Anybody's iPhone 5S home button really loud? I had an iPhone 5 before and it felt like a solid button. But this iPhone 5S's home button has a very audible click, especially when I let go of it after pressing it. Is this because of the way it's built with the fingerprint sensor underneath, or was I lucky enough to get a defective one? I'm also worried Apple won't exchange this if it's something as small as a louder home button click...
