How to solve the flashback problem after iPhone upgrade?

Mobile phone software is developed based on a version of the mobile phone system. Once the mobile phone system is upgraded, some software can't adapt to the new functions of the new system, and instability will occur. Flashback is a typical performance.

The solution is as follows:

Double-click the "Home button" of iphone to bring up the background management window, and delete the flashback application from the background. In the background management, I see many open background applications, and then gently slide the application that needs to quit with my hand, and the application will quit. If exiting the flashback application from the background still doesn't solve the problem, you can try to open the background management again and close all applications in the background.

Press and hold the "power button" on the top of the phone, and a red shutdown arrow will appear at the top of the screen, then slide the arrow to turn it off. Finally, press the "power button" to restart the machine.

Open Settings on the iPhone home screen, then find Reset in the General Manager, and finally click Reset All Settings. The function of this function is to restore all the settings of the mobile phone to the original state, but it will not delete the existing data and media on the mobile phone.

Reinstall. Press and hold the icon of the application to be deleted on the home screen for more than 3 seconds, and then the icon will shake. Click the "X" on the icon of the application to be deleted to delete it.

If the iPhone has escaped from prison, check some plug-ins and some new functions installed before the problem occurs, and try to delete some plug-ins to solve the problem of automatic exit. Because of the influence of some plug-ins, some applications may be incompatible, resulting in the situation that they cannot be opened normally.
