The common style is to place the SIM card slot on the left side of the frame.

This SIM card slot supports dual cards and dual standby, but does not support TF card expansion. Not giving TF card slot is a common means for flagship phones. Card 1 and card 2 are not marked on the SIM card slot. Card 1 is inside and card 2 is outside.

Headphones, microphones, power connectors and speakers are on the bottom, and ZUK Z2 uses the Tpye-C connector.

Let's compare another 5-inch double-sided 2.5D glass phone. Throw away the brand logo, and from the back, we can't see much difference.

But the plastic middle frame is different from the metal middle frame immediately.

I tried it. I used the official publicity map to make a picture of ZUK Z2 in a metal frame. Although the level of PS is not very good, it can be seen that the quality of the phone has improved.

Desktop experience

This mobile phone does not use Lenovo's mobile phone operating system, but the ZUI system developed by Magic Workshop. At present, the system has been upgraded to the bottom layer of Android 7.0. At the beginning of the release of ZUI, there was such a feature on the lock screen that the lock screen wallpaper only displayed a square area on the upper half of the screen, and the other parts were filled with the background color of the gauss blurred version of the wallpaper. Its purpose was to make the wallpaper display without any obstruction. In fact, there was no technical content in this game, just a simple code, This screen locking effect can be achieved in other mobile phone systems that support screen locking customization (such as MIUI and YunOS).

Its shortcut toolbar is not integrated in the drop-down notification list, but is retrieved from the bottom of the screen. The system desktop of ZUI is very simple, but the introduction is a bit excessive. There is almost nothing except the system functions, not even a video player. The default desktop icon is still the same style as it was released the year before last, and it has not changed. The two small blinking eyes on the message need to be displayed when there is an unanswered message. In addition, I really don't know what the trigger condition is for the small plane that skips on the weather.

In terms of theme, there is a big background like Lenovo. It took two years for ZUI to make a theme center, and the four built-in themes were added last year. I don't know how users of ZUI survived. Maybe they are masters who don't like changing themes~

System experience

My experience of fingerprint identification of ZUK Z2 is good, and it supports WeChat and Alipay fingerprint payment, which is particularly convenient to use.

The application center of ZUI uses the application center of its father Lenovo, which may be the only Lenovo element in ZUI. The most beautiful calendar advertised at the beginning of the release, to be honest, is quite common, that is, 12 vector pictures drawn by month are added to the calendar interface, and the calendar is really a calendar, without any additional functions. The painting style of Weather App is a bit out of place with the whole small and fresh system. I think we should use a dynamic vector style background, and the painting style will be unified.

The security center of ZUI looks a little simple. The home page only has the cleaning and acceleration functions. When you enter the security center with more than 80% of the memory occupied, it will directly give you a one button acceleration button. However, the physical examination is not good because there is no animation effect. After you click the acceleration, the system will be stuck until the acceleration is completed.

The basic functions of the security center still exist. It needs to slide out of the interface to the left. It has anti-virus, acceleration, cleaning, traffic monitoring, permission management, harassment interception and other functions, but it lacks payment protection functions. As mobile payment is becoming more and more important today, payment protection is very important. The pseudo base station interception in the publicity is not reflected in the security center, and I cannot find a pseudo base station to try.

Before the release of the latest Android 7.0 underlying version, the functions of the entire ZUI system were too basic and there was nothing special. The latest system added some small functions. Although there were not many functions, they were better than nothing. Let's experience them! The location traversal function should be a function added in the previous version. This function is actually a function of forging GPS coordinates to cheat the App's positioning function.

I have experienced this function in the other two systems, but Lenovo's location traversal is the most simple and crude. Other systems help you collect ready GPS information, and do not allow you to make up GPS locations at will. In addition, you can only use this function for several fixed social software, while Lenovo's position traversal function allows you to choose your own location at will, It can be used for any application. I really want to try this function to play the game "Pet Fairy go". Where can I download this game?

The screen recording and split screen functions are added in the latest version. The start button of the screen recording is in the list of all functions in the shortcut menu. After use, the recording time will be displayed at the top. This effect will not be recorded into the video. Clicking it will close the recording. There is no pause function. If you play the game horizontally, the screen recording information will not be displayed.

After the split screen function is enabled, there will be a "Lv" icon on the application in the background interface. Click it to use this application for split screen operation.

WeChat chat/article interface quick switch function, which I think is a very practical function, I think everyone has such trouble, when reading an article suddenly came a very important message, do you read it or not? After reading the information, the article can't go back. We have to search again. ZUI finally helps us solve this problem. After reading the information, you can go back to the article you just read from the prompt bar above.

WeChat red packet is the final function of the system. I don't know whether this function is against the requirements of WeChat for red packet software. When you turn on the U-touch fingerprint red packet function, when there is a red packet reminder, as long as you put your finger on the fingerprint identifier, you can directly unlock it and automatically enter WeChat. It is very practical to automatically complete red packet robbing, As long as we are not blocked by WeChat

Sports experience

The sport module has been added to the ZUK Z2 series of mobile phones to achieve more accurate step recording function, but you should always carry your mobile phone with you~

The ZUK Z2 Pro mobile phone has also added heart rate, blood oxygen and ultraviolet sensors, and these sensors have been castrated on Z2. Z2 can only use the camera to test heart rate. As for accuracy, it is not necessary to take it too seriously

Running experience

I used Master Lu to score 140692 points. It seems that I didn't know Master Lu before? The former Master Lu should not have such a high score, it should be revised; The experience score is 107.53, which is not bad. The actual experience is really smooth. The html5 score is 41055, which is in line with the rules. It seems that Master Lu likes to change the score. I remember that my desktop computer was not updated once a few years ago, and the score would be higher... It is not a version of the score, and has no comparative value at all

The score of Anthare is 138644, which is the normal level of Snapdragon 820 mobile phones; It can be seen from the information that the mobile phone's motion sensor is quite comprehensive, but the screen only supports 5 points of touch, which makes me a little surprised, because it is usually 10 points of touch? Although 5 touch is enough.

After experiencing a game, the frame rate can still be maintained at around 30 when three soldiers refresh at the same time even when they hit the opponent's hometown. It's still nice to play the game with Snapdragon 820.

The ZUK Z2 supports fast charging, but its charging style is stable and heavy. Before 80% of the electricity was charged, 6% of the electricity was charged every 5 minutes on average. Officially, 80% of the electricity was charged every hour. My actual measurement is 73%. My use environment is certainly not as good as the laboratory environment, and the slow speed is not too much. It is still qualified. After 80%, the charging speed slowed down, and the remaining 23% took 1 hour and 20 minutes to be fully charged.

The power consumption performance is excellent. The power consumption is 2% for standby for 8 hours, 2% for listening to music for one hour when the screen is turned off, 8% for reading headlines for one hour (brightness automatic), 15% for playing games for one hour (brightness automatic), and 10% for watching videos for one hour (brightness automatic). It can be seen that this 3500 mAh battery powered 5-inch mobile phone is more than enough.

photograph

The camera is the core part of smart phones. Everyone hopes that their mobile phones can take single shot photos at their fingertips. In addition to excellent CMOS, a good photo is also very important for the focus module group and app algorithm. It is said that Apple's photo camera team has 800 people, which is an extraordinary exaggeration. The ZUI camera is really not like the flagship machine, and its functions are boring to the point of outrage. Except for fast and slow actions that I am not interested in even trying, only HDR and panorama are available. The special effects function is hidden above the black block at the bottom, and the menu will be displayed only when the fingers slide in this area.

The panoramic mode, which is almost the only function, can only take 180 ° panoramic photos. Compared with the current 270 °, 360 °, or even 400 ° panoramic photos, the panoramic view of ZUI is not good enough. The Snapdragon 820 CPU has the ability to splice 400 ° panoramic photos. Even the P10 of MediaTek can splice 270 ° photos, and only the lower level MTK6750, It can only spell 180 ° panorama.

The beauty mode is a joke. It can only be used by the front camera. The beauty mode can distinguish men and women to provide different beauty styles, but it cannot adjust the beauty intensity. The beauty style of male users is waxy yellow, while that of female users is rose red. It is not beautiful anyway, especially the beauty effect of male users is bad next door.

In the latest version, ZUI finally added professional mode, but this professional mode can only adjust four common parameters, namely ISO, white balance, shutter speed and focusing distance. The exposure compensation, saturation, contrast and other parameters cannot be adjusted. The professional mode operation interface provides a preview of the shutter speed effect. In the professional mode of the general mobile phone system, the impact of the shutter speed on the image can not be seen during the preview, but ZUI has done so. In addition to making people feel that the photo taking interface is particularly stuck, the practical value is not great.

The imaging effect in the daytime is not outstanding, but ordinary. Even in cloudy days, the imaging noise is a little bit more, and the effect is better in sunny days. But it is generally felt that the focus is not too accurate, the background is not too blurred, the CMOS should be OK, and the algorithm and focus mode set should not match well. Color restoration is quite accurate.

I guess the effect will not be better when there is a sun, but the result is not. When the light is sufficient, photography is not as good as cloudy days. The brightness of the whole picture is too high, and the shadow part, as well as noise points, the picture is not clean enough, which shows that Zuk's photography has not been adjusted at all. It may be that the original camera has changed the interface, and when you zoom in, the picture quality of the four corners drops significantly, The obvious purple edge phenomenon appears on some edge parts, which also indicates that the glass part of the focusing mode set used in the focusing mode set is not able to control the dispersion. Therefore, the focusing mode set is too cheap, and it is also one of the culprits of the poor photographic effect.

The effect of HDR mode is quite outstanding. The contrast effect is particularly obvious. The original dark picture becomes bright. The edge is a little white, the best effect can be reduced a little.

When the night just came, the effect of taking pictures was not very good, but at least it could be used.

Take it again in the dead of night. The noise and focus are very moving. The effect is really poor.

summary

As the cheapest Snapdragon 820 mobile phone, the sales volume of the ZUK Z2 is really not good, which is inseparable from the bad experience. Isn't the magic workshop focused on software development? This software is a bit of a flop. I think it can be saved by changing these problems.

1. Pack the snacks and design them well.

2. Double sided glass must be matched with metal middle frame, otherwise it is too cheap.

3. The weather interface was changed to enhance the overall coordination of the system and increase the theme center.

4. The system security needs to be improved, not to mention property security. You don't even have the most basic function of mobile phone retrieval. If you lose your mobile phone, you don't need to think about how to retrieve it. If you buy it again, please go to the Flyme Forum to see various mobile phone retrieval cases!

5. To compete for system functionality, which mobile phone can not be used separately? Double WeChat, parallel space, privacy mode, children mode, driving mode, you have a lot of functions.

6. To enhance the playability of photography, learn from Nubia, Huawei, 360, and even Meizu's cameras, which are more playable than yours. The key is to improve the algorithms such as photography and focusing. In addition, the focusing module group needs to spend some money. As we all know, it is not easy to take good photos with SLR sleeves. Especially for beginners, if they want to take good photos, they need to buy new lenses.

Of course, although I have listed so many shortcomings, the ZUK Z2 still has its advantages. It does not like tossing about, has no requirements for taking photos, and only likes simplicity. This mobile phone is worth recommending. After all, the cheapest price is to experience excellent CPU, the system has no advertising, and it is clean and light on the whole. The large battery and low power consumption are enough for users to use.
