In case you want to check out what's in store with the Android 4.4 KitKat update for your trusted phablet, take a peak at the video below, which walks you through the new features and alterations in the interface. The guy rightfully concludes that the new Magazine UX, as found on Samsung's PRO tablets of late, or whatever it equivalent will be for its phones, is not going to appear on your Note 3 with the KitKat update, as it is probably meant for the new crop of flagships from Samsung, like the Galaxy S5.
There are subtle UI changes, though, like the transparent status bar and white icons there, brought about by the stock KitKat. As for new features, some are also the ones that Android 4.4 brings, like the ability to chose your default launcher from Settings, including third party ones, or choose your default messaging app to be Hangouts, and so on.
If you fire up the music player now, you will get full screen album art on the lock screen, similar to the Nexus 5, and also the default keyboard stocks a bunch of emoji emoticons. Google's Project Svelte has brought on a number of improvements under the hood, too, that make the Note 3 with KitKat feel a lot faster than before, and that's perhaps one of the biggest changes you'll notice right away when the update hits your phablet.
