Touch malfunctioning with new screenWe have the same problem with my daughter's phone. The screen was replaced by Apple themselves and did not fix the issue....
"Touch ID not working after screen replacement?"に関する回答I just replaced a screen for iPhone 6 last night. The new screen came without ear piece, camera or home button. I carefully moved all these over to the new screen. After reassembled the phone the Touch ID did not work at first but the home button did. I did a “reset all settings” from the Settings and voila it all wore again. Maybe that all you need to do!
