It looks like the Android 4.4.2 KitKat update for the Samsumg Galaxy S4 is almost ready for release. A test firmware for the handset has been leaked and is found to be pretty much stable, except for some minor glitches.
Labeled I9505XXUFNA1, this test firmware shows some changes—mostly minor—to the user interface, including the change from green to white for status icons and better keyboard layout in landscape orientation. Overall performance, gesture typing, and benchmark scores have also been observed to have slight improvements. Finally, there’s now a camera shortcut from the lockscreen.
If you can’t wait for the official update (ETA this coming February/March) to roll out, the source of this leak—SamMobile—has the firmware file available on their site for anyone to download and try on their Galaxy S4. As always, we can’t be held responsible if your phone becomes as useless as a fifth wheel.
