Just yesterday we posted about Android 4.1 Jelly Bean potentially making its way to the Samsung Galaxy S III by the 29th of this month and how it was strange that no test builds have yet leaked. As luck would have it, a leaked build of Jelly Bean for the device has now appeared for the device, which is great news for anyone looking forward to Google’s latest tasty treat.
Brought to us by SamMobile (the same guys who predicted the 29th as the OTA release date) and posted to XDA by Recognized Developer Faryaab, this is test build XXDLG4 targeted at the international version of the device. While it may not be a final build, it brings the I9300 all the latest Jelly Bean features including the revamped notification bar and Google Now.
You can download and flash the build by following the instructions in the original thread. However, as mentioned in the thread, be sure to verify that you are on a stock Samsung ROM before flashing it. Otherwise, you risk bricking your device.
