Ok, so I just got one for nothing through a Christmas present/upgrade. I just activated it today and everyone I talk to says they hear their own voice as an echo. I did some googling and it sounds common, and the common fix is to turn the volume down. Well, I don't want to have a phone that I have to turn the volume down so low I can't hear the person I am talking to; so I am thinking of turning it in under the 30 day rule and waiting for the 5. I guess I want to know if anyone else has had this problem. Speak English please, this is my first smart phone.
