After waiting for more than 2 months, the transparent exploration version of Xiaomi 8 finally went on sale. In addition to the transparent back cover that everyone is concerned about, it is not only the first model of 3D structured light face recognition in China (although it is PPT), but also the first model of fingerprint under pressure screen. As an aside, according to Xiaomi's models, these exploratory work should be done by the MIX series (muddled. jpg).
PS: The main purpose of the "Skillful Program" is to send the information of the new machine to everyone as soon as possible, so it will compress the shooting time, and the detailed picture appreciation, evaluation, and video will be completed later. Please look forward to it.
Ancestral QC3.0 fast charging head
Xiaomi 8 transparent exploration version uses transparent acrylic as the inner layer of the package. No wonder the box is so powerful:
There is only "signature card printed by Mr. Lei" in MIX series;
There is no change in the type of accessories compared with the ordinary version: data cable, fast charging head, clip, instruction manual, Type-C headphone adapter, phone case;
The phone case has been greatly upgraded, with silicone on the side and transparent hard case on the front. Wearing the case will not affect the installation of the transparent back cover. The phone case is higher than the camera, so there will be no embarrassment of "wearing the case will also rub the camera" in the ordinary version;
The data cable and charging head have also been replaced with red and black colors (the tongue has been replaced with red);
However, the charging head has not been promoted to QC4+. It is still the MCY-08-ES that has been in use since Xiaomi 6.
The biggest change on the interface is that the power button and the tongue of the type-C interface have changed to red
After 3D structured light face recognition, the number of forehead openings soared, the status indicator light was hidden under the receiver, and the camera moved two positions to the right. Except for the film with bangs, other types of ordinary Xiaomi 8 films cannot be used universally.
The battery has carbon fiber texture stickers, and the NFC coils and cables on the battery are fully displayed
The biggest appearance of Xiaomi 8 transparent exploration version is the transparent back cover. Although it is a transparent rear cover, it is coated with a certain degree of reflectivity, and its edge has a black gradient. Next to the camera is a decorative motherboard. The capacitors on the motherboard are real, but they are not powered on. They are mainly used for decoration and passive cooling.
It should be noted that most SoCs will be packaged with memory. Even without this decorative motherboard, the real SoC cannot be seen. Step back. If the SoC is exposed directly without overlaying the memory package, it will roll over. After all, many Snapdragon 845 models are equipped with heat pipes, making SoC run naked is equivalent to making "iron plate bear paw". However, the netizens' response to this was so great that the public relations team had to be promoted for the pot. The engineering team and mobile phone both said they were helpless.

Sensor information, face unlocking page, pressure sensing test
The screen (model: ea8074_notch, cmd mode) and camera of Xiaomi 8 transparent exploration version are the same as those of the ordinary version. However, the infrared camera for 3D face recognition has become OV9282, while the ordinary version is OV7251. The pressure sensor on the right side of the above figure can read more than 2048, but I dare not press it hard again. When reading 2000, I feel that the screen is about to burst (smile and cry).
3D face recognition and fingerprint test under pressure sensitive screen of Xiaomi 8 transparent exploration version
The speed of 3D face recognition is very fast, and it is almost catching up with 2D face recognition. Xiaomi's feature is that it can choose whether to use 3D or 2D face recognition, but it doesn't have the look and unlock function on iPhone X (it can only be unlocked by looking at the phone), and its security is lower. I hope OTA can make up for this function later.
The key to Xiaomi's fingerprint under the screen is to add pressure assistance, and its experience has improved several orders of magnitude. The speed is not much different from the existing products, but because of the vibration feedback of the pressure sense, people will have the illusion that the speed increases a lot. However, the recognition rate and angle compatibility are higher than those under the screen (even more comfortable than Xiaomi's 5s ultrasonic fingerprint). In addition to blind touch, there is no problem with the experience. There is a pressure sense in the fingerprint identification area, which is disguised as a power on button. The pressure sense can be unlocked directly by lighting the screen. To sum up, this is the first time that the experience has caught up with the offline fingerprint of the traditional fingerprint, which is more surprising than the 3D face.
From the disassembly of Sina, the fingerprint identification module of Xiaomi 8 transparent exploration version is similar to the setting of vivo X21 UD, rather than the wide-angle identification camera of NEX. In addition, the sensor is unlocked according to the thumb of the right hand and tilted to a certain extent. Whether this will affect the speed and angle compatibility of left hand fingerprint recognition, we will test and compare it in future articles.
Finally, conveniently measure the charging power. The power is 5%. As a result, the peak value of off screen is not 15W, and the power is lower than that of the ordinary version. If the power is reduced for heat dissipation, the pot will be backed by a transparent back cover.
