My problem seems to be quite the opposite from this one. The latest upgrade had the note Fixed an issue where fingerprint haptics were not functioning correctly. But since then, my phone no longer vibrates on unlock.
Unlock still works, but I’m not getting any haptic feedback anymore (used to be on successful unlock as well as not recognizing my finger).
I found that enabling “Touch feedback” in the “Use vibrations & haptics” section also re-enabled unlock-vibration, but I don’t want general touch feedback, I only want it on unlock as it used to be.
