Unless she holds the phone about an inch or so from her cheek her voice would come through completely muffled. It sounded like she was wrapping it in a towel and sitting on it while talking. She couldn't hold it betwean her cheek and shoulder while holding the baby, etc. It's happened to 2/4 phones. First one started about 5 months after she got it, and got warranty replacement. Second one had unresponsive screen so was replaced, and the third one almost immediately had the mic issue, and was eventually replaced - the first CS rep said that there was nothing wrong, as long as it works one way its fine. Needless to say I got his manager who replaced it.
