Sorry that I don't have a pic of the damage. There is a row of resistors on the right side of the connector on the circuit board for the front camera/ear speaker/proximity/light sensor flex cable. If you are having this issue examine that area under a microscope. If you see a missing resistor (you'll see a blank space in the row of resistors and solder connections that clearly look like something was broken off) then that is causing the problem. I'm not so great and bridging space between the solder points with solder. It can be done. Out of many attempts I've been able to do it once after one of my assistants broke one on one of our shop tester phones.
