Weird problem. Have you tried a factory data reset?

Settings - application manager. Go to the all tab and find the settings appWhere is that feature located Almeuit?
Maybe some app is causing interference. Do a factory data reset and don't install any apps and see if the setting is thereI tried a factory reset on it once, and it allowed me to use the knock code, but when I changed it to PIN, it grayed the others out. This was maybe 2 hours after the first factory reset, I didnt even have all my apps reinstalled.
It's in the security tabYou don't need to reset. You just need to go into credentials and uncheck the apps with admin access

I don't have that option, and I've already unchecked the only box in there and rebooted.View attachment 184093
Try the steps below.
1. Go to your settings
2. Go to "apps"
3. Scroll to the left till you have it on the" All" section.
4. Find "Settings" (not the Smart Settings)
5. Tap it and hit clear cache. (pics below)
