Samsung Galaxy Tab 2 7.0 gets Android 4.1.2 Jelly Bean update
Currently, the software update is said to be rolling out in phases. So if you own a Galaxy Tab 2 7.0 yourself, don’t worry if you still haven’t received an upgrade notification on own device. It probably just isn’t available for those in your country yet, but it should be very soon. According to the official firmware details, the software update goes by build number JZO54K. It can be facilitated through Samsung KIES or via an over-the-air (OTA) download.
It’s best to wait until you get an official notification to upgrade before checking for the latest software on your device. In the meantime, you may prepare by making sure that your tablet is fully charged in order to avoid any hiccups during the actual upgrade process, that is once you begin.
