Answer to "iPhone 7 home button not working after screen replacement"So, update…my daughter dropped her iPhone 7Plus and the screen shattered. I replaced it with the screen replacement kit from iFixit, one replaced everything worked except the home button. Neither the functionality nor the fingerprint scan worked. I took it apart and checked connections several time to no avail. About three weeks later she dropped it again and beaten down and my confidence crushed I took it to a repair kiosk in the mall and they replaced the screen and everything works now? So not really sure what fixed it or why it wasn’t working before.
