What's wrong with the camera behind the phone?

The mobile phone prompts that the camera cannot be used. I suggest you:

1. Check whether the camera function can be used normally. If this prompt appears when using third-party software, it may be that the application currently in use does not support cameras. It is recommended to check whether there are related operations in the software settings.

2. Try to change other software.

2. If this happens when taking pictures with your own camera, it is recommended to turn off your phone and restart it.

3. If the mobile phone supports dual cameras, I suggest you try to change a camera.

4. Reset camera parameters: camera-settings (gear icon)-(settings)-reset.

5. If not, please back up the data in your mobile phone (such as address book, multimedia files, etc.). ) and restore the phone to the factory settings.
