What should I do if the rear camera of Apple xs max phone suddenly turns black?

If the screen color of the mobile phone is abnormal, such as black screen, splash screen, flower screen, white screen and red screen, it is suggested that:

1. Click the Back key to try to exit the software. Exit and re-enter if possible.

2. If you can't quit the software, it is recommended to restart the phone: press and hold the power button and volume button for more than 7 seconds at the same time to restart the device;

3. If the screen still appears after opening the software again, this situation may be related to the software used. If you downloaded the software yourself, it is recommended to uninstall the software and reinstall it.

4. If you have your own system software, it is recommended to try to update the version of the mobile phone system: Please go to Settings-About the mobile phone (about the device)-Software update (system update)-Update (please back up the data in the device before upgrading).

5. If it is the latest version, please back up the data (contacts, information, pictures, etc. ) and then try to restore the factory settings.

If the problem still exists, it is recommended to take the purchase invoice, warranty card and mobile phone to the local mobile phone purchase office for repair or to the nearby mobile phone repair shop for repair.
