Earlier this week, reports hit the Web that the Android 4.2.2 Jelly Bean update for the Samsung Galaxy S3 handsets would land in the third quarter of this year. However, no one expected that the Android 4.2.2 Jelly Bean update will become available for the Galaxy S3 devices so early.

Galaxy S3 owners can now run the Android 4.2.2 Jelly Bean firmware, but the firmware is not an official release as it is a leaked version.

SamMobile published an exclusive report about the leaked version of the firmware and posted a video accompanying the report that shows Android 4.2.2 Jelly Bean running on a Galaxy S3 handset.

The leaked version comes with many new and exciting features including those found in the Galaxy S4.

Here is the list of new features:
