Samsung rolling out Android 4.1.2 update for the legendary Galaxy S II40
Thankfully, this update will bring the new TouchWiz Nature UI to the GS II. Until now, the handset was stuck with Samsung's old version of TouchWiz, which was much less appealing. The new software will not only look considerably better, but will also introduce some cool features like Smart Stay - the ability of the front-facing camera to detect if you are looking at the screen in order to determine whether to allow the handset to go to sleep mode or keep the display on.
Another major benefit of the Jelly Bean update will be Project Butter - a set of performance improvements that will make the interface noticeably faster and smoother.
