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 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
on the 11 page.
