Good morning, Galaxy S III users. Want to start off your week with a spiffy new software build? Then the folks at SamMobile are happy to oblige. They've got their hot hands on a leaked build of the Android 4.2.2 (JDQ39) update for the S III, packing the standard Jelly Bean 4.2 upgrades and more than a few features back-ported from the newer Galaxy S4. The flashable ROM posted to the site isn't exactly official - it's cobbled together from dumped files - but flashing it via Samsung's Odin software won't void your warranty.
Some of the features already spotted in the leaked ROM include the lockscreen, driving mode, Voice Controls, an updated Settings app, gallery, S-Voice, new screen modes, and a bunch of other software and visual tweaks from the TouchWiz build first seen on the Galaxy S4, as well as a host of new settings and the Smart Watch widget.
