After ip7p, the camera took a shadow. Did you take a video?

1, the light on the camera behind the mobile phone is covered and needs to be wiped off.

2. The mobile phone cable is loose, which is less likely and can be disassembled and reinstalled.

3, the rear camera is damaged, and this probability is also small.

4, that is, iPhone system problems, most of which occur in jailbreaking and installing illegal third-party software. If the mobile phone is still under warranty, you can go to Apple for free repair. 1, unofficial solutions include forced shutdown-restart-turn on the front camera-and then turn to the rear camera. 2. Apple advises users to check whether there are obstacles in front of the camera, and then turn it off and on again. If it fails, manually restart the device and turn on the camera immediately after turning it on, and try to switch the camera back and forth. If all the above methods fail, users can choose to go to the nearest Apple retail store or authorized dealer for help.
