Why does the application flash back?

The following reasons can be found when the mobile phone system software flashes back or the third-party software flashes back:

First, clean up the background program; When we use a software and habitually return to the desktop, we often don't really quit the program, and the program is still running in the background. Too many background programs may lead to flashback.

Second, restart the attempt; If the APP flashes back or can't be opened, you can try to restart it.

Third, clear the program cache; With the increase of mobile phone usage time, there will be more and more program caches. In this case, it will lead to slow operation and flashback. You can go to Settings-More Settings-Applications-All, find the software that is flashed or unavailable, and clear the cached data.

Fourth, update the reloading software; When the App flashes back, let's first see if this app should be updated. If there is no new version, we can try to uninstall the application and then reinstall it.
