In order to start sharing with S Beam, first you must activate NFC and S Beam in the phone settings.
No need to open a special sharing app. If you are looking at a photo in your gallery and you want to share it, just touch your phone to another Galaxy S III (both devices display must be powered on with screens unlocked). If you want to share a video you are watching in the video player, just touch your phone to your friends S Beam enabled device.
-With the content you want to share, touch the back of your phone against the back of another Galaxy S III.
-The content will shrink, and you will see a message to tap the screen to start sharing.
-Tap the center of the screen and hold the phones together until the sharing starts.
-With S Beam, you can separate the phones and let the sharing continue in the background.
-S Beam shares movies, photos and your legally sharable music files with other Galaxy S III devices.
The S Beam makes everything easier, now you don’t have to give your number or email just to share files. A must need.
