Install Android 7.1 Nougat on Galaxy Tab 3 via LineageOS 14.1 [T310/T311/T315]

Samsung Galaxy Tab 3 succeeded the Galaxy Tab 2 in the year 2013. Galaxy Tab 3 came in multiple variants. The 8.0 Galaxy Tab 3 came out in 3 different variants out of which 2 had the GSM support and one was the WiFi only variant. Galaxy Tab 3 T310 is the WiFi only device while the Tab 3 T311 and T315 have the GSM connectivity as well. Galaxy Tab 3 was powered up with Samsung’s in-house Exynos 4212 Dual Core CPU accompanied by Mali-400MP4 GPU and a RAM of 1.5 GB. Internal storage options were 16 and 32 GB with expandable memory slot. Galaxy Tab 3 helped Samsung to maintain its fair share in the tablet industry.

As far as the software aspects of Galaxy Tab 3 8.0 are concerned, it ran on Android 4.2.2 Jelly Bean out of the box. This device was never updated by Samsung to a higher version of Android. Users willing to update their Tab 3 to Android KitKat, Lollipop or Marshmallow had to opt for a good working custom ROM. Google has already released Android 7.1.1 Nougat and there are many Galaxy Tab 3 users who wish to get this Android firmware on their devices.

While it is not officially possible to install Android Nougat on your Galaxy Tab 3, custom ROMs are the only choice you have. The latest Lineage OS 14.1 in the shape of Android 7.1.1 Nougat is available for our beloved Tab 3. The ROM is stable, it can be kept for your daily usage. The development for this particular ROM for the Tab 3 is still active, which means we will continue to see the improvements for a while.
