[OFFICIAL] Samsung Galaxy S2 Android 4.1.2 Jelly Bean Update Released For i9100 Model


Owners of the Samsung Galaxy S2 i9100 version can get the update to Jelly Bean 4.1.2 which has come out in Hong Kong, Taiwan and China. It goes by the name of Android ZSLSE and the firmware comes without any branding and the Chinese language packs.

You do have to take into consideration that this isn’t custom firmware and so there are no changes to it and it doesn’t come with ClockworkMod.

The Jelly Bean 4.1 updates provides owners of the Samsung Galaxy S2 with Project Butter along with a new interface by way of TouchWiz UX. It also comes with S Cloud, a lock screen that is customisable, Smart Stay and Pop up Play. Those who make the update will also get 50GB of Dropbox storage. The update brings with it Google Now improvements, a couple of home screens and a new look to the notification bar.
