I have an extremely strange issue.. 

 

My microphone does not work ONLY during phone calls. When I connect my LG Optimus G to any other bluetooth device it works perfect. I can use google voice commands without issues while connected to my stereo, but when my phone connects to a call, the bluetooth microphone stops working. This started about 2 months ago and I can't seem to figure it out. Does anyone else have this issue, Pioneer has not been helpful to me since I'm out of warranty.
