I just got my X today and notice that when I'm talking on the phone, there is a weird buzz-ish or static sound when the person is speaking (not speaker phone). I'm not sure what's causing it but it's uber annoying. My husband just got an X too and he's not having this problem. We have the same case, just different colors. I've re-booted, adjusted the volume etc, not help. Oh,and I use Verizon if that matters. Any help would be appriciated. Should I just send it back?
