Good news to all Samsung Galaxy S3 users, the company started rolling out the official Android 4.1.2 Jelly Bean update for the international version of Samsung Galaxy S3 over-the-air.

The new Androidv4.1.2 Jelly Bean update brings some of the amazing Samsung Galaxy Note 2 features to the Galaxy S3. The build number of the Android 4.1.2 Jelly Bean update for Samsung Galaxy S3 is "JZOO54K," and it packs the highly-anticipated Multi View multitasking system, the famous method to run applications simultaneously on the same screen.

The toggles in the notifications area can now be customizes. The Android 4.1.2 Jelly Bean update for Samsung Galaxy S3 also brings the Smart Rotation function, which rotates the display depending on the viewing angle of the user. Least, but not last you will receive applications like Paper Artist or Group Cast, plus continuous input on Samsung's default keyboard, reminiscent of the Sywipe in Android 4.2 AOSP keyboard.

If the software update cannot be found in the notifications area, you can update your Samsung Galaxy S3 to Android 4.1.2 Jelly Bean JZOO54K by connecting the terminal to Kies or OTA, by manually checking for the update for the latter method. Just go to Settings > About Device > Software Update > Check for Updates and see whether the new firmware has rolled out for your device.

You should know that the Android 4.1.2 Jelly Bean update will first hit the unlocked international variants of the Samsung Galaxy S3, therefore if you purchased a carrier-branded terminal, you will still have to wait for the firmware update, but it can't be too far away.

Below is a tutorial to newbies in upgrading their Samsung Galaxy S3s manually:

  • Download the Android 4.1.2 XXELKC OTA Update file from this link.
  • Next, extract the zip content and you should get a single file that should have a '.tar' or '.tar.md5′ file extension. That's the firmware update and you shouldn't extract any further. Leave the folder on your PC desktop screen.
  • Download ODIN application from this link. That should be Odin 3 v3.04 zip file. Extract the ODIN files to the same folder as the firmware file. Now get to the next step.
  • Power off your Samsung Galaxy S3 completely by removing its battery. Re-insert the battery after 5 seconds have passed.
  • Boot your phone into Download Mode. It can be done if you press simultaneously 'volume down', 'home' and 'power' buttons. Release the buttons when the screen powers on and then press Volume Up to confirm that you wish to boot the SGS3 into Download Mode.
  • Launch ODIN3 v3.04.exe file.
  • Connect your Galaxy S3 to your computer via USB cable. Odin should display the 'added!!' alert in its message box. Get to the next step. NOTE: If this doesn't appear, then you should re-install all Samsung USB drivers and enable USB debugging option on your phone.
  • In ODIN window you have to click on 'PDA' and then browse your PC for the '.tar.md5′ file you've extracted at step 2. That's the Android 4.1.2 XXELKC firmware update file and you have to load it into ODIN.
  • Don't change any default ODIN options and make sure that 'Re-Partition' option box is not enabled, as if it is, then you need to disable it.
  • Press the 'Start' button to begin the Android 4.1.2 XXELKC update on your Galaxy S3. Do not press any other buttons and simply wait for the install process to finish.
  • After the install of the OTA 4.1.2 Jelly Bean firmware is complete, Odin will say 'PASS' and your device will restart by itself. When the SGS3 displays its Samsung boot animation logo, unplug it from your computer and then you're done.
  • Now, your device boots into its new OS and you can begin to test all of its new functions. Tell us in comments which is the best new Android 4.1.2 feature and if you like the overall performance of your phone after installing the update.

Hold your horses. You should keep in mind that the Android 4.1.2 Jelly Bean update for Samsung Galaxy S3 will roll out gradually; therefore, it will not be available all on the markets in the same time.

Moreover, if you bought a Samsung Galaxy S3 via carriers, there is a chance that the latest update will be delayed since networks usually tests the files themselves to make sure they work with any custom software tweaks before allowing the updates to reach their customers. Consumers may need to wait for days weeks or even months before this new update hits some of the carrier-branded Galaxy S3 models.
