Recently, my screen starts to have some narrow trapezoid dark marks along the left and right sides when the screen brightness drops below 40% (like 28% set by Auto Brightness). Sometimes there is also some color bleeding (from the icons and background below) at the top edge when the dark marks appear. When the brightness is 40% or above, they disappear. I suspect it has something to do with the PWM that controls the brightness. Does anyone has similar experience and any suggested ways to fix it? I am considering to send it to LG warranty repair. Thanks.
It's unrooted and on stock ROM, right ?
you could try a factory reset and see if it changes anything ...
Was the phone particularly hot at the point in time ?
Are you gaming ... like a lot ?

It is a T-Mobile, so no root and stock rom.
I may try a factory reset and see how it goes.
No, it was not very hot when it happened. It was at normal operating temperature.
No gaming. I don't even have any games installed. Those are not burn-in, as they are not in a fixed position. If I adjust the brightness, the dark marks will shift their location with the brightness %, so I suspect it is the PWM that causes it.

Could very well be, I'm however also thinking about SoC and Die (https://en.wikipedia.org/wiki/Die_(integrated_circuit)) issues [hardware defect]

I agree with you. I did a factory reset and the issue remains, so it is likely hardware failure. I sent it to LG Warranty repair and see what they say.
LG diagnostic finding is "Display screen is discolored", so it appears to be the OLED screen that is defective and is covered by warranty. The "LCD (Main,Sub)" is replaced. I didn't know there is a "sub" LCD.
I received my phone back, and it seems I get a new phone. It is wrapped in plastic film. Thumbs up for LG warranty.

the back light of my phone started flickering the other day and now ti's set to dim, i cant increase the brightness i have tried different roms and still nothing, it has to be a hardware fault is there a chance its a loose cable or will i have to get a new screen?
also the phone seems to run a bit slower the last few days, i dont know if its my imagination because the screen is going but could this be the start of the end for my phone?

Well....I can guess that its either from moisture or a physical damage. At this point why not try opening it up and seeing if the ribbon came loose....though I doubt that is your issue.
Are you under any sort of warranty? If not then open her up and explore.
I have noticed that my screen is flickering ever so slightly in all applications. it is bearable but slightly annoying. Could this be hardware related and will I have grounds for a warrenty replacement? should I wait and see if any OTAs resolve it?
Everything is stock. Brightness is set to auto.
I have problems with shadowgun crashing when there is an explosion etc. possibly related?

Yeah, i noticed this too on my One X I've mostly seen it while my mobile data connection was on, and it seems to decrease a lot but not completely disappear when it's off. I also got a weird message yesterday while charging, saying something along the lines of "your phone is using too much current, -" (the message was in dutch, not sure what the exact message is in english) my phone turned off before I could completely read it. I wonder if those issues are somehow related. Maybe the screens backlight isn't getting enough power when the radio is on. Anyways, I'm not an expert, so don't quote me on that.
I also heard the tegra 3 drivers are buggy, so shadowgun crashing and performance drops etc. will hopefully be resolved in future updates.
I've got it as well I think it's a driver issue the last thing I want to do is go for a replacement and that to have more dud stuff as this is the only dud thing on mine. Everything else is fine apart from flickers now and then.

@backstabz0r for screen flickering pls refer to my earlier ans and for your problem which you got warning message thats common warning you get when you have put phone in charge and if you using it for gaming which consumpts more nergy then, message will be" battery consumption is more then the supply"
so suggest ou to let battery get charged till 30 % and then use it for gaming or any other apps
I've read a few threads here regarding the flicker and it seems some people are confusing flicker with something that I really don't know what to call.
Flicker for me is when there's a stroboscope-ish effect, like when you place your sight just above an old CRT monitor, or when a fluorescent light is on it's last breath. Not when what you see on the screen makes random movements a few pixels in any direction.
I have flicker on my HOX. But it's only noticeable on lower brightness levels. This happens in all applications and in settings menu, everything with white or light grey background, so not related to badly written apps. But I wonder if this really CAN be software related? Has this happened with other models from various manufacturers?

I've got what your describing quite a few users have. I believe it could be down to the drivers for the Soc. Might just need a driver update. Only the next update we can tell if this fixes the issue or not. We need to pressure HTC regarding this issue.

But is it really possible that a driver issue can cause flicker? I've never seen it before.
I tweeted @htcdev earlier today about it but no response yet. I wonder what the best way to make htc aware of this is. Contacting their lousy customer support feels pointless, it won't reach the people who actually can make an impact.

This is what I have, but its far worse on higher brightness levels.

Right guys untick animations in Developer options, restart give it a while, go into camera you'll notice glitches, play a YouTube video you'll notice green bar on the left hand side of the screen in full screen mode. Untick animations and this disappears. It's worrying not sure what to do now.
Edit: can't repeat this but will keep trying as something did trigger it off for the screen to go like that.
Yeah, with flicker I didn't mean anything like having low fps when scrolling through stuff. I meant a quite noticable fluctuation in the brightness of the backlight if that makes sense. It is indeed quite like a CRT monitor with a low refresh rate. I haven't seen it yet when my screen brightness was high, but I'm not sure if it doesn't occur on higher brightness settings. It is also not constantly flickering, It only seems to act up when my mobile data connection is active, although I have seen a very slight flickering with data turned off. I really hope this isn't a hardware issue, the rest of my phone is pretty much perfect and I'd rather not send it in for a replacement after all the trouble I had with my sensation :/
I have the flicker issue, the screen flickers near the center a little bit to the right though, and it is reall irratating, but i can only see it when viewing pictures and on greys.
I hope it isn't hardware!!
tried all the ideas given to stop it but none work for me, still seems to flicker
Me too
I have the screen flickering too.
Im reluctant to return it as apart from this the handset is solid.
It on appears on certain colours making me think its software related.
I also have the exact same flicking issue. From what I have heard it is a software issue rather than a hardware issue. Just to be on the safeside though I am returning my One X to Phones4U for a replacement. Will be interesting to see if the replacement has the same issue.
I made a thorough check yesterday. I downloaded a brightness control app where you can write what brightness level you want so i tried from 3% which was the lowest possible step by step up to 15%. At 15 the flicker stops so its not 30 as I said before. this is my only issue too so I dont dare to replace it just to get a worse phone. My sister is getting one next week so gonna compare them.

I noticed this too, but i believe its a software issue only. When I unlock the phone, the screen flickers while sense runs and the three menu button appears then goes. Once its all settled its fine. I believe this is to do with sense rather than a phone issue, and will be addressed via OTA.

Not so sure about it being a specific Sense issue as I have noticed the screen flicking in 3rd party apps such as Spotify.

I phoned dialaphone there, i made them aware of the problem with my phone, told them if it wasnt fixed with the update then I would like to replace my phone, told me I had until next tuesday to see if its fixed, until I reminded her about distance selling regulations which gives me 28 days from receiving the handset.

You do indeed have 28 days to return your phone however I wouldn't count on HTC releasing an update before then
Just received my second One X from amazon UK (first was sent back due to charging issues).
Been getting some weird things with the screen on this one, which I haven't heard of in the other threads. I have a fair amount of pixels on the screen that will flicker white on certain screens, particularly on the pull-down notification. The pixels seem to be roughly distributed along two vertical lines on the screen, and there's about 20-30, although it's hard to tell since they never flicker all at once. The white pixels don't show up in screenshots, so I don't think it's a software issue, although it's possible, I suppose.
They never show up on solid colors as far as i can make out, but i get them on the camera preview and in the notification drawer (seems to be that shade of grey combined with the fine texture that sets it off). Very occasionally I get it on the bubbles live wallpaper. I also get it when viewing screenshots of the notification pulldown, so it seems to be the colour/texture, not the actual window being drawn.
I can't tell if this is a software or hardware issue.. I've done a few reboots and a factory reset, which did absolutely nothing. It's always the same pixels, which suggests hardware to me, but then it's oddly specific circumstances that set it off.
Any ideas/anyone else getting similar issues?
Edit: re-reading your post it may not be what I thought. Info below for the "usual" screen flicker issue.
It's a well known issue that pretty much everyone has. The backlight flickers slightly due to a voltage drain when the CPU is busy, causing whites and greys to turn a slightly warmer "colour" for a moment.
It's fixed in the 1.29.11 (not 1.29.7) update which just rolled out in Europe and should follow in the UK in about 2 weeks. It takes up to 2 more weeks after the update for it to monitor the voltage of your individual screen and learn to compensate so the flicker goes away.
Yeah, it's not the backlight, it's literally single pixels flickering from their correct colour to white.
So I've been through the standard factory reset crap with customer service, and they're recommending I sent it in for repair. Has anyone had any luck with the repair centre (I'm in the UK)?
Not sure if it's even worth sending it back since I'm still not sure if it's a hardware or software issue. If it's a software issue, will they fix it, or will they just turn it back and go "nope, couldn't find anything"?
I have EXACTLY the same issue, but with two pixels only, I'm almost convinced it's a hardware fault because I'm on a custom rom and it's still there, I got mine without a warranty though so I'll have to deal with it, any suggestions other than acceptance?
I have same issue, i change the rom and now its fine. it was almost on 3 or 4 roms, and finally its disappear

Well thank you that's rather comforting to know, fingers crossed
Hi,
EDIT
Resolved it (kinda), I shut the "Economy mode" and the screen stop the flickering....
---
I'm creating a new thread for this problem got an answer there telling me it's my phone, but I would like to know if somebody else notice this.
It's like on good old CRT. Got a Note I (got stolen) bought a Note 2 and I can see a flickering, like if the display had a 60Hz refresh rate, never notice such a thing with the Note I.
It's more noticeable on white screens. And when you are using peripheral vision, by pointing your eyes like 10 centimeters from the side of the device, the flickering must be more visible
The effect looks like this http://www.youtube.com/watch?v=M3jHOwE8MqA not mine but can give an idea of the problem.
Thanks

Never notice it with my Note I, it seems that it's partly due to AMOLED technology, but as I did not notice it on my Note I...
Maybe it varies form device to device...

Ok, so if you do not own this device the Note 2, and do not want the device, why chime in and post/comments...
My scraan is flickering too. Feels like old CRT TV. When brightness not at 100% level I can observe this problem. Looks like samsung using PWM to control brightness. I think this is terrible. And I hope this can be fixed by software (adjust brightness by gamma correction etc)
mine also sometimes flickering on the lock screen in the near clock area for about 0,5-1 sec. but no need to worry, i guess its a hidden samsung note 2 feature...
So there are no solutions to fix screen flickering? Maybe we can overclock screen somehow? Maybe alternative brightness control?
The screen flicker mus be due to a bad batch of screens. Mine had the screen flickering too. and even with economy mode shut down and brightness is set to less then 100%. if you rapidly move the phone you can see that you see several screens instead of a blurry moving screen. this way you know it flickers. so for example if you move your phone up and down very rapidly instead of seeing a blurry view of the screen you will see several edges of the screen simultaniously. this tells you its flickering. While just looking at the screen you wont actually see the flickering but its somehow disturbing.
The way i know that your screen is defect is because due to a rescent replacement of my screen on my note 2 the flickering is totally gone now.
But keep in mind that my battery usages with screen on has increased. so i think samsung changed the power management for these new screens so that they wont flicker anymore. but they consume more power now. first i used the screen 6,5 hours and had a standby of 24 hours. now i have 6 hours screen on time with 24 hours standby. so its a bit of a change though. I just tested it 1 time. so it could also be i used the phone in another way when getting only 6 hours.
But just to let you guys know the flickering can be fixed.
Hi,
is anyone having heating issues with display panel ?
I'm attaching a picture of the portion where the heat arise after use for a while.
location marked on picture.
always on 120hz refresh rate
I'm using galaxy s20 5G SM-G981U1
So it's hot there?
Maybe a display or component failure in progress.
Never seen that with a OLED screen.
If an internal component is getting hot enough to effect the display it will eventually cause it to fail.
Return for repair or better replacement.

Maybe a power hungry flat pack under there and nothing abnormal about the temperature difference.
The display on the other hand doesn't look normal... that sucks.
