As others have stated above, in most cases it's the flex cable, if that is the case just replace. But if your like me and enjoy hot swapping parts ( very dangerous for the health of the parts being swapped) You'll simply need to restart the device. From my testing I noticed that the camera and earpiece don't register until the device is restarted. Sounds so simple... but it works every time for me!
