Balzano , via OnePlus 9 Pro , Aug 16, 2021 : So all of a sudden my fingerprint sensor started acting up. It suddenly stopped recognizing my fingers. So i remover the saved prints and redid it. But it doesn't matter because it can't find my fingerprint from locked screen or other applications. I tried rebooting the phone. Removing and adding the fingerprints again. edit; trying to add fingerprints now results in an error message.
