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.

Same here. The worst fingerprint and face id sensors I believe. So disappointing for me as a samsung phone user for a long time now.

Same issue, brand new S24 ultra (Aug-25 manufactured). Bought premium Spigen tempered privacy glass cover (, the fingerprint (that was lighting fast before using the glass cover) just refuses to work now, only works when I press hard for half a second, I tried everything:
1. removed fingerprints and reapplied

2. Did the diagnostic check, fingerprint shows error, pressed hard only then it works

3. Added 3 fingerprints of just my right thumb (two of left), still misses 6-7 out of 10 times.

4. Added fingerprints with a moist finger, as per a reddit suggest, not working.

5. Disabled touch sensitivity as advised by others online (should be opposite)

My 4 year old S20 FE 5G, the fingerprint is so amazing that it registers the fingerprint faster than the unlock. I press my thumb for a nano sec and take it off, the phone registers it and opens the phone half a second later, which clearly means the fingerprint is superior. 
Extremely disappointed with this, using a pattern for now which sucks!
