I use a Bluetooth speaker everyday to listen to music on my LG G3 vigor. Recently when ever I open my Google play music I will get an error message stating "unfortunately Bluetooth has stopped".
I'm having a similar issue with my G3. When I turn on bluetooth, it tells gives me that message that it has stopped. It seems to be only on Google Play Music, because bluetooth works fine when I use my OBD2 scanner on Torque.
