In-display Fingerprint does not work 90% of the time. Even face recognition does not work in dark.

I have S24 ULTRA. In-display Fingerprint does not work 90% of the time. I used all types of tempered glasses, expensive to cheap, thin to thick. Regretting purchasing this phone just for unlock feature. Even without tempered glass it does not work all the time. 

Even face recognition does not work in dark. By dark does not mean complete night. Even if its 50% dark and Samsung struggle to unlock via face.

In-display fingerprints should be banned. 

This is not smart feature if someone can't use properly.

Make sure screen is clean and turn on screen screen sensitivity especially. If you are using a screen protector

Already done.

Hi @singhaman 

To be honest I'd like one on the powerbutton as like the Samsung Fold³ I owned. That worked flawlessly. 

That said the fingerprint scanner works fine for me most of the time. I made two fingerprints of my thumb I always unlock with making sure I registered all the edges of my thumb too. 

I use a Spigen Ez Fit Glass Screen Protector. 

I believe my own mis hits to unlock are because I do have dry skin. Breathing on my thumb before pressing down works. 

Face recognition works as long as it's not too dark where I am. 

If i can be of any further help please don't hesitate to ask  😎

I have the same problem, all that tech in your hand yet it can't even do some basics Like face & finger print. It was OK on my s21 ultra most of the time.

I've the S24 and with similar experience that you have. Screen protector or not - it's the worst in-glass finger-print reader I've ever owned and that's bad since the face id isn't that great either. Tried setting screen sensitivity on, but I could only notice a slight improvement. I found it strange that there are not more posts about issues related to the built in sensor.

It's been my personal experience that the problem may not be the phone but the placement of our finger.  Bear with me. 

Once I went to Settings / Device care / Diagnostics / Phone diagnostics  ... and played around with Fingerprint recognition sensor, I quickly realized I had not been using the fat part of my thumb over the sensor in the most effective manner.   

I also have the same finger, well, my thumb, registered four times and registering the same multiple times may also work to your advantage.  

Take some time trying that sensor in that Diagnostics test.

Mine seems to work OK again, not 100% but about 80%, then again I am older mine are very worn due to hard work (I say) lol, at work we have finger print scanners to clock in/out so I know they are worn because Rarely anyone else has to do it on those as many times as I do& there's about 400 on a shift.

I'm can't believe it how is this possible on expensive phone like 800/900$ possible to not work face id unlock and finger print . Like every iPhone phone on 11 to 16 work wonderfully unlock in dark place and nothing make problems for unlocking phone . Then buy iPhone for 200$ and you have full unlock instantly . I think I will go back on ios . This is to much money . Bad cameras after one year lose quality 😪  Too much bugs in sistem. Front camera say me it's dirty but it's perfectly clean !!! 😏  Samsung please make it better i know you can ! Then do it ! More update repair if is possible ! Regards

That option not work properly ... 😔
