I have noticed several times after picking up and making calls in my car via Bluetooth, that when I hang up , google music playing a song in the background. Even though I didn't start google music and I surely didn't select any music at all to play. For some reason, me making a Bluetooth phone connection is triggering it. Anyone else get this?
Ok, just figured it out. If you have rooted your phone, I don't know if this will help. My phone wasn't rooted when it was fixed.
Call Sprint Customer Care and ask them to do a "SCRTN." Essentially, this will be resetting the internal programming on the phone. It doesn't erase any information or any apps on the phone, but it did correct my problem.
