So, I've had my phone for a couple weeks and I love all the bells and whistles and other great features that work really well, however I've had a few people complain that when they're on the the phone with me that my voice volume doesn't come in very well and that I sound either muffled or quiet or further away. I can apparently remedy the issue by connecting my bluetooth headset, and then the callers tell me that the volume level is louder and clearer. So I'm wondering if this might be a problem with the microphone itself or maybe the way that noise cancellation is being handled by the software. Since the call quality seems to be fine with the bluetooth headset, I don't believe this could be a network problem, but is there anyone else out there experiencing a similar issue at all?
