Android 4.1 Jelly Bean was just announced at the Google I/O a couple of days ago. Samsung Galaxy S III, HTC One X and other such high-end Android phones should have got the first Android 4.1 preview release officially, but they didn’t. The preview release of Android 4.1 was announced just for the devices shown/demonstrated at the Google I/O i.e. Galaxy Nexus, Nexus 7 and Motorola XOOM will be one of the first Android devices to get their hands on the Jelly Bean.

Thanks to the super awesome Android community, the Android 4.1 ROM is already available now on the Samsung Galaxy S3. Faryaab, one of our favourite developers  on XDA, is the one to bring Android 4.1 Jelly Bean to the Samsung Galaxy S III first.
