Just came from android and upgraded to a 4S. Love everything about the phone except that I get a consistent echo of myself when on a phone call. The other person doesn't hear an echo nor do they echo on my end but when I am speaking I can hear my own voice through the earpiece. It's almost like my voice is being slightly amplified and is very annoying. I'm just wondering if anyone else has experienced this and whether I should go to the genius bar to have this looked at or is this a software issue that will be fixed? Thanks for any help. Don't know if it matters but I am on Verizon.
