Have had my Razr HD for two years with no problem. Last couple of weeks callers (or callee's) have complained either they could not hear me or static was too loud. Called my sister earlier tonight 4 times. She answered the phone and could not hear me but I heard her clearly. Had 4 bars on my 4G. Picked up my wife's phone while sitting in the same location and call went through and we could hear each other perfectly. This problem is getting worse. Other than a soft reboot (which didn't help) I haven't tried anything else. Any suggestions would be appreciated. Just keep them simple ... thanks.
