On my VA3M all my WF, as well as the popular NoFrills, Crystal (I think this is enough), when the connection is disconnected in the circular watch menu, the connection availability icon continues to be displayed. The same thing happens when i turn off the bluetooth on the phone. Reboot for a short time (approximately 10 minutes) resumes the normal indication of the presence of a junction. Then, when turning on / off the bluetooth getDeviceSettings (). PhoneConnected always returns true.
One of the users of my WF describes me the same thing - the owner of VA3 with android 8.1, last FW & GCM.
