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 .
