I have bought the replacement home button for my iphone 7, my touch ID sensor does not work. I know touch ID functionality will not work but this button should function as a normal home button. I restored the phone after the replacement and the button does not work. I tried unplugging the cable and plugging back in and still not working. did I get a faulty home button or am I missing something?
Before you send the home button back I would check the home button flex coming from the screen to the logic board. Check it under magnification especially at the 90 degree bend and look for a small tear. This is the most common reason the iPhone 7 home button fails after removing the screen.
Some replacement buttons are not compatible with the 7 and above. Where did you source your replacement from?
