Install Android 4.4.2 KitKat XXUDNA6 Firmware on Galaxy Note 3 SM-N900

As promised and planned, Samsung has started updating it’s latest phablet Galaxy Note 3’s Exynos variant to the latest and greatest version of Android, the Android 4.4.2 KitKat. The update has hit Russian(SER) region first of all through Samsung Kies and OTA, while Samsung will be cooking up the update for other regions and sending through KIES or OTA as well but this will take usual time.

The new update packs up performance enhancements, stability, bug fixes. Along with these, there are minor UI changes including the new white icons in the notification bar showing off Android 4.4.2 KitKat, a  move from Samsung’s old Gingerbread style green icons in the notification bar. Samsung has also given an option in the settings to switch between launchers, users can also choose whether they want to use Hangouts or Messaging app for SMS/MMS purposes. Rest of the changes can be tasted upon flashing this firmware. As off now, Samsung hasn’t implemented ART in Android 4.4.2 KitKat as it’s being said that ART is not yet compatible with TouchWiz, but it’s always better to wait in Samsung’s case as Samsung has always brought up the best and stable software to it’s users. We may see it in future builds of Android 4.4 KitKat.

So, to update your Galaxy Note 3 SM-N900 to this firmware, first of all connect your device to your PC and check for updates using Samsung KIES. The second option is to check for OTA update, to do so, goto Settings > General > About Device > Check for Software Updates.
