Samsung has released a hot new update for their Galaxy S2

If, like me you are a happy Galaxy S owner then you are about to get more happy, eh- or happier…
A pre-release of Samsung’s new JellyBean firmware 4.1.2 has just hit the net and it is smooth, real smooth. If you have a Galaxy S2 get out and test this Rom. I have been running it for a few days now and I love it. Google’s project Butter really shines here. This thing is fast, smooth as silk and has some really nice functionality built in. And most of all, it is nice to see that the S2 still has some fight left in him, and can be competitive on the market. With 4.1.2 installed my device feels like a new smooth handset. It is easily as smooth and the new quad core Tegra devices I have played with. The best is still yet to come. This is a pre-release, and is so smooth I just can’t imagine what the full release will bring. This is easily good enough as a daily driver- so read the instructions below, install it and have fun. Oh, and when the final comes, I’ll make sure you know. Below is news and details from Sammobile.

We of SamMobile would like to give you the latest I9300XXLSJ Android 4.1.2 Jelly Bean Test firmware for the Galaxy S II. I9100XXLSJ is the first ever Jelly Bean leak for the Galaxy S II and surprisingly it’s really stable as well. This TEST Firmware was leaked by Forum Member izap of XDA-Developers.
This build is very much near perfect so we believe that Samsung will actually start rolling out the Official Jelly Bean update for the Samsung Galaxy S II very soon. The day Samsung starts to roll out the official update you will be able to install the latest update through Kies or OTA update.
Some of the Enhancements in the new Jelly Bean Update:
- Buttery Smooth Performance & Great Stability (Thanks to Project Butter)
- New TouchWiz Nature UX (Same UI as of the Galaxy S III and Galaxy Note II)
- Samsung’s Cloud services
- Direct Call, Smart Stay and Pop-up Play Features
- New Widgets From the Galaxy S III
- 2 Home screen modes
- New Notifications bar
- Google Now

This is a PRE-RELEASE version so not official from KIES.
As this is a PRE-RELEASE firmware so expect some minor bugs.
