As it turns out, I think it was Pandora.

My phone has had issues with Pandora. When I first got the phone, Pandora wouldn't load. So I uninstalled and then reinstalled and it worked fine.

Although the problem didn't always include Pandora, it began with Pandora, and on a hunch decided to delete the app and see if I have the Bluetooth problem. I have not.

I'll give it another day and then try re-installing Pandora.

Thank you for your help. Hope this may help others.
