Are you sure you want to drink that glass of water? Because that glass will have your fingerprints all over it. And that, apparently, is enough to crack your smartphone.

X-Lab claimed to be the first to crack an ultrasonic fingerprint sensor, along with two other common types used in smartphones: Capacitance and optical sensors.

But that claim isn’t entirely true. The ultrasonic fingerprint sensor in the Samsung Galaxy S10 was actually cracked earlier this month… by a woman in the UK who happened to purchase a £2.70 (US$3.40) screen protector on eBay. The screen protector enabled any fingerprint to unlock the phone, which didn’t exactly do wonders for Samsung’s reputation.
