Lock screen disappeared, can't get it back.. [solved] - Nexus 4 Q&A, Help & Troubleshooting

EDIT: IT WAS QUICK SETTINGS; I AM RETARDED.
I'm running CM 10.2 nightlies. However, nobody else on the same version is reporting this problem:
In settings > screen security: set to 'Slide'.
I have tried Pattern and PIN, as well. Nothing brings the lock screen back. When I turn on my screen, it goes straight to whatever was on the screen when I turned the screen off.
What could be causing this? I've tried several different nightly versions. Profiles are disabled. I've tried looking through settings many times, and googling, to no avail..

I know it's not a solution but you could try a lockscreen replacement in the meantime like widget locker or milocker?

Thanks for your reply, but I'm actually trying to determine the cause of this specific problem of the CM lockscreen...

[INFO] Wake up from standby fix!

Well those of you like myself that were having the issues of hitting the power button only to see a black screen, here is all I did and its been working flawless for 24 hours. Turn of the screen lock! I haven't tested other screen locks yet so maybe its just the default one
If this dose not work for you please post.
Trying this myself now. It had previously happened 3 times to me with the default lock screen. If this does work, that sucks cause I really liked the lock screen... Does anyone know if either of the firmware updates addresses this particular issue? I haven't done them yet was waiting for the new root method which was just released yesterday.
maybe that's why i never had that problem... i always had a pin from day1
I am updated to the latest firmware and the issue still existed. Are you running a battery monitor widget?
turning off screen lock didn't do the trick for me
what worked for me is disable wifi before turning the screening off or go into option and change it so that it never disconnect from wifi will fix the issue for me though

Unable to get screen lock back

hi! i'm using ezet's cm7 .32 rom. my problem is that i can't get my lockscreen back, my screen just won't lock anymore. i'm not using any kind of security (gesture, pin, password), just the simple default ring that i have to slide to activate the screen. yesterday i've been messing around a little bit with the screen time-out settings in cm settings, with security settings and so on, but then i reverted everything back to my usual default settings, at least i think i did, and now my screen won't lock. my time-outs for screen lock are set as before, at 30 sec, but i doesn't help if i change the value to immediately or anything else... whenever i turn on the phone, there is no screen lock, the screen is active whereever it was when it was turned off. i went through all the settings for a 100 times, but i can't find anything different from before, no setting which would prevent the screen from locking. i reinstalled the rom, wiping cache and dalvik cache, i wiped cm settings app's data, i restored a backed up version of cm settings app with titanium backup, i have no other ideas why my screen wouldn't lock anymore. i'm thinking about reinstalling the rom and wiping the data, but i'll do that as a last resort... does anyone have any ideas, what else i can try???
thanks in advance!

[Q] Cyanogenmod 10.1(.2 or latest nightly) - Lockscreen Problems

Dear all,
a few days ago I started again using Cyanogenmod, first latest stable (10.1.2) and today also latest nightly.
In Settings lockscreen is enabled with cLock-Widget, till now I tried normal unlock (move only), pattern, PIN and Password but in 90% of all cases, if I switch of my Nexus with Power, it is NOT locked. Pressing Power again, after a few seconds, minutes or just hours still show homescreen oder latest app which was open. Same if I do not use Power but waiting for automatic Lockscreen.
Do anyone has the same problem or just know how to fix that?

What are your settings for under Security for:
"Automatically Lock after ## after sleep" and do you have "Power button instantly locks" checked?

I just went back and used Widget Locker again, no more problems with that.

I've noticed this as well. Since around the time of the 10.1.2 release.
Basically, I've changed the default settings so there's a lock screen and it works at first, but then, seemingly randomly will stop working, ie no lock screen whatsoever. I can leave the phone for hours, and there's no security.
Seems like a pretty serious flaw to me. I've actually upgraded my CM installation, as well as done a complete reinstall, doing a factory reset, and updating to the latest nightly, ie last nights, and this issue is still there.
Basically means I can't rely on CM for keeping my phone secure. I've changed the settings back and forth, tried different security settings, reset things, reinstalled, etc. Tried everything I can think of.
Yes, all the proper settings are there, basically CM's default settings once you turn the lock screen on should work, power button instantly locks, timeout etc.
About ready to go back to an earlier version or different rom completely.
Anyone have any thoughts?

I just loaded my first rom on my Note 2 today. Getting the same thing. The quick fix is to close all the open apps, then it kicks you right back into the lock screen. I double click, then button in the top right and closes them all auto for me. I think it might be FB Messenger causing the issues but I can't say for sure. LMK if you that helps in the short term?
Am not running FB Messanger, so that's not causing it for me.
I'm using a pattern on my lock screen, not sure if this issue exists with all types of lock screens.
Hi all,
I've just installed CM 10.1.2 on my SGS2 (GT-I9100) yesterday and I had the exact same problem.
I've just figured out where the problem is:
I use Handcent SMS app, and when I receive a text, a quick reply window pop up. If I type my reply in it and hit send, it deactivate my lock screen.
Hope my answer helps!
I have the same issue. Disabled the popup function in Handcent settings and lockscreen i working.

Help! Several major issues on 4.3 (home button, SIM, lock screen)

My N4 was away to repair a broken screen. Got it back on Wednesday and it immediately updated to 4.3. All was well, except for one weird issue where hitting a notification from the pull down would take me to the app via the pattern lock. I put this down to having played with some lock screen settings in Setting Profiles app (trying to disable it in certain settings), but it might not have been.
I've done the first device restart today, and after rebooting there are a few big issues.
1. I don't appear to have any mobile network, though wifi is connected. I had a good signal before the reboot.
2. I'm not getting a lock pattern or any lock screen at all, and it's not asked for the SIM pin
3. Hitting a notification in the pull-down makes the 'lock' clicking sound as it takes me to the app
4. The home button doesn't work. I see a slight dim of the screen and it makes the lock click sound, but nothing happens. Back and multitask work fine
Help! Any ideas? Are they known issues? Can't seem to find any reference online.
I'm on stock, using Nova Launcher

Those are not any known issues or anything I have read since Andrid 4.3 came out. Try a factory reset to see if that solves the problem. If not, maybe the screen wasn´t the only thing broken on your device. Ask for warranty.
Thanks, will see how I get on this evening and try a factory reset if it doesn't fix itself.
Seems to be a weird problem related to the lock screen and when it should/shouldn't kick in...

Glad I could help.
Ok, I've done a factory reset. Not had much chance to play as it took hours to reinstall everything. But I've just had the word issue where selecting something from the notification tray (the setting profiles shortcut) took me to the lock screen to put in my pattern first, then took me to the app.
EDIT no pattern to when it does it, seems random and can be while I'm using the device, so the lock screen shouldn't kick in for any reason
Any ideas? Faulty device?

Remove Lock Screen from Android Head Unit

Hi,
Just got an Android Head unit. All was working well until I installed Bit Defender. I stupidly tried the anti theft function (Which sets a "one time" pin on the device).
Problem is I now need to enter a pin every time i start the car. Its some how turned on the android lock screen and I cant see how to remove it.
Any ideas? I >think< this is the standard android lock screen rather than something bit defender specific. Uninstalling Bit defender does not remove it.
Tried contacting the seller who advised not to perform a factory reset. Looking at other posts it seems others have performed factory resets... What (Apart from normal apps etc) will i have to set up again if i do so?
Thanks very very much for any advice. This is driving me crazy.
I also had the problem once and i had to do a factory reset. But if you use titanium backup it´s not so bad.
Screen lock Allwinner QUAD CORE T3
I did the same exact thing using Find My Device, thinking that the password is not changeable but removable so the only solution to get rid of the password each time the car starts is to hard reset it?
Hello, did you manage to solve the problem?
Hi again, I also set a password and I can’t disable it, this is bothering me a lot, did any of you guys find a solution? Thank you in advance for any and all help!

How to hard reset android head unit? can any one pls help on this.
Solution for this for me is Quickshortcutmaker. When you start the app, then search for the app that's called search suggestions. And open it.
Now you can search all possible settings in android, which often are hidden and not accessible. Try secure or something like that, to access the lock settings and there you can remove it.
Thank you, I will try this today and report back. Will it require root?
No root needed
Hey sorry to bother you again. I tried it, but the app just takes me back to PIN settings on Android settings which is grayed out and not clickable. Can you tell me what I’m doing wrong? I’m a noob and not sure what the purpose of this app is to begin with. Here is a 40-second video I shot about what I did, below. Thank you for your help, I appreciate it a lot and don‘t take it for granted.

Strange, for me it is working. My PIN bar is active, when i click on it. It asks me for my PIN.
Can’t remove screen lock
Hi everyone,
I am having the same problem - I cannot remove the screen lock / pattern set up on my Android car head stereo device. I have tried all sorts - going into advanced settings and turning off the ‘screen lock service’, turning off ‘find my device’, removing my google account.
It is so frustrating having to type this in every time the car starts!
I am currently in the process of downloading QuickShortcutMaker. Will keep you updated...
I was in my car trying to solve the problem when you posted your message, and I think I solved it!!! I just cleared credentials and the PIN went away. Go here: Android settings / Security & Location / Advanced (Trust agents), I can’t see what’s next because once you remove the PIN it doesn’t show you the menu, it just says “To use, first set a screen lock”. But somewhere in there, there is “Clear credentials” which did the job! It didn’t affect anything else as best as I can tell, but it’s been only 2 minutes since I managed to do it.
Hi!
I’m currently on quickshortcutmaker and can’t find what you’ve found. Are you on this app?
Thank you so much for your help by the way! I feel like I’m close
There is “trusted credentials” on here tho
No, I didn’t use the quickshortcutmaker, I did it through the Android settings. Here’s a video of what I’ve done, your setup may differ but this is the general idea:

Maybe it's a ROM issue. I use Malaysk ROM.
Contrary to the topic starter, I found this thread because I wanted to have a lockscreen. I don't like the idea that when my headunit might get stolen the thief can view all kinds of personal information.
So I tried quickshortcutmaker and I could enable it. So far so good.
However, with the screen lock also automatically came a screen timeout which is set to about 10 seconds. So every 10 seconds the screen goes blank. This is of course totally unacceptable for a car head unit. The screen has to stay on until I turn it off.
Unfortunatly I haven't found a setting for the screen timeout. And about the screen lock: you can turn it on and choose different methods, but you can't turn it off. The option to turn it off exists, but it just doesn't work.
I had this problem yesterday and just figured out how to fix this. Deleting the Credentials and disabling through the regular settings menu does not work. Everything would just revert back, so I downloaded an app from the Play Store called Android Settings X. There you can reach the hidden settings. Choose "Choose screen lock (SetupChooseLockGeneric)" to remove the Screen Lock. If that option doesn't work there is another one, 2 options down, called "Settings (ScreenLockSuggestion)". Remove the Lock Screen here. Bam, fixed! This is the only way I know of that actually removes the Lock Screen and will not revert back.

You might try Android Settings X as mentioned in my reply to the thread. Even though you have the opposite issue, i.e. wanting the lock screen, I'm pretty sure I saw a screen timeout option in this app, and since normal methods did not work to remove but using this app did, you might try it out.
