What kind of plane are you consulting? You can try the following:

1. You can clear the memory with one click to free up space.

2. Clean up the cache files in the mobile phone security assistant (I housekeeper)-mobile phone acceleration.

3. Find the program you often use in Settings-More Settings-Applications-Installed, click to enter the information interface of the program, and select Clear Cache and Data.
