Marshmallow seems to be rolling out to a bunch of Android Wear devices lately. We first saw it come to the first gen Moto 360, then the announcement for the Huawei Watch (enabling its internal speaker), and now ASUS has joined in on the fun.
People have reported that the ASUS ZenWatch 2 is now receiving the Marshmallow update, at least to some extent. Not only will you get a bunch of fixes and improved performance, the update also adds Doze Mode and and new wrist gestures. It made a significant difference on the Moto 360, and should be just as good on the ZenWatch 2.
Head over to Settings > About > Software updates and check to see if you can pull it. If you can’t, it’s likely going to be a slow rollout and you’ll have to wait for a while until it reaches everyone.
