My HUAWEI phone/tablet screen turns on or off unexpectedly during calls

Problem:

The screen turns on or off during a call (including a call and a voice call in a third-party app).

• Screen off when calling: The screen turns off when the device is not close to the ear.
• Screen on during calls: The screen stays on when the device is placed on a table.
• Screen on during calls: The screen stays on when the device is close to the ear.
• Turn off screen during calls: The screen turns off when the device is not close to the ear.
• Screen off after a call: The screen remains off after the device is moved away from the ear.

Cause:

The proximity sensor is usually located under a small round hole at the top of the device screen. The position of the proximity sensor varies depending on the device model. For details, refer to the appearance diagram of your phone/tablet. You can visit the Huawei consumer business official website, enter your device model and "appearance diagram" (for example, HUAWEI Mate 80 appearance diagram), and select Support to find the required device appearance diagram.

The proximity sensor works properly:

The screen turns on or off during a call due to the system settings of your HUAWEI phone/tablet. To prevent accidental touches on the screen from ending a call, the system enables the proximity sensor by default. When you are on a call and the proximity sensor is blocked, the screen will turn off to reduce power consumption and heat generation. This is normal and does not indicate an issue with your device.

The proximity sensor cannot work properly:

The proximity sensor cannot work properly if you close the folio cover, enable the hands-free mode, use a headset to make a call, return to the home screen or another app screen during a call, or if you are in a non-voice call scenario (including video RBT, video call, and one-way video), or if the call is not connected or is being ended. In this case, you need to press the Power button to turn on or off the screen.

The feature performance of the device deteriorates:

Screen-on/off delay, freezing, and other issues are caused by feature performance deterioration.

Solution:

If the screen does not turn on during a call when the top of your phone/tablet is not blocked, perform the following steps to troubleshoot:

1. Check whether the proximity sensor is blocked (for example, by a protective film with black edges, a protective case with a wrapped edge, or a thick tempered glass screen protector) or dirty. If so, remove the obstruction or clean the sensor, and try again. It is recommended that you use official HUAWEI protective cases, covers, and screen protectors with your phone/tablet, and keep your device clean during daily use.

2. Check whether the proximity sensor feature is working properly:

After making a call, keep the call screen displayed. Cover the proximity sensor on the screen with your hand and check whether the screen turns off. Then remove your hand and check whether the screen turns on. If the screen turns off when you cover the sensor and turns on when you remove your hand, the sensor is working properly. If the proximity sensor cannot work properly, restart your device and try again.

3. Update your device to the latest version and try again.
4. If the issue persists, back up your data and take your device and proof of purchase to a nearby service center for assistance.
