Android 4.4.2 KitKat Leaked Firmware for Galaxy S4 LTE GT-I9505


The rumors were already there and were later confirmed by Samsung too that the manufacturer has been cooking the Android KitKat confectionery behind the scenes and is planning to serve it by the end of January or early February. The latest leaked firmware from Samsung can be seen as a confirmation to all that we had been hearing so far.

Sammobile has released the leaked version of Android 4.4.2 KitKat firmware for the LTE variant of the Galaxy S4. As for the performance of the firmware, it is very stable and it is another indication that the official release is just round the corner. However,  before the official firmware begins rolling out,  the user of this phone can feel themselves lucky to have the luxury of enjoying the TW-KitKat combo before the owners of any other Galaxy device.

4.4.2 is the latest version of Android currently and having updated your Galaxy S4 to it, you’ll be able to experience the new improvements and features integrated in Samsung’s TouchWiz user interface. Though the new KitKat based firmware with build version I9505XXUFNA1 does not bring any significant graphical changes to the Galaxy S4’s UI, there is one great change that shows itself at the first glance, and that is the new transparent status bar and the whitened icons on it. Another strikingly new thing is the faster user experience. You will also see a camera shortcut on the lockscreen now. Besides, there are several other system based tweaks and optimizations for better performance.
