With nowhere left to turn, we boldly take our chances removing these delicate displays. Once inside the S10, we spot the new ultrasonic fingerprint-sensing getup.

Qualcomm QBT2000 Ultrasonic Fingerprint Sensor Controller

This is old tech for bats and dolphins, but a smartphone using sound to read your fingerprint is pretty cool, if we're honest. (Courtesy of Qualcomm.)

The tech may be novel, but our praise ends there. We threw just about everything we could at this little guy and it is not coming out intact.

If Samsung has any repair tips they'd like to share, we're all ears. For now, assume you're going to pay an arm and a leg for a new screen should the sensor malfunction.
