Fingerprint Sensor

[S10userUK]

Hi,

Since last month I have been having issues with the fingerprint sensor on my Galaxy S10 phone. It will no longer read any scans, constantly gives an error of "make sure your finger covers the entire sensor" and then on the odd occasion it does sort of read I get the "press harder" error. Very, very rarely, I get "No Match", so I know the reader does work, sort of. 

I have tried to remove prints and readd them, but these errors also come up in the add fingerprint section, so I cannot add new fingerprints. 

I have tried different fingers, made sure hands are clean, dry, etc. 

I do not use a screen protector, so that is not part of the issue. I have also tried the more sensitive screen option in the settings. 

I have tried clearing the cache as recommended by Samsung. Nothing seems to work. 

I'm wondering if this can be caused by a software update, like the monthly security patches, etc. Or do I have a sensor that is now beginning to fail?

Any help would be appreciated. 

Thanks

I sometimes register the same fingerprint multiple times. But use a different angles when registering each one. Seems to work fine for me.
As long as the screen is not damaged and is clean, it should work.
I'm sure you know, but just make sure when you register, your fingerprints are clean, I wash my hands a short while before. So the skin is not too dry, as my skin can get a bit dehydrated and the scanners don't pick up that well when registering.

I have tried that. I did have the maximum 4 prints registered, 3 were all the same finger. I have then removed 2 (1 of the 3 same finger scans, and 1 of my thumb that wouldn't match) So I now have 2 registered, of the same finger, but I cannot add new ones as I just get the errors mentioned above.

The screen itself is perfectly fine. No scratches, no cracks, and fully touch sensitive across the entire screen. It is a very odd problem.

Hi, I have tried that. The scanner does a 10 second count down, and I keep trying to scan. I get the same errors I mentioned originally, nothing scans, the 10 seconds counts down and the diagnostic then closes.
