That's true. I wouldn't say the home button loudness is annoying , it's annoying when I click the button and then hear 2 or 3 clicks like it's popping back into place. When you press the button you should hear 1 main click. Not 3. I think this is an issue with others in this thread. The overall loudness isn't really that bad. Just takes getting used too.
Exactly what mine is doing. There is a click as I start to depress the button, but its not actually the switch that is making the sound, it's something else. I have to continue to press the button to activate the switch. It is annoying, and it is a defect. I will be exchanging mine next time I'm at an apple store. Also strange, sometimes it doesn't make the double click, and it's smaooth as it should always be.
As for the people who say "stop complaining", I assure you your phone isnt doing this, or you too would be ready to exchange it. And yes, for $700, my 3 week old phone better be perfect! When they highlight their product with videos that brag about tolerances and perfection, my fn switch better not sound like a cheap toy with a problem!!
