Fingerprint app lock only

Hello all,
I'd like to use the fingerprint to lock only specific apps without having a lock screen active.
With other smartphones I can do it, with the P2 seems to be impossible.
In order to activate the fingerprint security, I have to record some fingerprints and that's ok. Then I select the single apps I want to lock.
But, if I disable a lock screen the digits scans are deleted, therefore the fingerprint app lock feature stops working.
In other phones when I disable the lock screen, the app lock function keeps working (fingerprints scans are not deleted).
Is there any workaround ?
I only manager to get partial workaround - I set option that the phone will lock itself after 30 min and I used simple PIN to use it quickly if needed and also I use smart lock so it will not lock that often...

The HUAWEI Nova Plus Fingerprint Reader Feature Is Just That Much More Amazing

I know you must have tried to lock the screen by fingerprint, but have you tried to lock Apps to enhance your information by fingerprint reader?
Not only this, you could also slide your finger on the fingerprint reader and you can enjoy some of the unique conveniences it provides.
Amazing, right? Today I'll show you the whole support of Nova Plus for fingerprint recognition.
Using fingerprints to unlock the screen
I'm sure that you have used fingerprint unlock a lot. It's simple to set up and then it's easy to use fingerprints to unlock the screen. You never have to worry about forgetting your password and you never have to worry that someone else will be able to see your personal information. Setting up the fingerprint reader is a must.

Unlocking with fingerprint, but asks for PIN every time.

I've discovered that if I lock my phone using the power button, the fingerprint sensor works fine and unlocks my phone. However, if I lock the phone using double tap, the fingerprint sensor will not work and it will ask for my PIN everytime.
Is this a bug or intended?
Nevermind I figured it out... I was using a 3rd party launcher.

Verify your identity prompt on all banking apps

Whenever I open my banking app I get a fingerprint prompt the screen goes dark and asks you to use your fingerprint to verify your identity it's really annoying and I've tried but can't find a way to remove it, it never happened on my note 8!
Turn off finger print then.
On some apps the fingerprint screen will pop up and darken the screen so it can show the information about the finger print scanning
do you use facial recognition? with my Note 9 due to Iris scan it basically let me in unlocking that way as it is secure, but with facial recognition on the Note 10 I was having trouble getting to use Google Pay and other secure apps, requiring extra security in the form of fingerprint or pin, I'm guessing due to the removal of Iris scan (my biggest disappointment) you need to either use fingerprint or the pin if you want to use secure stuff.
Are you running your app within the secure folder? Maybe that's verifying you before running the app?
Banking apps always require some autentication when accesing, as per security reasons, they log you out every time you leave the app

Not understanding.
If you want the fingerprint prompt off. Then turn off finger print in your bank app.
Also is it a finger print login or samsung pass login?

I do understand but I want my fps on but without the prompt like I said I never had this issue with my banking apps on my note 8
It's a finger print log in from the banking app
I think they are having the same issue I am with one of my apps. The app allows for fingerprint verification, however the setup requires you to type in your password, however in I can't do that as the fingerprint overlay is full screen abs I cannot enter my password.
What I would like is just a spot on the screen that says here put your finger here.... not a whole screen dedicated to the process.

S9 fingerprint problem (only on lock screen)

So last night I rebooted my phone and found that my fingerprint scanner isn't scanning my finger.
When my screen is locked, the fingerprint scanner doesn't work, it just doesn't respond (it's not consistent, when I use different lock methods (power button method, root method, accessebility method, Xposed method) it works one time and then again stops working)
There are 3 options of what happens:
I turn off the screen and put my finger on the scanner
1) the device unlocks
2) the device screen turns on and shows me the screen as if I pressed the home or power button
3) I get no response (this seems to be happening if I pressed the power button when the device is already locked)
1 and 2 are not always consistent, and I haven't pin pointed what the cause is
If 1) happens, then of course it works as expected and it will vibrate if it's the wrong finger, and unlock if it's correct
If 2) happens, it's the same as 1) just the device doesn't unlock, but just the screen turns on
If 3) happens, then it doesn't matter which finger, there is no response
I tried safe mode, it still didn't work.
I tried magisk core mode, also didn't help.
I saw someone wrote that it might be because of the dinner print gestures, but I don't use them, so I tried to activate them and they fully work even when the scanner isn't scanning my finger...
The scanner itself works, any app that I can use biometrics would recognize my finger...
And I know my fingers are still recognized, I made sure to check in settings... I even removed all my registered fingers and put in new ones, I rebooted between each step to see if it helps...
I have no idea what caused this problem, if any one knows please help.
My phone's situation is SM-G9600,
Magisk, EdXposed (obviously I tried the scanner after disabling both by putting magisk in core mode)
Android patch level from 1 September 2019
If this helps- build number: PPR1.180610.011.G9600ZHU5CSI2
I'll be happy to provide any information that might be helpful
The S9 has a common problem where the fingerprint scanner becomes unreliable even if there's a small scratch on it. Could you upload a photo of the back of your phone?
Here are some pictures taken with the phone through a mirror, no scratches on the sensor... Also it works in other situations, like anything that has somthing to do with fingerprint other then the screen lock.
I checked the the logs and I have some strange things there, for some reason the device is turning the fingerprint scanner off as if I don't have any registered prints... I also asked a friend to send me his logs, and the look like what one would expect, I'll attach the screenshots of both logs
