I did an upgrade on my phone and now when i make calls or receive calls i have a headset icon on my screen above the time of call and i cant hear the other person and they cant hear me. I just went out to my car and put my headset on the phone and now i can hear the other person on the other end. I called verizon and they couldnt help me said to downgrade the software? Before i make ANOTHER trip (about a dozen since i bought the phone) to the store does anyone have any advice
