What if the camera in front of the phone can't be turned on? Huawei

If the front camera of the Huawei mobile phone you are using cannot be turned on, please follow the following steps:

1. Check whether the application using the camera is open.

Android requires that only one application can turn on the camera at the same time. When another application opens the camera, the camera will not open. Some applications may not be able to release cameras in time due to their own design reasons. Such as flashlights, two-dimensional code scanning and other programs.

You can close the camera-related applications, and then enter the camera to try.

If you are not sure what application it is, you can restart your phone, then enter the camera and try again.

2. Clear the camera data

Enter settings, search application management, find the camera, and click Save >; Delete data.

Tip: This operation will not delete the photos in the library, but only restore the camera settings and other data.

3. Check the permissions of the third-party application

If the camera can't be turned on through the three-party application, I suggest you go to Settings, Search and Access Rights Management. On the Permissions tab, click Call Camera/Video Camera to open the camera permission of the corresponding application.

4. Use the "smart detection" function to detect the camera.

Please check it on the mobile phone service APP: enter service > I want to test > enter the test, and complete the test according to the mobile phone prompts. If it is a camera hardware problem, please back up the data (WeChat /QQ and other applications need to be backed up separately) and take the purchase voucher to Huawei customer service center for testing.

5. Restore the equipment to the factory settings.

It is recommended that you back up your data (WeChat /QQ and other applications need to be backed up separately), restore your mobile phone to factory settings and try again:

Enter the settings, search to restore the factory settings, and complete the operation of restoring the factory settings according to the phone interface prompts.

If the above operations still can't solve the problem, please back up the data (WeChat /QQ and other applications need to be backed up separately) and bring the purchase voucher to Huawei customer service center for testing.
