Just like its predecessor, the A51 also features an optical in-display fingerprint scanner which is placed near the daughterboard.

Optical fingerprint sensors work by illuminating the finger and taking an image of the bright and dark areas representing the ridges and valleys of the fingerprint. (More on fingerprint sensor technology.)

The daughterboard comes out without a fuss and brings the USB-C plug and the beloved 3.5 mm audio jack to light.

A dedicated audio jack reduces wear and tear on the USB-C port, which is nice. Both ports are soldered in place though, so replacing one individually will require soldering skills.

That said, this configuration is better than the single-board Galaxy S10! At least this tiny daughterboard can be swapped out with relative ease should one or both ports fail on you.
