Thanks to SamMobile, Android 4.2.1 has been made available to the public, even though the official release isn’t expected until after Samsung have launched the Galaxy S IV. With a build date of 19th February, firmware I9300XXUFMB3 brings a number of enhancements sure to please Galaxy S III owners.
- Android 4.2.1 (JOP40D)
- New Android 4.2.1 Lockscreen and widgets
- Improved Ripple effect on Samsung Lockscreen
- Daydream (that nifty screensaver)
- Notification Center additions and improvements
- Voice Command
The firmware has been repackaged into an ODIN flashable firmware by SamMobile, and has been fully tested, but as always, caveat emptor – flash this, or any non-official firmware at your own risk. And since this is a pre-release version, bugs should be expected.
