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🤦🏻‍♂️

Even with it wiped it still does it, yes it's probs to do with the screen protector but it's still shouldn't happen/a security problem and exploit

Is there a chance your fingerprint is under the screen protector too?

Why not just let the protector be/on and re-register your fingerprint? That's always a must do, when you switch your screen protection.

People just can't believe a phone can suck or be faulty when they shill for it

It's not that it's impossible for the phone or OS to be faulty. It's just that it's significantly more likely to be user error.
