I purchased my Droid on January 1, 2010, so it is still very new. After 2 weeks of using it, I had an experience where I received a phone call and could hear the person on the other end of the line, but he could not hear me (as if I were muted). However, I found when I pressed the "speaker" button, I could communicate with him normally. When I turned the "speaker" off, it was as if I had muted myself again.
I had no issues with this again until today, when the problem seemed to get worse. My girlfriend called me and I couldn't hear her at all and she couldn't hear me. However, when I pressed the "speaker" on, we could communicate normally. When I turned "speaker" off, we could no longer hear each other. We hung up and I called her back and everything worked fine again.
Anyone else having issues like this? Should I take the phone back to the Verizon store to get it replaced?
