Flickering white pixels in some places?

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

Screen brightness

My wife and I both have month old gs3's. Both are stock, have brightness set to auto, and power saving mode on. However, hers is much brighter than mine.
She has a white phone and I have a blue one. Am I missing another setting that could be different on our phones?

Have you tried manually going through each of the brightness settings to see if they are different when not set on auto?

Yup. They're the same. It's only with auto.

In my experience auto brightness has never really worked properly for me on any Android I've had.. I personally always have my screen as low as possible, it's pretty bright even like that.

I have heard that its not uncommon for inconsistencies in screen brightness on some phones. May be a quality control issue
Sent from my SPH-D710 using XDA

If the brightness of the phones are working manually then i would just chalk it up to minor inconsistencies in the photo cell's on each device, which is to be expected.

Check if "auto adjust screen tone" is checked in Settings -> Display.
EDIT: If it's only with auto, maybe the brightness sensor is a little wack. You could try the Lux brightness app in the play store, as you can manually set the outdoor brightness/screen brightness ratios.

Sorry for bumping this but I have the exact same issue. Mine is blue, my wife's is white. Her phone is way brighter set to auto than mine. It's the same if auto is turned off, her phone is way brighter.
Google searches don't reveal any suggestions...

So this is definitely not a blue vs. white phone issue. In my office, four other people have Galaxy S3s. Three are blue like mine and one is white. I compared all of their phones to mine and mine is way dimmer and a slightly different color temperature than theirs are. I did a factory reset on my phone and it made no difference. The phone is only 12 days old so I am going to take it back up to Best Buy today and see if they can swap it out.
**Update**
Best Buy swapped the phone for me and the issue is resolved for me. In fact, the new phone is a little brighter than some of the phones I had compared to before.

Can anyone here please confirm whether this used G3 is in good condition?

So I've just got this used G3 for about half the retail price with half a year warranty time remaining.
Specs: 16GB Storage, 2GB RAM, OS upped to Android 5.0 Lolipop
After spending some time playing around with the unit without a sim card, I came across some less fun facts about this G3 which are as following:
1. The unit gets warm/hot pretty easily under normal use, an app called CPUZ detects that some temps would go up to 70*celcius.
2. Battery drains a bit to fast under normal use.
3. Sometimes brightness can't be set past 90 with a warning message saying something like "brightness can't go 100% due to high temp" pops out.
4. Camera would sometimes crash and render unusable before the system is restarted.
5. It's either I didn't know how to properly use the camera (but I believe I did cause I used it the way people demonstrate it over the internet) or the autofocus no longer works the way it should as it always fails to freeze moving objects during a capture. Not to mention grainy in low light.
6. When brightness is set to Auto, the screen would turn way to dim. It seems as though it's nothing like an ambient light sensor because the brightness won't turn brighter nor dimmer in any light situations.
7. There are some seemingly minor scratches on the laser and the camera, I would like to know if they affect some performance.
That's it for now, everything else seems to be in great condition. Do you guys think I should use the remaining official warranty time to RMA it while still can?
Thank you for reading!

If you haven't done a factory reset yet, I suggest you do so. If nothing changes, no doubt your phone has major issues, RMA.

I have done a couple of times of factory resets and nothing changed I'm afraid
Anyway I would like some detail on the major issues my unit has so I might be able to detect if certain defects still present on the replacement unit.
Thank you!

Brought my G3 to LG Cust Service and the LG guy said that the high temp is normal(my G3's idle temp is around 55-60 Celsius even after factory reset) and today I just got contacted by the LG guy again telling me that he already reviewed my G3 by comparing it with another G3 of same model at his office, he told me that G3 are that hot, he wanted me to come and see for myself.
Could it be because the other G3 he uses to compare my G3 with was of the same bad batch? because many reviews of G3 on the net seem to be very positive and there are barely any mentioning about high temp

Android P what have they done with the brightness?

Just installed P and now previous brightness level of 63 it's so dim? I have to have it almost on 90% brightness now, why have they messed with this, it was fine as it was

Same for me. WTF Google?

The actual brightness is the same, they just changed how the slider works. The first half moved it fast, last half moved it slower. Now the slider is more uniform.

It's definitely not smooth across the entire range, all my brightness is almost all the last 10% and actually a pain to set properly, it's worse for me.

That's more accurate because in bright indoor lighting or outside it's going to be towards the end of the scale. Dim indoor lighting I'm currently at 43%. And in pitch black it goes to 0%. I pretty much never touch my slider anymore after a couple adjustments. Don't get caught up on the percentages. I would be willing to bet that with Oreo at 40% and Pie at 90% the lumens output of the screen was the same.

Yeah I don't touch mine once it is setup generally but it's definitely not even throughout the scale, only gets really bright from like 85% onwards, just seems odd the real brightness is so high up, makes for fine tuning a bit difficult.

The screen has been rated a minimum of 1.78 nits and a maximum of 496 so if it truly is linear now, 50% is something like only 247 which isn't that bright at all.

Hi
So much for AI on adaptive brightness, it's rubbish, and why do Google try to fix things that aren't broken, who needs AI for adjusting a backlight? Seems nothing more than just being able to market the phone as having AI! Never had an issue on Oreo, had it set at 25% with adaptive brightness and it was always the correct brightness wherever I was, which shouldn't be difficult given it's got a sensor to read the light levels.
Now since Pie, last night I turned my phone on in the dark and was blinded by a bright display (Oreo it would have been at it's lowest level in the dark), so turned the brightness down, turned it again later and the same thing, way too bright, and again this morning in a fairly dark room the same thing, far too bright, so I turn it down again. How long will it take to learn? The old method it was tamed immediately, now I'm constantly fiddling with the brightness, how is that progress!
Is there an option to go back to the old method?
Wish I hadn't bothered upgrading, just another year with an Android update with changes for changes sake.
Regards
Phil

Totally agree on this. Adaptive battery and adaptive battery are almost non-sense. Only something cool to brand the item.
And Pixel Visual Core is just something super-expensive to make Whatsapp, Facebook and Twitter cameras use HDR+. I'd rather pay something less and not having this feature that is probably expensive (or modifies the perception of the Pixel 2 as super-new and mega futuristic). Also, I've got the feeling they won't use it for Pixel 3 or 4.
Moto X1 was the last to use more CPUs to optimize the phone, before Qualcomm introduced more chips.

Hi
For any one having this issue please report this from your device at Settings > System > About Phone, the more people that flag it the more likely it will get fixed.
For me, I hate these updates that break simple basic functionality and overall add nothing extra to what we had with Oreo. Google really need to test these things properly and stop trying to fix things that simply are not broken!

Phil

Already reported, i shouldn't have to have my phone on 90% to be the same as what it was on 63%

Dark Marks and Color Bleeding Along Edges in Low Screen Brightness

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.
