My wife dropped her iPhone 8 and there was no visible damage but the home button stopped working. I tired a soft reset, hard reset, factory reset, and firmware update. These did not work, so I replaced the home button with no results. So I tried replacing the entire screen along with a home button that I knew worked from use on another phone. Nothing is working and it is becoming extremely frustrating. Is there another part that I need to replace? Maybe the charing port assembly? (some call it the dock assembly?)
Firstly you cannot change a home button on the iPhone 8. It will not work at all. Try putting the original home button on your new screen if you haven’t already. If this also fails you will need to take it to apple if you want your touch ID back or you could purchase a (Universal home button) it will work the same as an original one but without the touch ID.
