Hi everyone.
I unlocked bootloader last monday on my redmi note 4 (mido), and installed twrp, your latest build and supersu right away. Everything is working like a charm, as expected.
But I have just realized that the fingerprint scanner unlocks my device with any finger (or the tip of my nose, or the tip of... whatever) NOT HAVING SET IT UP.
If I set it up, it unlocks the device ONLY with the scanned finger. If I delete the fingerprint and disable it, it unlocks the device once again with any finger.
Can someone please check and confirm the issue?
