OPPO mobile phone takes up a lot of memory, how to clean it up?

Hello, the "other" in the mobile phone storage includes the cache formed when you usually download the application software and run the software, including the cache of videos, the cache generated by playing games, and the cache of pictures generated by surfing the Internet. Often after a movie is finished, the corresponding cache will be stored there, so the "other" will become bigger and bigger. In this case, it is recommended that you go to File Management-Storage-File Cleaning to clear some unnecessary cached data and empty folders in your mobile phone. Uninstall unnecessary third-party applications on the mobile phone, and empty the system cache to release more space. Clear the cache: When the phone is turned off, press and hold the power button and the volume reduction button at the same time to enter the engineering mode. Select the option to clear the cache through the volume button (don't choose to clear user data), and the system will automatically clear the cache for you.
