The most beautiful weather flashed by.

There is too much cache garbage and too many running programs.

1. According to official website, the most beautiful weather, there is too much garbage in the cache: in the process of using the software, some junk files will be generated. If the mobile phone is not cleaned for a long time, it will become more and more stuck and will flash back.

2. Too many running programs: Without setting, a lot of software will run by itself, while too many background programs on the mobile phone will cause insufficient memory, which will cause the application to flash back.
