When there are too many applications open in the background, the system may run slowly and the applications will not respond. It is recommended that you clean up the temporarily unused applications in the background in time during daily use to avoid this situation.

1. If it is a device that supports virtual navigation, I suggest you click? , and then click Clean daemon.

2. If the device supports the front navigation key, the navigation bar will be turned off by default when leaving the factory. You can slide the navigation key left and right to display the recently used applications, and then click Clean Background Process.

After calling up the background application list, you can click Lock on the application to prevent it from being cleaned up by mistake.
