We are expecting an upcoming update to Android 4.1 Jelly Bean for the Samsung Galaxy S3, but until now no details on the changes have come to light. It seems the guys from AndroidMX.net have managed to get their hands in an official ROM and recorded a cool video showing it off.

The video does happen to be in Spanish, but you can get the gist of it. Check it out and sit tight, this update may be coming sooner than we think.

If only he could post the ROM on XDA....
