"I've been using Norton App Lock on.my smartphone for years as a way protect my system settings menus. I recently upgraded from a Samsung Galaxy Note 8 to a Note 10+. On the new phone, the lock doesn't work correctly on system settings. When I open settings, the password prompt shows up for a second, then the the system settings appear on top, allowing full access to all my settings. When I colse settings, THEN app lock appears looking for a password. How do I fix this?"
This is an ongoing issue, and for some stupid reason, the thread was closed.
I am also having this issue, where instead of my apps being locked with an image of the pattern unlock or the fingerprint sensor, the screen darkens and a fingerprint shows with a cancel button above it. By clicking "cancel", I am allowed full access to the app. Not particularly useful when I'm accessing the settings app.
Someone suggested Samsung's software possibly being the issue, but if that were the case, would it not do the same on every app?
Let's find a solution to this issue WITHOUT closing the thread beforehand.
Thanks in advance,
For reference, below is what appears when I tap on Settings:
and this is what appears when you back out of the app:
