I have been experiencing problems with the earpiece speaker during phone calls. Randomly during a call I will hear a loud hiss as if the other person on the line were blowing into the mic on their phone. Just yesterday I bought my gf the nexus and today we were on a call and experienced the exact same issue, so I know now it isn't just my phone. This noise is extremely loud and annoying. I wonder if anyone else has had this problem and if maybe they know of a fix. Any help would be greatly appreciated, thanks all.
