S4 locks even with "lock instantly with power key" unchecked - Galaxy S 4 Q&A, Help & Troubleshooting

Hello Guys,
I have a S4 I9505 international with ZTO (Brasil) I9505VJUGNE2 firmware.
Today, after some screen locks issues, I decided to do a factory reset.
Everything works well, but I realized the option "lock instantly with power key" does NOT work anymore.
Even this option unticked or lock automatically set to more then Immediately, the phone goes to lock screen after timeout or after I press the power button.
In other words, if the screen turns off, the phone locks.
I've tried another hard reset, set/unset/change all relateds lock functions and not works.
The only way to get the phone unlocked after screens turns off is set Screen Lock to NONE.
Anyone have an idea to fix this?
Thank you very much.
UPDATE: The problem is solved when KNOX are configured. If I reset KNOX data or disable KNOX app, the problem returns and remains.

I am having the same problem. It only appeared after a recent update which added the Kids Mode feature (which I did not install). WTF samsung... stop messing about with basic features and fix this bug. I do NOT want the power button to instantly lock my phone...
Can you please explain how you fixed it? I never downloaded knox on my phone. Do I now have to have knox to resolve this isse?

Knox is like a virtual OS inside your actual android system. It was developed by Samsung for corporate and security purposes.
You can see more detail regarding here: http://forum.xda-developers.com/showthread.php?t=2595889
If you have a oficial Kit Kat 4.4.2 from Samsung, you already have Knox, to setup it, just launch knox app from app drawer, choose a security option, put your password and you are inside Knox (if some files are necessary to run, setup will ask to download. Stay on a wifi at this point).
Thats all... play with Knox... for me, after this procedure, the lock behavior returned to normal..
Good luck

[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'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?

[Q] Screen won't turn off

For some reason my screen won't shut off when I press the power button or by itself after any amount of time. I made sure all of the settings were set right that might keep it on. I know it's not hardware damage because I've pretty much never dropped it or handled it hard. The power button still works because it will get the turn off, restart, etc screen to go. Any idea how to fix it? I already did a factory reset.

Download wakelock detector and see which app is keeping your screen on.
Dialed that number, the dimming worked, but the sleep button didn't do anything. I'll try that app out and see what it says.
In my understanding *#0*# dialing is for hardware check, if sleep is not working from there means it has nothing to do with any app & better to take to service centre.
Sent from my SM-N9005 using XDA Free mobile app
It didn't do it until after I tried to change my boot screen. Know if that would do anything? No boot animations go off besides the galaxy note 3 one (no Tmobile or samsung animation, and no shut off animation). I also rooted it so would they still help me even though the knox counter is 0x1?
Any help? Using the wakelock app it says that system manager application is used a lot more than anything else. Not sure what it does.

Try to flash complete stock ROM & clear Data & Catch before & after flashing from recovery may HELP.
That fixed it. I'm not sure why I didn't already try that since it seems kinda obvious. Don't know what made it do that though. Do you happen to know if modifying the boot animations can mess other things up?
Mine its not rooted still stock and all of the sudden started acting up with the screen ....i did the *# test and when i went to sleep it went straight to the lock screen ...any idea what could cause it

Mine does this every time I reboot my phone. I have to press and hold the home key, pick the pie chart, pick RAM and pick "Clear Memory". Then it's fine til the next time I reboot.
I had my note 3 with the same problem and solved it recovering the original system/media/bootsamsung*.qmg files.
to solve the problem plug the charger and unplug it immediately and plug it back in again. This is also the reason why the problem is caused. So doing it again will solve the problem.

After latest update, weird lock screen behavior

Ok,not sure if it's the new VZ update ( VS980026A) or StumpRoot (the only way I could root after this update), but double tapping the phone or using the power key to wake up the phone shows the lock screen and immediately shuts off again.
It wasn't doing this before, and it's intermittent. Is there any way to debug that? I may have solved it by setting the security lock timer to 5 seconds instead of the default "immediately", but is there any way to debug this?
I didn't have problems til this update. Maybe I need to dump the VZ ROM and load something else. Any suggestions on the best ROM?

S7 Edge Lock Screen issue, wont unlock

I bought two Galaxy S7 Edge phones recently and have noticed this issue on both phones now. Both are also updated to the latest firmware. Both of us have fingerprints set up and a pattern backup. So far, the issue has occurred to us both twice. I happen to always use my fingerprint to unlock and she always uses pattern out of habit from a past phone. She brought it to me a couple of days ago and said her phone says to wait 60 minutes and try again. I asked how many times she entered it wrong, because of course I thought she entered it wrong. She said she didn't enter it incorrectly. I asked if she tried to reboot, of course not. Anyways, I held on to it and after 60 minutes I entered the pattern to unlock her phone and sure enough it wouldn't work. I rebooted, and tried again and it worked. OK...Weird.
The very next day, it happened on my phone. I always use my fingerprint though so it told me no match found. Say what? Tried again. Same thing. OK, swipe and tried my pattern. It says its incorrect and to try again in 30 seconds. 30 seconds later, I tried again and it locked me out for 60 seconds. This time I rebooted, and after it was done and 60 seconds had passed my pattern was working again.
I don't get why it randomly seems to not recognize that we are putting in the correct pattern or fingerprint. I am however happy that a reboot seems to resolve the issue. Is no one else experiencing this?
Mine doesn't lock instead!
So I tried couple of things. Rebooted, re-initialized Finger Prints and even pattern. Now matter what I do, it won't lock the phone. It will just unlock without asking for passcode, pattern, password or fingerprint. Only option I can think of is to restore the phone and try setting up lock option but that's pain in the a**!! I tried third party apps as to lock screen but none of them have the fingerprint unlock option! And some have ads and weird setup which worked... Gettting frustrating. Perhaps I should try restoring phone if there's no other option left

Entirely different. I'm not sure this is actually an issue as much as it is probably settings. Go to settings, Lock screen and security, Secure lock settings. Check how long Lock automatically is set for (mine is for 5 seconds after the screen turns off automatically and that is set for 2 minutes.). Then turn on lock instantly with power key. Go to smart lock and see if that's being used. IF it is it would keep your phone unlocked when its connected via Bluetooth to a device you told it to trust, or when you are at a trusted place via google maps (such as home or work), or it could simply know your voice, or lastly if it senses that it is on your body (I don't get this one. Seems very insecure, like anyone could pick it up and it would just unlock.). Good luck!

Forgot to mention, have done all of that. First I had it set Lock Automatically to immediately and tried 5 seconds, 15 seconds to all the 30 minutes, still won't lock (over night till I wok up in the morning)
Smart Lock:
Trusted Device are my car and my watch, but even with bluetooth disabled (just to give it a shot) it still doesn't lock.
Trusted Place: my home, but even with Location Service (GPS) turned off, still won't lock
On body Detection = Off
Trusted Voice = Off
Tried updating phone perhaps something may fix it, nothing.
Tried Security Policy updates and that says ... updated to latest version...
Been using Android since good old HTC Evo days and had no issue with my (last) Note 4 locking with fingerprint!! I love this phone really expect for this issue. Oh yes and another issue, gestures won't work also!!! Tried hand gestures for screenshot, nothing. Smart Stay doesn't work also!!!
Is something wrong with this phone perhaps??

Hmm.. Have you tried turning off Smart lock all together? Otherwise, all I can think is to factory reset settings before you factory reset the phone.
Factory Settings Reset did it
Factory Settings Reset did it however gestures and smart stay are still issues!! Then I courage myself to do Factory Phone Reset and dang the issue with the gestures persists!!
Bump.
No one else is having this issue? I just happened to be the only one with two new phones that do it?
This literally just happened to me! I was walking to a friend's house and was using the phone just fine - was using Facebook Messenger and Spotify. All of a sudden, I try to unlock it (I have a pattern to draw, not a code) and it doesn't work. I have no idea what's going on but I don't want to factory reset and lose all my contacts and pictures. I only have four tries left to unlock it before it automatically resets itself. I've tried using the Android Device Manager to set a temporary password but since there's already a pattern to draw it won't bypass the lock screen for some reason. I never thought to check the security settings on my phone (why would I if I had a lock screen on it?) so I can't use the Samsung equivalent either. I'm extremely frustrated - been looking for help for about an hour and I'm finding absolutely nothing. It's clearly been a problem before and yet there's no solutions or explanations as to why it's happening??
While I am still having this issue sparsely, I can get around it simply by rebooting. It's just annoying to have to do so.
It's anew feature of S7 called SMART LOCK, meaning your phone knows if you're in a safe place such as your Home, your Car or if you paired a smart watch with your phone and added it as trusted device, as long as you're connected to your watch, the phone knows you're in a safe place so you dont need to enter password to your phone. Or if youre in your car or at Home, then you wont need to enter password to open your phone. But if you want to remove this feature and want to swipe or enter your pin no matter where you are then do this..go to:
SETTING>LOCK SCREEN & SECURITY>SECURE LOCK SETTING>SMART LOCK. Here you'll see "Trusted Places" and "Trusted Device" Just edit or press and hold whatever is in there, e.i your watch, your home address etc...then remove and you should be good to go.
Have you tried turning off Smart lock all together? Otherwise, all I can think is to factory reset settings before you factory reset the phone.
