T-Mobile Galaxy S3 UpdateIt doesn’t happen often that a US carrier releases a big update ahead of the International model. Well, this time T-Mobile really stood up for its customers and released Android 4.3 for Galaxy S3 T999 (non-LTE). The international GT-I9300 also received the update but it was full of bugs and Samsung decided to pull it off until it is fixed.

T-Mobile started the updates on November 19 for the original Galaxy S3 with Baseband version T999TUVUEMJC. The only new features mentioned on the official T-Mobile page are Samsung Knox and Galaxy Gear support. So don’t expect something really amazing from this update. It will however make your device faster and smoother due to the new optimization implemented with Jelly Bean 4.3.

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

If you are on T-Mobile Galaxy S3 you can update in two ways:

  • Via OTA – over the air update starting with November 19
  • Via Samsung Kies

You can also check out the official T-Mobile Galaxy S3 Update page. If you managed to install the update maybe you can give us a hint on what’s new and how is it performing on your Galaxy S3.

    Beware. Once you do the update and want to sync with Kies 3.0, you will be out of luck. Kies 3.0 does not have a sync feature. Very frustrating.

What's my model number?

There are several ways to locate your model number:

Option 1
On your device, go to Settings, then "About device" and scroll down to "Model number"
Option 2
Often times you can view the model number inside the device, by removing the battery
Option 3
Using Samsung's model/serial number location tool
