the screen lock pattern won't work

Oh yeah.. Guys. I found a weird thing with my phone and I need help. I am running ADW launcher EX and even after uninstalling etc, the screen lock pattern won't work. It only appears once when I reboot my phone and when I turn off the screen and turn it back on, it just brings me to the page I left without the screen lock pattern. Anyone knows what's wrong??

Thanks for the understanding.. I know all you guys were great from the start! Btw, I need help with my phone. My Unlock pattern won't show up and it's bothering me. It will only appear when I boot up the phone and for the rest of the time, it won't appear when I turn on my screen and it brings me straight to my home page. Do you guys know what's the problem?

What is your security lock time out set to?

Damn, thanks. I looked at it and found out it was set to 30 minutes.

Lockscreen

My first issue with the phone. I was playing around with the lockscreen as I was bored. Normally I don't keep my phone locked. After setting a lock pattern and setting all the smart lock features I decided to disable the lock. Originally I had it set to swipe. When I went in to the Screen Lock setting screen to put the phone back on Swipe I could not. It was disabled. In fact the only options I could choose were Pattern, Pin and Password. I disabled all the smart lock features but that didn't help. I restarted the phone and that didn't help either.
So now I can't disable the lock screen. Anyone know what up?

I read that clearing credentials fixes the issue so I tried it. Nope, didn't fix the issue.

OK, for ****s and giggles I cleared the credentials again and now I have all the unlock options. I don't understand why that was happening but who cares.

THANK YOU THANK YOU THANK YOU!!! Just like you, I normally do not use a lock screen. But I was visiting family and left my phone out to charge, so I added the pattern password and then it would not allow me to turn it off - all I had was Pattern, Pin and Password. After clearing the credentials, I gained access to be able to disable the pattern lock. Thanks again!!!

Lock screen pattern changed on its own, possible bug

I unlocked my phone normally several times today using my pattern. Five minutes after I had unlocked it, I picked it back up and drew my pattern and it said it was incorrect. I tried several more times with no change. I was able to unlock the phone using my fingerprint, but I have no idea how my pattern changed without my permission. If my phone dies or restarts for any reason, I will need the pattern to unlock it, as you can't use fingerprint on start up. (I've had the same unlock pattern since my last phone, so I'm sure I am putting it in correctly.)
Has anyone else encountered this bug? Is there any way to create a new pattern using my fingerprint? Finally, how should I go about reporting this to Samsung?
Thanks.

Yes!
Same thing happened to me... S7 working great for first few days when suddenly it didn't accept my unlock pattern. I've been using the same pattern for awhile and unlocked the phone a few times that morning. After a few reboots it finally accepted my pattern again. Immediately disabled it and now using pin instead.

Did you just restart again and again until it worked? If it worked for you I might try it instead of the factory reset.

I've had lock screen issues with my LG V10, but not quite like yours. I use a pattern, not a password or fingerprint. Sometimes the screen is locked and I fail the pattern and the phone gets unlocked anyway. Usually, this is associated with having first touched a notification with the screen locked. What happens after the pattern fails (trace shows in red), is that the screen appears as it does when it's not locked and I just swipe and I'm in the application whose notification I touched. The LG V10 has a fingerprint reader on the power button, but I haven't programmed it since I heard it's not that great. This is a major security issue in my opinion, and I haven't read any other posts anywhere about it. So I don't know if it's specific to LG, the V10 or Marshmallow (it started with Marshmallow).
I can start a new thread if you believe our lock screen problems are unrelated (enough). Just let me know.

Same thing happened to me. I'm THE ONLY one to ever use my phone and I went to open it and it was saying my pattern was invalid. I was able to use the thumb print pattern still though. However when I went to change the pattern in my settings I entered what used to be my pattern and it locked me out of my phone for an hour. I don't know how to change it.

Saw you had the same issue, so wanted to let you know. I restarted the phone and the old pattern started working again. Another person with this issue said that they had to restart several times, but it did work. So I'd give that a try, worked for me. Good luck!

It just happed to me. I restarted it and it accepted my pattern. I now have it set with pin instead.

Had the same issue as well! Samsung Galaxy S7, suddenly stopped recognizing my screen unlock pattern. Same solution as well; Restarted my phone and the problem went away.

Is there a way to disable the pattern feature if you are able to navigate the phone? Got locked out of Marshmallow on my MOTO G 3rd gen. phone after a pattern change; I was surprisingly able to just reboot into an unlocked phone. I've turned on adb debug access while I still have the opportunity.

I just had that issue. I was able to unlock with the pin, and reset the pattern and it now works again but it was freaky.

Same happened here. This morning the lock pattern on my S7 edge is forgotten by the phone.. Reboot doesn't help.

have the same problem today. i didn't change my pattern and it happened again. before i was using a PIN and I ended up factory reset and by this time I wouldn't want to do the reset factory settings as the last option.

The pin was also randomly stop working, I have mine set to pin and it did the same thing.

Me too!!!! Wtf!!
Mine has locked as well and I swipe the wrong pattern until it gives me the option to put in the back up pin but when I go to correct the swipe it wont let me in. I have tried everything all of you have suggested except the factory reset, I just can't believe that Samsung hasn't put out a fix for this yet.

Here is how you fix it
Method 1. Use 'Find My Mobile' feature on Samsung Phone
All Samsung devices come with "Find My Mobile" feature. In order to bypass Samsung lock screen pattern, PIN, password and fingerprint, you can just follow the below steps to get it done.
• First of all, set up your Samsung account and log in.
• Click "Lock My Screen" button.
• Enter new PIN in the first field
• Click "Lock" button at the bottom
• Within few minutes, it will change lock screen password to the PIN so that you can unlock your device.
tell me it work ??

Just an update to help out someone who might be going through this. This recently happened to me on my s6 edge.
Like the above comment suggests, go to "Find My Mobile". Once signed in, select the "UNLOCK MY DEVICE" option , (selecting the "Lock My Screen" option does not allow you to change the lock screen type afterwards).
Selecting Unlock my device will immediately unlock the phone and erase any lock screen patterns, fingerprints or pins that you might not remember, thus allowing you to set them up again!
Hope this helps!!

Also, one more thing. Doing the above ^ seemed to have solved a problem I was having with "Smart Lock" not working. So just as an FYI, going through that process might help you with that.

This just happend to my gf's s4 also she sent a text and then went to reply again a few moments later and her pin was invalid and it locked her out of her phone for 30 seconds, she just had to restart it once and it worked with the old pin again.

same issues here, pattern just stopped working. im positive im using the correct pattern.
i can login with my pin, but i cant reset the pattern as it keeps asking for the current pattern.
how can i reset the pattern or change to pin / fingerprint?
ive restartted 2x and trying a 3rd now....

> Use 'Find My Mobile' feature on Samsung Phone
No this didn't work. It still requires my pattern, and tells me I'm doing it wrong...
It DID let me into the phone, which was nice. But the pattern problem persists...
...Update: I restarted the phone, and it came up and accepted my pattern.

This just happened to me on my phone and my tablet. I wound up having to do a factory reset on both! Way to go Samsung. These are the last Samsung devices I'll ever buy.

Fingerprint While Screen is Off?

My wife just got her S8+, and we were trying to get the fingerprint sensor too unlock to the home screen the way her pixel would. The way it works now, she has to awkwardly reach for the sensor, then swipe up to unlock the device. Any suggestions, or are we out of luck unless Samsung devices to make this a feature in an update?

Did you enable 'Fingerprint unlock' in the settings? I'm able to unlock my S8+ while the screen is off just by putting my finger over the scanner without swiping anything.

I'm not sure of this caused it, but we ran a system update and it started working as expected. Again it may be a coincidence, but it started working right after the update. Mods can delete this thread of they want, it's not a relevant question since it seems to have been a bug.

Yeah, same here

How is the fingerprint unlock supposed to work? On my Nexus 6P, with the screen off, you just put your finger over the sensor and the phone turned on, unlocked. But it seems the S8 requires you to push the power button, then use the fingerprint scanner. Is that correct? Is there a way to have the fingerprint sensor turn on the screen?
(Yes, I do have "fingerprint unlock" turned on in settings.)

I don't have to push my power button to get it to unlock. I just place my​ finger over the sensor with the screen off and it works instantly and doesn't show the lock screen.

Don't delete it, I almost gave up on this option, reading this made me try again and it's much improved, thanks!

Interesting. I'm not sure what I'm missing, but I can't get mine to do that.
Edit: I may have bigger problems. I can't actually get the phone to lock. I have smart lock turned off and only pattern selected for screen unlock type, but I can just swipe on the lock screen and go to the home screen, without entering the pattern. I assume these two issues are related.
Further edit: OK, the second issue was because of the "secured lock time" setting. So, unrelated.

Well, I got it to work. It actually was the "secured lock time" setting. Basically, if the phone isn't actually locked (because the time in that setting hasn't passed), even though the screen is off, the fingerprint sensor won't wake it. But if more than the set time has elapsed, it does.
Not the best design, but that explains it. My advice: set the secured lock time to zero ("instantly with the power key or when the screen times out").

Hmmn, I have mine lock instantly via power button and tried it... Still works for me

I didn't explain it well. Locking instantly is the way to go.
For some reason, it's set up to use biometrics only if the screen is locked, not just off.

Posted this before but with all the setting correct.
You can simply put your finger on the sensor and it will unlock right to the home screen.
You need to habe the finger print unlock turb on.

This has to be my favorite feature on this phone, beside using it to pull the notification bar down

Does it work on s7 edge?
Is there anyway so I can unlock my phone when it's off using fingerprints?

This is the S8+ forum. You would get a better response in the S7 Edge forums.

Fingerprint

I have unlocked my lg velvet bootloader (g910hm) its the 4g model. And after doing that my fingerprint scanner stop working. So i tried to relock the bootloader but i cant even enter to bootloader mode in my device! Every time i tried it shows me a sing that i have to relock and restarts my phone. Can anyone help me? Because i want to use my fingerprint sensor again with or without the bootloader

Fixing your fingerprint reader
After the bootloader unlock, you will no longer be able to register fingerprints. This can be fixed using the following steps:
Launch the hidden service menu by dialing #*462633*#910# (might require an inserted SIM card)
SVC Menu -> Handprint -> HandID Logging "ON"
Go to the start of the menu and then navigate to "Device Test" -> SAAT -> Manual Test -> Optical FingerPrint Test
Press SEVERAL times firmly on the green button until it says FAILED, confirm and exit the menu
Go to settings and set up your fingerprints!
AFAIK, you can now disable "HandID Logging" again

sry for late reply (i dont check my mails). I actually ran into the same issue forcing me to do this what I wrote every 2 hours. I actually have no clue whats the problem and switched to a new phone. I can only recommend to root with magisk again and use all the plugins recommended there. I hope ur reader then works again.
