AT&T Samsung Galaxy S3 (SGH-I747) 4.1.2 Jelly Bean I747UCDMG2 OTA Update Rolling

The Android 4.1.2 Jelly Bean update on AT&T’s Samsung Galaxy S3 (SGH-I747) has finally arrived. The new firmware version build numbers are I747UCDMG2  and recently rolled out  live via OTA (over the air). This is the ‘Premium Suite’ update that features the long-awaited ‘Multi Window’ support and other 4.1.2 stuff, and well of-course the AT&T’s default bloatwares are still present. This is an update from last December released I747UCDLK3, and it takes around 6 months before this update begins rolling. It’s not too late though, I guess! But an update is still an update.

I747UCDMG2 4.1.2 Jelly Bean:

Software update includes

  • Multi Window: You can open two different apps at the same time into two different windows on the mobile screen.
  • Auto Share Shot with NFC: By setting the camera to “Auto Share Shot” mode, you can quickly share your photos and videos by simply tapping their GALAXY S III with other NFC and S-Beam enabled devices
  • Camera features: Paper artist and best face options.
  • AT&T apps: AT&T services, Drive Mode, AT&T Locker; Family Map, Live TV, and SmartWifi have been loaded.
  • Other enhancements:  Includes calendar, SD Card, and S-Voice enhancements.

AT&T Samsung Galaxy S3 4.1.2 Update UCDMG2
AT&T Samsung Galaxy S3 Android 4.1.2 Jelly Bean Update – 31st of July 2013
  • Android version: 4.1.2
  • Baseband version: I747UCDMG2
  • Build number: JZO54K.I747UCDMG2
  • Kernel version: -3.0.31-1300972
  • Stock I747UCDMG2 Update

This update can be downloaded via OTA update (over the air), which means the release will be in stages, a first come first serve basis which mostly last to a couple of days until all Galaxy S3 devices completely covered this update. To learn more about this update just head-over to AT&T’s support page.

Those who might not root their devices can update quickly,  those who has root might ‘suffer from ‘OTA update failure’ so just make sure you have your device returned  back to stock recovery before performing a live update and/or just look for the OTA update flashable zip file which can be manually installed via  ‘Install Update’ in recovery mode. It’s not available through Kies and we will try to dump the full stock firmware from the server if they release it.  Root still works on this update and no alleged bootloader re-locked patches that blocks users from rooting. AT&T is the friendliest US network to Android community, at-least compared to others though.

Just share to us how’s your first impression about this 4.1.2 Jelly Bean update. Enjoy, and let’s all wait for the upcoming 4.3 updates which I guess may or may not happen too soon.
