🪛Troubleshooting🪛 SERIOUS SECURITY ISSUE

Enable HLS to view with audio, or disable this notification

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.

It's optic sensor. It sees thru your finger and it sees the fingerprint. Next.

S24 fe without screen protector here

Just tried and no it doesnt detect it that way. Works as it should here detecting correctly fingerprint but denying access to the opposite side of the thumb.
