This only started happening a couple hours ago. But while I was on break at work I noticed my phone wasn't playing any audio, from videos to pandora to snapchat I can't hear nothing. I think it might think there's a headphone plugged in but when I tried to plug & unplug, no sound. When I do have headphones in I can hear. Also, I can't hear phone calls but when I put it on speaker I can. I tried turning the phone on & off but nothing. I don't know too much about iPhones & this is already my second one w/ insurance. I'm not trying to go to a phone repair or the apple store, or to a tmobile if I don't have to. Can anyone help me out?
