Hi, I just got my Incredible 2 weeks ago, and I've noticed that it makes a really annoying noise when I'm on the phone... Most of the time, it's an metallic style noise similar to microphone feedback. Sometimes I hear myself echo really bad too. I went back to the store with my phone and was told that it is a system issue that would be fixed soon. Not sure if the guy was right or not... but it hasn't gotten any better and is really bothering me as it is quite loud and hard to understand the other person talking at times. Any ideas if it really is a system issue, and what could I do about this?
