How to prevent PIN access, leave only biometric access ON

[zebertrone]

In third world countries when you get robbed, thieves are asking for your PIN with a gun to your head. Some sensitive apps can be stored in the secure folder, but that can always be unlocked with PIN, even if you activate the fingerprint unlock. 

Is there a way to make it fingerprint only? So only I could ever access it, ever. 

What about the same but for the lock screen?

You can't. You have to have a pin along with biometrics. You can set a pin without biometrics though

Same applies for fingerprint

They require the pin because fingerprint readers aren't 100% reliable, or something could happen to your hands.
