Samsung Galaxy tab 3 8.0 and the galaxy tab 10.1 come with Android 4.2.2 Jelly bean OS installed, but unusually both the tablets do not come with the stock features of the 4.2 version. For instance Samsung chopped off the multi user capabilities from their final software for these devices.
However to correct this, they will be adding the multi user functionality on both of these tablets via the upcoming updates for these devices. According to some pictures of the test firmware, the multi user feature would be made available on Tab 3 8.0 and Tab 10.1.
The latest firmware would allow you to share your tablets with others without worrying about your personalization and also privacy won’t be at stake. There is no confirmation as whether this firmware would be arriving, and also whether the new firmware would be having any other tweak or not.
