							Locking and unlocking the screenWhen your device is on and left idle for a set period of time, the screen dims 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 left or upward on
the screen to unlock it. You can change the security settings later and add other
kinds of locks. See 
Screen lock on page 11.
