hey guys i activated the app lock but there is a problem the app lock requests for fingerprint only once after it is unlocked then you can open and close the app without security why is it like this??

Avoid power button problems with LockScreen

As we can unlock our Nexus 5X with our fingerprint in a comfortable way, I think LockScreen is also great to lock the device from a (material design adapted) widget. And you can also use transparent widgets!
You can download it from Google Play (it's free!).
I've developed this app so, please, any feedback is welcome!
Best regards!

Doesn't work correctly on the 5X, once you have locked using the widget, you are then unable to unlock again with the fingerprint reader, you have to then use the keypad, that defeats the object of having a fingerprint sensor.

Awwww. What a shame. Would have been a good a good interim feature until we got a DT2W and the like

Personally I lock my screen by setting double tap in nova launcher to do the hibernate and lock screen feature from greenify. Fingerprint still unlocks the phone without using the keypad

I'm pretty sure it does not... same issue with this.
Unless you create a widget that activate a root task to lock the screen, it will ask for the keypad.

I use nova launcher's gesture control to also launch Greenify's Hibernate and Lock Screen. Which works as intended... Fingerprint scanner unlocks device. Maybe im missing something in what you are saying.

Just tested it already too, does not work for me.
And it seems to be a known issue since 2 others thread are talking about it already
Maybe there's something you guys have done differently that make this work but I've done this :
1/ setting double tap on home screen with nova launcher to launch Greenify's Hibernate and Lock screen
2/ once device locked and screen turned off, puting my finger on the fingerprint. It does wake the phone but asks for the pin code which does not when you lock the phone with the hardware power button
And it's the same behavior with other launchers and apps that can turn off the screen

The only thing i have done is root the phone no other system modifications have been made on my device i am still encrypted, no custom lock screen or any of that business.

All I've done is root my phone and given greenify root access.

I've removed encryption, maybe that's the thing that's triggering this behavior

Can't unlock by fingerprint once locked by your app.

Same here - been looking for this feature and still havent found it - not interesting in root either and losing all the functions that go away with that.

Any solutions yet? Not rooted.

Any app that locks the screen, fingerprints doesn't work afterwards. It's not just this app.
Same thing happens when using Screen Off app https://play.google.com/store/apps/details?id=nl.matthijsvh.screenoff

mine is rooted and i use greenify "lockscreen+hibernate" widget without a problem

Nova Launcher / DT2S / Fingerprint Scanner Won't Work

When I use the Nova double tap gesture to lock the screen (using Greenify, Screen Off and Lock or Screen Off), I have to type in my pin to open the phone (it won't let me only use the fingerprint scanner). When I shut off the screen via the power button the fingerprint scanner is all that's needed . Do you guys know of a work around to use DT2S while being able to still use the fingerprint scanner to reawaken the phone?

Mine is working with Nova, you don't need Screen Off anymore, it's built into Nova for awhile now.

I noticed that but I still have to enter the pin after diuble tspping even though fingerprint is enabled. Weird.
Sent from my SM-G935T using Tapatalk

same here, kinda sucks that I have to keep entering the pin

I'm using swipe up gesture to screen off. Fingerprint unlock is working

Same here. It works but I have to put in my pin after fingerprint.

same maybe it's something that we disabled that broke something?

So I had the same thing. Its actually greenify. Took me a while to figure it out because i was in the same boat. Uninstall that and try the built in app control. I'll still throw down between 5-6 hours screen time without greenify

I use the same exact setup and my fingerprint scanner works perfect.
Sent from my Samsung Galaxy S7 using Tapatalk

It says when you use this why it does it, you'll need root to get around this issue and enable root mode in Nova Settings.

that doesn't make any sense. mine works completely fine by doing this. I never turn it off using the power button and I always unlock it with the scanner.
Sent from my Samsung Galaxy S7 using Tapatalk

I tried it again with Greenify and the other double tap to lock apps uninstalled and set Nova to use its own lock device setting yet I still have to enter my pin when turning on the screen using the fingerprint scanner. It's bizarre.
Sent from my SM-G935T using Tapatalk

I have the same problem. Galaxy S7 + Greenify or Screen OFF, every time I have to enter the PIN too. It is very annoying. I hate to use the side button to shut off the screen, I need one of these apps to work properly with the fingerprint scanner.

same here, have to use the pattern after Nova's double tap lock.

I think the issue shows up if you are also using Smart Lock. I installed Screen Lock Pro and use it in the Nova gestures for double tap and it works great.

Screen Lock Pro does not require your password after fingerprint? I tried two different lock screen utilities and both still required my password.

Correct. There is an option you need to select that I should have mentioned. Smart lock and Nexus imprint must be selected and then it will work. You do need the pro version.
Back on my G3 with Nova I had this same issue when I enabled Smart Lock. I also tried many apps and could not find one that worked. Glad someone on Reddit posted this solution

Fingerprint unlock problem

With latest firmware (G930FXXU1APD1-G930FDBT1APC5-DBT) Im having problems when unlocking the device with fingerprint. It does not allow me, but instead I get:
“Enter pin instead of using fingerprint recognition because of security policy”
And I have to use the PIN.
This happens when locking the display with “lock wedged”. If the lock is made with button (power) ... or time out display. Then I can normally use the fingerprint.
Does someone also facing the problem?
Is there any solution – setting?
Best.

Yes i had this and tried to reset my fingerprints when i tried that settings error and closed, then i couldnt change anything, pin, fingerprints, couldnt even factory reset. Cause it always asked for my pin and after i entered it settings would error rebooting didnt help. Finally using android device manager from my pc i had to do an erase. My s7 is stock and it had nothing disable at the time this happen.

there might be extra Policy set on ur device.
go to setting > Security > click on Clear Credentials
+ also check what is ur device administrator
:good:

I had that even on my Nexus 6P when using Nova's double tap to lock feature. I think it's something to do with Marshmallow actually.

Clear credentials is not active.
Device Admin - APP is added.
So the error is still there.

You can try Samsung's Good Lock app from Galaxy Apps store or, if you live outside U.S., from apkmirror.com. It's a System UI update that allows fingerprint unlock with third party locking widgets.

@ avah
This actually works. But ... then I get totally different lock screen display etc... that I actually don’t like.
So ... till now ... no real solution.

Hay
Question.
Is it possible to flash the phone back to previous ROM version via Odin… and you won’t get Knox void .. or something else??
I'm thinking to go back to previous ROM when lock and fingerprint worked OK.

You can find details on that thread about this problem.

I'm having the same issue and I must say it is very annoying. Can't really see any reason why this should interfere with the security. Should be my choice to be honest. Would be nice to have a solution to this. Looks like it's been an issue for a long time as well. Found some threads about the 6P for example with the same issue.

Try use other app to pass that policy: https://play.google.com/store/apps/details?id=com.luutinhit.doubletapscreenoff

When using app: https://play.google.com/store/apps/details?id=com.luutinhit.doubletapscreenoff please choose check box show clear view to fix this problem.

Yes but the problem still remains so it was a good initiative. I've got a brand new S7 and I find this very annoying. If I switch off my screen with Nova, I have to use fingerprint+PIN Code to unlock. If I switch it with physical buttons, I only have to use fingerprints..

Fixed
Search 4 knock on app on playstore.
Instal
Tap on create icon. Turn off the rest options

Fixed by installing a third party screen locker.

New Verizon update booked my fingerprint unlock

Title says it all, Verizon update at the beginning of September left me unable to use fingerprint unlock. I know it is a software problem because I can still use my fingerprint for web sign in and purchases. When you try to unlock it says "use pin instead of fingerprint due to security policy" anyone got any ideas?

do you use another app to lock your device such as a double tap gesture in nova? if so that is why I had same issue and disabled the gesture and all works fine now. You can test it lock with the button and it asks for fingerprint there you go.
