Lock button unresponsive
My iPhone 5 lock button is unresponsive and very rarely works, it still is under warraty, should I call apple and ask for a replacement or if I get it serviced would I have to pay for that?
iPhone 5, iOS 6.1.4
If it's still under warranty and the problem isn't due to abuse (dropping, water damage), it will be covered by the warrnaty. Currently, Apple doesn't repair iPhone, only replaces them.
