Touch ID fails, double tap works

Hi everyone!

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.

The chances are the home button extension cable may be faulty on the replacement iPhone 6s screen, every screen comes with it assembled together.

Well, that's worth a try! I'll check it with the old broken display tonight. Thanks :)

Didn't work with another screen. Either the Touch ID IC is broken or ... :-(

I had a very similar situation with a iPhone 6, no Touch ID after doing a screen replacement. Checked everything and nothing was damaged, tried a another screen had the same results. The next time the customer did a IOS update it started working?!!

Yeah I had an issue like this on iPhone 5s. The customer didnt come back so I assumed the touch ID not working fixed itself.

Must have been a lucky constellation, so that apple seems to have changed something with the authentication. I'll wait for an update definitely. :D

It just started working out of the nowhere :D

Think I had a problem with my magic wand or so...
