Samsung Galaxy S3 can now be installed with Android 4.2.2 Jelly Bean update.

The latest official update released by Samsung for the Galaxy S3 with model number SGH-i747 was the Android 4.1 Jelly Bean. And even though Android 4.2.2 Jelly Bean is already out, the device has not received its much awaited official firmware update yet.

However, a CyanogenMod ROM is now available for Samsung Galaxy S3 SGH i74, thanks to Android developers. If you own the AT&T version of Samsung Galaxy S3 and you are already tired of waiting for the official software update, you can opt to install Android 4.3 Jelly Bean on your device through the CM10.1 ROM.

The CM10.1 firmware for the Android 4.2.2 Jelly Bean update is still under a nightly build process, meaning there is a high chance you could come across performance issues and problems. Also, since it is unofficial, it is highly advised that users who decide to install Android 4.2.2 Jelly Bean update should take serious precautions as any mistake can cause serious damage or hard-brick to the device.

The CM10.1 ROM is compatible with the international version of Samsung Galaxy S3.
