S8+ Lock Screen Not Working - Samsung Galaxy S8+ Questions & Answers

Dear XDA Bros and Sisters
I'm new here and just signed up. I Just got my Samsung S8+ and it work fine for a few hours including the iris scanner security lock..but suddenly i can swipe open my phone without the iris scanner or the pattern password being asked. I restarted my s8+ a couple of times..i tried to change the security method but no luck.
Anyone can open my phone since the security that Samsumg prides itself off seems to be defective on my S8+...or Can it be my fault? I dont remember changing the other settings though. Please advice. Thank you in advance.
Respectfully yours,

Hi, have a look under settings - lockscreen and security - smart lock. You may have inadvertently enabled unlock in a trusted place or near a trusted device.

Usually the smartwatch or the bluetooth headphones, which is frustrating because you always have them and can't seem to find the problem, ahaha.

Xperia Z5 bypass screen lock when fingerprint doesn't match.

So, I've just got my Xperia Z5 yesterday and today I was configuring the fingerprint reader.
After I've finished it I've tried to unlock the phone using the fingerprint and everything works great!
The thing is, when I use any non registered finger it fails to unlock, as it's supposed to do, but, after it fails if I just slide up the lockscreen, the phone unlocks normally.
Is this the expected behavior? I mean, I thought it was supposed to ask for the security pin if the fingerprint didn't get recognized.
Thanks for your help.
I think you have either a Trusted Location or a Trusted Device added/connected in the Smart Unlock
When fingerprint fails, it's supposed to lock fingerprint scanning and ask for password or PIN depending on your setup

OMG, I feel completely dumb... It was my Smartwatch 3 added as trusted device, I can't believe I haven't think of that.
Thank you very much for your help solving this non-problem, I was getting crazy over it. xD

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.
Best.
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.

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
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.

Disable lock screen

Hello all. I have a problem. I can not, for the life of me, figure out how to set my lock screen to 'None'. I've tried:
Disabling fingerprints and fingerprint unlock,
Disabling smart unlock and any trusted agents
Disabling and uninstalling Android Pay and Android Wallet,
Disabling NFC,
I have no VPNs
I have no administrators enabled,
I have cleared my credential storage,
powered off my phone and powered it back on
I do not have any encryption enabled
and still 'None' is grayed out with the "Disabled by Administrator, encryption policy, or credential storage" message.
I just can't think of anything else to try in order to disable the lockscreen. Can anyone please help me?:crying: Thank you for anyone help anyone can offer. I'm desparate!
You seem to have tried everything. Only thing else I can think of is I know sometimes if apps are allowed draw over others, the phone can block some security settings.
Just a suggestion, but if you go into your apps in settings and change it there, maybe it'll work
All I can suggest then is a factory reset unfortunately, I cannot think of anything else to change
Sorry I couldn't be of more help
Draw over other apps
Should I disable Draw over other apps for every app in the list or any one in particular?

I have exactly the same problem,after factory reset it s ok,but after instalation couples of apps and other stufs again is the same...i dont know where is problem...is anybody resolve this without factory reseting phone?
We have this issue on our Honor 8. It's my son's phone so I can't test possible solutions. One I read was to remove all credentials. Since I don't have the phone, I have no idea where credentials are. Another I read said to create a pattern lock and a pin emergency lock. Use the WRONG pattern 5 times or until it requires the back-up pin. Enter back-up pin then the "none" choice returned. It will be a few more weeks before I have access to the phone. If either works, please report back.

Samsung S8+, Secure Start-up disabiling automatically! any idea why would this happen

Hi,
This has happened randomly that Secure Startup Pin has disabled automatically without any notifications. Phone has no physical damage, other lock security settings work perfectly, has never been dropped or jail broken.
Hey man i have the same issue. Did you get this sorted out?
For me, this happens when I am using assistive Apps like LastPass. It is, however, asking for the pin code and giving a hint.

My pattern lock is fubar

Hi XDA, I have a Galaxy s8+.
My pattern lock is acting goofy, won't recognise the correct pattern. Fingerprint works fine so I can get into my phone. But entering security settings to disable pattern requires pattern.
Kind of scared to turn off my device.
I have all lost device software enabled and signed into Google. What can I do?
Edit: OK while I have both Samsung and Google Find My Device enabled, in my android settings apparently I didn't give permission to remote unlock. Turn it on? Requires pattern.
Thank you kindly ilu
