Late yesterday, Google began rolling out an update to the Android Wear companion app. Despite a sudden growth of over 2 MB in size, the app only seemed to change the text of a warning, and there were no visible changes on our watches. We knew there had to be something great hidden under the covers, and we were right. The companion app certainly has some interesting changes of its own, but it also acts as the delivery mechanism for a Wear-customized version of Google Play services, and there's a bit to talk about in there, too.
Sometimes, updates break things. That seems to be the case for some HTC owners who, upon receiving a silent update to the newest version of Google Play Services, are having trouble using apps that rely on location data. According to HTC phone users in this support thread, Google Now continually asks to turn Location Services on, location-dependent applications like Foursquare and WeatherBug don't function properly, and Maps is unable to lock onto a location.
