AT&T Samsung Galaxy S3 updated to official Android 4.1.2 JZO54K OTA firmware

While the Nexus devices are receiving the latest Android 4.3 JB update, AT&T has only managed to release the Android 4.1.2 Jelly Bean OTA Update for the Galaxy S3 today. Yes, that is true, the AT&T SGS3 device is being updated right now with the Jelly Bean 4.1.2 JZO54K firmware.

The new firmware update will bring for the first time a OTA Update for AT&T Galaxy S3. There is no official changelog available, but you can expect the JZO54K OTA Update to add stability and battery life tweakes, new features such as an improved Google Now, multi-window support by Samsung. There are tons of other new things installed by this update.

Android 4.1.2 Jelly Bean JZO54K OTA Update for AT&T Galaxy S3 comes via OTA and it measures 220MB in size, which means that it should bring several key new features and functions for your device. The update is being pushed directly to your phone’s notification panel and you simply click it to start the download and update process. It would be best for you to download the JZO54K firwmare update via Wi-Fi connection, as you wouldn’t want to go over the mobile data limit.

Also, if you didn’t get the update until now on your AT&T Galaxy S3, then you can open Settings menu and use the System Updates menu to scan for new OTA Update builds. Alternatively, you can choose to connect your smartphone with your PC and use Samsung KIES software.

The update will only be pushed to AT&T Samsung Galaxy S3 phones that are running stock Android 4.1.1 ROMs. So, you shouldn’t wait for any updates to be available for devices that are running on custom ROMs.

The release of Android 4.1.2 Jelly Bean update for your device might be the first of many to come this year. AT&T is expected to update the Galaxy S3 to Android 4.2.2 in the following months and then we can hope that the official Android 4.3 build will reach it until 2013 ends.

    Got the notification, but boy is it taking FOREVER to download! At 36% at the moment, it’s been about 1 hour. Servers are probably overworked?

    • Bao Le

      Yes, and mine is stalled at 40% and i can’t not continue again. Maybe have to wait until the next day.

  • KTom

    Took 3 hr’s on wifi yesterday but got it

  • Matt

    Didn’t take too long to download considering the size, probably an hour, another 20 minutes before I noticed the install was finished. I’ve only found a couple of new features. One being the ability to screen cap a video while playing without having to stop and screen shot it. There are multiple new pieces of bloatware from AT&T plus a new program from Samsung called group play. Also burst shot camera mode can be accessed just by holding the shutter button, no need to set the camera to burst now.
