When I tried to unlock my phone using fingerprint , most of the time it failed . I was asked to enter the PIN instead of being aksed to try again with fingerprint . My finger wasn't dirty nor wet . It's annoying . I have tried repairing the software , resetting the phone . But , the problem persists. Any solution , guys ? I am using Anroid Oreo now btw . I have tgis problem since Nougat . I thought updating to Oreo would help , but it doesn't .
