The owners of Samsung galaxy s3 starts reviving the official android 4.1 Jelly Bean. Samsung has released its Android 4.1 kernel source, and other open-source bits for the device. The code isn’t directly useful to regular Galaxy S3 owners but it should help community developers get more stable custom ROMs for the device.
This is undoubtedly great news for I9300 owners, some of the responses to this release seem to suggest that it isn’t particularly polished for an official release and contains many of the bugs present in the last leaked version. The software update includes the improvements from the latest version of Android like project butter , Google now, new settings tray and two home screen modes, etc.
