So the Google guys made Android Jelly Bean official during the Google I/O 2012 event, and we now know that Jelly Bean is Android 4.1, and event attendees where the first to get to grips with a preview version of the new Jelly Bean operating system on the Google Nexus smartphone that were handed out to attendees.

Thus what we have for our readers viewing consideration below is a video of Android Jelly Bean running on the Google Nexus, which comes our way courtesy of the guys over at Android Central, who deliver a comparison between two Google Nexus handsets, one running the preview version of Android 4.1 and the other running Android Ice Cream Sandwich so you can see the differences.

Apparently there are quite a few new improvements with Android Jelly Bean, which are basically based around making the Android experience more responsive to touch and slicker, and getting rid of any lag, and there’s a few treats with expanded notification functionality.

The first difference a user will notice is with the lock screen, although you still get the scrolling effect there is a new option, which is for Google Now that delivers location based info.

Anyway I am fairly sure you don’t want me to go through what Jelly Bean brings, but would much rather head on down to hit that play button so your can check out the new Android operating system running on the Google Nexus smartphone for yourself, so get to it and enjoy.
