I am shocked and really sad about this. The fingerprint scanner on my brand new S21 Ultra IS TERRIBLE!!! See the YouTube video I made to show it took me about 100 tries to add my left thumb, then it failed. VERY BAD Samsung!!! https://youtu.be/4Mp8ECNUpgQ  

I have managed to scan 3 of my right hand fingers, and it almost never unlocks on first try, regardless of finger used, comparing with my Note10+, the poor performance is identical, so is the feel and way the scanner works, so I am sure they are the same scanner and am sure that the Exynos does DEFINITELY NOT have an ultra-sonic fingerprint scanner.

Maybe the Qualcomm version is great, but this is extremely disappointing and is the reason I returned my Galaxy S20, Galaxy Note 20 Ultra upgrades after a few days, and now it looks like I will be returning this phone. It is not a substantive upgrade on my Note10+ the same annoyances.

I believe they are wrong, the difference between my note 10 and s21 fingerprint scanner is like night and day. also the surface area has improved considerably.

even a little tap of the fingerprint scanner will unlock my phone straight away with the s21, which wasn't the case before with the note 10

Sadly they confirm the fact that the Exynos s21u has an optical sensor and not an ultrasonic one.

how does a fingerprint sensor get bust? I'll send this back and ask for another, but given it has the same rubbish optical sensor as the S20, I don't expect any change.

I believe ya, I definitely think your phone is broken however.

I've just turned on my note 10 and tried the fingerprint and it is definitely an improvement. not sure why samsung support are saying it comes with the last gen sensor when it doesn't on the exynos. at least it shouldn't do.

there's a few teardown videos on YouTube that show the exynos does infact have the new gen fingerprint sensor.

I'd go get your phone replaced if I were you as long as you are not using a glass screen protector that could interrupt it for example

so it seems now they are saying that it does indeed have the ultrasonic fingerprint scanner. I will return this phone for another s21 ultra and see if there's any difference...
