I've been fighting with this for over a year now. I keep finding instructions that say to go to Settings and click Users. I read that this setting is available on ALL 4.2+ tablets, but not some phones. Well... it isn't on mine! I've tried rooting and installing Xposed Installer's Multi Users module thinking "aha! that oughta do it!"... but no, even then it says to go to the Settings->Users, which isn't there.
Why in the world is my menu different than everyone elses'?
It is a Samsung Galaxy Tab 3 7.0 Model number is SM-T210R Android version is 4.2.2
