Android 12 is expected to support screen rotation with face, so you don’t have to worry about lying down to play with your phone

      Android 12 will be officially released in the second half of 2021, and some new features have been gradually exposed in recent days. According to foreign media TomsGuide, Android 12 will solve a screen rotation problem that has troubled users for a long time, and can detect the direction of the face to automatically rotate the screen. However, this feature will initially be exclusive to Google's own Pixel phone.

     When the current mobile phone turns on the screen rotation mode, the phone will use the gravity sensor to automatically adjust the screen so that it can rotate automatically when reading or watching videos in horizontal mode. However, once the user lies on his side in bed and plays with the phone, the automatic rotation function will be very inconvenient, because the user's head is at a 90-degree angle to the ground and the phone screen is always crooked. In addition, when using the phone in a side-lying position, even if you use games or video applications that only support horizontal screen, the phone will occasionally fail and the screen will occasionally rotate 180°. This requires the user to manually turn off the screen automatic rotation function before lying down to use the phone.

　　Foreign media 9to5Google reported that the new feature of Android 12 will detect the direction of the user's head and then use it as a reference to rotate the screen. This does not require relying on the gravity sensor, and the screen rotation direction can be kept consistent with the user's expectations at any time.

　　IT Home learned that this function is realized by using the front camera of the mobile phone. Google Pixel 4 also used the front camera for facial recognition to unlock the phone, but Pixel 5 canceled this function. If you want to use the front camera to assist screen rotation, you need to solve the power consumption problem, or rely on other sensors to help realize this function.

　　According to 9to5Google, the automatic screen rotation function that detects faces will be launched first on Pixel phones, but it also supports other Android phones. The double-click screen gesture function was previously leaked in the Android 11 preview version, but it was not officially released. Foreign media said that Android 12 is expected to officially support the double-click gesture function. Google officials did not reveal too much about the new features of Android 12. Before the official version is released, developers can get the Android 12 preview version and are expected to learn about the latest developments of Android 12 in advance.
