The Nubia Z7 series is launched as a mobile phone capable of photographing Galaxy, which can be said to be the most questioned and considered smart phone at present. Of course, the nubia Z7 mini is the most popular 5-inch screen suitable for mainstream groups. It is equipped with Snapdragon 801 processor and its own powerful shooting ability. The price drops to 1499, which is quite attractive.
Nubia Z7 can be said to be a complete series. The three mobile phones with different configurations and pricing can basically cover the choices of different consumers. Of course, the most dazzling one is the most powerful nubia Z7. Although the nubia Z7 mini is inferior in hardware, it is more suitable in price and size, which is preferred by mainstream people.
Nubia Z7 mini certainly has the ability to shoot stars in the Nubia Z7 series, which will be the focus of the evaluation. The latest nubia UI V2.5 has greatly improved in all aspects of detail, and is also appropriate in terms of humanization and practicality. Of course, the dual card dual standby and 4G full Netcom can be said to be the only one in the market.
Appearance design:
Nubia Z7 mini or Nubia Z7 series still continues Nubia's own design. Users of Nubia Z5 series are also familiar with the family face with high identity. There is a 5-inch 1080P screen on the front of the nubia Z7 mini. The effect is quite good when the screen is turned off.
On the top are earphones, sensors and front camera. The sensor of nubia Z7 mini is hidden deeply due to the panel, which should be liked by friends with obsessive-compulsive disorder. The Nubia Z7 mini front camera is 5 million pixels, which is also quite good.
The bottom is a solid touch key. What I like most about Nubia UI is that it can make personalized settings for the physical touch keys. The left and right sides of the Home key are hidden, and can be set as the return key and menu key through the system, which is suitable for the use habits of different people. The bottom three entity touch keys are all backlit.
The volume key and power key on the side are in proper position, and there is no pressure when operating with one hand. The mirco USB at the bottom is not designed to be foolproof. In addition, the rounded edge design of the nubia Z7 mini is also very comfortable to hold.
The back of the nubia Z7 mini has a rear camera and speakers. Among them, the 13 million pixel rear camera is dotted with red circles, which is very eye-catching, with flash lights and mic on the left and right respectively.
The rear cover of the nubia Z7 mini is designed to be detachable. Of course, there will also be various official color covers available later. After opening the back cover, you can see the double card slot design available in the nubia Z7 series. More importantly, the Nubia Z7 series supports 4G full network communication, that is, GSM/CDMA/WCDMA/TD-SCDMA/TDD-LTE/FDD-LTE, covering the 2G/3G/4G network support of the three major operators. This is the only one in the market that is so powerful.
The three dimensions of the nubia Z7 mini are 140.9 * 69.3 * 8.2mm, and the weight is 143g. The single hand operation can cover most areas of the 5-inch screen, and there is no pressure to hold it for a long time. The edges and corners are round enough, without the feeling of top palm.
Screen effect:
Nubia Z7 mini uses a 5-inch 1080P screen from Sharp, uses Sharp's unique CGS process, and New Mode 2 full view technology. The surface uses Corning's third-generation gorilla glass. 445ppi can meet the needs of Maoists.
The actual comparison uses nubia Z5s mini, where the upper is nubia Z7 mini and the lower is nubia Z5smini. In the contrast of solid colors, it can be seen that the screen color of nubiba Z7 mini is more moderate, while nubiba Z5s mini has obvious yellowing.
(Nubia Z7 mini appears purple due to shooting, and the actual visual effect does not have this phenomenon.) Under the pure black contrast, it can be seen that nubia Z5s mini has obvious light leakage. In terms of black contrast, nubia Z7 mini and nubia Z5s mini can reach the grid 3
In terms of color transition, nubia Z7 mini also performs better.
Compared with the actual pictures, it is obvious that the color restoration of nubia Z7 mini is accurate, and the red is slightly saturated. The overall screen does not have the white feeling of nubia Z5s mini.
System UI:
The nubia Z7 mini uses its own nubia UI V2.5, which is completely new in terms of aesthetics and ease of use. The lock screen interface of nubia UI V2.5 is very beautiful. There will be a red circle at the bottom of the lock screen. When charging, there will be green diffuse light, which is very sensible. The camera can be unlocked and turned on quickly by sliding at different levels. If the function can be customized later, it will be better in personalization.
The Nubia UI V2.5 desktop is a single-layer design, which is also the design direction of mainstream ROM/OS in China at present. It is also quite easy for most domestic consumers to get started. There is no problem with common screen management and adding folders and widgets. When sorting icons, the selected icons will be placed at the bottom, which can improve the efficiency of sorting.
Nubia UI V2.5 uses half arc lines in folders and pop-up menus, which are accompanied by pop-up animations. It looks very beautiful. However, the requirements for performance and resources are really high, which needs further optimization. Of course, this disadvantage can be avoided by turning off dynamic effects in auxiliary functions.
The task manager uses a card design, and displays the corresponding remaining memory and one click cleaning. Of course, it can be closed by sliding up or added to the one click cleaning white list by sliding down. The card design is not only beautiful, but also can only see the current operation of the corresponding background program.
The drop-down bar is an interesting part of Nubia UI V2.5. Compared with the common shortcut switches located at the top, the shortcut switches of nubia UI V2.5 are located at the bottom, and the shortcut switches can be adjusted and selected. After the "View Notification Bar" function in the touch gesture is enabled, you can slide down to view the notification bar at any position on the desktop with a single finger. It is very long and can be controlled with one hand.
Nubia UI V2.5 has quite a lot of details about the screen brightness adjustment. For example, there is a fine adjustment under the automatic brightness adjustment, and with intelligent memory, it can achieve a better screen brightness experience. It also provides screen display preferences, which can adjust the saturation of the screen to suit the preferences and feelings of different people.
Of course, there is something to say about the sound. Although the nubia Z7 mini does not have an independent decoding chip of nubia Z7, it can enhance the volume and switch modes through the built-in DTS sound effect.
The personality function of Nubia UI V2.5 is quite new. First, let's talk about common touch gestures and sense of intelligence. Compared with other manufacturers, Nubia UI V2.5's touch sense is more practical, such as double clicking on the screen, viewing the notification bar, and three fingers switching applications, without all kinds of weird gestures.
Similarly, the intelligent experience of Nubia UI V2.5 is also practical. For example, somatosensory dialing, somatosensory answering and flip mute are also functions I like and have been using, which can really reduce the operation action.
When it comes to functions, it is of course the Nubia UI V2.5 profile. Literally, it is designed for different use scenarios and people. There are pocket mode, single hand mode, power saving mode, sleep mode and desktop mode. Among them, the pocket mode is the most common anti false touch and ring tone. One is to avoid disorderly operation in the pocket, and the other is to avoid missing the phone.
Of course, the power saving mode is to reduce the CPU frequency and screen brightness as much as possible to achieve the power saving effect. Of course, it is better to use Nubia electrician than this power saving mode, which we will talk about next. The sleep mode can avoid interruptions and the situation of running traffic quietly through the timing switch.
How to operate with one hand is the most frequently asked question of every mobile phone at present. The one hand mode in Nubia UI V2.5 is triggered by shaking the mobile phone, and can adjust the size of the small screen to facilitate the use of people with different hands. The trigger probability can be 100%, and the single handed flip does not need to be too large, but it will not trigger easily.
There are two desktop modes of Nubia UI V2.5. One is the common standard desktop, and the other is the easy mode. In fact, it is a mode specially designed for special people. In the easy mode, larger text and icons and simpler interface layout will be provided, which will make the phone more simple and simple to use.
Easy mode is actually a simple mode with mixed widgets such as icons. As shown in the figure, the flashlight can be switched directly. In addition, some of the built-in applications, such as SMS, contacts and phones, have been redesigned and modified in the easy mode, so that special people can use them better and more purely.
As mentioned above, Nubia UI V2.5 can customize the bottom keys separately, which is actually a question of whether the return and menu keys are on the left or right. The lock screen album is a new display effect, adding fun.
To my surprise, the split screen function that first appeared on nubia X6 also appeared on nubia Z7 mini, which really surprised me. This split screen function is to divide the screen into two parts. You can view two applications and operate them at the same time. This split screen function may be a little similar to the suspended widget, but the visual effect is better. It is quite good for people who have requirements for simultaneous operation of multiple tasks.
The use of split screen effect on the 5-inch screen of nubia Z7 mini is still limited by the small screen. I personally think it is better to use it on the 5.5 screen of nubia Z7 Max. While built-in applications such as browsers and players can be displayed perfectly without black edges, other applications such as Weibo and WeChat need to switch display through the blue dots in the figure.
Nubia UI V2.5 also has some built-in applications, such as the player manual, Nubia electrician and Nubia Niudun, which are all developed for the domestic use environment. For example, forgetting the manual is to show some hidden functions of Nubia UI V2.5, as well as complex functions through pictures and texts for better education guidance.
As an application launched for your own mobile phone, Nubia electrician has quite powerful functions, and from the name, it is mainly for battery life. The main function of Nubia electrician is application management and networking management. The application management can view the corresponding power consumption and auto start management. Network traffic can be viewed and managed accordingly.
In addition, in the setting menu, CNOOC has quite a lot of adjustment settings for power saving. Of course, it is more exaggerated to mention intelligent frequency modulation and temperature monitoring, which can adjust the frequency and view the temperature of the SoC CPU and GPU respectively.
Nubia Niudun came into being to meet the requirements of application permissions, mobile acceleration and other functions. Compared with various mobile phone butlers, those designed for their own home are undoubtedly the best choice. Nubia Niudun provides five functions, including harassment interception, traffic monitoring, phone acceleration, application management and phone retrieval, as well as popular functions, such as garbage cleaning and memory optimization. We can basically say goodbye to the phone butler.
Performance and endurance:
Nubia Z7 mini uses a better balance between processing power consumption and performance. It uses a special version of MSM8974AA with a frequency of 2GHz. It is the first smartphone to use this SoC. It should be noted that the nubia Z7 mini used in the evaluation is an engineering machine. There is still much room for optimization in software debugging. Testing only represents the level of the engineering machine.
Compared with the common 2.3GHz frequency, the MSM8974AA used by nubia Z7 mini is reduced to 2GHz, but the GPU is still 574MHz Adreno 330, which theoretically will not affect the game experience. The actual theoretical score also shows that the score of nubia Z7 mini is not too dazzling due to the problem of engineering machine, but it also shows a normal level.
In terms of actual game testing, use Wild Racing 8 for testing. During the game, the nubia Z7 mini is basically maintained at 28~30fps, with occasional frame drop. It is expected that it will perform better after subsequent optimization.
After running for 15 minutes, the maximum temperature of nubia Z7 mini is 41.6 ° C, which is at the average level of Snapdragon 801 processor. However, the highest temperature is at the battery position, and it is expected that the subsequent system optimization will have better performance.
In terms of endurance, the nubia Z7 mini battery has a capacity of 2300mAh, which is not detachable. However, through the reasonable use of the power saving mode and Nubia electrician, you can make adjustments according to your own use, so that the endurance time is well guaranteed. The actual test is to use the mobile 3G network for light daily call use, which can be charged once every three days, and can also be charged once every day under heavy use.
The biggest feature of Nubia Z7 series, or Nubia's feature, is of course All Netcom, and this time it is 4G All Netcom. The nubia Z7 series supports GSM/EDGE/CDMA/WCDMA/TD-SCDMA/FDD-LTE/TDD-LTE. To put it simply, China Mobile Unicom supports 2G/3G/4G, which is certainly no pressure to use.
Moreover, nubia Z7 series are designed with dual cards and dual standby devices. It is the first dual card selection memory function and supports 4G/3G network soft switching. Multiple cards can also be used perfectly for one machine. It should be noted that China Telecom can only use card slot 1.
Shooting ability:
In terms of hardware, the Nubia Z7 mini uses the Sony IMX214 sensor, which is highly praised. Basically, it is equipped with a very good shooting quality. The rear camera has a 13 megapixel F/2.0 aperture, and uses five independent lenses and blue glass composite IR filters.
For different users' preferences, Nubia has designed three shooting modes, namely the simple and easy to use Auto mode, the creative Fun mode and the Pro mode for professionals. Compared with the brilliant Pro mode, the Auto and Fun modes are actually more interesting and fun.
But unfortunately, the items that can be set in Auto mode are basically zero, and even the basic resolution adjustment cannot be selected as 16:9, so the flexibility is slightly average. In addition, the image resolution in Auto, Fun and Pro modes is set separately, which may bring some doubts to some users. Of course, the preview of depth of field provided in Auto mode and many modes in Fun mode are the highlights.
There are nine functional modes in Fun mode, namely, star track, nebula, light painting, super night scene, crystal, multiple exposure, passer-by removal, motion track, short video, real-time effect, panorama and interval continuous shooting. There are quite a few functions that need to be used with a tripod. Of course, the star orbit and nebula mode are also very powerful.
In contrast, the adjustable items in Pro mode can be called insanity. The common ones are image resolution, white balance ISO、 Exposure supplement and HDR, etc. More special and quite useful are polarizing filters, composition lines, manual focusing, compass level and depth of field preview.
Of course, in many adjustable modes, the Pro mode requires a high level of basic skills for users, otherwise it is not clear what the functions are used for. Interestingly, Nubia has placed a photography skill button on the shooting interface. Click it to view the corresponding shooting modes, skills and functions.
In Pro mode, there are standard, electronic aperture and slow gate. Of course, the most popular one is electronic aperture. On many mobile phones, we can see the long exposure mode, but the aperture cannot be adjusted, so it is very easy to be white after long exposure. Adjust the aperture through the electronic aperture. Nubia Z7 mini will not show overexposure of the image even if it is exposed for a long time.
Nubia Z7 mini or the whole Nubia series mobile phones can achieve white balance, focusing and light measurement independence in Pro mode, of which light measurement focusing separation is the most useful. In actual shooting, when shooting a wide range of backlight, the mobile phone can not achieve global focusing and light measurement. If it is like a common mobile phone, it will cause local overexposure or darkness.
As shown in the figure above, Nubia Z7 mini took a photo by using photometric focusing separation instead of HDR mode. It can be seen that the whole picture is more accurately exposed. Of course, this function may be slightly more demanding for ordinary users. If there is a prompt on how to select it, it will be more practical.
Nubia Z7 mini is easy to create atmosphere when taking pictures of large scenes, and the overall visual effect is quite good. With reasonable photometric focusing separation, the effect is better.
The performance of nubia Z7 mini in macro is also excellent, and through manual focusing, you can achieve more powerful macro distance.
If we say that the greatest benefit of the photometric focusing separation is, of course, the best performance scene is in the night mode. In normal mode, when shooting night scenes, local overexposure is more likely to occur. By adjusting the metering points, the overall picture is more comfortable.
Since the nubia Z7 mini used in the test is an engineering machine, it is not well optimized in software debugging, so there are many noise points at night. As shown in the figure above, the iso is 1600, but the noise is up to the performance of ordinary mobile phones at 3200. Even if the exposure is very accurate, it is still unsatisfactory. It is estimated that subsequent software optimization can have better performance.
Nubia Z7 mini is quite accurate in exposure, and has a stable and good performance both in the sunset and in the midday hot sun.
Unfortunately, due to the typhoon, the clouds are thick, The orbit and nebula model of nubia Z7 mini cannot be shown to you for the moment. In addition, Nubia Z7 mini's powerful photography ability and rich shooting modes can only be seen in a short time. We will conduct a detailed evaluation of Nubia Z7 mini shooting in the future. Please wait. Of course, it can be concluded here that Nubia Z7 mini has a very strong photographic ability.
The Nubia Z7 mini front camera is 5 million pixels, which has certain advantages over the common 2 million pixels. However, the software is a little general. There is only one beauty effect, and it is only controlled by the switch, rather than the level adjustment. After taking the selfie, the sister said that whether the effect of opening the beauty food was too obvious, quite unnatural, and probably because of the system software, it also seemed red overall.
Summary:
From the perspective of appearance design, Nubia Z5 series and Nubia Z7 series have not changed much. The design of maintaining the family face is standard. The 5-inch screen of the nubia Z7 mini has a very good circumference and weight, and the smooth transition of the edge makes the whole grip and feel very good.
In terms of its shooting ability, Nubia Z7 mini's IMX214 sensor and 13 million pixel F/2.0 aperture are the only ones at the same price. The newly upgraded NeoVision 4.0 equipped with a bracket, many shooting modes, focusing and metering separation, and the first electronic aperture, polarizing filter functions, all undoubtedly make the whole shooting process much more comfortable.
In terms of performance, nubia Z7 mini can be said to be the first time to achieve the price of 1500 yuan for Snapdragon 801 smartphone. The 2GHz MSM8974AA processor, 2G RAM and the redesigned and upgraded nubia UI V2.5 have great advantages in overall smoothness and humanization at the same level.
