The S10 display assembly on the right shows off the ultrasonic fingerprint sensor that’s built into the screen. The pre-installed ones are just as easy to remove as any other film-based screen protector, but you’ll have fewer choices when it comes to replacements. Since plastic scratches more than glass, you’ll likely need to replace it at some point. The pre-installed screen protectors will work, but they’re the cheap plastic film variety. (The S10e is exempt from this since it uses an old-school capacitive sensor within the power button). The ultrasonic sensor on the S10s, however, uses sound waves to read your fingerprint, which limits the type of screen protector you can use on the phone. Optical fingerprint sensors can handle a broader range of screen protectors because the sensor can easily see through the clear film or glass to take a gander at your fingerprint.

Optical sensors look at your fingerprint, whereas the S10’s sensor actually listens for it-which is pretty slick. But the S10s use ultrasonic tech instead of the optical sensors used by others.

And since it scored a measly 3 out of 10 on our repairability scorecard, you definitely need a screen protector-and probably a case-on this phone.Īfter years of shipping phones without screen protectors, why did Samsung suddenly feel the need to install the screen protector themselves? The two new flagship Galaxies come with a fingerprint sensor built into the screen, which isn’t completely new-the OnePlus 6T and a few other phones have beaten Samsung to it. This was rather nice of Samsung to include because you can’t install just any screen protector on the S10 or S10+. The new Galaxy S10 and S10+ are now splayed out in all their glory, and before we even pried them open, we noticed an interesting new feature: pre-installed screen protectors.
