This app can automatically turn on and off touch-blocking on-screen edges when an app is launched or closed. This will prevent you from accidentally tapping a place when playing a game or watching videos. It's also useful when you have a screen protector or a screen protector that has an edge, like the Galaxy S8 Edge screen protector.

It has a 30-time trial limit on auto-blocking and block execution. It requires special settings to run in the background for OPPO devices. This is to ensure that the app functions properly. This is needed because this app uses user accessibility services, which need to run in the background.
