Why won't the speaker on my iPhone 4S work?
I cannot get any sound from the speaker of my iPhone4s ie no music, no ringtones, no sound from apps, no voice on a phone call. If I plug in headphones, they work fine. Also the only time I get vibrate is when I switch the mute button on and off. When I adjust the volume control with no headphones in the phone, it does not show that the phone thinks headphones are still connected.
I have tried:
Upgrading to latest iOS 8
Replacing dock connector
Replacing speaker unit
Cleaning headphone socket with QT/cotton buds
I have run out of things to try. Anyone got any bright ideas?
