Phone: xiaomi 3s prime with android 6 and
Miui 8.
I use finger print lock for apps.
When open such a apps, screen shows
" couldn't read finger print. Please enter your pattern"
But i forgot my alternate pattern password.
The interesting point is am able to unlock my phone using finger print but above problem occur only with app lock.
I tried ##6484## and tested my finger print sensor. Its working fine.
