Yea...started happening to me a few days ago. Try totally disabling the lock screen, and see if it stops. If it does, you can enable it again. Are you using the regular slider lock screen? That's what I was using when it happened. I used face unlock for almost 2 days, and it never happened. I'm not running any lock screen now that I'm home, and its fine. Its just weird that it randomly started happening...I've never used a third party lock screen or even messed with the default settings for it to happen.

Yeah im using the stock lock sliders. I'll play with the lock sliders tonight when I get home and see how that goes.

screen won't stay off while: navigation only

Sometimes I want to turn the screen off temporarily to save power while using navigation. Now when I use the power button to turn the screen off, it only turns off for a second, then pops back on. This only is happening in navigation mode - screen will stay off otherwise. Any ideas?
I'm on Orange Glacier with the latest faux123 kernel...tried fixing permissions.
Same thing happens to me. I haven't bothered to check though. Maybe it is made to stay on in Navigation mode.
Check settings in navigation app probably made so you wont accidentally turn it off while driving then have to fiddle with it and risk a crash

Well my bad I guess. It looks like this is how it operates stock too...I could have sworn I was able to turn the screen off during navigation in the past, but must not have been able to.
I have checked and no such setting in default navigation for screen on and off.
I was just guessing I have a seperate GPS and only use nav when I'm in someone else's car and they're lost lol

Same thing happening here since recent update. It's not ROM-dependent, and I haven't figured out how to disable it.
I don't mind if screen timeout is disabled, and actually prefer that, but in this case I'm pressing the power button to turn the screen off and it repeatedly turns back on immediately.

[Q] Strange Lock Button Behavior

Hi guys,
I've been using the Optimus 7 for a few months now and recently I noticed this strange behavior. When i pressed the power button immediately after I turned the screen off, the display still remains off. I had to wait for a few seconds, then press the power button to get the screen back on.
Does anyone notice this strange behavior? On other phones the screen just turns on/off immediately after the button is pressed.
I too. But I think it is normal...

There is a purposefully implemented 1-2 second delay. It is a "feature". HTC WP7 phones do this as well.
Sent from my LG-E900h using XDA Windows Phone 7 App
is it possible to disable that 1-2 second thing? Must be in the registry somewhere.

Should I be worried?

I went to check something on my galaxy s but it wasn't responding. I tried holding the power button and tried to get it into recovery and download mode but nothing happened.
I then removed the battery and put it back in and it turned on as normal.

Known sleep-to-death problem. It happens on all ROMs I have tried on my phone. Happens more after a phone call. I was recently on holydays on another country and turned phone off, to use the SGS as a GPS navigation device only and I could suspend and resume it and use the GPS all day and it does not hang.
Just make a call, let it go to sleep and it may not wake up when you press the home or power button.
You don't have to remove the battery, just press the power button 10 seconds, phone will reboot.
I didn't make a call though. I was just on facebook then went back to the homescreen and locked my phone using lock screen widget which I have been using for months without a problem. A minute later I went to unlock it and it wouldn't respond. I tried holding the power button for atleast 8 seconds n nothing.

Pile of ****. Does NOT happen on all roms. It may happen on all roms you flash. More likely a problem with your phone, or user error.
Post the roms and your route to flashing, and then we will be able to advise.

Mines doing that as well. If I wait maybe like 3 seconds or so and press the unlock button, then it's okay. But this isn't that much of a repetitive issue for me. It's just random.
+1 exact same problem.. I think the lock is delayed..

i dun really think thats the case...
Lockscreen: "You wont like it when i am angry" - Quoted from................. Incredible hulk.....
Actually you can set the delay time with ICS now. It's located in Settings --> Security --> Lock automatically. I set mine to 30 seconds...
Otherwise: No problems whatsoever here...
Something strange happened to mine on Friday, I wasn't able to reproduce.
Basically when I turned on the screen I got the lock screen, pressing power again I went straight to home screen, pressing it again went back in lock etc. Weird!
I disabled it in security and re-enabled it and it seemed to have disappeared.
Any fix. For the lock screen issue guys

Flashlight shortcut from lockscreen?

So I discovered this purely by accident.
I've picked up my phone at night a few times and have blasted myself in the eyes with the light of my camera. It acts light using the widget to toggle it to act like a flashlight. Thinking my phone bugging out I thought nothing about it. But after the 5th time I decided it was a built in feature.
After much trial and error, I have these results:
With your phone on and screen timed out (turned off), press volume up and power at the same time. The screen should turn on, as well as the light on your camera.
To turn off let the screen time out, or press power to turn it off. Then press volume down.
Now I do not know how it works on mine but not my wife's note 3. I'm running stock Rom rooted with no mods.
I will try and figure out how I have this working, but any insight would work too.
Does anyone else have this feature?

I know Wanam Xposed has a feature for using volume up while the screen is off to turn on the flashlight, maybe that's it.

Well we're on this topic. I'm stock rooted on mje. What's the best way for me to add the flashlight function to my phone? I miss having that feature as I've had it on the last 3 phones I've owned.

The post above yours should do the trick. If you're talking about a toggle from the notification bar, I think it is built in most custom ROMs.
