The volume down button on my iPhone 5 is not working all of a sudden. I tried toggling between the volume up and down buttons, as some have suggested but it's not working. Sometimes I can get it to work by bending the phone a bit, which I really hate doing. When I had an iPhone 4 it had the home button issue, now my iPhone 5 has the volume down issue. Searching online it seems I'm not alone. My iPhone is outside the warranty period so Apple won't help me and replacing the volume buttons looks complicated, I could do it but hate messing with tiny parts. Does anyone have a real fix for this issue and know what causes it?
