What about the black screen of iOS 16.1.1? How to solve the problem of sudden black screen in iOS 16.1.1 official phone calls

1. The distance sensor of the mobile phone is blocked

Most smart phones are equipped with a distance sensor beside the handset. When you make a call and your face is close, the screen of the phone will automatically turn off, while when the phone is far away from your face, the screen of the phone will turn on again. This design can increase the battery life of the phone. Therefore, the black screen of the mobile phone may be caused by the distance sensor being blocked. Check whether there are foreign matters in the upper front earpiece attachment of the mobile phone. If yes, please clean it up. The general problem can be solved.

2. Distance sensor failure

When the distance sensor fails, it is not possible to correctly judge whether there is an object close to it, which may lead to a false judgment that there is no object close to it when making a call, thus closing the mobile phone screen. Therefore, it is recommended that the mobile phone be sent to the official designated maintenance center for maintenance.

3. The distance sensor software of the mobile phone is set improperly

If the distance sensor is not set correctly, it may also lead to a black screen. It is recommended to go to the mobile phone [Settings] - [Display] - [Sensor Verification] to verify again.

4. The sensor fails due to lack of leather pad

This usually happens to the phone after the phone is disassembled or the screen is changed. In fact, the touch screen is replaced or the mat at the bottom of the disassembly sensor is lost. The solution is: there are two small holes above the original touch screen, and a small cushion under the hole, which is about 3mm thick. The two holes are just the same size and distance as the small holes on the touch screen. You can just make one and paste it.
