I have a question: I have just received my new Droid X about two weeks ago. When I made my first phone call, I noticed a buzzing sounds like the speaker was blown. I thought maybe the buzzing would go away but has not and it is really bothering and annoying. Here is the question part, I would like to exchange the phone for a new one because of the buzzing...would this be considered a reasonable issue for a warranty exchange? Thank You!
