[IT168 evaluation] If anyone asks, what are the hot-selling technology keywords for smart phones nowadays, we are sure to be able to say a lot of family treasures. However, many mobile phone brands are in hot pursuit of dual camera. This does not, even the Apple iPhone 7 Plus can not use the dual camera. The new product vivi X9, which was released again in the past six months, caught up with the dual camera's east wind. But unlike the usual dual-camera phone, the vivo X9 is a front-facing dual camera phone. Released in the middle of the year vivo X7 with soft light self-timer, vivo X9 continued self-timer (photo) gene appears to be a matter of course. Vivo X9 uses 20 million + 8 million dual-lens combination, of which 20 million pixel camera based on Sony IMX376 build. It is reported that IMX376 is developed jointly by vivo and Sony. It is not to say that this is the highest-standard front camera, and it is also a standout on the rear (main) camera. Vivo X9 detailed parameters Good question, X7's self-timer is very good, why do we need front dual camera? Or, more frankly, the front dual camera value of vivo X9 is not worth us to pay? Large screen regression + ultra-narrow border Compared to the predecessor X7, the vivo X9's screen size increased to 5.5 inches. Although the 5.2-inch X7 feels light, the vivo X9 uses a 5.5-inch profile, reflecting the user's preference for large-screen phones. Despite the larger screen, the width of vivo X9 did not increase significantly. This is because the width of the border of the new machine is only 1.59 mm, and the big black side is observing since then. However, if the border is so narrow, will it not be easy to touch it? To this end, the Lord specifically tried the operation of the edge area and found that the system would not react when long pressed close to the frame; for light touch, sliding, judged by normal operation. When we grab the phone or press the palm of the hand to the screen, this will not cause a false touch. Of course, the best way to avoid misuse is to add a leather case. For a self portrait camera, front dual camera is a good idea, but it also brings problems for the design. Counting the handset, sensors, and soft lights, there are five "holes" on the top of the vivo X9. The designer is trying to keep the balance between the two sides of the receiver. The left double camera and the right sensor and soft light are small openings. Obsessive-compulsive disorder partners do not have to worry. The black version does not have this trouble. As for the buttons, although the iPhone's Home button is touched, the vivo X9 still maintains a touch + physical design. He consulted Vivo's little buddy about this, and their representation is that some users are very comfortable with the touch of the Home key, but there are also feedback feelings that users like the physical buttons. In the absence of conflict, the two are merged (press and touch both return to the homepage). In fact, in addition to taking care of the user's feelings, the physical Home key is the basis of the IDWake function. Like X7, vivo X9 also supports fingerprint payment and double-click shortcut launch application. One of them is to quickly open the QR code payment page of WeChat or Taobao. Since the fingerprint recognition has been completed at the same time when the Home button is double-clicked, the speed from the lock screen state to the payment state is quite fast, and the convenience is not inferior to the NFC payment function such as ApplePay. As you can see from the back, the vivo X9 uses a new antenna design, and the antenna goes along the edge of the fuselage. The advantage of this design is that while the antenna area is larger, the overall sense of the fuselage is not diminished. From another point of view, as always, exquisite workmanship. Vivo X9 gave up the polished waistline on the X7 frame and replaced it with a ridgeline. This ridgeline allows the frame to produce a clear, dark visual effect, making the body look thinner. However, from the point of view of refinement, Shui Ye still prefers the X7 style. Vivo X9 main soft light double shot, in order to better test the effect of its beauty, blur, soft light, the water special weekend to work overtime (with her sister in the evening rushed to Guangzhou sand surface). Front dual camera makes selfie more fun Compared to antique-grade dual-lens SLR cameras, the development of dual-camera phones has only a few years of history. However, unlike the former, where the second lens is used only for shooting, the dual cameras of the mobile phone are technically more complicated and richer. According to the simple classification of functions, there are about three types - enhanced image quality, depth of field control, and 3D imaging. Here the vivo X9 uses a solution that produces depth of field, a 20-megapixel camera is responsible for imaging, and an 8-megapixel camera is responsible for recording distances. However, the dual camera is not simply to put two cameras together, or dual camera phones have already run through the street. Firstly, the dual camera has very high requirements on the coaxiality of the two cameras. For example, the coaxiality of the iPhone 7 Plus requires 0.35 μm. The second is algorithmic cooperation. Using different lens groups and photosensitive elements all require appropriate algorithms to take the ideal photo. At present, there are not many manufacturers in the world that master dual camera algorithms, and vivo is the choice to collaborate with ArcSoft (USA RainbowSoft) to jointly develop a virtual X9 algorithm. For the function of a mobile phone, Sony and ArcSoft were jointly built to reflect the vivo's ability to control the supply chain. Soft light beauty level still One hundred observations are better than others, and the following will immediately enter the experience session. Front said that in order to better test the water Vio X9's soft light double shot, specifically pulled sister to run to the sand in the evening to go. Friends who have been to Shamian at night know that even though it is an attraction but also a residential area, there is no other light besides the street light, so the night is very dim. The addition of dual cameras has changed the self-timer interface of the vivo X9. In addition to the soft light switch, HDR, dual camera blur, and dynamic photos have been added. The 20-megapixel camera built on the Sony IMX376 did not disappoint the author. Thanks to the larger lens aperture and sensor elements, the vivo X9 still achieved satisfactory self-portrait imaging in the low-light streets. For Asian skin, vivo X9 has a white and ruddy look more than X7. However, the graininess of the screen needs to be optimized slightly, which can make people look more delicate. Make selfie more fun Well, back to the core of the dual camera blur experience, vivo X9 has a F0.95-16 adjustable iris effect, the smaller the value, the larger the aperture is, the stronger the background blur is, the default is F2.8. The user can also enable the beauty mode at the same time when the dual camera mode is turned on. In fact, using the vivo X9 self-timer does not require much attention, as long as you follow the normal self-timer experience and press the shutter. Because the mobile phone will automatically track the scope of the face, and support the first photo after focusing. The photos taken in the dual camera mode are clearly indicated in the album. After entering the edit mode, you can select the focus you want. And based on this focus, you can also re-adjust the aperture value to re-render the blur effect. After confirming, the effect will prevail. You can share it with your circle of friends. From the viewpoint of proofs, the effects of photos taken with dual camera shots are obvious. The blurred background makes the photos more layered, and the sister as the subject also becomes more focused. As for the common problem of dual-camera phones in general, it is the unnatural nature of the transition between subject and background. The vivo X9 is also optimized. We look at the details of the enlarged photo, especially the hair part, and you can see that the identification of the main part is more accurate. More proofs. In fact, He also found another killer in front of the dual camera: usually some small partners in order to show a small face, in the self-timer like to hide behind others, it seems relatively large face. Now with vivo X9 there is no such opportunity, directly to give you a blur effect of 0.95 aperture, see you still hide. Intimate Funtouch OS 3.0 As early as the end of October, vivo announced the launch of Funtouch OS 3.0, and the vivo X9 release also loaded with the latest version. From the user interface to the actual experience, Funtouch OS 3.0 is an important version update. From vivo X9, the next group of vivo new machines will be loaded with version 3.0, so here we also focus on talking about what changes. The first is the invisible place, starting from the 2.5 version (vivo Xplay5) Funtouch OS joined the wisdom of the engine mechanism for the processing load, background programs, memory allocation, power saving strategies and other corresponding adjustments. Without the need of user intervention, let the system maintain a smooth, power-saving state for a long time. On this basis, Funtouch OS 3.0 adds application freeze and active defense. The former is when the user's commonly used application is in the background of the system, to freeze its operating environment, without power consumption, but also quickly wake up thaw; the latter is analyzed from the vivo cloud database, intelligently determine the current possible cause high power consumption , Malicious tampering, and performance and stability degradation of services and applications. Compared with the program optimization process, the change of the operation interface undoubtedly brings more freshness. Funtouch OS 3.0 uses a more flat icon with a more flat style. The radius of the rounded corners has also become larger. The first impression is that it is more fashionable (as a contrast vivo X7 with Funtouch 2.5). Task management was stripped in Funtouch OS 3.0's slide control center, so the shortcuts were more than one column and the operation became more convenient. The stripped task management has become a card type, which is the first time that the Funtouch OS uses the card task management design. Unlike general card-based task management, Funtouch OS 3.0 recognizes financial applications and blurs thumbnails to prevent voyeurism. As mentioned earlier, Funtouch OS 3.0 puts more system optimization into the background, so the options for the i housekeeper have also been greatly reduced, but the function of file management has been enhanced. WeChat and QQ are now used frequently, but it is not easy to find out the files they receive. Therefore, Funtouch OS 3.0 separates WeChat, QQ's storage directory, as long as you open the file management. In addition, Funtouch OS 3.0 manages the space occupied by the software to be more detailed, and the system and each application's cached junk files are distinguished. For example, the WeChat, chat logs, pictures, and videos are categorized and the junk files are cleaned up more cleanly. Timely, it also avoids unnecessary accidental deletion. Speaking of WeChat, Funtouch OS 3.0 also added a great feature, which is WeChat article bookmarks. Reading articles in a circle of friends or subscription numbers has become a daily habit of many users. However, the general mobile phone can not perform other operations while reading, otherwise it will open a new article again. Funtouch OS 3.0 does not have this trouble. When you switch to the chat interface while reading an article, you will leave a button to return to the article page to easily jump between chat and reading. Funtouch OS 3.0 has joined the children's model for children's use of mobile phones. Child mode entered by password or fingerprint (open eye protection by default), in addition to limiting the time of use, can also limit open applications and prohibit all applications of internal purchase behavior. The split screen function of the Funtouch OS Signature has been greatly enhanced in this version. In addition to the split screen when watching videos, 3.0 has added more support, such as Lynx, NetEase, headlines and other common applications. The kind of scene that is repeatedly switched between shopping and chat is also history. Lastly, we introduced the Super Audio mode. According to the introduction, this is a combination of vivo and Waves based on MaxxAudio. The activation of Super Audio allows the player to obtain a wider sound field effect, and the volume is also significantly improved. Despite the increase in power consumption, it is better to listen to movies and games for a better listening experience. Automatic HDR+ Dynamic Photo In addition to upgrading the front dual camera, vivo X9 main camera is also from the X7's 13 million-megapixel camera, changing to 16 million pixel camera (F2.0 aperture). According to the parameters of the photosensitive element area of ​​1/2.8 inch, this camera should be built based on the Sony IMX298. The IMX298 is an RGBW four-color architecture that supports PDAF phase focusing and is a very mature solution. Although the self-timer is the main function, the vivo X9 still incorporates automatic HDR and dynamic photo functions to increase the user's interest in taking pictures. Vivo X9 uses automatic HDR setting, and the camera system judges according to the ambient light ratio. The HDR camera takes a composite time, so the auto HDR mode will wait a little while pressing the shutter before pressing the second time. However, this time is relatively short and has little effect on daily shooting. In fact vivo X9 also takes into account the user's capture function, in the HDR automatic mode long press the shutter will automatically enter the continuous shooting mode. Judging from the actual proofing experience, this feature is very suitable for small white users, because it can save a lot of set-up troubles, and can easily avoid some dark and contrasting photos. Anyway, it is the default automatic HDR to use the water master, pay attention to the stability of the handheld when shooting. Vivo X9 has added a dynamic photo shooting function, previously rely mainly on some third-party software to shoot. Dynamic photos can record sounds and video clips for a certain period of time, but there is no difference between operation and normal photographing. Dynamic photos emphasize interest because they record some casual moments. However, these photos must be viewed in the mobile phone album, but also take up more storage space. In terms of imaging quality, the daytime vivo X9 meets the expectations of the IMX298 model, and the color reproduction is more natural, that is, the saturation is low. The performance of night view and low light needs to be optimized. The main performance is noise. Performance is quite satisfactory Vivo X9 is equipped with a Snapdragon 625 eight-core processor running at 2.0GHz and equipped with 4GB of RAM and 64GB of storage. The Snapdragon 625 uses a 14nm process with eight Cortex-A53 cores and Adreno 506 GPUs. Xiaolong 625 performance is not particularly outstanding, the highlights are the low power consumption and low heat brought by advanced technology. For younger partners who are more persistent with performance, consider the vivo X9s Plus or the flagship vivo Xplay6. In the evaluation software PCMARK which emphasizes the practical application experience, the vivo X9 score is close to that of the Xiaolong 652. Life: Strict management of power consumption in the background Vivo X9 has a built-in 3050mAh battery, which has a slight increase of 50mAh over the X7. This battery capacity belongs to the current mainstream level. The battery life of a mobile phone is a part of it, and power saving management is equally important. In addition to power-saving mode, Vivo X9 will also prompt high-power applications in the background and provide shutdown operations. In addition, vivo X9 can also be banned for the application of an application associated with launching multiple applications. In terms of actual power consumption, Shui Ye has played 30 minutes of "Street Basketball" under the WIFI connection with 50% brightness, and watched a 30-minute online drama. The two applications consume 10% and 3% of the power respectively. In order to play "street basketball" smoothly, the vivo X9 is operating in the normal mode, but it is still 10% more power consumption in 30 minutes. We hope that the next version will be optimized. Vivo X9 supports 9V/2A flash charge, emergency charge from 0%, and 12% power after 10 minutes. The total charging process takes less than 100 minutes, which is the upper level for a cell phone with a 3050mAh battery. The key is that compared to the X7, the vivo X9 has a lower fever when flashing. Edit Comment Self-portraits and beauty are almost equal before the vivo X9, and the understanding of the phone's self-timer is limited to portrait optimization. Therefore, in the innovation of the self-timer function, the vivo x9 with its dual-camera blurry front view undoubtedly has reached the forefront of the industry. In the past, software optimization was used. Now that the hardware is not in the hardware, I'm sorry to say that I am a self-timer. After talking about the vivo X9 release, many users who just started X7 complained about buying it. Judging from the life cycle of the X7 series, this time the vivo X9 is a bit out of the game. But not that vivo ignores the user's feelings, because this is a change in the industry chain, and vivo just seize this node. As a main self-timer product, vivo X9 used the industry's leading solutions for the first time, and it was also a response to loyal customers.
