My iPhone 7 home button 3D Touch and Touch ID are not working. The screen isn’t even cracked at all but the phone fell a couple of times . It’s always showing unable to activate Touch ID . The touchscreen is working perfectly but 3D Touch isn’t
have you tried setting it up again in the settings? if your still having a problem then try check for any updates or resetting the phone before you attempt to open it up. It may be that something is dislodged inside or damaged.
