When I lock my phone using the POWER BUTTON, I can unlock it using fingerprint.
But when I use an APP to lock my phone (like WTN or Lock Screen etc.), I can only use a PIN or Password to unlock.
I see that finger print unlock is not supported in any 3rd party screen lock widgets/apps. Why is that? What makes the "Screen Off" initiated by the power button different from the "Screen Off" initiated by an app or widget?
