Google is concerned about security for all mobile devices running Android; the same can be said for its smartwatches on the Android Wear platform. To this end, Google has started pushing out an update in the last few days that brings smartwatches such as the Sony Smartwatch 3, 2nd-gen. Moto 360, LG G Watch R, and LG Watch Urbane. The Android Wear update brings the build number to M1D63G and ushers in the July 2016 Security patch.
The Android Wear update started rolling out 5 days ago. If you haven't been prompted yet, head on over to the software update settings on your Android Wear app on your smartphone and follow the instructions on-screen. Let us know that you received the update or are still waiting for it.
