Why did Apple's mobile phone suddenly flash?

The sudden flicker of iPhone when taking photos is caused by abnormal camera format parameters.

1. Unlock the iPhone to the home page of the screen, find the settings and open it.

2. After entering the phone's setting options list, find the next camera setting.

3. In the details page of the camera, select Format Settings to open.

4. Changing the option in the format management page to the best compatibility can solve the problem that iPhone flashes suddenly when taking photos. (When the format parameter is abnormal, it will cause the camera to flicker, which can be avoided by using the best compatibility setting. )
