Update Galaxy S3 I9300 to Android
4.1.2 Jelly Bean with AOKP Milestone 1 ROM
Galaxy S3 I9300 users receive yet another Android 4.1.2 Jelly Bean update with the release of AOKP Milestone 1 ROM, thanks to the industrious Android developers. Although Android 4.2 is around the corner, there is still no word from Samsung regarding the official release of Android 4.1.2 software update for Galaxy S3.
S3 users are still constrained to the older Android 4.1.1 firmware on the stock build official ROM from Samsung. Nevertheless, it's likely that the latest Android version - Android 4.2 - will hit the AOKP custom ROM first before being released through the official channels.
