Simple fix for headphone issue
So today I went to play some music on my iPhone 5 and could not hear anything coming out the speakers despite having the volume cranked. I didn't have headphones plugged in yet when adjusting the volume it showed clearly the headphone volume on the screen.
To fix this issue I took the end off a Q-tip and left a small bit of cotton, enough to clean the connectors inside the 3.5mm headphone jack. After inserting and spinning the head of the q-tip inside the jack hole I removed the q-tip to discover a large amount of lint and small bits of dirt had collected on the end.
Success! The issue has been resolved!
