[Q] Screen goes off after unlocking phone - T-Mobile LG G2x

Has anyone else had issues with waking up the phone?
Every so often when I hit the power button to wake the phone, the screen turns on but looks super glitchy for a second or so, then shows the normal unlock screen.
When I unlock the phone, it instantly turns the screen black. The phone is still "on" as I can push icons, etc. If i push home the phone still vibrates but the screen will not "re-awake" unless I push the power off and on again. This has been happening quite a bit and is annoying to say the least. I also seem to be having in phone calls with the light sensor as the screen goes black just as I am about to push push buttons while I am in a call.
Is this just me or are others affected by this. I didn't see this issue discussed within all the other reboot/glitches threads.....

Mine is a little lagy when unlocking and occasionally I get a weird squiggly looking screen for a moment, then it is fine.
I assumed it was because I have a SetCPU profile set to 216 with a priority of 100 when the screen is off.

Mine when I unlock it it stays on the lock screen. The phone is still "unlocked", but it shows the lock screen and it doesn't change no matter how many times I lock and unlock. It is very annoying. I got it on CM7, Bionix, and the GB leak. I went back to stock 2.2.2 just because of this reason. Anyone know what it could be?

lock screen issue on all roms

ok i can reproduce this on multiple roms on multiple phones,
symptoms: when you press the unlock button on your screen it flashes whatever you had on your screen prior to you locking it
how to reproduce
step 1: open up any app
2: lock the screen with the physical button
3 unlock the screen with the same button and it will flash the last thing you had open prior to locking it, then show the actual lock screen
4 without unlocking the screen, turn the screen off by pressing the lock button
5 unlock it again, this time because the last thing that was on the screen was the lock screen itself, it wont flash the apps screen, and the lock screen actually performs faster due to this.
ok, so here is my point, if there was a script the told the system to display the lock screen before turning the screen off and lock it, the wake up time would be significantly decreased. any thoughts or input?
what roms have you seen this on?
im on mosaic and cannot reproduce that. its the lockscreen as soon as i press the button.
on the captivate, stock, cm7, serendipidy, and andromeda,
on htc inspire, stock and rcmix3d, cm7
and it does it on nook color running cm7
Yeah, my stock rooted 2.2 does this.

cant reproduce it on Serendipity 7, I am using the SGSII lockscreen
seems like it comes and goes. does it some times, usually when laggier, but sometimes doesnt...not all the time though...
That's just the last image left in the static screen memory. It would probably take more time to clear the memory than to leave it there. It doesn't happen for me but I have the CRT anim installed, so it blanks it out before shutting off.
doesn't happen
on Nostalgia 1.5 with Glass unlock

[Q] Lock Screen cut off and off center

I've been running into an odd glitch with the lock screen every now and then. The visuals on the lockscreen are shifted up halfway, and the bottom half is black.
If that doesn't make sense(ha ha, pun), the ring pull is in the center of the screen, and the top half is pushed off the screen.
The touch spots for the icons and ring are still at the bottom, however. So I need to press in the blackness below and slide from there. Everything animates properly, but it's rather clearly not right. Plus, anything I have set to display on the screen (weather, clock, etc) isn't visible and so kinda useless. Changing lockscreen types doesn't seem to clear it, I have to do a restart.
Anyone else run into this before? I'm willing to bet a factory reset cleans this up, but I'd like to leave that as a last ditch effort.
I would suggest resetting the device back to factory. At least all of your apps would re-sync to the phone.

I was changing ringtones today and the display went off because I stopped for a second. I went to turn it back on and the lock screen had the lock at mid screen and wouldn't unlock. Had to pull the battery.

Even tho the ring appears in the middle, you can unlock it just like its at the bottom and it will unlock. Mine has done simular where there bottom half is just black.
Yes this happens to me too sometimes. not often though. Once i restart the phone it goes back to normal. not a big issue for me.

[Q] screen wierds out

I've had an odd problem with my 820 almost since getting. I'm hoping one of you geniuses have some advice.
When I turn it on it works perfectly, sometimes for hours. Then the screen goes blank, and then random pixels begin to appear, starting at the top of the screen. Outdoors rather than random pixels the screen goes almost totally green. Strangely, if part of the screen is obscured the green only covers rhe exposed area.
Pressing the on button repeatedly usually brings back the lock screen and reset (on+down) fixes the problem for another few hours.
By the way, eventhough I can't see the screen the touch sensor works. For instance I can hold theon button and then swipe downwards to turn off the phone. I can also answer and hang up using earphones.
My daughter who purchased the phone said it worked fine until the amber update. I had hoped the black update would fix the problem but no change. I found some posts from people with the same problem who sent the phone in to be fixed and got it back in the same condition. I really don't want to go through the hassle unless I expect to get it back fixed. I'd rather try fixing it myself.
My question is whether this is a firmware problem an whether it is likely that re-installing the stock black rom would do any more than the ota install that occurred automatically did (or didn't do).
Any ideas?
Nobody?
By the way it seems to happen only, or mostly when in standby.
I installed an app that displays a clock and doesn't allow the phone to go into standby mode,
and the problem doesn't appear to occur (unless I forget to leave the app on top).
I would set the phone to standby = "never" but the option isn't available on my phone, though
I understand that there are those with the standby = "never" option.
Any idea if I can set standby = "never" with keyboard commands, perhaps?

[Q] Screen is blank but phone is working

The screen of my OPO went blank, but I believe the phone is still working as it gets notifications, the torch comes on with the "V" from the standby screen, phone wakes from a double tap and the phone rings when called from another phone. But the screen is completely blank, so I cannot reset it because I do not know where to touch the screen.
I have entered a repair ticket with OPO support but they are advertising a wait of at least ten days before any response and I have tried, but cannot hold my breath quite that long. Any help would be greatly appreciated.
Same problem over here, have been using phone for few months without any problems, very carefull with my phone, no drops, moist or whatever, but suddenly this strange blank screen starts to occu. Backlight buttons come on and vibrate but screen stays blank.
I can however reboot my phone by holding the power button until it vibrates, phone will work ok ..... until it happens again.
Try clean flashing whatever ROM you're on and go from there
I think it's referred to as "SOD" which stands for "screen of death" maybe? Or darkness? Lol I dunno search for sod

Screen is constantly locking for no reason, is my light sensor busted?

Hi all,
When I'm using my month old Nexus 5 it will just randomly kick me back to the lock screen, sometimes I can just unlock it and keep on trucking but sometimes it will just immediately lock again or it will work for a couple of seconds and then re-lock. Once its in this state even a reboot doesn't always help and about the only thing I can do is get into recovery mode and re-flash it again. I used the Sensor Box app and have noticed that the light sensor is always reading zero, and I'm not sure if this is part of the issue?
This was happening on the PA Alpha, Stock 5.0.1 and since I was still having the issue I flashed back to 4.4.
The weird thing is that my phone had been fine for the 3 weeks or so I had it before hand. I flashed lollipop on it less than an hour after I took it out of the box and it had been running smoothly up until yesterday.
So a few questions:
Is there anything I can try to fix ir?
Can I use debugging to see what is causing the screen to lock?
Is this likely to be a hardware issue?
If it is, is there anything I will need to do to make sure I keep my warranty?
Any help is very much appreciated.
Bump with some other information:
I don't think its the light sensor, I tried using the phone in a pitch black room last night and the same thing was constantly happening, there was something else odd happening though.
From the restore of 4.4 I was on the "Select language" screen, whilst I could swipe and roll the various language options up and down the moment I presses "Next" the phone locked, if I left the phone on this screen eventually the screen would automatically lock and then it would keep locking itself constantly again.
Also, just for total clarification by "lock" I meaning "return to lock screen" not freeze up and become unresponsive.
