Cannot use fingerprint to unlock after using screen off app - Samsung Galaxy S8+ Questions & Answers

Hi there,
I tried to use screen off apps on my SS S8, but when unlocking, it requested PIN numbers instead of using the fingerprint.
The fingerprint only works if we lock screen using the physical button or after timeout.
Do you happen to know any workaround for this?
I read a thread on S7, suggesting using Nova launcher with Screen Lock widget. But, is there any setting we can change to use other apps?
Many thanks,
Nghia

That's general security setting of Android. Happens to me on my OnePlus 3 when it's locked by Greenify. Simply ditch those lock screen apps.

hello,
it is a know issue, try Double Tap to Turn Off, will solve this problem, I am using it and I can use iris, fingerprint, face and of course PIN.

I use nova launcher plus lock screen to double tap gesture. Works fine.

How do u set it up in Nova?
Figured it out, nevermind. At first I thought it was built into Nova, but found the app and set it up. Thx

I was wondering if there are other apps can fix this as well.
Many thanks!

Played around with that app a little more, you actually need to enable that "show clear view" option, what it does is it would show the time on the screen for about one second before showing the AOD screen.

Use "softkey edge" which is a edge app works perfect. U can use iris or fingerprint after lock the phone using this edge app. Also it do not use device admin access..
You can download from galaxy apps and not avail in play store

OFF+ app work!
I have same issue with Samsung S8. Finally I found app called "OFF+". Just need to change screen off type to delay mode in app. Work perfectly. No issue with fingerprint! :good:

Do you have a link to this app?

This one works for me:
https://play.google.com/store/apps/details?id=gr.ictpro.jsalatas.screenoff

I tried those other ones and did not have luck.. either the app did allow fingerprint but did not turn the screen off in a reliable way.. or they required pin / password to unlock..
but just found this one and it works so far!
https://play.google.com/store/apps/details?id=com.redmanit.lockscreen

If this is still a question for anyone:
With nova launcher, you need to give it accessebility permission and choose in the nova settings to use a different lock screen method
The setting can be found in the nova settings by scrolling all the way down and choosing the last option in the advanced settings... Each option has an explanation for how it lockes the screen

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.

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

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?
Sent from my SM-G935T using Tapatalk
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 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

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.

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.

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.

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.

This is a duplicate of: http://forum.xda-developers.com/galaxy-s7/help/security-policy-prevents-fingerprint-t3354270
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

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..

All the applications i have found seem to do this. You have to make the application a device administrator for it to work but because the application is controlling the lock, the fingerprint doesnt work and it forces you to enter the pattern. I am coming from a moto and really miss the breathing notifications.

I use this at night but I don't really want the screen on all day, if this had a "breathing" function it would be nice. Hoping google releases an update to change the ambient display.

Using Notific Pro without administrator permissions, only enabled notification access on the overview screen of the app. Works pretty well for me...

Quick Launching Camera from Lockscreen

I must be missing something but hell if I can figure out how to launch the camera from the lockscreen.
Used to be able to do it with a double power button click on my S8 but on my VZW Pixel 3 it brings up the code unlock first. I find that there are many times I just want to take a quick shot without having to unlock the phone.
For that matter, does Pie offer lockscreen widgets at all?
Thanks for your help.

Ah, yes, those were the days (pre-Lollipop) when my lockscreen was super useful and interactive, and so was my notification ticker in the status bar. I feel like an old man now remember how good things USED to be. lol
But to the OP, something is clearly wrong as this feature is turned on by default on Pixel devices. Try a factory reset. You can backup your phone to your computer using the adb backup and restore commands.
Did you select Camera as default app when launching with the phone unlocked? The first time it will give you the "open with" dialog. For me it was Camera and Snapchat. I selected camera and always, and now can launch camera from anywhere.

Works for me with pattern lock, don't use pin.
Just go to the camera settings then scroll down and turn on Quick launch
Enter your pin, and select one of your camera apps as "always" then it'll allow you to skip the pin when you double tap. ?

Thank you for the tip!
I hope by now the problem has been resolved, I was also looking out how to access the camera from the lock screen and it turns out (thanks to advice from friends not from anything I found from the many internet searches) that if you click the power button twice the camera pops up. You can check this by going to Settings- System - Gestures - Jump to Camera.
