Best answer: Yes, the Galaxy S10's under-screen fingerprint sensor should work with any plastic screen protector, but if you want to use a tempered glass protector, you'll need to buy one that's been certified by Samsung.

Why only one tempered glass screen protector works with the Galaxy S10's fingerprint sensor right now

In case you didn't realize it, the Samsung Galaxy S10 and Galaxy S10+ have a fingerprint sensor beneath the display. This allows you to unlock your phone by placing your thumb on the lower portion of the display instead of having to reach around the back where the standard fingerprint sensor has been the past couple of years.

You can't use any old screen protector for the Galaxy S10.

This is extremely cool technology, but because of the way it works it can cause issues with some screen protectors. The exact technology in play is Qualcomm's ultrasonic fingerprint reader. It uses sound pressure waves to read the 3D surface area of your finger, giving you a more technologically convenient and secure biometric security option than the previous scanner.

Those sound waves are a big problem when it comes to tempered glass screen protectors because if there are any gaps between your screen protector and your display, the ultrasonic waves can't get an accurate reading. Although your regular tempered glass screen protector appears to be in direct contact with the display, the adhesive used to keep it all together creates a very thin gap that is just thin enough to throw off the Galaxy S10's ultrasonic scanner.

Right now, there is one option right now for a compatible tempered glass protector. The Whitestone Dome Glass screen protector is made in a way that allows it to work perfectly fine with the Galaxy S10's fingerprint scanner. This is because it uses a patent-pending liquid adhesive called LOCA (Liquid Optically Clear Adhesive) over the full surface area that minimizes the amount of air between the screen protector and your display, giving those sound waves enough room to read the entirety of your fingerprint.

There are other nice reasons to go for Whitestone's Dome Glass. We like its installation kit, as it makes it laughably easy to install the screen protector without developing air bubbles. That liquid adhesive it uses can also supposedly fix minor scratches and cracks as it settles into the crevices. That gives it added value for those who maybe waited a bit too long to protect their phone.

Dome Glass is not the cheapest screen protector in the world with a $50 price tag for just one in the box, but if you want the Galaxy S10's fingerprint features without settling for lesser technology, that's your bill.

You can still use plastic screen protectors with the Galaxy S10

If you're not digging the Whitestone Dome Glass protector and it's exorbitant price tag, you should go for a plastic screen protector instead. Plastic screen protectors work perfectly fine with the Galaxy S10's ultrasonic fingerprint sensor. In fact, Samsung pre-installs a basic plastic screen protector on every unit.

There are a couple of downsides going this route. Namely, you are more prone to the screen protector scratching and wearing down over time since plastic isn't as durable as tempered glass. The blemishes this wear and tear produce will make your viewing experience considerably worse.

Installation of film screen protectors can also be a bit harder because you really have to work to get that thing on there perfectly without any air bubbles. Lastly, depending on the quality of the screen protector, it may not feel as natural to touch as tempered glass options, and some can even interfere with touchscreen performance.

The good news is that plastic screen protectors are dirt cheap, so if you need to replace one down the line then it should be no skin off your back. This 3-pack of Qoosea screen protectors costs just $7 and should offer everything you need.
