Try Face Unlock
You can set an automatic screen lock for your tablet. After you set
a lock, the screen locks when the display goes to sleep or when
you press the Power button.
You can set locks of different strengths using lock settings:
1. Go to
Settings > Personal > Security > Screen lock.
2. Touch the type of lock you'd like to use.
Face Unlock is one of the options available. After you've set it up,
you can unlock your tablet simply by looking at it. Although Face
Unlock is not very secure, it can be convenient and fun to use.
TIP: After you set up Face Unlock, look under Settings >
Personal > Security for two additional settings: Improve
face matching and Liveness check. Use these to make Face
Unlock more reliable and secure.
Share content with Android Beam
You can beam a web page, a video, or other content from your
screen to another device by bringing the devices together (typi-
cally back to back).
Before you begin: Make sure both devices are unlocked, support
Near Field Communication (NFC), and have both NFC and Android
Beam turned on.
1. Open a screen that contains something you'd like to share,
such as a webpage, YouTube video, or place page in Maps.
