Screen lock

There are several ways to lock the screen. The security level of each lock type is listed
below in order of weakest to strongest:
• Swipe – no protection, but you have quick access to the Homescreen
• Face Unlock – unlocks your device when you look at it
• Unlock pattern – draw a simple pattern with your finger to unlock your device
• Unlock PIN – enter a numeric PIN of at least four digits to unlock your device
• Unlock password – enter an alpha-numeric password to unlock your device
It is very important that you remember your screen unlock pattern, PIN, or password. If you
forget this information, it may not be possible to restore important data such as contacts and
messages.
