[SOLVED] Weird screen off/lock screen bug? - LG Optimus 4X HD

My missus' 4x has the latest cm10.1 release and werewolf kernel installed.
When she presses the power button to lock the screen it goes off, then weirdly lights back up on the lock screen until it times out to black again.
Anyone know how to stop this weird extra lighting up glitch?

Sounds like a wakelock issue - might be worth checking a logcat.

Not wakelock.
Issue 1: CRT Animation is derped, go to settings>Display>CRT Animation OFF.
Issue 2: Dodgy Hardware and Lock button is registered as a double press (Unlikely)
Isuue 3: Just Bad Rom in general, a video wouldve been nice thou tbh, bad explination.
Issue 4: In security have power button instantly locking the screen.
Soloution, install XPOSED FRAMEWORK, install XBLAST TOOLS, play with the settings a bit idc, find CRT animation and select remove alltogether.

I've just changed the animation, so I'll see how that goes first! Thanks!

Ok option 1 didn't work! I'll try option 4 and xposed later today

I noticed the same problem today after i flashed OP 2.7.. I turn the screen off, the CRT animation shows but after that, for about a second, there is like a dimmed light on the screen and then it dissapears.. I am on Carbon 4.3. and I didnt have that issue on its stock kernel. I tryed shutting CRT animation off and in settings set "non delay" but it didnt help..

This happens to me on every ROM I try. Stock and CM.

Solved! It's an app that requires root permission but has not yet been given it! In my case it was terminal emulator! Opened it. Typed su and enter to force it to ask for root permission and gave it. No problem since!

[Q] Lock screen/waking phone delay

Last night, I decided to check out some of the new roms out for the droid 4 so I downloaded the avatar rom and tried it out. It worked fine except when I would lock my phone and put it into sleep mode, it wouldn't always wake up the screen when pressing the power button. The lights for the hard keys lit up, but not the screen. Then sometimes the screen would light up, but the touch screen wouldn't be active so I couldn't swipe to unlock. It usually takes between 5-10 tries until it finally works. I had the same problem with the AOKP rom as well.
I thought it might be the performance controls keeping the CPU too low when the screen was off and therefore having trouble waking it up so I set the minimum to 600 but that didn't help. Any ideas?
Also, slightly unrelated question but is there a way to turn off the transition animations for 4.2.2? I can't seem to find it :/

I have had similar issues with the 4.2.2 ROMs although not as often as you. It would happen to me maybe once a week. I would just hard reboot the phone when it happened. Not sure if it's an issue with the kexec kernel or what.
As for the transition animations I would assume they would be in the launcher settings somewhere.

[Q] Screen off app

Hi there,
im just searching for a simple app, that i can launch, which will turn off the screen, nothing more. Ok, now you say search the play store and you are right, there are plenty of them.
BUT all of them have the same problem: The screen goes off first, then back on and finally shows the lockscreen. But im just look for off, nothing more. Does anyone know an app which does work correctly?
Thanks!

not sure if it is what you are searching, but try an app called Gravity Screen-Off, I use it and I've almost forgotten that the One has a power button on top

I am using turn off the screen app without issues. I like it because you can change the shortcut label and has really polished look to the icon.

I have also used the lock screen widget, but it takes up more memory and the icon is not as nice:

Thanks for the input. Gravity screen off hast the same problem unfortunately. Turns the screen off, it flips back on and i see the standard sense lockscreen.
@crushalot: I tried "turn off the screen" already, same behaviour as mentioned in my first post. Are you on a viper ROM? Im using InsertCoin...

Yes, I'm on ViperOne. (Not ViperRom, confusing isn't it!)
I have seen the issue you describe in the OT but I can't recall having that issue in months. Not sure what it has to do with, could be a conflicting setting/config in the rom.
Try searching on that symptom to try and track down what causes it.
ViperOne allows you to set the volume down button to lock which is nice. Also a custom kernel like ElementalX will allow you to use the htc logo to lock/wake.

If you're into using pie launchers you can use key 26 in lmt to turn off the screen.

Unless you disable the lockscreen or delay the actual time after the screen turns off to lock, you WILL see the lockscreen after turning off your screen.

What do you mean by this? I have not disabled the lockscreen (I use the productivity lock screen on every rom I flash) and changed nothing with delays and the app I referenced in my original response works perfectly on every rom I have tried.

From what I gather, the OP wants something to turn the screen off and make it NOT go to the lockscreen but the home screen instead, but I don't believe that's possible to do without disabling the lock screen or using an app that does so?
Although, I take that back. It is possible using Gravity Screen if you enable the "Disable Screen Lock" feature as it allows you to turn off your phone without the power button and doesn't enable your screen lock (unless you said in your settings that you want to activate the screen lock right after the phone goes to sleep). I have mine set to lock on power button and automatically lock a minute after sleep so that way, Gravity Screen does not lock my device. Although, this isn't the solution you were looking for per say.

Not completely right. I just want to press a button/launch an app and my screen goes off and stays off. Nothing more. At the moment it turns back on showing me the lockscreen which i generally want to use, but i dont want to see it in this particular situation . I hope all clarities eliminated ...
On my old One X with Android 4.1.2 everything works fine with those screen off apps...
@ crushalot: I will take a look at custom kernels, maybe they will help .

I honestly have no idea what you're trying to say now. Are you saying that the screen goes off, but comes back on after you turn it off? Or are you saying that when you turn it back on, it shows the lockscreen?

The first part is right . It just comes back on from itself, right after turning off in the first place. I dont press any button, the phone is doing this on its own.
(Launch the screen off app -> screen goes off -> screen turns back on -> shows lockscreen) -> after screen timeout screen off again -> stays off. This is what happens. The first part (in parentheses) happens in about 1 second of time.
Im using InserCoin with Sense and llama for automation.

Try disabling any screen off animations like CRT off.
Do you use any apps like Screebl? They are known to cause this issue.

Hm i have the CRT Animation activated at the moment, because i really like it, but maybe it interferes with the shutdown...ill keep that in mind, going to flash again on sunday^^.
And no screebl or something like this, screen on/off is a manual thing at the moment.

tried all of them and for me the best is the one called Turn Off Screen from marinelli.tv, you can find it on ggogle play. Work perfect for me on Android 4.3 sense 5.5. Maximus HD 21 rom.

Lock lag?

As the title says. When I lock the screen using the power button I get about a 1.5 second lag between when thr button is pressed and the screen goes off. This doesn't happen every time. Any ideas? Also my transitions to .5 keeps resetting itself back to 1! So frustrating
I experience exactly the same lagging while locking the phone. A fix to this solution would be much appreciated! Thank you...
I have the same issues, even when all the fancy settings (watercolor and sounds) are turned off it still lags.

I had that issue as well for a little bit, but it seems to have went away by itself for me.
I had some of the same issues but I noticed when i rooted and did a full wipe of the phone a lot of these small issues went away. One that bothered me was screen rotate. It would take about 2-3 sec to switch.

Same issue here. Although there was at least one instance that i locked the device and it made the lock sound play, but the screen remained on for well over 5-10 seconds. Weird. Might be related to the new packet mode thing this phone has where it uses little power to deliver messages while the screen is off. I forgot the name of it.
I have figured out that if you disable multiple widget lockscreen it makes it turn on/off faster.
I am now experiencing this! When I was rooted on m1 I never had this problem but now that I'm on mj5 rooted it lags horribly on the lockscreen..... But not all the time only every once in a while! Has anyone figured out a fix? I'm contemplating a factory reset!

Anyone have screen flickering issues with their HD?

My HD (running 10.1.3 stable) has just started behaving strangely when I wake it up from sleep. The screen will flash then go black. Whether I push the Nook button or the power button, the same thing happens. It may do it 2 or 3 times before it comes on. Started doing this yesterday. Just now, it would not come on at all. I see the screen for a half second, then it goes black. Just wondering if it's already toast or if this is a known problem with a remedy.
Probably software issue.
If your using a magnetic case (problem)
You could try disabling the lockscreen if its enabled.
Daydream could in my theory affect that time frame.
The backlight should last years longer. The gpu should as well. I can't think of any other hardware issue.
If you have an sdcard try cm11 [or the bn rom] and see what happens. OR full backup of current rom in cwm and flash cm11 to internal. Clean and restore 10.1.3 and be back to right where you left off.

Yes I have the same flickering issues when trying to wake it up from sleep. I would have to press either button numerous times to get it to stay on and not black out. I'm on the same 10.1.3 stable. I am using a magnetic case but it happens without it. Before this happen, my slide to unlock screen would act up by not unlocking when I slide to unlock; it would just go back to the initial lock screen. Slide to unlock would not work so I turn off the lockscreen, now experiencing blackout screens when I try to wake it up by pressing either buttons. This problem happens infrequently but it is annoying.

I learned from another post that if it does not awaken when the magnetic case is opened the first time, close and open it again. This works for me 95% of the time. Sometimes there's 2 or 3 second lag but it almost always comes on.

Works like this on my HD+, too. Sometimes requires opening case cover twice, but the screen always comes on.

Screen stays black when i answer calls

hi, i'm having a issue with the proximity sensor. Sometimes when i answer calls, the screen stays black even if i press the lock button, sometimes i can't even answer because i can't turn on the screen. Once it had the problem, if i open an app to test the proxymity sensor it tells me that the screen in always covered. If i reboot the phone everything goes back to normal, until the next time it decides to malfunction. I don't use any screen protector and i had this problem with resurrection remix rom and CM 13 snapshot... Anybody had the same issue? Or knows how to fix it? the thing that is driving me insane is that it does this only sometimes, at random...
There's a fix to this. Go to accessibility settings and tick power button to end call. Then reboot. And then untick it. Itll be solved after it. Had the same in my nexus 6 too.

I had same problem on my phone. I discovered Proximity Sensor Reset through another XDA post which fixed the problem for me. Google Play Store, it is simple and has remained effective through reboots and ROM updates. Maybe it will resolve for you and others too.
