1. Enter the phone and find the "Security Center" on the desktop. (Example: Red Rice 4X)

2. First click and select "Optimize Now".

3. Followed by "garbage cleaning" and "optimization and acceleration".

4. Because we often use WeChat, we use "WeChat Special Cleaning" to clean up the junk files and WeChat cache of WeChat.

5. Then select "Deep Cleaning" to clean up the pictures and videos automatically saved in the chat.

6, followed by "qq special cleaning", which cleaned up the QQ chat cache garbage and also made a deep cleaning.

7, followed by "mobile phone slimming", cleaning up application cache files and so on.

8. Finally, we'd better "restart the mobile phone" so as to return to the mobile phone desktop smoothly, and we must ensure that there is enough available storage space for daily use.
