Locking and Unlocking the Screen

When your device is on and left idle for a set period of time, the screen darkens to save

battery power and locks automatically. This lock prevents unwanted actions on the

touchscreen when you are not using it. When you buy your device, a basic screen swipe

lock is already set. This means you have to swipe upward on the screen to unlock it. You

can change the security settings later and add other kinds of locks. See
