Audio only comes out of the right head phone on my iPhone 4?
I've just bought an iPhone 4 16GB off a family friend and the phone was in fully working order, I've seen it and used it. It's been restored back to factory default and now audio only comes out of 1 head phone through the audio jack? I've checked inside the jack for anything in there and I've used 4-5 pairs of head phones I know are working having used them in other devices. I've used this phone in the past with the head phones so I know it does work. I've tried doing a reset, same problem still occurs. Any idea's at all?
iPhone 4, iOS 6
