The photos and pictures in the mobile phone are all negative. What should I do?

"The following actions are recommended:

1. Try changing the wallpaper of your mobile phone.

2. Trying to restart the mobile phone may be a temporary error in the mobile phone software.

3. Check whether the negative color function (setting-auxiliary function-negative color) is turned on, and restart the phone check after turning it off.

4. Back up data (contacts, text messages, photos, etc. ) and restore the factory settings.

5. The problem still exists. It is recommended to take the mobile phone to the local after-sales service center for testing. "
