I have been having this issue for about 2 weeks now. If I talk on the phone, I have to put it on speakerphone just to hear the person on the other line. If my phone isn't on speakerphone, I can hear no sound at all from the other end. The person I am talking to can hear me tho. This is something I have to have fixed because I use my phone for work. I feel like I have tried everything under the sun. Any help would be greatly appreciated.
