Android 4.2.2 Jelly Bean leaked firmware for the Galaxy S III

We of SamMobile would like to give you the latest I9300XXUFME3 – Android 4.2.2 Jelly Bean test firmware for the Galaxy S III. Big Thanks to our insider who made this all possible.

Development on Android 4.2.2 update isn't completely done yet. We do not know if Samsung will bring the new Galaxy S4 Camera features to the Galaxy S3. We expect Samsung to do this but we are not really sure if Samsung will do this with Android 4.2.2 or with 4.3 for the Galaxy S3.

Android 4.2.2 is still under testing phase by Samsung and they will release the official final Android 4.2.2 Jelly Bean update for the Galaxy S III in June. We wanted to give Samsung's hardcore fans a sneak preview of what Samsung is up to at their dev center.

You will also find a lot more screenshots in the link below.
