hi. against my better judgement, I upgraded to marshmallow yesterday 6/29. Since the upgrade, the bluetooth hands-free connection between my phone and car no longer works. I rebooted my phone and I reset the car-to-phone connection. The bluetooth is on, then drops, then on, then drops.... How to fix it? Better yet - how to downgrade back to the previous version until android pushes a less buggy version? Thanks
