Wonder why they would block a diagnostic tool.
In the Samsung members app they offer a fingerprint test also
Samsung members>get help>interactive checks>fingerprint
Make sure you have the latest version from the galaxy store:
Thanks for the tip! Thats a great resource. I'm not sure why the diagnostic menus are disabled by Verizon. It seems really silly to me.
Anyhow, I took your advice and went through the steps, but it requires me to register a fingerprint to continue with the test... which of course I cannot do. This is beginning to become humorous if nothing else.
This site has some good recommendations to also try before replacing it. If these last two options dont help then I would recommend getting your device serviced by a professional so they can determine the issue
Check for Possible Bad Third-party Apps
Another solution to fix Samsung Galaxy S9 fingerprint not working you can use is to boot your phone into safe mode. If fingerprint scanner works on safe mode but not normal mode, that means one of your third-party apps is to blame.
How to put your Samsung Galaxy S9 (Plus) into Safe Mode:
To identify which of your apps is causing the issue, you should boot your S9+ phone back to safe mode and follow these steps:
Wipe the Cache Partition
When fingerprint scanner is not working on Galaxy S9/S10, and you need to fix it, try to wipe the cache partition in your smartphone.
I've booted into safe mode, and it still isn't working. I've also wiped the cache partition as well. It seems as though all signs are pointing to professional servicing. You all have been very helpful. I really appreciate it.
I have the same problem.
I own Samsung s8 plus. Never had problems with Fingerprint sensor before. Just a few days ago it decided to stop working.
When I try to unlock it It says THE FINGERPRINT SCANNER NOT RESPONDING. TRY AGAIN LATER.
When I go to setting to fingerprint sensor SAME MESSAGE.
Also the swipe motion across sensor to pull down the notification tab doesn't work.
Tried every advicesin settings and it doesnt help.
Tried Booting in safe mode, doesn't help.
Tried clearing the chache, doesnt help.
When dialing *#0*# and selecting fingerprint normal test in the sensor menu. The app crash.
The thing is Samsung wants to update my phone but I don't want it.
I will try to replace the fingerprint sensor.
I hope its that because I dont want to slow my phone down with updates.
They really want me to buy the new phone.
