My LG G8 (LM-G820UM) Updated to Android 10 within the last month, and since the update I've noticed an issue with my device failing to actually lock when pressing the power button. The screen will go black, but when pressing it again to wake the device goes to my home screen rather than showing the lock screen. This issue is intermittent and I cannot pin down what causes this. My 'Secure lock settings' show that pressing the power key should instantly lock the phone. I do not have face unlock on, but I do have Hand ID and fingerprint unlock on.
Any thoughts or suggestions would be greatly appreciated in helping to find the root of this issue.

Hi,
I have a problem with my lock screen. If I lock my GS using the power button, the slide to lock screen comes up upon pressing the power button again.. fine no problem there.
But, if I let the screen timeout and the press the power button to bring the phone outta standby. There is no lock screen. I am brought straight to the home screen.
I cannot see, or have never come across and option to enable this. I had a look around the Q&A GS forms also. Anyone have any ideas?
(hope it's not something ridiculously simple I've missed)
what is selected in automatically lock? if there is for example 1 minute, and you turn your device in this minute on then there is no lockscreen, but after this minute the lockscreen is back
Ok I've played around with security settings and tried to find the "automatically lock" option. I seems this was not visible until I selected "pattern Unlock".
I set it to 30min at some stage and seem to have forgot about it.
When I set it back to "Immediately", the problem was solved.
Thanks for the reply, gave me a push in the direction I needed to go in.
This application blocks the ringer mode to avoid changing the mode when the phone is locked (screen on)
this is a workaround for the following strange behavior / bug on stock android 4.2+:
Note: my phone uses a pattern to unlock screen.
- Steps to reproduce the problem.
1.Lock the phone, and light the screen with power button.
2.Long press power button until the power off menu appears.
3.Press the power button to close the screen.
- What happened.
4.After that, every time the screen is lighted (but not unlocked), press the volume keys can change the volume though no music is playing at all.
The volume keys keep working each time I turn on the screen without unlocking, and it is back to normal when I unlock the phone use the unlock pattern and lock again.
- What you think the correct behavior should be.
The volume keys should not work at all when the phone is showing lock screen, it has accidentally muted my phone and led to missed calls. This is worse than power off menu it self. Since power off menu only appears with long press, but when ever the menu appears once, the volume keys work every time until I re-lock the phone.
And also I don't think the power off menu should appear by long pressing during locking state, since it is quite possible that the power button can be long pressed even in my pocket during taking the phone in or out.
P.S. When the phone is rebooted and went into lock screen the first time, the volume keys will work on lock screen without the necessity of showing the power-off menu.

How can I lock my phone if I decide to lock it, while the self-locking stuff is disabled?
I prefer to keep my phone unlocked. So I put a 30 minute timer to prevent the self-locking, and disable the option of "immediately lock when power button is pressed."
But if I get stopped by the police I want to lock the phone immediately. Any way to do that? Currently I'd have to hold the power button, and select restart or power off, then confirm it, and that can be awkward if you are running away.
Run faster than the police.

I never tested it that way to be certain. But I was using "Screen Off and Lock" on my last phone, because the power button was getting flaky. So I used the SO&L shortcut as a substitute power button to turn the phone off. Then I'd wake it up with the Home button.
I believe SO&L would lock it immediately, even if normally it would not lock right away if I had used the power button.
Maybe give it a shot?

If we answer this, could we be charged with assisting a felon?
Just kidding about anything nefarious, hope it brought some smiles?
But the point remains. If I want to lock the phone occasionally, but generally keep the phone unlocked, I don't see a way to do this on the phone without resorting to aftermarket apps?
I think vanilla Lollipop android has the option to lock the screen when you are on safe tether, but that's disabled for me on the G4.
If you are worried about the police searching your phone have it auto lock when you push the power button and have it lock on a short timeout.
Hello. I have got a brand new S9. I got a problem - when phone is locked (without using Always On Display), and i want to unlock it (so i press unlock button), after pressing the button i have to wait for some 1-2 seconds, before screen wake up totally (for this 1-2 seconds screen slowly brightens) What is wrong? Bixby is switched off, phone has got brand new and updated software, and i've installed just 4-5 app's. When AOD is turned on, screen woke at normal speed (quickly)
Some info about the phone (from settings menu)

EDIT: At the "Safe mode" screen woke up instantly right after pressing unlock button..
I have the same problem! The phone wakes up very long.
Make sure in LOCKSCREEN AND SECURITY / Secure lock settings, your phone is set to Lock Automatically "Immediately". This will immediately lock your phone when screen turned off and then you can immediately unlock it without delay.
Hi all,
I noticed that sometimes when I try to open the secure folder on my Note10+, the phone does not show the unlock options, but just a blank screen with a back button. The back button can be tapped but does not do anything. I am not able to swype down from the top and bring up the notification bar. When I turn off the screen and/or lock the phone by pressing the power button, I can unlock the phone itself, but it then takes me back to the blank page. So far the only way I am able to get out of this situation is rebooting the phone using the power button (which still responds).
I have the firmware up-to-date (september security patch). It is an unlocked european version, and I use a pattern and fingerprint recognition.
I was able to screenshot the state. The screenshot itself is already placed in the secure folder. See attached.
Anyone else who encountered this issue?
