What should I do if my fingerprint unlock function works slowly or fails?
a) Pattern, PIN or Password security unlocking is required after the device restarts. Fingerprint unlock does not function at this point but it will work again after unlocking using another method.
b) Make sure there are no stains such as water or sweat on the fingerprint sensor. If there are, wipe the surface and try again.
c) Try to re-enter your fingerprint to your device by accessing “Settings”->“Security & biometrics”->“Fingerprint”->confirm your pattern/PIN/Password security lock->“Add fingerprint”.
d) Try to reset or update your device. (Refer to “How can I perform a factory reset on my device in the Back Up & Reset module” & “How can I upgrade my device in the Basic Settings module”).
