Huawei's mobile phone calls black screen.

During the call, when the phone is close to the ear or covered by other objects above the screen, the phone will automatically turn black. This is set by Huawei mobile phone itself, which can wake up the screen at a certain distance from the top of the screen. It's not the phone fault, please feel free to use it.

Suggestion:

If the phone leaves the ear and the screen is still black during the call:

1, using non-standard protective film will cover the sensor, so it is recommended to buy this special screen protective film for mobile phones.

2. After the phone is set to automatically turn off, it will automatically turn off after the set time.

3. If the above methods still can't be solved, it is suggested that the data backup should bring the purchase invoice to the after-sales service outlets for testing. The address information query method of Huawei Customer Service Center is as follows:

1. You can find the nearest service center through the "Service" page in the member service APP that comes with your mobile phone;

2. There can also be an after-sales outlet inquiry address entrance at the bottom of the official website page of Huawei Mall;

Tips: It is recommended to back up the mobile phone data before going to the after-sales outlets, and you can communicate with the outlets in advance to confirm the business hours.
