Ok so I've got the iPhone 7 plus. I Understand the haptic button and adjustable three stage sensitivity, also the click speed adjustments. The thing is if i press lightly I get a soft vibrate and if I press firmly I get a harder vibrate, but I cant find anywhere that says the home button does this so thought I'd ask. It's very easily noticeable and wondered if this is the same on all iPhone 7 home buttons or an issue. Thanks.
