So my wife just tells me (5 days after the last day I have to return my phone) that lately the sound quality when I call her is terrible. She has trouble hearing me and mainly hears a bunch of background noise while my voice is kind of faint. My signal strength doesn't seem to make much of a difference. On my end calls sound great. Just trying to see if anyone else has had any complaints. She claims it was better before. Not sure what's going on but i'd hate to think this phone sounds terrible to the people I am calling. Thanks.
