Are you disappointed with the Galaxy S20's fingerprint sensor?

Samsung's Galaxy S20 has quite a lot going for it. The 120Hz AMOLED display is downright gorgeous, battery life is stellar, and the upgraded camera system is a joy to use.

The Galaxy S10 introduced in-screen fingerprint sensors for the first time on Samsung phones, and the same ultrasonic sensor made its way over to the S20 as well.

Looking through the AC forums, there are mixed feelings about how well the sensor performs on the S20.

So far, I like everything about the S20+ except the in-screen fingerprint sensor. The fingerprint sensor is too small and it only works about 75% of the time. The in-screen fingerprint sensor on my OnePlus 7 Pro was far superior. BTW, the S20+ still has the factory installed screen protector, as did my OnePlus 7 Pro.


Sorry you've had that experience. Mine seems to always work and I'm coming from a Pixel where it was on the back. I don't keep screen covers on though.


Im coming from an S10 and I find the sensor on the S20 plus much better. I think they are the same sensor but the placement on the s20 plus is a little higher up, so I think this is whats giving me better readings. When I pick it up the phone my finger is right on the senor so I only have had a few times where I had to try again for it to read. My s10 was 50/50 so I stopped using it all...


No issues here, scanned thumb and index finger on each hand one time. Factory installed screen protector is still on the phone, and I have not had one misfire yet.


What about you? Are you disappointed with the Galaxy S20's fingerprint sensor?

  • I have no issues with the fingerprint sensor. Try setting up a new scan. I have 3 scans set up as of now and will probably do more.
  • You mean with the same finger?
  • Yes... No... Maybe...
  • I thought I would be disappointed, but it's actually pretty good. I entered each print once. Add the convenience of Smart Lock on top and it's all good.
  • I'm more disappointed with the prices.
  • I haven't had an issue with the reader unless I didn't put my finger on the sensor. I miss the S8's swipe gesture to bring down the notifications, but that's all. The under screen reader is much better for when my phone is in my car dash mount, and I like not having to lift my phone to unlock it with my finger. I have multiple scans registered and no issues that weren't my fault. I like that the reader was moved high than it was in the S10.
  • Love my S20+, hate the fingerprint scanner. I have 4 fingers set up and I'd say it works maybe 50% of the time. I'm going to redo them, maybe at an angle since that's how I'm typically unlocking my phone. Hopefully that helps. I don't have a screen protector on mine.
