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
Screen lock on the 38page.
