With the application Football 4k Screen Lock you can set your phone to be secured by a passcode, instead of the default Android pattern lock. This lock screen allows you to set the code to be a certain number, slide up to unlock, or you can just slide up to unlock. You will be asked to enter the code every time your phone is unlocked and it also provides you with the option to set a picture to display on the screen while the phone is locked. You can also choose a theme, font, and color scheme, and also activate/deactivate notifications.
