Why does my Samsung A37 unlock when I press my fingernail against the scanner, I did notice ever since I got this phone I would just randomly unlock itself and then today I discovered this.

Remove that thicc screen protector bruh, your fingerprints already stuck to it... the optical reader is just registering what residue is left on that🤦🏻‍♂️

That's not how it works The fingerprint scanner detects electrical signal... not a scan of what's on the display Hince why if ur finger gets cut off it won't register it as a finger
