Audio commentary

Hello, everyone. The meeting will answer your questions. Many people still don't know how Huawei turns off the black screen when making a phone call, and how Huawei turns off the black screen when making a phone call. Now let's take a look at it.

Answer:

1. Distance sensors are blocked, and most smartphones are equipped with distance sensors next to the handset. When making a phone call, when the face is close, the phone screen will automatically turn off, and when the phone is away from the face, the screen will light up again. This design can increase the service life of the mobile phone. As a result, the black screen of the phone may be obscured by distance sensors. Check the handset attachment at the top of the front of the phone for foreign objects. If you please clean it up, the general problems can be solved.

2. How to clean Huawei mobile phone:

3. Most of the files in the phone are stored in the phone's folder. In fact, some useless cache files are saved in folders and Mobile Manager can't clean them up. This setting is enabled by default on the phone, and its function is to transmit the daily use of the phone and some data to Huawei officials, who will analyze the data to identify areas that need to be improved or optimized to enhance the user experience. But in fact, it has little impact on users. If it is not opened, it will save a lot of mobile data and will not affect the mobile experience. Whether you open it or not depends on your choice.
