iPhone iPhone 5 lock screen camera button doesn't work

I am having problems with my iPhone 5 lock screen camera button. It is suppose to slide up and have instant use of the camera but it will not slide up. it will just bounce up and down and won't slide all the way up. I already did all the updates to iOS 6.1.4 and also a hard reset. didn't solve the problem. The phone company didn't have any solution other then get a replacement phone or wipe the phone clean and get a new one. any suggestions? I don't want to start over with all my apps thanks in advanced!
