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 that you have to swipe upwards on the screen
to unlock it. You can change the security settings later and add other kinds of locks.
