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

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.
