I recently replaced my screen on my iPhone 5. Everything was working fine, now all of the sudden my head phone jack isn't functioning. I went ahead and replaced the dock connector and it still doesn't work. I even went as far as switching my logic board out from my phone into my girlfriends iphone 5 and it the headphone jack still doesn't work. I put her logic board back into her phone and the head phone jack works fine. Is my logic board the culprit? I still have yet to restore my device because I have so much data to back up.
