How does wake/sleep button work mechanically?
I replaced my iPhone 6S battery. When I got the phone back together it noticed that the sleep/wake button doesn't have it's normal mechanical action. It works, but it works if I shake the phone or barely press the button. It is like whatever normally causes the button to spring back out after pushing it in has stopped working.
What I am wondering is, is the button spring action part of the electronics or is it part of the physical button that you press? Has some little spring-type mechanism just come unseated and I just need to fix that, or do I need to buy new button electronics?
I re-opened the phone but I cannot see anything obvious there, but I don't understand how the button works mechanically.
