I was able to use the iris lock screen option when I bought the Note 9, but eventually I choose the pattern lock type. In the meantime I installed several apps. Later on, I felt that the pattern was not that efficient, specially when I was walking, and decided to use iris lock screen type. The problem is that the option (as well as facial recognition and intelligent scan) was greyed out! I can’t even turn it on/off...
Could it be that some of the apps I installed disabled those 3 options?
It’s really annoying uninstalling and reinstalling the apps, one by one, till I find the problem.
Solved! Go to Solution.
Are you able to see the options while your device is in safe mode?
