Samsung gear 3 Frontier Bluetooth issues with pixel 2XL

I wonder if we would still be having the same problem with an Android Wear watch? I just bought my SG3 so I am going to return it for an aw watch. Probably the LG sport. I find you can do more with an aw watch then you can the SG3 if you are not using a Samsung phone anyway.

I'm curious though if there might be an app we can download which will turn off the Bluetooth to the watch automatically. I know my phone still connects as a media player to the car's Bluetooth even when the watch is linked. I wonder if I can use that as a trigger to turn off the Bluetooth to the watch. Anyone know of an app?
 
Tasker is an app that can most likely do what you need. You could tell Tasker that when the phone connects to a media player disconnect from watch. I am having similar problems with Pixel XL2, Gear S2 watch and car BT not playing nice. I have Tasker, just haven't played around with it to try and address the issue.
