    Isn't the calibration test just that, a test? Does it actually calibrate anything?

    I'm having fingerprint sensor issues as well. It used to work, now it generally doesn't. What's funny is if I lick my finger, it'll work. Maybe it samples DNA as well as a fingerprint? :cool::p

    Having this same problem. Fingerprint scanner working great until yesterday.
    Was not using face unlock (but I am now that the fingerprint scanner stopped working).
    Tried re-registering, clearing cache, the calibration test, but still nothing.
    I opened a support ticket too.

    I have ran into this problem today. The scanner doesn't recognize or even light up on the ambient screen. Upon pressing the power button to wake up the screen completely, it says partial fingerprint detected and doesn't work. I've tried everything suggested so far and no dice. The calibration test fails for me too at stripe rubber test with "GF_SZ_FT_ERROR_BAD_PIXEL_OVERPROOF".

    Any ideas?

    EDIT: Okay, factory reset fixed the problem but now it's having trouble recognizing my right thumb which I've been using until now. It takes 4-5 tries to unlock. All other fingers work fine. This is weird.
