My wife's phone was being weird. She tried to make a call, but couldn't hear anything. I asked her if the volume was turned down, and i grabbed it and made a call to our house, then pressed the volume up. It said headphones above the volume bar. No headphones were plugged in though. So I looked around in her settings, and they were identical to mine on all the sound and phone settings. I made another call, and hit the speaker button, and that seemed to clear it. But it is still on speaker phone mode and not on regular mode. If I switch it back to normal, it still thinks headphones are in. I tried the reboot by holding down power and home, but it still does it. Do I need to restore it, or is there some setting I'm missing?
