I should admit that the S10e's regular fingerprint sensor wasn't 100% perfect, mostly when unlocking the phone in my hands.
I should also note that traditional capacitive fingerprint sensors don't handle wet or dirty fingers as well as the ultrasonic fingerprint sensor in the Galaxy S10.
Still, the S10e's sensor is significantly better than the S10 and S10 Plus's in-display fingerprint sensor, as you'll see below.
