Why does Samsung mobile phone c7 always flash back?

1. Too much mobile phone cache will lead to slow operation and flashback. You can find an application with flashback function through Application Manager to clear data and cache attempts.

2. Too many programs running in the background will cause the software to flash back, so you can try to close the programs running in the background.

3. A low application version will lead to software flashback. You can use flashback to uninstall the application and then install the latest version. Some softwares have certain requirements for the version of the mobile phone system. If the system version is too low, it will also cause the software to flash back. You can try it by updating the mobile phone system version.
