How can I figure out what's wrong with my fingerprint reader on Android, specifically fairphone 6.
I would like to avoid factory resetting my system to avoid having to set up all my (payment and messaging) apps again.
Fairphone has no good documentation for debugging this, so I built my own debugging app. This indicates the hardware is fine but software is not.
