After the Great Wall released the vivo X20 in September last year, Vivo's research and development in mobile phone technology broke out like a hang-open. First came the world's first screen fingerprinting mobile phone, and then displayed the APEX concept machine on the NWC2018, lifted hidden camera, Really full screen, dual-screen fingerprint recognition, Super HDR, etc.. It can be said that 2018 has been open since the beginning, Vivo has been feeling angry, but until today vivo X21 release, all this is considered a fruition.  Compared to the vivo X20, the advancement of the vivo X21 can be described as subversive. From the new 19:9 full screen to the double-sided glass body, as well as native adaptive screen fingerprinting and the Jovi AI artificial intelligence system. Coming soon, Vivo's new understanding of smart phones for a period of time, all these people have brought a new experience to vivo X21. 
▲ vivo X2190.3% screen share + 3D glass body Vivo X21 uses a 19:9 OLED screen, the size also increased to 6.28 inches, with a resolution of 2280×1080. In addition to the reserved earpiece, the position of the front camera, the screen covers an area of 90.3% of the front of the phone. Liu Haiping's design, in addition to vivo APEX concept machine, does not hide the front camera and handset to obtain a larger display area program. 
▲Vivo X21 The benefits of Liu Haiping's design are still very obvious. Compared with the vivo X20, although the vivo X21 screen has been increased, the height and width have been reduced. In addition to the space on the top of the X21 screen, the chin space is further compressed. , Which has a quite full impact screen effect. 
▲ vivo X21 (left), vivo X20 (right) In addition to the screen, the body material of the vivo X21 also changed from the X20 integrated metal to the double glass + metal middle frame. The back uses a 3D glass, with low arcs on both sides of the middle, more closely fitting to the grip of the palm. Feel. 
▲ vivo X21 Although not a metal material, vivo X21's body texture does not suffer. Under the glass back cover The use of the coating + silk screen color processing technology, can reflect the unique gloss. See more sandblasted metal body, vivo X21 glass material even more amazing feeling. 
▲ vivo X21 Of course, the glass body also brings the trouble of fingerprint collection, so the vivo X21 also processes the oleophobic coating of the glass. Although it still has some fingerprint marks, it can be wiped clean with the palm of your hand. 
▲ Vivo X21 Because of the internal structure adjustment, vivo X21's SIM card slot is placed on the chin. And I must mention is the vivo X21 moderate thickness and weight, which benefits from the control of the thickness of the back cover, and many glass body phone This is often overlooked. 
▲Vivo X21In addition to the appearance is not the same Apart from the fact that the screen is more open than the higher field of vision, Vivo X21 OLED screen also used P3 color management technology (DCI-P3), the advantage is a wider color gamut, the display color is more true and full, this contrast with the old model can be seen immediately difference.

▲Vivo X21 (left), vivo X20 (right) The increase in the display ratio (19:9) also allows the vivo X21 to display more content. Of course, this is also related to the adaptation of the APP to the new ratio. We will chat with you in detail on the adaptation issue. 
▲Vivo X21 (left), vivo X20 (right) In terms of watching movies, the current full-screen mobile phones are relatively obscure. Because most of the mainstream movie formats are 1920×1080, and 2.35:1 ultra-wide movie resources are similar to the wide screen of movie theaters. However, neither vivo X21 nor vivo X20 , You can set the stretch cropping mode when viewing a local movie, to force the local movie to force full-screen viewing, so as to achieve a better vision. 
▲Vivo X21 (Up), vivo X20 (Bottom) Vivo X21 uses a new 19:9 screen. The adaptation of APP is naturally imminent. It is reported that most mainstream APPs have been adapted. I believe this adaptation will be more comprehensive after the launch. Xiaobian also looks forward to watching movies online. You can also enjoy super-widescreen fun. 
▲Vivo X21 (Up), vivo X20 (Bottom) How is the game? The king of the installed machine glory seems to be no problem, and can see that targeted optimization. The first is to select the hero interface, the U-shaped groove of the bang position does not cover the hero rotten, the entire picture is Become wider, you can see more background details. 
▲Vivo X21 (Up), vivo X20 (Bottom) Into the actual game interface, you can see vivo X21 game map one more than the X20, that is to use vivo X21 can quickly find the ambush of the enemy. So for fairness, Tencent has added a translucent on both sides of the screen Dark curtain.

Full-featured screen fingerprinting
In the era of full screen, where fingerprint recognition is plagued by designers of many mobile phone brands, let's put the front, the fingerprint button is very thin, and the experience is not good. Put it behind, it seems to be a bit back to the past. At present, as the exclusive mobile phone brand with screen fingerprint recognition technology, fingerprint unlocking on the screen can be said to be a signboard experience for vivo. Although it has been felt on the vivo X20Plus before, the unlocking of the vivo X21 screen is still amazing. 
▲vivo X21 screen fingerprint identification position is still fixed The screen fingerprint adopts photoelectric reflection technology. When the finger touches the screen, the light emitted from the OLED screen penetrates the cover plate to illuminate the fingerprint texture, and the fingerprint reflected light penetrates the screen to reach the sensor, and finally forms a fingerprint image for identification. Vivo X21 screen fingerprint can be used in Alipay, WeChat. 
▲ The screen fingerprint not only solves the problem that the full screen and fingerprint recognition cannot be compatible, but also makes the mobile phone more technologically aware. Different from the common capacitive fingerprint recognition module, vivo X21 screen fingerprinting needs a little pressure. In addition, vivo X21 with screen fingerprint version is pre-applied with a special custom film to prevent screen scratching without affecting recognition. Speaking of unlocking, vivo X21 continues to support human face Identified and upgraded for this function. Only 128 from the X20 series Feature points , Upgrading to 1024 feature points that can automatically monitor faces. In simple terms, the face recognition function of vivo X21 is faster and more accurate. In fact vivo X21 can make screen fingerprints and face recognition work at the same time, further convenience Promote. 
▲Photos, mobile phones, Faces on books cannot enter face data
According to official data, the vivo X21 has added an infrared light to fill the face with infrared light at night. Even if there is no light, it can use face recognition to unlock the mobile phone. Xiao Bian also specifically tested it, after entering face information in advance, Turn off the lights in the room at night. At this time, unlock the face and you will see a red dot blinking at the top of the screen. With the support of this infrared light, the vivo X21 can be unlocked without external light, and the speed and normal light There is no difference.  Let's take a look at the changes in the system. From intelligent engine to artificial intelligence assistant
From vivo X21, vivo Funtouch OS (4.0) officially entered the era of Android Oreo, from UI interface to interaction has a completely different change. And the most intuitive experience is that vivo X21 is more smooth operation than vivo X20, it seems Based on the new system makes vivo X21 more efficient. 
▲ Funtouch OS 4.0 based on Android 8.1 Vivo X21 uses a more rounded and sophisticated icon, and the pattern on the system icon is also optimized in a more artistic and abstract direction. Make the interface look more refreshing. 
▲Vivo X21 (left), vivo X20 (right) For the chin to become more slender Vivo X21, gesture operation has completely replaced the key operation. Of course, the user can still call the virtual keys, but completely hidden button gestures will not waste such a high screen share. 
▲Vivo X21 Vivo X21 built-in The Qualcomm Snapdragon multi-core neural network acceleration chip 660AIE, which is based on the Snapdragon 660, joins the new CPU of the AIE artificial intelligence chip. It can integrate all available hardware resources into the artificial neural complex neural operations. The CPU performs calculations, and the independent AI chip is more efficient. It includes systems, photographs, games, and many other aspects. The vivo X21 performs AI artificial intelligence optimization. 
▲Vivo X21 Compared to previous wisdom engine, brand new Jovi AI engine, able to According to the user's usage and operating habits, it intelligently predicts and recognizes different usage scenarios, realizes intelligent retrieval, and smoothly switches in the background, greatly improving game performance. Jovi Artificial intelligence assistants can aggregate the important information content on the mobile phone and send out reminders to users according to different scenarios. The reminder information can be unified in one place for viewing. It is efficient and convenient. 
▲ vivo X21 Vivo X21 has 6GB of memory, so the game mode is not only optimized for the game environment, but also increased Common games can always be resident in the background for a second-second strategy. In addition to the competitive mode, the CPU and running content can be adjusted to the optimal state. According to the needs of the game, the memory space can be reasonably optimized to achieve a better gaming experience. Meanwhile, the game is Inadvertent touch function avoids the inconvenience caused by inadvertent touch in the horizontal screen game. 
▲Vivo X21 The current competitive model has already supported the glory of the king. I believe that more games will be added later. 
▲Vivo X21 According to official data, Vivo X21 will also join AI beauty, AI scene cameras, smart screens and other artificial intelligence applications, and even smart car interaction Driving mode, and automatically marking the parking position after parking, and providing the experience of finding the location of the car. This series of applications will be launched before the launch of the new machine, so we can share with you again.
A more fun backlit camera In the previous media open day, Vivian has demonstrated the latest Super HDR technology, capable of taking suitable portrait photos under extreme backlight conditions. Although it is not yet available on the vivo X21, it is believed that it won Less inspiration. In the past, the backlighting camera + intellectual beauty, vivo X21 upgrade to backlight beauty + Jovi beauty. 
▲vivo X21 (left) The camera interface is slightly changed, it is added to the AR, and the professional mode is moved to the shortcut bar.
▲Vivo X21 (left) Filters are streamlined , and uses a new filter with more prominent effects Regardless of whether it is a self-portrait or a photo shoot, the backlighting beauty is a further upgrade of the intellectual beauty technology, image magic cube technology, customer service self-timer face black under the backlight, the background is too bright, while improving the beauty according to the new and improved dual-core pixel sensor. Yan effect. And Jovi AI is based on the user's gender, skin, skin color and scene lighting, intelligent matching beauty program, so that the beauty of the more natural. 
▲ Turn on and off the backlight mode, the effect is very different Let's take a look at the effect of the real shot proofs. Compared to the X20, the vivo X21 will take a look at the skin color and temperament of the face when the portrait photos are taken. The main backlighting beauty can be both outdoor and indoor. It is a good complement to the human face. In addition, we can pay attention to the beauty pictures of men and women in the same box. We will find that the beauty of boys and girls is not the same. Boys will keep the sun a little bit of color, while girls will be partial Tenderer, you can see Jovi's beauty on the good handling of different genders. 
▲Outdoor Daylight: Portrait Mode (Blurry) + Beauty mode
▲ outdoor backlight: backlight mode + beauty mode 
▲ Indoor soft light: portrait mode (blur) + beauty mode
▲ Indoor backlight: backlight mode + beauty mode 
▲ Indoor Low Light: Beauty Mode + Portrait Mode (Blurry) 
▲Indoor low light self-timer: Beauty mode
▲Outdoor daylight self-timer: Beauty mode So what about the basic picture quality? Vivo X21 continues to use 2x 12 million pixels (24 million photosensitive cells) dual camera, support for full-pixel dual-core focus and 24 million pixel camera mode. The difference is that the vivo X21 camera is used P3 color gamut solution (wide color gamut), can bring more vivid colors, vivid photos. 
▲ Two generations of product imaging color contrast From the real shot experience point of view, vivo X21's color performance is more intense, there is a more beautiful feeling, this is very suitable for travel scenery or shooting food partners. However, Xiaobian also found that vivo X21 in some high saturation In the scene, there is a situation of color overflow, and it is expected that improvement can be made in the later optimization.

▲ vivo X21 Meng proofs It is reported that vivo X21 will also join the AI scene camera function, except It can identify scenes such as night scenes, sports, shaking and backlighting, and can more accurately identify the contents of photos, such as 'Portrait', 'Gourmet', 'Flowers' etc. 14 scenes. The AI self-portrait lighting effect can now be used in photo albums. I believe the vivo X21's camera will become more and more interesting in the upgrade.
Game performance and life As mentioned earlier, the vivo X21 equipped with Qualcomm Snapdragon multi-core neural network acceleration chip SDM660 AIE, in addition to strong artificial intelligence computing capabilities, its own performance is also quite strong. And vivo X21 memory and storage were upgraded to 6GB and 128GB, respectively Large memory naturally means smoother speeds. Due to increased memory, vivo X21 can also be targeted Common games allow resident backgrounds, thereby increasing the opening and switching speeds of large games such as King Glory. 
▲ vivo X21 security bunny rabbit run points Because Gamebench can not record, so here in a different environment for visual inspection. The king of glory for example, in the actual game operation, vivo X21 frame rate range between 45-60Fps, most of the time stable at 55Fps, About 45 Fps or so when the group fights skills, there is no Caton situation. 
▲ vivo X21 has been adapted to the king's glory high frame rate mode
▲19:9 screen sees more map content than others The vivo X21 has a built-in 3200mAh battery, which is a little bit less than the 3245mAh X20. The difference in the actual experience life is not obvious. Also taking King Glory as an example, to open the special effects high frame rate mode and open the game mode, The 15-minute slowdown consumes about 6%. Xiaobian made about 21% of the power consumption in about three hours in one hour. The battery life is still satisfactory when the load is fully on.

Edit Comment
Vivo X21 has a screen fingerprint version and a non-screen fingerprint version. If you consider from the perspective of Xiao Bian, it is natural that the former experience is the most full and most worthwhile to purchase. After all, at the present stage, only vivo phones have screen fingerprint technology. Vivo X21 not only brings a strong sense of the future, but the key is that uniqueness allows you to win in the circle of friends in the starting line. 
▲ vivo X21 With the 19:9 Liu Haiping and 3D double-glazed glass designs, the vivo X21 has taken a step further on the previous generation of products in terms of visual experience and appearance. Especially in today's metal fatigue, the return of the two-sided Glass design, and even people have a stunning feeling. 
▲ vivo X21 In addition to the external changes, Vivo X21 actively supports AI artificial intelligence, and The multi-core neural network acceleration chip 660AIE enhances system performance with more intelligent resource scheduling. These optimizations are more automatic in the background and do not require user intervention. According to the user's habits, vivo X21 will play games, read, Take photos in different directions. With the addition of more AI features, the experience of vivo X21 will become more full. It can be said that vivo X21 is a solid basis for the future AI artificial intelligent mobile phone system.
▲ vivo X21 The disadvantage is that the vivo X21 adopts the 19:9 screen to adapt the progress of software adaptation. A bit sluggish, a variety of mainstream software has yet to be updated to adapt to the new ratio of the screen. However, this problem is not only encountered vivo, Apple's iPhone X also issued a compulsory adaptation notice. Of course, a broader display The effect is the user's pursuit and enjoyment, I believe that the major mainstream APP will soon fully adapt to the new ratio of 19:9, after all, this is the next mainstream full screen display ratio. Vivo X21 will be divided into standard version and screen fingerprint version, priced at 3198 yuan and 3598 yuan, will be on sale on the 24th and 28th.
