I have Motorola Google Nexus 6, android version 6.0.1. I use Bluetooth often with it. I transferred a music file from my PC to my smartphone via Bluetooth. Since then, many times, google play music has started to play this file many times and I had to stop it. I finally deleted this file, but now Google Play music is starting an audio file recorded on the app "Call recorder". What should I do to stop that?
