Flickering white pixels in some places? - HTC One X

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

Anyone with a VZW Gnex have screen burn-in? I have 0...

Just wondering because I've seen a few posts already about screen burn-in, but I've had my Nexus since launch and have no problems at all. Is it because the people that are having the issue are using the GSM version and have had it longer? Is it because those people have their screens on all day?
I'm just trying to get a baseline to understand where the problem might be coming from. Don't get me wrong, I'm not in highschool so I have no need to keep the phone screen on 4+ hours a day (I average somewhere around 1:30 a day, but most of that is reading and answering texts/emails)...but just curious.
For anyone with burn-in problems just post which version you have (and when you got it, if you could) and the average screen on-time per day that you have. Maybe this could lead to a "best practice" document to keep it from happening to others!
I am afraid that this might be a redundant post you just made.
There is no physical difference between GSM and CDMA variation's SAMOLED screens. There should be more difference between which factory and/or country it was made than between GSM and CDMA.
I know you have already, but please refer to the posts made on:
http://forum.xda-developers.com/showthread.php?t=1509123&page=2
And I'll re-post the post I made over there on here as well for your information.
----------------------------------------------------------------------------
This will probably happen to all of us to some degree sooner or later.
The image retention that lasts 1-3 seconds we might see within a month or two usage is actually one of the characteristics of AMOLED "Ghosting effect"
which is not the same as AMOLED "reverse led fatigue" (or although technically incorrect but more widely understood term "Burn-ins") which maybe seen as permanent image retention shown as yellowish outlines of icons / keyboard outlines, etc.
Sadly, there's really nothing you can do about this problem after the fact, except to change the screen itself if it is really bothersome. Or you may try to change/delete/make transparent of the permanently placed icons/other objects/pictures to try to reverse these effects.
The only preventive measures would be changing screen rotation from vertical to horizontal, and make sure you don't have the screen on at a stay still image (preferably set auto screen off to 30seconds or so.)

I'm sorry, you misunderstood my point of the post. I realize the hardware is identical (as far as the screen is concerned), I'm more interested in kind of how much screen on-time has a strong chance of creating permanent burn-in. I have a max of around 1:30 of screen on-time per day and I haven't seen a hint of burn-in...so I'm wondering if there's some magic number of on-time that will cause the problem to a much higher degree.
What I'm really hoping for is that, for instance, if we find people with 2:30 of screen on-time seem to really have the issue but people with 2 hours or less don't...then it might be a helpful practice to kind of keep screen time to a minimum above that. I realize it's not really helpful for most people (because nobody wants to curve their usage), but it's a limitation of the hardware.
Or maybe if a majority of the people with the problem seem to keep on the screen for 15-20 minutes at a time...that would help, as well.
Its going to happen. All amoled screens get it. The 2 verizom demo units at the store here have it really bad cause the screen is on all day. If you use transparent top and bottom bar, full screen in browser, and rotate your screen periodically, you can avoid the issue.

Oddly enough none of my previous amoled based devices (captivate, SGSII, Galaxy Note) shows any signs of burn in but GNex shows slight ghosting/slight burn in of the notification bar. It's feintly visible when i open the xda app

Flickering screen

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.

[Q] Appearing and disappearing white pixel?

Hey guys, today I noticed something weird on the left-est (if that's even a word) panel of my HOX. When i click on bottom half of the screen, a white pixel appears and stays there until i touch the screen again and sometimes the white pixel just flashes! This only happens on the 1st panel (from the left) and I don't know if it's just a glitch or a hardware problem. The thing is, this is my second HOX (I had another one for 1 week before replacing it (it had a small black circle-y spot) ) and I had it for more than 2 weeks and the returns policy of the store I bought it from says that they can't replace it if it's more than 2 weeks old. Any ideas if it's hardware or software related, or even ways to check so?
UPDATE:
I think you'd want to know that I have an HT23 model
I had a similar problem with a bright red pixel at the left of the center of the screen. It usually appeared when I am not touching the screen and disappears when I do. After the screen got a yellow tint that appeared next to the volume up button which got worse the hotter the phone got, I took it to the shop and they replaced the "touch, battery and speaker". Touch pretty much means screen as well, I have no idea why they changed the other 2.
It's definitely a hardware problem since I had a similar issue with a stock phone. Btw the yellow tint appeared after 5-6 months, the red pixel was there pretty much from the beginning.

So should I go and ask/demand for a replacement? It doesn't bother me, I don't even use that panel at all, what annoys me is the fact that this is the second HOX I've had and it also has a problem!
It's a hardware fault go and demand for a replacing (HT26+/SH26+).And, if someone later on (in this thread or else ware) suggest to use a software to fix it. Don't bother with it.
I have HT25 with yellow tint showing from time to time. It's annoying me, and still I didn't get the chance to give to to HTC care.

[Q] Getting horizontal lines intermittently

My phone is about 4 weeks old now. Last week I noticed that sometimes, powering the screen on shows some light pink/grey horizontal lines. This is in standard portrait mode.
They are more obvious in medium to bright light and eventually go away after another screen off/on.
I'm using the standard HTC ROM (Sense 5.0, Android 4.2.2).
Would this be a hardware issue?
Thanks!

Sounds like hardware. I knew someone with a Thunderbolt with a similar issue. Next time you see it, don't turn your screen off, but lighly push on the screen in different areas and see if it makes it better (or worse). This may have happened (if its hardware related) due to too much pressure being put on the screen accidentally, perhaps while in your pocket or something.

I did notice the lines again and tried pressing on the screen but nothing changed from what I could tell.
I ended up contacting HTC support and was recommended a 'Dead Pixel' app. Except they didn't specify which one. There's tons on the market and some claim to fix dead pixels. Not sure how true that is or that I even have that problem. Anyone know if those apps work?
Also, they recommended doing a factory reset. Not sure how that would help but I'm willing to give it a shot if there's no other ideas.
I'm not familiar with the apps either, a factory reset would help rule out a software related issue, and is probably the first thing that Verizon would do.

Question Screen dim and flicker while on

This is different than the known issue of screen flickering while off.
Today (3/20/2022) my 6pro screen started flickering, and half the side was almost too dim to read. The odd thing - the top left notification area over to the camera notch was not affected. Given that this one stretch is unaffected, I'm wondering if this is some sort of software bug.
I factory reset the device after the video, and the flickering was more tolerable - ie the entire screen other than the top left notification area would flicker, but it was a much lighter flicker and no longer causing half the screen to go super dim. I tried disabling adaptive brightness, but this did not resolve the issue either.
I'm holding out hope that the March update will fix, but curious to know if anyone else is experiencing this.

this looks like a hardware issue.
To be sure, use the AFT (Google's Flash Tool) and choose wipe and force flash partitions (by hitting the pencil on the flash page). this is the only way you'll know for sure the device is defective (unless it has been dropped etc).

Thank you for the suggestion, but unfortunately the phone has now become completely unusable. I can no longer see the majority of the screen - and can only see a small portion of the top left corner.
After about an hour of chat support with goole fi (and being bounced around between google fi support and google store support) I was finally able to order a replacement device.
I have pixel pass, which includes preferred care - while that was advertised as "Hassle-free phone repairs, replacements, and more." based on my experience of being transferred to 4 different people only to end up in the same dept. that I started at, it is anything but "hassle-free". Hopefully the rest of the process will be easier.

yeah that flickering was not at the OS or display profile level, but deeper.
You didn't drop your device right? So it's a standard warranty claim - and that shouldn't include any out of pocket expenses for you ($29 or $129 exchange fee ect).
Never had preferred care... but if it falls under the regular warranty claims, and you have Preferred Care, can they just send you another device? (without any cost to you)?
I can just imagine now, trying to get any of this information, straight, from Google Support. My head would spin (;
