There use to be an option called Users under Accounts and backup in Settings that allowed you to add & manage multiple users but for whatever reason, Samsung seemed to have removed the functionality entirely.
Balls! it's handy if I give phone to kids they don't fill my screen up with games and stuff. It used to be really handy. Why take it out, also I just thought ...it was android option wasn't it?
Yes, it is a feature of Android & is part of the vanilla Android experience. However, from what I understand some OEMs opt to omit the functionality. Sucks! seeing as how Samsung did support it in the past.
