Coming on the heels of a leaked build of Android 4.1.2 for the Samsung Galaxy SIII (S3), the folks over at SamMobile have published a leak of the software for the Galaxy SII (S2) as well. The Galaxy S2 just picked up ICS starting in April, and now its a bit of a surprise that we may see an official update to Jelly Bean as well.
The firmware is supposedly quite stable, and seems to pack nearly all of the features that are coming to other Samsung devices with Android 4.1 -- Google Now, Project Butter, Smart Stay and new notifications are all on-board. One thing missing will be multi-view window management, which isn't surprising considering the lower resolution of the S2's display when compared to other recent 720x1280 devices.
The firmware, which is software version I9300XXLSJ and Android build JZO54K, is available for willing participants now. You can take a look at the source link below if you're ready to get your hands on it.
