[Q] Phone screen not turning on after screen timeout - LG Optimus 2x

Hello, I'm currently using the P.A.C Man 22.1.0 ROM and sometimes when I leave the screen to timeout on itself, turning the screen back on using the power button wouldn't work. Most times I have to remove the battery to get the phone going again, but when I do, I see that the battery percentage often drops 10-20% of what it was before. Is there a reason why this is happening and is there a fix?

it is a bug .. so flash it again or try new rom . hi thanks i i helped

Button lights still on after power off

Hi all,
I have run into an odd problem. When I completely turn off my phone, the light behind the bottom 4 buttons stays on.
I have only had the phone for a week and I think it has only started happening in the last day or so.
The phone isn't rooted. Last application I installed was tasker if that helps.
Any ideas??? Thanks in advance.
Cheers,
James

my htc incS happen on this problem too..could some1 help me..plz...
Turn off fastboot in power settings & switch off & see if lights remain on. Try pulling the battery out , wait for ten sec & then insert, close back cover & then power down (with fastboot off). I think then your phone will shutdown OK. Had an Asus P 565 with a similar problem two years back, was traced to water ingestion during service.

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

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.!

[Q] Flickering Dispaly

Hey guys
I did get a very serious thing with my phone. The screen started flickering today, and I have tried almost everything I could find on the internet.
Have wiped all the settings and so on. What I havn't done yet is flashed stock kernel.
Have any of you experience that thing and what did you do?
I had the same. But random. On stock. Pressing the power button to lock and then waking the phone worked. Untill the next time it happened.
