the Android Wear 2.0 update is finally starting to roll out to the Asus ZenWatch 2 (at least the 1.63-inch variant).
At this time, it appears that only the 1.63-inch (49mm) version of the ZenWatch 2 is being updated to Android Wear 2.0. A smaller 45mm model was released alongside the larger 49mm one, but an exact date as to when it will be getting the AW 2.0 love is unknown.
Earlier this month, Asus said that the ZenWatch 2 would be updated to the latest Android Wear software at some point in August, so at least for the 49mm variant, the company is ahead of schedule. The ZenWatch 3 recently started getting the Android Wear 2.0 update last week, so hopefully it won’t be too much longer before the existing ZenWatch family is all up to speed.
The OTA update for Android Wear 2.0 for the 49mm ZenWatch 2 should be hitting you soon.
