After my Oreo update, everytime when there is a bluetooth connection, we get a new icon on the notification bar. If you swipe down, you can see what device it's connected to, and you can switch between that device and your local phone. Well, now when I turn on my car, the bluetooth connects automatically and plays music in my car which is good. However, after a few seconds (or a couple of minutes), it would automatically switch to my local phone. I would then have to go into my phone (while driving) and manually switch it back to my car. Is this a bug? If not, how do I set it to keep it connected to my car?
