Lockscreen Bug

Can anyone confirm whether this happens to them. I have fingerprint lock with either a pin or pattern as backup.
If on the lockscreen I swipe the screen rather than use the fingerprint lock the pin/pattern screen comes up with the blurb "Use Fingerprint or draw unlock pattern" However when i then put my finger on the scanner it doesn't register, its as if i haven't put my finger on the button. The only way I can access is via inputting pattern/pin. Once i have done this i can repeat by locking the screen and swiping and the reader registers.
However if i leave the phone for 10-15 minutes it then goes back to not registering the fingerprint on the pin/pattern screen again?
Anyone else getting this?
Getting the exact same issue on the Galaxy S7Edge with Australian firmware, and it completely ruins the usefulness of the fingerprint unlock method.
It's definitely a bug in the software - a few people have already experienced the exact same issue we have encountered over at:

Hopefully Samsung are at least aware of the issue and can patch it..
I had something called lock screen launcher or something like that I did uninstall it and it was normal again

Fingerprint Scanner Problem

I have a problem with the fingerprint scanner, when i register my fingerprints it takes alot of time to complete the register process. I get a lot of partial fingerprint detected errors or it is isn't recognized at all. I can complete the sequence, but it take a lot of tries. Whenever I try to unlock the phone, most of the time it wil unlock, but sometimes it won't detect my fingerprint. Sometimes I will get the error, that my fingerprint isn't recognized even when I am not touching the fingerprint scanner. Does anyone else has this same problem?

It really looks like a hardware problem with your fingerprint scanner... You should use your warranty to fix it or change it for a new one.

Biometrics not working

I was in the car and my phone slipped out of my pocket and landed on the carpet.
Fingerprint reader stopped working.
Face unlock was still working.
Factory reset the device
Fingerprint reader still not working.
Face unlock still working.
Can anyone offer a suggestion or know what I can do.
bump
Send it back without mentionning the fall? Just say that the fingerprint readed stopped working.

Fingerprint scanner not working! Request for schematic diagram / board picture for u11+

I already tested with a new fingerprint scanner and it still doesnt work. If i attach the fingerprint scanner and turn my phone on, it would start in a bootloop saying "Phone is starting". I had to remove the battery to turn off the phone, unattach the fingerprint scanner, turn on and it works just fine. Well, fine without a fingerprint scanner. So i was wondering if there is something wrong with my board. If any of you have a picture of the board, near the fingerprint scanner area, it would help too.

I already tested with a new fingerprint scanner and it still doesnt work. If i attach the fingerprint scanner and turn my phone on, it would start in a bootloop saying "Phone is starting". I had to remove the battery to turn off the phone, un-attach the fingerprint scanner, turn on the phone and it will startup like normal. Well, normal but without a fingerprint scanner. So i was wondering if there is something wrong with my board. If any of you have a picture of the board, near the fingerprint scanner area, it would help too. Thank in advance!!
