I am having a similar issue with my phone. I can't hear other people when I try to use the ear speaker, however they can hear me talking. My speaker phone works fine. On top of this, my front camera isn't functioning, as it won't open and causes the app to freeze. I ordered a new front camera flex cable, as this is what I diagnosed the issue to be. I put another screen (that has a different flex cable assembly) onto my logic board and the earpiece and camera worked fine. To be sure, I even put my ear speaker into this different assembly and it worked on my phone. I get the parts later this week, and will post again with the results of my repair.
