PSA: Galaxy S10 in-display fingerprint reader gets better with time

New technology always takes some time to become as good as something that has existed for a while. That’s certainly the case for the in-display fingerprint sensor found on the Galaxy S10 and Galaxy S10+. As we noted in our review, the ultrasonic fingerprint reader on the Galaxy S10+ is not as consistently accurate and fast as the capacitive sensors we have seen on Galaxy phones for years.

Not everyone will take a liking to the in-display sensor right off the bat and will take longer than others to get used to it, and we just wanted to tell you that if you are still cribbing about the fingerprint reader on your S10 or S10+, it really does get better with time.

It’s all about muscle memory…

With no physical boundaries to guide you, the biggest obstacle for in-display fingerprint sensors was always going to be the part where you have to get used to placing your finger in the right position. And that’s the case with the Galaxy S10 and S10+ as well. It’s easy to tap the right part of the display if you’re looking at it, but it can take a couple of weeks for muscle memory to be created for the action if you tend to try to unlock your S10 or S10+ without looking. And believe us when we say you eventually do start putting your finger on the right spot even without glancing at the phone first.

… and a little about AI as well?

Here at SamMobile, we have also noticed that the Galaxy S10 and S10+ get faster at fingerprint recognition with time. This is probably some AI trickery that allows the phone to take less time to recognize your fingerprint after repeated usage, and whatever it is, it certainly helps. Accuracy has also improved, with fewer instances of the phone telling us to keep our finger on the screen a bit longer or telling us it found no match, although the latter was never really too big of a problem in the first place.

Galaxy S10 fingerprint recognition will improve further with updates

And things will improve with updates, as Samsung has confirmed, so if you are finding yourself cursing the fingerprint reader on your Galaxy S10 or S10+ even after a week or two of using the phone, just hang in there. The same goes for those who are still holding off on purchasing an S10 or S10+ because of the reports about fingerprint recognition not being that great.

Of course, if you aren’t willing to put in the effort just so Samsung can advertise the in-display fingerprint technology on its latest flagships, you can opt for the Galaxy S10e, which is an excellent compact flagship with an extremely fast side-mounted fingerprint sensor.

What mean PSA ?


Well, i am not sure about that AI stuff mentioned here. If you look at the notice posted in the Samsung Members app. It states after every update de-register and register the fingerprint again to have the best experience. I think the problem is due to the preinstalled screen protector and Samsung is working out an update so it can work when it should work. face unlock is pretty fast though….


For me it works fine most of the times but in the morning when I unlock the first couple of times it consistently fails.


Very good points Abhijeet. Just like One UI, I don’t use the nav buttons or even the guide bars anymore for navigation. After a short while, you know where to swipe.


I am very pleased by the ultrasonic fingerprint sensor in my s10+. When I am holding the phone in my hand it never fails. But when I put it on the desk and try to unlock, it fails from time to time…but still it’s ok. It’s also as fast as my old s8+. So if it gets better with time…that will be just great. Best phone Samsung ever made. The whole thing is just incredible…battery, display, smoothness ,camera. Perfect phone. I will hold it for sure until s12 or even more.
