1, exit APP+ in the background to release memory.

Sometimes flashback occurs when the system is out of memory. At this time, we only need to exit the suspended APP or release the memory.

To release the memory, press and hold the power button to slide the shutdown interface, and then release the power button. At this point, press and hold the Home button until you return to the desktop. This move is used to release iPhone memory.

2. Upgrade or reinstall the mandatory retirement application.

When a single APP often flashes back, 80% may be a problem with a single APP. There may be program bugs in some places, and the solution is to upgrade or reinstall this APP.

Another situation is that the software you installed is not trusted by the mobile phone, which may be caused by downloading from the third-party application market or not upgrading the software version:

At this point, we can go to Settings-General-Device Management (also known as "Profile and Device Management") and add trust to related software.
