Android Wear Looks to be Getting a Name Change – Wear OS
It looks like Google is once again set to rebrand an Android named product or service to something more Google generic. In the latest beta of Google Play Services, version 12.5, references to Android Wear have been changed to Wear OS, complete with a new “W” icon and everything.
The change was first spotted in name only in the version of Play Services that came in the Android P Developer Preview. But a new beta rolled out to those in the beta channel for the app and you get the above changes when using the Nearby feature of Android.
