The Mi 9 Cepheus 9.6.20 has been confirmed to have a bug using the fingerprint sensor to login. It will usually flash several times 3-10 times before recognizing the user if at all if the finger is not in an exact position. This happens usually on the lock screen after being off a while. The bug is intermittent, not constant. This was a bug in an earlier Xiaomi.eu release as well on MIUI 10.4. Please fix thank you.
