Although users of the Samsung Galaxy S3 are yet to receive the Android 4.2.2 Jelly Bean firmware update, a custom ROM based on the firmware has made it possible for the owners of the T-Mobile variant of the Galaxy S3 to experience the new Jelly Bean version even before the official roll out.
According to a Team Android report, the custom ROM called LiquidSmooth allows users to experience the stock Android, along with other mods and features.
