What if the camera on the iPhone is turned on?

There are many reasons for the black screen of the camera before and after the iPhone. It is recommended to restore the factory settings or upgrade the camera to see if there will be a black screen. If there is still a problem, be sure to consider whether it is a hardware problem! If there is something wrong with the hardware, it can only be repaired.

The reason for the black screen:

First, the memory problem: Under normal circumstances, when the mobile phone stores too many things, we generally feel that the mobile phone is running a little slow, but this is a sign that the mobile phone will have a black screen.

Second, contact problems: sometimes accidentally knocking on the phone may also lead to poor contact with the screen of the phone.

Third, the battery problem: the effective use time of mobile phone batteries is one year. Long time or improper use will affect the aging of mobile phone battery, so there may be a black screen.

4. Conflict: There are only more and more softwares, but some softwares may have some conflicts with the mobile phone itself, which may lead to a black screen after installation.
