Hi, I have my iPhone 6 64GB Space Gray for a few days now. Today I noticed that "click" sound when I press the lock button (or sleep/wake button) is different than when I press the volume buttons. When I press the volume buttons they makes loud "click" sound and also these buttons are quite stiff. When I press the lock button it makes much more softer "click" sound and also this button seem to be little bit easier to press. Do you have similar experience with your iPhone 6 (not 6+)? Does your lock button feels little bit easier to press than volume buttons? I can't remember if this behaviour was same from the first time I use my iPhone, or it change when I used it, so I'd really like to know.
