Huawei's mobile phone address book flashed back

If the phone is turned on for a long time, for example, it has not been turned off for many days, it may accumulate too much cached data. Too much cached data will take up too much running memory, resulting in problems such as cell phone jamming and flashback. You can go to Settings to find application settings, clear data or cache, or restart your phone to solve these problems.

2. There are too many programs running.

Too many programs running in the background of the mobile phone will also cause insufficient memory, which will lead to flashback problems. You can try again after closing the unused daemon.

3. System file problem.

If the system has been updated recently, it is likely that some key files were damaged during the installation or use of the system. You can try restarting your mobile phone. If it fails, you need to reinstall the operating system. Pay attention to backing up important data such as address book in advance.
