The latest Android 4.4 KitKat firmware for the international Galaxy S4 (GT-I9505) was released by Sam Mobile recently.
The firmware comes with major changes like the white status bar icons, camera shortcut on the lock screen, music playback immersive mode and improved performance. Apart from those, there are also new keyboard layouts, emoji support, Home settings, default Hangouts and wireless printing option as minor changes included in the Android 4.4.2. However, it must be noted that the Samsung Galaxy S4 has not made it to the Android 4.4.2 KitKat update just yet, like the Samsung Galaxy Note 3.
