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.
Android Beam
You can beam a web page, a video or other content from your
screen to another device by bringing the devices together
(typically back to back).
Before you begin: Make sure that both devices are unlocked,
support Near Field Communication (NFC), and have both NFC
and Android Beam turned on. To check, go to Settings > Wireless
& networks > More. Also make sure that you know where the NFC
area is on the back of both devices – typically in the centre.
1. Open a screen that contains something that you’d like to
share, such as a web page, YouTube video or place page in
Maps.
2. Move the back of your device toward the back of the other
device. When the devices connect, you hear a sound, the
image on your screen reduces in size and you see the
message Touch to beam.
3. Touch your screen anywhere.
The other device displays the transferred content. Or, if the
necessary app isn't installed, Google Play opens to a screen
where your friend can download the app.
