Facebook is testing a new photo sync system which automatically uploads photos taken on Android handsets to the web.
If that sounds familiar, that's because it is: Google+ already features an instant photo-upload feature which uploads all your shots to the cloud. Like Google's system, Facebook's new feature ensures your pictures remain private, placing them in a "Synced from Phone" tab inside your Photos page.
The sync feature currently appears to be available to a very small number of users, but there's already a help page up online so it's very much real. To find out if you're one of the users who have the feature enabled, navigate to your timeline on your Android, hit Photos, and see if there's a sync button at the bottom.
