I have a Razr HD. Occasionally in past callers couldn't hear me, all I get is Hello, Helllo, Hello. Now the mic seems to have quit working completely. Does not make any difference if it on speaker phone, still nothing. However I did figure out when using the camcorder, it picks up sound perfectly. I tried doing a reset and nothing changed. Is there a separate mic for the camcorder? If there is can the front mic be replaced? Thanks for the wife, currently using the wifes old Iphone and I want mine back!!
