Touch ID fails, double tap works
After I replaced the screen (screen only) on my iPhone 6S, the Touch ID fails - even though the double tap for one-handed mode works.
I already transfered the small conductive plate beneath the connector (like described in Touch ID not working after screen replacement?) and took everything apart and reassemled it plus did a factory reset and disconnected the battery.
I was very gently while transferring the home button to the new screen - there is absolutely no optical damage.
What would be the next, you would try?
Could it be a problem, that I used the phone for testing purposes with another display and home button for some time?
Thanks for your help in advance.
Es esta una buena pregunta?
