The iPhone 7 has changed the home button and like the headphone jack debacle, users are divided. Regardless of opinion if you have a iPhone 7 the home button has changed to a haptic engine known as the “Taptic Engine” which responds to touches with subtle vibrations, which actually simulates small movements although the home button itself does not move. The lack of moving parts is, in theory, less likely to break.
However, things do break occasionally. One user discovered what happens when the home button stops working with a home button notification reading, “Home Button May Need Service – In the meantime you can use the onscreen Home button below” as a temporary workaround. Yeah the home button still doesn’t work, but at least Apple is giving you another option for the time being.
Have a iPhone 6 with a broken home button? There’s a solution for you too, Enable Assistive Touch. Open Settings > General > Accessibility > Scroll down to Assistive touch and select it. Your screen should a white round button. This will serve as your onscreen home button. Tap the white round circle button, and home options will appear. You can move this button around your screen so that it is less in the way of your daily functions.
Regional Apple Support will also help you find out if the phone is under warranty, which will make the home button replacement free!
