As promised, T-Mobile has started rolling out the Nougat update to Samsung Galaxy S6 and S6 edge units on its network. The update weighs in at 1270MB for the S6 and 1290MB for the edge variant, and brings along Android OS version 7.0.
Aside from the phones, the Android 7.0 Nougat update has also started hitting T-Mobile's Samsung Galaxy Tab S2. It weighs in at 1006.80MB. Given that the roll out is OTA, it may take some time for the update to hit your device.
