So I just received my iPhone 5 from Verizon (32 GB White) and I am noticing that the Home button is not as responsive as it was on the 4S. Namely, I have to push it hard just to get it to work, and half the time Siri or double-click won't work. Right now I'm trying to decide if (a) it's a hardware defect or (b) a software defect. And also whether to take it to Verizon or Apple for service. Anyone else having this problem? Would it be worth an exchange? Otherwise the phone is flawless, it's only the home button that is giving me problems.
