I'm using bluetooth to connect my smartphone (iphone 5, ios6) with spotify to my car audio system. Everytime i get a call while i was listening to music, the bluetooth connection crashes a few seconds after i hung up. To fix the problem, i have to go to settings -> bluetooth and deactivate it. After that i have to reactivate it and connect it again to my car.
Has anyone an idea how to fix that? Is it a generic ios problem or more a spotify problem?
