At the weekend I connected a usb dac and amp to the Note 3. When I made the connection it triggered the emergency assistance function on the Note 3.

This function sends a MMS message to whoever you setup in the settings. The message includes your GPS location and a Google Map link. In addition the front and rear cameras take a simultaneous photo and off everything goes. Well, you can imagine my surprise when one of my emergency contacts calls me and tells me I need a shave and could they have one of the chocolate biscuits on the table.

I realised that every time I connected the usb dac the same thing happened.  So I turned off that option and no more emergency messages.

That got me thinking about my current issue with Google Play Music, whereby it kept going silent after one or two songs but was still playing , and only fixed by pausing then pressing play. I wondered if the emergency assistance feature was clashing and low and behold it was. With emergency assistance off, Google Play Music works just fine.
