Depending how you use your phone, you may want to set some form of automatic screen lock to prevent unauthorized access. If a lock has been set, the screen locks when your tablets display goes to sleep. Follow the simple steps below.

• When you touch the power button to wake up a locked tablet, you must take some action, ranging from a simple swipe to typing a lengthy password, to unlock it.
• You can set locks of different strengths using your tablets lock settings. To do so, go to Settings, Personal, Security, and then Screen lock and touch the type of lock youd like to use.
• Face Unlock is one of the options available. After youve set it up, you can unlock your phone simply by looking at it. Although Face Unlock is not very secure, it can be convenient and fun to use.
• Give it a try. Go to the Screen lock setting described above, touch Face Unlock, and follow the instructions.
• After you set up Face Unlock, look under Settings, Personal, and then Security for two additional settings: Improve face matching and Liveness check. Use these to make Face Unlock more reliable and secure.
