Why won't my phone register headphones?

[AC Question]

I've cleaned the jack several times, multiple different ways, pushed my headphones/aux cord in until it clicks (all the way in), tried several different headphones and aux cords, but nothing is working. Is there something I'm doing wrong?

Possibly there's a disconnect between the jack itself and the main board? I'm not sure, but that seems the most likely if you've taken all the steps you have.
