I've noticed recently that when I hang up on a call, while using a blue tooth headset spotify will start playing music automatically through the headset as soon as I hang up. I am using iOS 7.1.2 and Spotify 220.127.116.11
This happens every time!
Have you checked your default play settings to make sure it's not set up somehow? Kinda odd, but worth a look.
If this solved your issue - Mark it as a solution! Twitter | LinkedIn | InstagramWhat's a Spotify Rock Star, and how do I become one?
I have this same problem and I have checked settings and reloaded app what else can I do? It is a real problem it happens every time I hangup every time.
