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:

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.

Im having the reddish tint too.. makes no sense if its not a software problem.

I've got to the conclusion that my S6 have some screen glass 'problems'. Whenever i tilt it the colors change a little, from that yellowish white it goes to some blue accent; and also the botton of the screen is more white then the top. This is very noticeable indoor with brightness on auto, at the outside i don't really notice some of these 'problems'... I know that all of these things are specific to the amoled category but sometime it's irritating.
I've send an email to the carrier from i bought the phone and they told that the phone will be send in service; and replacement its not possible(i have bought the phone online).
My question to you, should i send the phone to the service ? I mean, it is two weeks old.. will it be the same after a screen replacement ?
I'm knox tripped also but i think this it's not gonna be a problem since it's a hardware issue.
Thanks for your time.

If you're knox tripped, then good luck. You still have warranty (in EU at least) but got to fight for it.
I got pink dots all over my front camera (getting worse and worse) and Samsung say the reason of the pink dots is cause of root, even tho there is documentation for it being a hardware issue on SG6.
So well, if Samsung can get you to pay for the repair in any way, they will.
I wouldn't bother. A repair will come back the same or worse.
Colour shift is normal but still one hundred million times better than any LCD. The white balance is AMOLED all the way and they ALL do it (on S6 and note 4).
I would learn to live with it.
i saw a post whether it was here or a different website. someone posted about a yellowish tint. i never noticed it until my roommate got a phone after i did. after looking at his phone, his looked alittle whiter than mine and knew based on the post i may have gotten a yellowish defective screen.
i went on order support chat and explained to them that i ordered this phone at the end of october and that it appears defective. at first they were willing to replace it for me either by sending it to them and they send me another or pay a fee for an advanced exchange and they send me one first.
i explained i purchased this 2 weeks ago and it should still be covered. after which they gave me a code to get a new one without charge. so i ordered the phone and clearly saw a difference that i felt compelled to send to everyone here my results. please refer to the attachments to see the difference.
this could be the reason why battery life was 2 hours of screentime, but i havent had time to test the new ones battery till now
+1 my phone is having the yellow tint and i don't think here in India it is easy to get the phone replaced! i raised a compliant with FlipKart(the online retailer) and they have given me a 2 weeks ETA.
so what i did also install this screen balance app and improved my white balance and it feels better or I have kind of got used to the yellow tint.
when i put my iPhone 6 next to the my Moto X, i can see that Moto X has a yellow screen! wish it was better...
Good luck getting this replaced if you unlocked your bootloader, despite this is clearly unrelated to the bootloader unlocking!!
Honestly, I like to having yellow tint at someday. It giving my eyes easier to using device.
But having a defective device is like cancer affect lifespan. I'd replace defective devices.
There's so many phones out there with that yellow tint. I had to replace Four!!! MXPE s to get a normal white screen..
So yes, what I expect from my hypothesis was correct and my battery is much better

Thanks for this post. I ordered mine from Amazon on wed, got it on thurs and immediately noticed the yellow'ish whites on it. I couldn't get past it so contacted amazon and got an overnighted replacement. To my luck the new one did not have the yellowish screen issue, white is now white. But I've read a bunch of posts on this and they seem to be correct. It's not a defective panel so much as it is a wrong color calibration. I tested this by downloading a screen adjuster app (Screen Adjuster FREE) and adding more blue to the screen calibration and to my surprise the colors looked white again. However, I shouldn't have to use an app to accomplish that. It should be done correctly from the start.
For those who are rooted and running a cm based rom, this may help.

Does anyone have a pink tint to part of the screen? I know the Galaxy s6 had a bad problem with this. I'm hoping it's been solved in this generation.

No pink tint on my S7, but the screen is not uniform. Bottom right corner is what it's supposed to be, with white background, but the upperpart has a yellowish tint to it.
Going crazy with these AMOLED screens, because last time I tried to buy a S3, I had to cancel my purchase after 3 units. They all had the same problem and I really tought, that Samsung could produce good screens after so many years, and because this isn't that much different with S6's screen
My Verizon S7 just starting displaying this problem. Bringing it back to Best Buy ASAP today.

My flat S7 has a bad screen too : Pink / Green color shift from top to bottom...
I already had this problem with 3 different S6 so I'm really disappointed the issue is still present with the S7. Got a RMA but it may takes 3 weeks for a replacement thanks to the ****ty consumer service in my country .
Here is a shot of the problem (the 2 shots are the same I have just augmented contrast on the second one to clearly see the problem).

I'm quoting myself from another thread. Still an issue... I'm waiting for a replacement model right now and I hope the screen will be good.
Yep, I've got this issue. Pink tint at the bottom of the screen. The only negative of an otherwise faultless phone. I kind of wish it had an IPS LCD, seems these AMOLED screens are very inconsistent with colour. At the moment it's not TOO bad but I'd prefer a uniform display. Didn't have this issue with the S6.

i have to exchange my amoled phones ALWAYS a few times (ordered my 5th S7 Edge today)!
i wrote a few threads regarding this, i also sent a message to displaymate (because they test "cherry-picked" devices, and do not mention this), see here: http://forum.xda-developers.com/note-4/general/note4-amoled-screen-quality-t2906365
1st: display not good compared to second device
2nd: the device i use now. very good viewing angles and no tint, BUT: left side of display is darker then right side
3rd: display strong yellow tint
4th: display almost good, slight yellow tint. would take this, BUT: front cam takes blurry pictures compared to other devices...
5th: ordered today!
you may think i'm a hypocrite or have OCD, but it makes me mad that a 800EUR device has such flaws!!!

I absolutely agree with you guys. We are paying a significant amount of money and we expect it to be perfect.
Kudos for keep trying @TML1504. Hope you get a perfect one this time.
Are you buying this from a local store or a online seller? Because all local stores in my country will ask too much question if I approach them for replacement since it's a silly issue related to display, software, speaker, camera. Mostly likely it will end up in a pointless argument from their side and they consider the issue under warranty only. Speaking based on my earlier experiences.
Are the screen tint issues happening straight out of the box or do they develop over time?
Are you guys noticing it when the display it tilted or even in straight position?
I got a replacement unit yesterday, but had to wait almost 4 weeks for it. Didn't get a DOA replacement at the store, because the store manager didn't see the yellow tint. This new unit has slight pink tint on the top part of the screen. Gonna wait till thursday and decide if I'm gonna change this one. Probably not, because with my luck I have to change phones too many times, and the store manager doesn't want/or can't see the problem.
Maybe I'm gonna forget and get used to this screen, because it's little bit better than the first unit. Driving me crazy that Im so sensitive to this kind of things

Same issue here. Been speaking to Samsung's UK arm on Twitter and they say to take it into my local store (even though it was bought elsewhere). My worry is that I'll make the trip and be told there's nothing wrong.

galaxy s7 screen problem
same here i preordered a galaxy s7 and after 1 week of use i started noticing some color shiftiing when i'm in a dark room the auto brightnes turns the light down
and i start noticing ( especiallly in grey, grey dark and green dark cloros ) that the left side is brighter than the right side .
it's like a wave of light from the bottom left to the upper left of the screen this is really annoying when using a grey theme for example .
i compared to a galaxy note5 and s6 and they also have the same problem but in different parts of the screen.
i can't return it cuz the people in samsung want notice the problem. and they will tell me there's nathing wrong with it so i'll keep it until next year.
and by th way i had the same problem but it was pink on the right side whit my s6 last year and i changed the display twice under waranty, the third try i've got a farely good display.
maybe the next year i'll buy an iphone.

Yep, picked up and replaced by Samsung UK within five days. New unit had a perfect screen
I hope that it's viewable in the linked photo but my girlfriend's phone is now showing a line on the upper half of the screen, has anyone else had this issue?
https://drive.google.com/file/d/1C6CrLFnZjazACJk_nNwqeg-UgoPU_wqZ/view?usp=drivesdk
I can't see anything
I'll have to see if I can get a better picture of it, it's a solid line that's visible with white, green, and blue backgrounds.
I can't see it in your picture, but I did have screen burn in on my Note8. The bottom navbar and 2 homescreen icons burnt in pretty good. Luckily Samsung was really quick on a LCD replacement. Contacted them, shipped it in on a Thursday and had it back the following Friday. I'd say reach out to them! My phone was a pre-order, so I assume one of the first batches. Best of luck!
There's definitely a something funky going on with your screen. There's a distinctive line running about 1/3 of the way through. Lighter on the-left, darker on the right.
Screen issues.
Hey I just wanted to say i have the exact same issue. I don't have a dead pixel right on the line but I've noticed that no matter the brightness or even the resolution I have my screen on there is always a line of discoloration at the same exact spot. I have contacted samsung and it's under warranty, I just have to get to a store to replace the screen. I wish there was an easier way I could fix it instead of me having to go out and get it repaired.
