I realize this is annoying to you but your response to someone trying to help you was rude.
I also don't see anywhere other than the lock screen settings to manage your security settings. Mine also works like your friends, seemingly by default. The only thing I can suggest is to change the security to swipe and then back to fingerprint. Maybe it's some kind of glitch you found.

What I'm asking seems harder to find then a noob trying to root his phone. It is frustrating. It's a basic feature and I'd love to have it
