•Add "Force Lock" option in settings
(Enable "Force Lock" if your device turns on after locking.)

(If you use it every day/like this app, please buy the donate version/rate ★★★★★ ^_^)

Notes:
1.Read the app description / screenshots if you encounter problem during uninstall
2.For device running Android 4.X, sometimes flashing (screen on then off again) may happen, try fix it by enabling 'Force Lock' in Lock Screen Settings.
