The three higher-end models reverse Samsung’s unpopul

  decision to put the fingerprint scanner on the back of the device. Now built into the disp

lay itself, the “ultrasonic fingerprint reader” compliments its Face Unlock feature but prom

ises more security. It doesn’t just take pictures of your fingerprint; the company says it uses machine-learning-bas

ed algorithm to read 3D fingerprints through ultrasonic sound waves.(Fingerprint data is stored only on the dev

ice itself, according to Samsung). The S10e features a capacitive fingerprint sensor on the side of the phone instead.

  Not surprisingly, Samsung is upping its camera game. The winner for the most cameras goes to the Gala

xy S10 5G, which offers a total of six, including a dual-front camera with a 3D-depth lens to handle th

ings like augmented reality. It has a quadruple rear camera with a wide, telephoto and (another) 3D depth lens.

  The S10 and S10+ feature nearly the same without the 3D depth len

s on the back. However, the S10e has single front- and dual rear-cameras in wide and ultra-wide lens.
