This week Google aims to disconnect the smartwatch from the phone - so to speak. Amongst a collection of features appearing on the newest Android Wear update, this week "phone free" functionality comes to the smartwatch. As long as your phone is online, connected with Wi-Fi or cellular data, and your smartwatch is connected to the web, they'll be able to function together. Time to leave your smartphone at home - for real, this time. Just so long as your Android Wear device can function in this way, of course.
