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.
  • 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.

Al igual que su predecesor, el A51 también cuenta con un escáner óptico de huellas dactilares en pantalla que se coloca cerca de la placa hija.

Los sensores ópticos de huellas digitales funcionan iluminando el dedo y tomando una imagen de las áreas brillantes y oscuras que representan las crestas y valles de la huella. (Más sobre la tecnología de los sensores de huellas digitales).

La placa hija sale sin problemas y saca a la luz el enchufe USB-C y el querido enchufe de audio de 3.5 mm.

Un conector de audio dedicado reduce el desgaste del puerto USB-C, lo cual es bueno. Ambos puertos están soldados en su lugar, así que reemplazar uno individualmente requerirá habilidades de soldadura.

Dicho esto, ¡esta configuración es mejor que la del Galaxy S10 de una sola placa! Al menos esta pequeña placa secundaria puede ser cambiada con relativa facilidad si uno o ambos puertos fallan.
