Why is the iphone7plus camera black?

The reasons for the black screen of the iphone 7plus mobile phone camera are as follows:

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.

1, press and hold the power button 10 second to automatically restart the phone.

2. Press and hold the power button and the Home button for 5 seconds to force the shutdown, and then turn it on later.

3. Connect the power supply, press and hold the power button and the Home button for 5 seconds, and force the shutdown. If not, use up all the electricity until it is turned off, and then charge it and turn it on.
