Good news to all Samsung galaxy s3 users, the international version of Samsung galaxy s3, which have been the world’s best-selling smartphone, now already received the much anticipated Android 4.1.2 Jelly Bean update over-the-air. Many major national carriers has released Android Jelly for the device, and other Carrier-branded versions like Verizon Wireless should be able to receive the update soon as Samsung is railroading updates for its devices. But some only offer an update that must completed via Samsung Kies software and is not offered over the air.

The new Android 4.12 Jelly Bean Update brings a list of amazing features now only located in Samsung Galaxy Note 2 to Samsung S3, like highly-anticipated Multi View multitasking system, Smart Rotation function , camera filters, low-light photo mode, an easy mode and so on. For some people you may find it is difficult for you to update or wait any longer. So here I will show you How to update Android 4.1 Jelly Bean on Galaxy S3 immediately.

  1. Be sure to backup your data before starting the update
  2. Make sure your battery is at least 50% charged.
  3. Make sure that you have install Kies software on the computer, and if you don't have Kies, you can download it from Samsung website.
For international version: 

If the software update didn’t popped up in the notifications area, you can update your Samsung Galaxy S3 to Android 4.1.2 Jelly Bean 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.
