I have posted this in SGS4 Q&A, Help & Troubleshooting but it's getting no responses there.
Most threads seem to be by potential buyers asking questions about the phone, while issues have topics here.
If this is not the right place, or the other topic is misplaced, please delete/merge either.
So, several people have reported this issue.
While booting, the black is actual BLACK. While charging, the black [not the green/grey battery] is actually BLACK.
When you reach the Samsung animation in the booting process, the areas of the screen previously black get a reddish tint.
On closer inspection, all red subpixels are on, at low intensity. As far as I can see brightness setting does not affect this phenomenon, nor does Display Mode.
i9505 On XXUAMDF:
Comparison, white image, lowest brightness:
Can people report their firmware and model and whether they have this issue? It's mostly visible in pitch black rooms, but you can tell the blackness isn't OLED-black in normal situations. It's obviously a big issue as it will also drain additional power compared to pixels that are off.
I have exactly the same issue, MDF firmware
You can send back to Samsung to get another one, it's faulty
Samsung chat (NL) tells me I should return to the reseller. I'm sure they want to send it back for repairs instead of a swap
Mine too

I would have thought it's a software problem. I have noticed this too and now it bugs me. You're right, the first startup screen, it IS pure black, but going to the next animation, you can clearly see the red pixels come on when it's supposed to be black. But because it CAN do the black on the first screen, doesn't that mean it's something else?
Please let me know if you are able to get a replacement phone that resolves this issue. I think I have a few days to return mine, but you'd actually never notice it in most times of the day. You have to be watching the phone in pitch black to see it, and probably looking at a mostly black screen. But it seems like more that you're not getting the benefit of energy savings of "off" pixels.
There is a totally noticeable red tint to the black.
Rgds
It could still be a software problem, but then a lot of other people would suffer from it as well. I guess its just too unnoticeable. You really have to be in pitch dark, but once you know, it keeps bothering you I'm not sure of what to do. If the store says it will do a swap, I'll swap it. If they want to bring it in for repair, i guess I'll wait a bit for an update (another user reported that it fixed his problem).
Still, if its just a few reports, shouldn't it be some kind of defect, right?
I would really appreciate if other readers in this thread could check their phone for redness, regardless the outcome, please post your result and firmware version. Thanks
BTW, you can get an entirely black screen by
Dialer -> type *#0*# -> Vibration
Ignore the vibration and wait for your eyes to adjust from the bright white screen. Its hard to miss.
Have you seen this post?
Somebody in this thread mentioned black being a bit reddish (not turned off) and no smudge issue. After flashing another firmware the reddish was gone (pixel turned off) but now he got smudge instead !
So yes - I think it could be something do with delay turning pixel on/off

Yeah, saw that too. Still weird Samsung tells me to go to the reseller if it is fixable with firmware. Having said that, shouldn't a lot more people be affected when it's a software issue? Good thing is, first boot screen is all black, so it's not the screen imho
Apparently the Note 2 also suffers from this:
http://forum.xda-developers.com/showpost.php?p=38280924&postcount=8
Nb
It is hard to notice in a bright environment but once you know it's there you'll always see it.
Power savings, extra wear for the red subpixels, and non-black blacks = lower contrast. This needs to be fixed.
can people having red pixels issue check for screen smearing ? if im right then people with this red pixel issue wont notice screen smearing effect
Someone with the red subpixel problem should test for smearing.
If it doesn't smear, try flashing the same firmware as someone that has the smearing problem and see if it fixes the red subpixel problem.
This will confirm if both problems are hardware or software related.
Just got off the phone with my retailer. They are going to investigate the matter with Samsung (emailed them a picture) If it's faulty, it will get swapped. I will keep you updated.
Recieved a call from Samsung; they are not aware of this issue, but they are going to investigate the matter. In the mean while, i can exchange my phone, as they will consider it a DOA.

This is a pretty big deal if Sammy says your phone is detective and needs to be replaced.
I'm afraid under this situation, there are quite a few S4's that need to be swapped out.
Good luck with the new one! Let us know how it is.
Allright, redness is gone, but now i have the screen smearing mentioned in http://forum.xda-developers.com/showthread.php?t=2252445. I am appaled :/
Same firmware versions, everything the same. Samsung has serious screen issues.

i told you just few posts back as of now it looks like either red sub pixels or smearing issue. its upto the people to choose. lets hope this is due to software.

Hi Guys,
New to this forum. I recently sold my one plus due to the exact reason but this was at the bottom of the display. Many have said that it would disappear over time but after 6 months, the yellow band was still haunting me. Gave up because of how infuriating it was and sold it. Got this beast, loving it but I noticed straight away at the top left of the display there was a yellow spot which spreads slightly to the centre. Im not familiar with the characteristics of certain displays as I am aware of the different kinds of displays these two devices use. Just wondering, would this problem disappear over time ?? I saw this post on this particular "fix" sites, which says that it will over time given the glue dispersion from heat and what not. BUT, im just afraid (skeptic here) it would end up like my one plus. Im trying to avoid going back to the reseller as this phone was purchased from a grey importer. Any input from any of you guys would be greatly appreciated. Thanks in advance!

a lot of people have yellow spots . the spots are mostly visible in 0% brightness and grey backround. Install dead pixel detect and fix and choose gray from the menu. if the result is not good contact with lg service center to change the screen.
you mentioned also oneplus. I also had oneplus before. it had 2 issues the first one was the led light bleeding and the yellow banding. the led bleeding is only visible down due to the position of led lights of the phone and cannot be fixed. the yellow band was due to the glue that didn't properly fixed. I personally had this issue but after some months It was fixed by the use of the phone. I also let it 2-3 times under direct sunlight for 20-25 minutes.

Just wondering, would it work if id put the Flex 2 under the sun as well? The discolouration is only noticeable, like you said, on Grey background.. wonder if this would go away over time.. thanks again!! :crying::crying:

you can try it but I don't know if the glue is the issue. on the other hand lg has a very good service maybe it can replace your screen if the problem is so obvious

hey, i managed to exchange for another one. Though there is some improvement, the yellow spots are still apparent albeit less noticeable and only in Grey background. Did your's disappear, or at least improve overtime? How is it? I have tried using a 38W UV lamp for nearly an hour and the yellow spots are still there..

Hello people,
Well, like the title says... I'm having the screen burn-in problem on my Pixel.
It's not affecting only the navigation and notification bars, but some icons and widgets from home screen too.
Is there a way to fix it or minimize it? I tried inverting colors and decreasing the screen brightness, it seems to improve it, but the "ghosts" are still there, even though they are visible mostly on white or grey screens.
It's very disappointing, I don't know what to do. There are some "burn in fixer" apps, but they basically invert the colors too, but I've read that they actually burns all the other pixels. Is it harmful to use them?
Thanks!

No it's a hardware problem..
Invert colors and increase the screen brightness, don't decrease it. You want that invert to make the pixels' lighting decay to match the rest as fast as you can. Do that for a few days and it should even out a bit at the cost if making all your backlighting decay a little (it won't be noticeable, but that is the effect).
There are apps that claim to fix burn in with good reviews on google play. Whether they actually work I not I've no idea.

Screen burn in is a part of OLED displays and it is actual wear of the organic light emitting diode...unfortunately there isn't really a way to fix it but to burn everything else in equally (but the output in general will decrease). The higher the intensity (brighter the screen) the faster it happens.
Unpopular opinion, but I prefer LCD's for this reason (no burn in, flatter power efficiency curve).
I've replaced the screen. Bought a new one from eBay. It is great now! Unfortunatelly it was the only thing to do, and thankfully the Pixel has a great building, you can easily replace the screen without disassemble
the whole device.

How did you replace the screen and how expensive was it?
About 100 USD. There's a lot of videos on youtube teaching how to replace it
Long story short, but this thing calls for some details to make a better description of it.
I took a bike ride today – placed my N10+ in a small, soft fabric bag and put it into my bike's side bag, set my music on, BT with over_the_neck headphones and there I went. Totally unaware of any phone problems, no BT interruptions until I came to a spot where I wanted to try camera and pulled it out.
Turned it on and... a horror, the screen looked totally dark with a deep shade of bloody purple and when looked at different angles it was showing a gold, and green etc glowing shades as if the back of the phone was applied on the front screen. Very dark, I couldn't see much at all, barely recognizing the fonts.
I checked the settings, the screen was still set to adaptable brightness(and it was @ max), accidental touch was on and there was nothing I could do. Was trying to find any RGB settings in Dev. Options – nothing there. And, mind you, the screen dark as hell, squinting my eyes to see any details on the screen. Did reset, twice – still nothing, shut it off and headed home. Factory reset was number one on my mind, but before that, I set my tripod at home to record the screen behavior after turning it on... and..., the reboot was normal, everything looks normal now.
But I'm left with a burning question: WTF was thaaat???
Have you ever heard about OLED/AMOLED screens doing that? Is it a known, fixable problem?
Been using this phone for two days. Now am gonna have to spent hours with their Customer Service that sucks..

Thanks for 'heads up' no, my problem was different, the entire screen opacity went totally dark with very intense colors of purple, burgundy red etc, then in different angles: yellow, silver but very ghostly looking and highly polarized. The display to read from was still there underneath of it, but almost impossible to see, like there was a heavy paint splashed over it. Too bad I couldn't take a pic of that. It will probably happen again, these things usually get worse with time.

:laugh::laugh::laugh:Just got back home and am reading your posts guys and started laughing crazy, yes, these f glasses! And now I can reproduce that "major screen failure" at will - with the glasses. I bought those cheap sunglasses (zzTop) yesterday and just for the bike ridding because they're big to protect my eyes from bug swarms and not for regular use so I had no idea. That was the first time that I saw the display with those glasses. A 'major failure' of my own. I'm still laughing it's funny. Thanks again guys!

Hi there,
I recently upgraded to an LG Velvet 5G running Android 10. For the most part, it's been great, but when I set a custom image as the background of the lock screen, the clock font keeps changing from white with no outline to black with a white outline. At first I thought it was just the pictures I was using but it doesn't seem to make any difference; if the text is on a light background it still sometimes appears white and vice versa. I also wondered if it had something to do with the automatic night mode setting because it seems to change around twice a day, but disabling that doesn't make any difference. Is there any way to disable this feature? Google searches and digging through the menu haven't helped so far. I'd be happy with it always remaining one or the other or being able to choose which it is, if that's an option.
Thanks!

Hi, benpeltz.
I'm on a Velvet SD845 not a 5g. But I've noticed it a couple of times.
I had a G8X before it and it happened a lot more so I think it's some kind of LG bug.

LOL, no problem.
Oh, may I ask you something regarding your Velvet?
Either I'm going crazy too or experiencing a screen issue.
It seems mine has kind of a greyish screen....I know it has a pretty bright screen, but It seems like the blacks aren't really black.
And when I pull down my notifications bar while having something like a movie, or a YT video or even my Settings, the notification bar gets really stained in grey (with the black around) where there's something written in white. Idk if you can understand what I'm trying to say, it sounds confusing and I'm not a native English speaker lol.
But I can try to record it and post it for you.
Anyway, you're welcome and thank you in advance!

Have you tried changing it to "Vivid" screen color? Settings->Display->Screen Color. Personally I felt like all the colors were a little washed out before I did that.

I actually did. But it's not just the colors that seem washed out...it's this thing that when I have a black image with bright letters or a white image surrounded by black it makes a grey stain around the white. I'll post s screen record so you can see it. Man, it's killing me not knowing if I'm crazy or it's something normal, although it's pretty ugly and annoying for me. LoL
There you have it. Hope you can understand me better. It not only when pulling the notification bar, but also during videos or even when using a simple black wallpaper with a bright detail in it.

Are you referring to the "frosted glass" effect, where you see the background faintly behind the drop-down menu? If so, I certainly get it with the drop down but I don't get it when I'm playing videos. I'd appreciate a screenshot of that to make sure I'm tracking with you though.
