Samsung’s new Galaxy S10 phones feel great to hold and to use, and you can pick from a library of features to explain why that is. Having handled all three of the new S10s unveiled today, I’d say my favorite thing about them is the new in-display, ultrasonic fingerprint sensor. It lets Samsung combine the gorgeous all-display screen with a clean design on the rear and the convenience of fingerprint authentication on the front of the device.
