Drop down you notifications, then long press the Secure Folder notification.

Three options should pop up: “Turn off Notifications” (does not work, it’s grayed out) “Settings” “Done”

Press on “Settings” and it should open the App Notification Settings for “Android System”

You should see a few options, look for “Notification types.”

Make sure “Lock Screen” is Allowed, you should have it on by default.

There should be an option that says “Lock screen notifications,” it should say “Show content” by default.

Press that and it should give you the two option: “Show content” (should be checked by default) “Hide content”

Press “Hide content” and it should hide it everywhere, not just the lock screen.

It’s not gonna go away, but it hides what the notification is for, it should just say “Android System” and it should be a thinner notification too.

Hope this helps! 😁
