The ASUS ZenWatch is the latest Android Wear smartwatch to receive Android 5.1.1. In case you don’t remember, this update brought a lot of great new goods such as support for always-on apps, WiFi (the ZenWatch doesn’t have WiFi radios, though) and new hands-free gestures for navigating the user interface.
So how do you get it? Well, one way is to simply wait. You could manually check for it (Swipe Down on Watch Face > Swipe to Settings > Go to About > System Updates) but our experience tells us you might not get very far. You can also download the OTA file and flash it manually if you’re handy enough to go about doing that. By the end of it all you should be on Android 5.1.1, Android Wear version 22.214.171.1240765, and Google Play Services version 7.3.36.
Otherwise, you’ll simply have to wait until your device is tapped to receive the upgrade (which could be as soon as a day or as much as a month). Be sure to take it for a spin and let us know what you think about it once you have it loaded up!
