S21 Ultra (Exynos 2100) has a TERRIBLE fingerprint sensor/scanner same as Note 10+

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.

Exynos, as I said Exynos S20 and exynos a51

All exynos and snapdragon models have the same ultrasonic fingerprint sensor, so don't worry there is no differenc ethere

They made a mistake, it is an ultrasonic one, the optical one shines a bright green light.

I am having exactly the same problem.  It's much worse than the Note 20 Ultra which was just about ok if you scanned the same finger four times.  I am wondering if it is anything to do with the screen protector installed by Samsung.  Very disappointing as the phone is great otherwise and the battery life of the 2100 is excellent.

hi, I have removed my screen protector and it makes no difference. I have spoken to EE and I'm going to have the phone replaced in a few days. I am not confident it is going to be better but I will return the phone twice, if needs be, to see if either of the new ones are better. It the third phone is still as bad, I'll have a tough choice to make.

[fredphoesh]

good to know, then hopefully my replacement s21 ultra will be better.

I've done a factory reset and at the moment it's recognising my fingerprint 9 times out of 10.  If it follows the same pattern as the original setup and deteriorates until it's unusable EE have agreed to replace it.

[fredphoesh]

hi yes that is my experience too, that it works better for a few hours after a reset but then quickly reverts back to being rubbish. I had exactly the same thing with my note 10 and and despite many many complaints Samsung have done nothing about it. my wife's Xiaomi and my Dell xps15 laptop read my finger first time every time.
