ear speaker issue

[paag1124]

I am having an intermittent issue with the small ear speaker. Sometimes when I call it makes a really weird buzzing sounds in between rings, almost like some small piece is loose and vibrating in there. I also notice it when I am talking to people who are loud on the phone. I was wondering if anyone else is experiencing the same issue. I love my new Bionic; this is the only issue I have encountered and am a little hesitant to take it back without being sure I can recreate the issue or having a better explanation of the problem. Thanks in advance for any forthcoming help.
