Another device is joining the roster of Samsung phones that are compatible with the Galaxy Gear today – the AT&T Galaxy Note II is beginning to receive the Android 4.3 update from today, according to Samsung's support documents. Along with compatibility with Samsung's smartwatch, the update brings a host of new features and improvements, like faster performance, newer versions of Multi-Window (from the Note 3), Group Play, Easy Mode, etc., new camera modes and firmware, an upgraded interface, KNOX functionality, and more.
The update carries build number I317UCUBMK6, and as usual, should begin rolling out in stages from today and reach all devices in the next week or so. You'll have the option to download it over the air, upgrade via Kies, or download the firmware from our firmware section to update manually once it becomes available.
