After battery replacement finger print sensor stopped working

All instructions followed to replace battery with Pixel 3 XL. Fingerprint sensor cable was last connected before closing the back cover with adhesive applied. Now the phone no longer shows the Pixel Imprint option to enroll the fingerprint. Any suggestion?

Answer this question I have this problem too

Is this a good question?

Hi,The fingerprint sensor is very fragile you may have broken it during your repair.You could replace the fingerprint sensor or take it to a local repair shop for a diagnosis

Dear FIXIT:

Any suggestion to diagnose this issue? or it's safe to assume that if Pixel Imprint function/option is not showing up in Security Setting anymore then I probably had broken the Fingerprint sensor cable somehow during the battery replacement process?

Appreciate your further comments.

Hello! Did you manage to figure out this issue? I am facing the same thing after replacing my battery and daughterboard. The fingerprint sensor and its connector don't show any physical signs of being broken (but tough to say how fragile is very fragile :-D ). Did you solve the issue by replacing the fingerprint sensor? I am trying to check all the boxes before I order a replacement and go through the entire back panel adhesive extravaganza again.

Hi, same problem here. I think Ifixit should take a look because selling the batteries they should advice on how to avoid this to happen because it has happened to several people as I'm reading everywhere. In the tutorial you posted to try the official google fingerprint calibration tool which only work for pixel 6, 6 pro and 6a.
