Samsung Galaxy S3 Android 4.3 firmware leaked – build I9300XXUGMJ9

Following the Samsung Galaxy S4 and the Galaxy Note 2, Android 4.3 firmware for the Samsung Galaxy S3 has also made its way online and is available for download, unofficially of course.

This is the first Android 4.3 leak for the Galaxy S3, build version I9300XXUGMJ9, and while stable, is still a test build and will probably have a few bugs. According to SamMobile, some of the changes include a complete overhaul of the UI, making it similar to what can be seen on the Samsung Galaxy S4 and Galaxy Note 3, with the Settings app also featuring a new tabbed interface. Unfortunately, the original launcher and widgets are still being used, and Samsung Knox, which is an expected feature with the final release, is yet to be implemented in this version. Of course, since this is a test build, features and more UI changes may be available in future leaks and the final, official release.
