Great...... Got this message appearing and can't rescan a fingerprint I need to. Can't do anything with the scanner now really. It still works with the prints that are scanned but I've noticed it's unpredictable.
I'm trying not to root this phone as I would like to use Samsung pay when it comes, so don't want to trip Knox. However, if I was rooted I reckon this would be a fairly easy fix. As it is, I can't find a way. I've deleted cache and data for the fingerprint app but it's having no effect. I could factory reset but this started for no reason, so it will start again after a factory reset no doubt.
Did you reboot? What carrier/model do you have?
Clean the button?
Reflash your firmware that should fix it use smart switch
In case this happens to anyone else - I found a fix.
I had enabled developer options and then enabled oem unlock. I had done this as I was going to install TWRP and then root the phone, but decided not to for reasons mentioned in my first post.
Anyway, I disabled oem unlock and developer options and now the scanner works again. Worked for me - hope it works for you.
But oem option not see in my phone s6 edge G925W8

Something strange and unexpected has happened with my Nexus 5... Upon first setting up my device after unlocking it and rooting it, I encrypted the phone before ever adding any of my info or apps to it, full knowing that I would forever have to use a locked screen etc. To side step the annoyance and lack of security that Android has with having the Encrypted boot time password being the exact same as the lockscreen's password I used this app 'Cryptfs Password' to change the boot time password to something much more lengthy and secure, while allowing me to have a standard simplified passcode for simple screen unlocks.
As time went on I found myself in need to wipe the device to troubleshoot an issue I was having with my wifi and wireless tethering no longer functioning properly, I wished to go back to an initial factory state to begin doing restores from Titanium to find the culprit per say and figur eout where I went wrong and borked my ability to toggle wifi.
Upon wiping the phone in TWRP (standard dalvik, cache, and ROM - not system or data) I rebooted and flashed my Titanium Backup.zip and Super USer.zip and then proceeded to set up the device again when I noticed something very odd...
I still needed to enter my previously exact password upon booting the device, however the lock screen no longer any security of any kind!
When I checked in settings this is what I found:

Clearly you can see the device is still encrypted however the default "slide" screen lock is now able to be used? Whaaaaat?!?!
Opening the Screen Lock settings menu reveals:
https://i.imgur.com/FtOqUY5.png
I have not yet sleected to change it to a PIN or PASSWORD as I am home and wanted to see if I could gather any other information about this first. I have a feeling that upon changing to a PIN or PASSWORD that I would not be able to change it back again.
Is this a flaw or error of some kind? I do not see any huge security vulnerability, I mean even though this does allow you to bypass the lockscreen, you still need the password at boot to even get into the phone or any Recovery - but this is interesting nonetheless. I was under the impression that it was IMPOSSIBLE to have both device encryption and essential NO LOCK SCREEN?!?!
I have seen threads such as this one: http://forum.xda-developers.com/showthread.php?t=1873700 where it is shown and discussed how to use the pattern lock for example, but this is obviously much different.
Can anyone else replicate this with their own android device?
EDIT:
Was able to find this thread https://groups.google.com/forum/#!topic/android-security-discuss/G4N5pBreyhM
where someone was able to essentially achieve a similar situation by using a 3rd party lock screen....
I'm having an issue getting into my lock screen and security settings. Every time I try to open it, it crashes. I can get into every other setting besides lock screen and security. Also can't use the search feature without it crashing. Galaxy S8+here. Anyone know a work around without having to factory reset my device?

strange,
please give more details
I'm having the exact same problem on my s8+. Cannot use search function in settings menu or settings just crashes. Only discovered today actually, that I can't access lock screen and security now. Clicking on lock screen and security causes settings to crash. Have you been able to fix this? I really don't want to have to do a reset.
try safe mode so you can find out if it is caused by an app
If you forgot the login password , you can not access your phone
I'm having the exact same problem. Only noticed after installing bixby and it recommending setting up smart lock from the lock screen and then not being able to get in to the settings. Was working fine when I used it just a couple days ago, not sure if bixby has anything to do with it but have tried wiping cache and safe mode with no luck?
Edit: so just after getting a new firmware update the problem seems to be fixed. Not sure if this was an actual issue with the old firmware or any update would have fixed it.

So this has actually happened to me 2x. It's effecting my phone currently. The first time it just kinda fixed itself after an update thru T-Mobile. Sucks. Can't use Google Maps or Inbox at all either. So frustrating.
My settings crashes when I go to set "Emergency Alerts" and the Advanced settings in Mobile Hotspot. Wiping cache doesn't help. Anyone else have this happen?
Hey everyone, like an idiot I was disabling some bloatware via ADB (through ADB App Control) and was not careful enough...I'm now facing a serious problem.
For my lock screen, I am still using the old school method of a pattern and after rebooting the lock screen comes up. The problem lies with the fact there is no area in order to enter in the pattern and am locked out of my phone.
Some of the packages I got rid of are overlays which I'm guessing is where the problem came from. Does anyone know exactly what packages I need to restore to get the lock screen back up and running again? Thanks in advance
I'd just undo everything you did, then you'll be sure to get it back.
otherwise just flash the firmware over itself to restore all those system packages that you disabled.
This is why I never debloat. it's just not worth it, and it more often than not causes problems.
I never made a note of the actual packages I disabled because I just did it though ADB App Control. You can easily restore them back but only if the phone is unlocked which I can't do now because of this issue.
Is there a list of all of OnePlus8T's preinstalled packages? Can't find one online anywhere....
Though I know flashing the firmware is the sure way to fix this, I'm looking to only do this as a last resort with all the work to setup the phone would take me again.
Is there a way to flash firmware over the top without wiping data on OnePlus? I know there is for most other OEMs.
I can't unlock my phone with the Pattern I assigned it. I always use the same Pattern, so I was pretty sure it's not an error. When I draw the pattern, it says "incorrect pattern" and makes me wait 30 seconds before trying again (from the first try).
Luckily, I have access to Samsung's Find my Mobile, I unlocked the device, removed the lock. But every time I restart the device, the bugged lock screen would come back, and I would have to unlock the device again with Find my Mobile.
please note that I can't set a new lock after unlocking the device, it will revert back to no lock after setting a new pattern/pin/password. definitely a bug.
if there is any method to fix this, or to reset Samsung's lock screen app, please let me know!
my device is Samsung Galaxy A8+ in case anyone was curious.
I never set a lock on a phone or bios password on PCs... now you know why.
You're lucky it was recoverable... some lockouts are not
Data corruption can trigger this and it's just random luck if it happens or not. Even if rare you can see the implications. You're now very close to being completely locked out as it stands
You can try a clearing the system cache and data from the apk(s) controlling it.
Try a hard reboot.
Factory reset... if that fails it's probably hardware. Or simply keep it unlocked and in your possession at all times which is the best security.

I'd like to keep it unlocked, yet as I mentioned, it will spring back again immediately as I restart the phone. It won't be funny to get my phone locked outside my home and not having a pc near to access find my mobile to unlock it
I'm trying to avoid factory reset, too much data to back up and I'm quite lazy to do it
And it seems like there is no way to clear cache/data, as the Samsung's lock screen doesn't appear in storage/apps. (Or it is there with some strange system name?)
This thread may help you as it helped me. Read the full thread first.

Oh my bad, it locks no matter what. That's not good.
Boot menu>clear system cache (don't hit factory reset by accident).
Google for the button sequence to hit for that model. Timing is critical, you might need to try more then once.
That might get it.
Try clearing the Dynamic Lock Screen data.
I would backup all critical data now if you haven't. Do not use Smart Switch to transfer settings if you do factory reset, ha-ha.
Someone here probably has a better solution as I know little about this system.
As always do a Google search, you can probably use solutions from other Samsung models going back a few years.
Erratic and strange behavior can also be a sign of a virus, rootkit etc.
When in doubt, factory reset especially if you can't track down the root cause.
Finding the root cause and correcting it is always preferable to a factory reset but not always possible. If the OS load is older then a year a factory reset be a good plan anyway... nothing like a clean, fresh OS.
Delete your Google account before you factory reset so that doesn't password pester you. I'm told if you reset from settings vs the boot menu that doesn't happen. Not sure haven't tried a factory reset that way.

I read if you load TWRP you'll lose things like Samsung Pay.
Seems risky at least to me. I like to play with it but don't have a phone to burn.
A factory reset for me at this point is fairly painless ie no data loss and takes under a couple hours.
If it's of any interest here:
On Android the pattern lock data (SHA-encrypted) is kept in a file named gesture.key and stored in the /data/system folder.
If phone's Android is rooted you simply delete that file to bypass the pattern lock. Using ADB you would run command sequence
Code:
adb devices
adb shell "rm -f /data/system/gesture.key"
to achieve this.
The phone should be now accessible with no pattern lock applied.
Hi all!
I've been searching for a solution for some time but couldn't find any.
Always On Display stopped working on my Pixel 6a. It's all turned on in the settings but it simply doesn't work. It works only in those cases:
1. When device is rebooted into an Airplane mode
2. When device is rebooted into the Safe Mode
3. When device is rebooted but not unlocked for the first time
There are also no notifications displayed so screen wake on notification doesn't work. Same story as above.
I thought there is some app blocking it but couldn't really figure out which, I tried to disable many of them but none helped.
I did a factory reset once but issue came back after few days.
I seriously have no idea what might it be. Hope someone here might have had similar problem and found a solution.
Thanks!

Would you be down to try flashing a custom ROM?
I've read in another thread not long ago someone saying their Tap to Wake randomly stopped working. We narrowed it down to an issue with the proximity sensor (so the phone thought it was in a pocket/covered, therefore didn't let Tap to Wake work, he had to use the power button to turn the screen on). He then flashed a custom ROM (it was LOS, I think), and that solved the issue for him.
I've also had some issues with the stock ROM, flashing a non-factory one solved all of them
If you want to keep on using the factory ROM, you might wanna try using the Android Flash Tool instead of just factory resetting to make sure no corrupted settings can live on.

I would say it does not have anything in common with the proximity sensor since it works fine with airplane mode turned on. I want to stay with the factory ROM. Maybe it's an issue that will be fixed any time soon?

Why do you ask for advice if you just want to "wait for it to get fixed"?
If you've done a factory reset already, it's not a hassle re-flashing the factory ROM (since you already have your data backed up).
Fwiw, the guy with the proximity sensor issue also had it sometimes work and other times not, much like your issue
