My headphones are only working on one side. Before they were working only when I rotate the cable above jack, but now that doesn't work anymore. Pls help!
Based on your description, I would guess one cable came loose inside the jack. You could try to re solder it. As stated, this is only a guess, since you don't tell us what earphones/headphones you have, or what device they connect to.
those headphones cable are so tiny it is realy hard to solder them your boetter to look for a new one if your not sure you will be able to fix them also on twisting you might start to broke the other .
