PSA: Galaxy S10 fingerprint reader works best without a screen protector

Having trouble getting the in-display fingerprint sensor on your Galaxy S10 or Galaxy S10+ to recognize your fingerprint without the phone asking you to press harder? You might want to remove the stock screen protector. Every Galaxy S10 comes with a screen protector out of the box, and while the in-display fingerprint reader works Samsung’s official screen protectors, it works better without it.

Screen protectors and ultrasonic fingerprint sensors are not the perfect couple

The Galaxy S10’s ultrasonic fingerprint reader seems to have trouble working with a light touch of the finger with a screen protector installed. That’s why you should simply remove the protector if you are constantly asked to press harder despite already applying enough force. Yes, removing the screen protector might not be a good idea if you want to prevent scratches on the display. But let’s face it: Those basic screen protectors are easily scratched in a few days of regular use and can ruin the viewing experience as a result.

As for tempered glass protectors, we can’t exactly say to what extent those affect the in-display fingerprint sensor. Some glass protector makers are saying that their protectors work fine, but we’re not sure any of those will do better than basic screen protectors. It’s best to just use the S10 or S10+’ display without any protection and use a case that’s thick enough to protect the display from damage should it fall face down on the ground.

Don’t mind having to press hard? Just ignore what we’re saying

If you don’t mind the more finicky operation of the fingerprint sensor with a protector installed, you can let the stock one stay on the phone or upgrade to a tempered glass protector. Galaxy S10e owners can also leave the screen protector installed, as it doesn’t have an in-display fingerprint sensor.

Still undecided on whether you should buy one of Samsung’s new flagships? Check out our Galaxy S10e review and our Galaxy S10+ review for help on making that decision.

Wonder why Tech reviewers are having problems unlocking their S10 device & I got to say that the in-display finger scanner sensor right underneath the display isn’t large enough.

I haven’t used any screen protector ever since my tempered glass one broke loose from my S7 Edge when it fell to the ground. It did protect my device though, but it cracked severely. Also, I was having problems with touch sensitivity especially on the edges of the phone where I couldn’t tap on certain letters like A, Q, P, L, etc. Ever since my tempered glass protector broke and after many attempts of putting it correctly before (as well as trying out some plastic protectors), I realized that I was better off without a protector at all. After 2… Read more »

I actually removed the screen protector that comes out of the box, and accuracy vastly improved, another issue I have is that whenever i take it out of my bag(jeans) it actually thinks my leg was trying to yo unlock it and it won’t take my FP on first try and this make the whole process even slower.

Imo, until you can touch the screen anywhere to unlock, it’s just a gimmick.
Moving it from one place on the phone to another

It seem the under the glass FPS was a bad idea at this point, should have stuck to the rear sensor

It is not a bad idea. I am using it from the first day.And yes, you need a day or two to get used to it, but then it works perfectly. And I have the original screen protector on it.

Thought it’s a bug that they would fix in a software update, how can I remove the screen protector manually?
I keep getting “press harder” a lot and it gets on my nerves

Is there any other way of removing screen protector than manually? There is no app for this, just remove it from the screen

My issue with the FPS is having dry skin or slightly rough hands. Many years of martial arts doesn’t help. As long as I moisturise my hands the FPS works like a dream.

Still using the out of the box screen protector and have no intention to remove it. Seems to be lasting quite well

My Galaxy S10 still unlocks the phone with a smooth touch, but it takes longer to unlock the phone. If i press a little harder, it unlocks instantly. (Im using factory screen protector)
