I am starting to wonder if this is a KitKat issue. Here is why I am I am blaming KitKat.
It started with my Verizon Moto X. This is my first KitKat device. I listen to podcast throughout the day over bluetooth headsets. I have 2 that I switch between as they need charging. What will occasionally happen is that I will power off one headset when the battery gets low and then power on the next one. Instead of passing audio to the new headset it will pass it to the (front)phone earpiece. Even shutting off the the headset will not allow it to go to the rear speaker. The audio will stay going through the earpiece speaker until I reboot the phone. I thought this was an issue with the Moto X until I loaded SlimKat 4.4.2 on my Galaxy S3 and it started doing it on this phone. I use different bluetooth headsets than on the Moto X. It never happened on the S3 when I was running JB.
Am I the only one experiencing this?
