sgs3As frustrating as it is to receive an update so late compared to others, T-Mobile users should still be pretty excited about getting their Android 4.1.2 JB update, finally. This is quite a large update weighing 186.72 MB and it also brings in some exciting features, including Multi Window, Samsung’s feature introduced first with the Note 2 that allows you to run two apps in the same time on your device.

The update named T999UVDMD5 can be pushed on the device using Kies or OTA. If you are not receiving the Over The Air notice, then there’s no problem to check and install it manually using Samsung Kies. The update will be pushed to you only if you are currently running T999UVDLJC, otherwise just use Kies.

DID YOU KNOW: Updato offers seamless and guaranteed phone unlocking for any device, carrier and region! It's quick and easy - try it now.
