I've had my iPhone 4S for about a year, but for the past 2-3 months the sound has been going on and off ill be listening to music and I would stop but at the top it would say it's still playing but the volume adjuster wasn't at the bottom anymore and if I tried clicking the side volume buttons it wouldn't work, but in the next couple days it would start working again. Now it's been 3 days and I have no volume at all, I can still talk on the phone but can't listen to any music or watch any videos
>>> IPhone 4S sound not working?
