Updates are rolling out today for the unlocked UK GS4 and Note 3 (region code "BTU"), along with certain carrier variants. The OTA file size from 300-400MB, and brings these phones up to the latest version of Android, 4.4.2 KitKat, while adding some subtle visual tweaks, including white notification bar icons. Graphical changes aside, Samsung owners will also benefit from standard KitKat features like immersive mode, translucent notification bars in some apps, native cloud printing support and lock screen album art.
