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.

  • 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.

与其前身一样,A51还具有一个光学显示指纹扫描仪,该扫描仪位于子板上。

光学指纹传感器通过照亮手指并拍摄代表指纹的峰谷和峰谷的明暗区域的图像来工作。(有关指纹传感器技术的更多信息。)

子板可以轻松运行,并带有USB-C插头和备受欢迎的3.5毫米音频插孔。

专用的音频插孔可减少USB-C端口的磨损,这很好。不过,两个端口均已焊接到位,因此单独更换一个端口将需要焊接技能。

也就是说,此配置比单板Galaxy S10更好!如果一个或两个端口在您身上出现故障,则至少可以相对轻松地交换出这个小子板。
