Understanding iPhone Home Buttons

     Today, i'd like to discuss the sometimes confusing intricacies of various iPhone home buttons. Since the inception of the iPhone in 2007, Apple has made various innovations when it comes to the signature way to go back with their iPhones - the home button that brings you back no matter where you are. In particular, we can see two points of evolution in iPhone buttons; with the iPhone 5S and the iPhone 7. To simply state, all iPhones after iPhone 5S sport a TouchID sensor into it's button. Any previous model iPhones before iPhone 5S (includes 5C) can have their home buttons replaced with full functionality. However, starting from the iPhone 5S, the inclusion of the TouchID sensor means that any replacement buttons by anybody not named Apple will lose the TouchID functionality. However, the home button itself will work. A notable exception to this where the second point of evolution begins with the introduction of the iPhone 7 series, where the "button" itself is no longer mechanical (that is, no physical switch underneath the button). Instead, the newer Haptic Engine will mimic the feel of a button through a vibration motor. So for iPhones after the iPhone 7, home button replacements will be purely cosmetic, which is an important distinction to make. There will be no home button functionality of any kind with the iPhone 7 and later series with a replacement button. Indeed, the rules that apply for the iPhone 6/6S line with the home button also applies to any iPad with built in TouchID as of early 2018.
     FaceID as introduced in the iPhone X is going to change this going forward. However, FaceID is currently not a standard feature of lower end iPhones but will probably be implemented in Apple's lineup to be introduced in 2018. FaceID is controlled by an array of sensors near the the top chassis which, unfortunately like TouchID, is paired with the phone it came with. This means, like TouchID, FaceID replacement (sensors and front camera system) will void the FaceID functionality. Therefore, the same principles that apply to TouchID will also apply to Face-ID in the future. With all that being said, replacing the FaceID sensors does not mean losing front camera functionality, as the front camera system will still work as intended with a replacement part.
