Galaxy S21 Ultra ReviewSource: Hayato Huseman / Android Central

Samsung packed a ton of improvements into the new Galaxy S21 series, and out of everything on offer, there's one feature upgrade that's easy to overlook — the fingerprint sensor.

The Galaxy S10 and S20 both featured ultrasonic in-screen fingerprint sensors, and thanks to slow performance and inconsistent readings, they left a lot to be desired. Samsung finally fixed this with the Galaxy S21, offering a new sensor that's larger and more accurate.

We've been really happy with its performance on the S21 so far, and taking a look through the AC forums, this is what a few of our members have to say about it:

I've definitely noticed it's not as good as when I first got it. I think I will have to try setting my fingerprints up again.

Mines has been pretty good even with my screen protector on. I would try resetting your prints.

It 100% is the new update that breaks it! Mine isn't working 80% of the time now. Also confirm that re-registering your prints works, although is bs that you have to do this

No matter how stable Android gets, it's still too hard to master

Android and the services that it uses have come so far since I first came to the platform in 2012, but it's still far too complex to troubleshoot and truly get everything exactly the way you want it. I've been writing Android help guides since 2014 and even I have to marvel at how hard some of these settings are to find.
