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. In other words, you have to swipe up or down on the

screen to unlock it. You can later change the security settings and add other kinds of

locks. See 

Setting a screen lock

 on page 102.
