The Android 4.4 KitKat firmware for the Snapdragon 800-powered Samsung Galaxy Note 3 is already seeding in Poland and even more countries will be getting it very soon. However if you want to flash it manually you can follow my tutorial here.
Today, just a week after the Snapdragon 800 ROM became official, the Exynos 5 Octa powered Galaxy Note 3 is also tasting the sweet KitKat. The first country to get the latest Android release is Russia, but naturally, other regions will be joining the list in the next few days.
The KitKat firmware boosts the performance of the Samsung Galaxy Note 3, improves the RAM management and increase the system stability. It will also bring you monochrome status bar icons, full-screen album art on the lockscreen, plus some bug fixes. There is still no info on the battery performance, but fingers crossed it will get better as well.
