Not sure what my problem is but this is the 4th droid maxx that I have gone through now where the microphone on the phone will all of the sudden stop working. If I use bluetooth or a headphones with a mic it works just fine but if I am trying to just use my handset no one can here me. I had thought that it had something to do with my headphones that I was using but I was using the handset and after a phone call it all of the sudden the next phone call that came in they could not here me. I have also tried being on bluetooth and then changing it back to the handset and that doesnt work. I dont know what to do I like the phone so much but verizon told me that i would have to switch to a different one if I wanted to replace it again.
