During Galaxy Note 3 and Galaxy Gear announcement, Samsung has announced that the official Android 4.3 update for Galaxy S4 and Galaxy S III will be coming next month in October. Which means that the company has decided to skip the Android 4.2.2 update and move on directly to the latest one.
The Android 4.3 update will also bring the support for Galaxy Gear smartwatch to Galaxy S4 and Galaxy S3 which are currently not supported. Currently Galaxy Gear smartwatch is only compatible with Galaxy Note III and Galaxy Note 10.1 2014 Edition. So, in october two more devices will be added to Galaxy Gear support list. There is no more details when Android 4.3 or Android 4.2.2 update will be rolling out to Galaxy Note II, but we expect it will be coming soon.
