OK, so the earspeaker above the screen on my phone jsut totally stopped working, I couldn't hear anything, speaker worked just fine. ANd no, it doesn't think headphones are plugged in 
so I ordered a new one, carefully installed it, then went to test it with the back cover off, it is EXTREMELY quiet, like almost not even audible. I can hear the person, so that's an improvement. So my question is, since the speaker replacement improved it, is it possible I have a bad speaker? I'm guessing the little magnet thingy is moving back and forth. Is there a chance its the comm board or flex cable? Thanks
