yeah just like Cedlad mentioned its caused by an app and its not harmful to your phone but it is very annoying.
Just uninstall one app at a time (from newest to oldest) to find what app is doing that.

So its not some hardware problem on the powerbutton or smth like that?????

My OB scares me at night cuz its screen turns on for absolutely no reason, and the worst, it has an app to turn the screen on only when detect movements, like, dafuq, ghosts want to play with my phone

[Q] [HELP!] Power Button is Not Locking Screen

This just happened yesterday after I used the camera and went through the gallery for a little bit. My power button doesn't lock/turn off the screen anymore, unless the lock screen is the one displayed. It still does all of its other functions properly - just doesn't lock and turn off the screen when I press it if I'm in an app or on the home screen. Anyone have any idea what happened and how it can be fixed??
It's a pain right now to have to wait for the screen to automatically turn off, so any help at all would be greatly appreciated!
I don't have any suggestions for a fix, but if you can't figure anything out, there's a workaround. Get one of the widgets from the market that locks your screen... not the best solution but better than nothing.

I ended up resorting to flashing a ROM all over again.
If you have Spare Parts installed, its the reason... Go to Spare Parts/End button behavior and change it to "go to sleep"... i had the same issue today
And why is this in development?

Yeah, I've experienced the same thing also, few times.
I think this happen when you have notification.
Waiting for firmware update.

For me this is compleatley random, once per 20-50 off's.
No notifications, no difference whether i switched off thru button or thru widget (i use "Screen Off").
So if some one have an idea how to stop this, please help
Maybe you have a faulty unit?
Are you rooted??

I hardly belive it is fault of my unit.
I spoted it with original firmware and now ater unlock, root and revolution 2.2 (basicaly same firmware with modifications i like )
Actually i think Sony's devices get that issue. And that is because of the app is not compatible with the rom.
My solution: turn off the lock screen!

Same issue here too, I believe it is Sony's problem, hope a new update will solve it..... turn off lock screen works but hate to use this way.....

I don't think is the low battery mode, I don't have it turn on and it still have the problem, I think it is when the phone get some notifications or go to internet for data then the phone with get activated but it does not go back to total sleep mode.....
low battery mode for me. I've got it set at 15% and when it charged back to that amount the backlight turns on.
Just a glitch for me and a waiting firmware update.

Power button not working??

My phone started to act really strange today. When i press power/lock button it wont lock it turns off phone immediately. Sometime it just gives powers screen (wher you can turn off,restart or go in airplane mode). Butt its really strange. I can turn off my phone only if i unplug battery.
So the problem is that when i press power/lock button it will restart or wont happend anything.
Im long on this ROM and its not problem with it. I tryed go on stock ROM and same thing happends.
Anyone have some suggestion ?

Try 2 hold 8 seconds on power button, if this phone will reboot - it's software problem. Just flash a new firmware LT6 for ur phone.
If it does not work, try 2 disassemble ur phone, and watch area nearly power button. If it's damaged go 2 service.
My opinion plastic nearly power button area is damaged, or this is firmware trouble in UI.
Nothing happend after 8 sec's

[Q] Lock Phone - Can't Use Buttons & Wake It Up Again

So for some reason, randomly, I will lock my phone and not be able to unlock it or get the screen to come back on.
So I will lock my phone - come back - screen will be off - can't press any keys (home, power, volume) and get a response. Notifications and stuff still happens. I have to hold the power button in which the screen flashes (a line shoots across the screen, disappears and then Galaxy Note 3 shows up).
any recomendations?
That's not even close to right. I would be taking it back to where I bought it.

This must be a software issue. I've had this happen to me as well. Only once in the last two weeks. Seemed to happen when locking and unlocking repetitively.

Yeah, sometimes it wont happen for a long time. Sometimes it will happen repeatedly.
I dont know if related, by Knox keeps saying something about software trying to access information every time I reboot. I have no idea WHAT app its talking about because it doesnt freakin tell me.
Happened once and can assure you its a software issue. If it continues to be a problem I would recommend a factory reset.

ah okay.. in my case i wanted to turn it on (from stand-by) and it didn't react. or actually the screen was very low-lighted black. after i push the 2nd time the power button the screen is completely black and the 3rd time i press it it works fine. not that bad but sometimes really annoying
Same case with me many times and thats annoying
Sent from my C5302 using xda app-developers app
yes, but i'd like to know, where exactly this problem comes from? if it is a problem in the system couldn't there be developed any tweak or similar?
It is a bug in the software. It does wakeup the phone and i am able to enter my patern to unlock it but i cant see it. After i turn my screen off and back on again it works normal. This happens only after a very very long time of deepsleep. However my screen turns on when my alarm goes off at 7:30 am
so far I can confirm this is a bug on sony's stock rom, as I have tried MIUI & CM 10.1, and right now using CM 10.2, the problem doesn't arise. the screen unlocks perfectly normal.

yes that bug is still there, although it isn't that frequent so not a major problem, it can be annoying ...
goes away if hit the power button again to turn the screen off and again to turn it on to the lock screen.
hopefully it'll be fixed in the next update.
regards
True that!... I do face this some times.. the screen lights up but its black...
need to press the power button again so that it gets locked and wake it back to normal pressing the power button again...its annoying.!
