Screen: white bands between pixels? - Motorola Photon Q 4G LTE

I bought an used photon Q from USA, perfect state but I want to know if the screen is ok or damaged:
using the brightness at high or maximum value I notice a strange effect.. I see light color lines between every 2 line on the screen.
I easily notice this effect on gray pages, for example in settings.
For example If I have an uniform gray image on the screen, I will see between every 2 gray lines a little white line..
Using "screen tester" from market I can easily notice that it happen only with gray, other colors seems okay, but I slightly notice also in more complex images with complex colors..
Is this a problem of my device or is a "problem" of all photon Q screens?

No one can help me? :crying:
I would like to know if other photon Q have this problem!
It seems like the problem is present in all color combination, not in pure color like pure white, pure black, and pure red, green or blue.
When I mix 2 of that colors I get something like:
XXXXXXXXXXXXX
XXXXXXXXXXXXX
XXXXXXXXXXXXX
XXXXXXXXXXXXX
or
XXXXXXXXXXXXX
XXXXXXXXXXXXX
XXXXXXXXXXXXX
XXXXXXXXXXXXX
XXXXXXXXXXXXX
XXXXXXXXXXXXX
It seems like the screen can't make all 16million colors, and to get the correct color use different colors in the neighboring lines.
This problem is more visible with high brightness and looking at the screen closely.
(I try to use a magnifying glass and the problem is obvious).
Someone can check his photon Q screen?
You can go to android settings and see if the black -> gray background have this strange effect...
I need to understand if is a problem of all Photon Q or if is mine defective.. I have to decide whether to return the phone in the U.S. or if I get refunded the cost of the screen and try to change it by myself

Here is a photo of the issue: http://imageshack.us/a/img547/5474/uhkg.jpg
You can see that the "gray" background of the brightness settings is not uniform, you can see dark gray lines and light gray lines.
You can see this also without magnifying glass and with your own eye..
In some photos seems to see a grid.
it is as if the subpixel grid is not aligned or something similar.. :silly:
I only need to know if you have the same "issue" with the screen or I have a defective LCD, so I can decide what to do! Please someone can check his photon Q screen and answer?
Thanks! :good:

have you anything changed on the display settings (desnsity or something with the colors ?)
its hard to say, it could be a display issue but i dont know really here. mhm

Until I read this thread, I didn't notice anything wrong with my display, and now I see the lighter-colored lines too. I don't think it's anything that will be fixed by exchanging the handset, but it's also not that big of a problem for me, either (I have to bring my Q really close to my face to see the banding). I wonder if the issue is more noticeable on that particular handset, or if you have really good eyesight (or maybe a little of both)?

I was kind of thinking the same... perhaps the OP is expecting perfection even down to the individual pixels... and that is just not going to happen.
Remove the magnifying glass from the screen, should work fine

Ahahah thanks for reply!
but I can see the lines also without magnifier!
I used magnifier only to make a decent picture

If you look at it from a distance, I doubt they are very noticeable.
Honestly, if you're really picky about screens - why did you get a Photon Q? The screen on this phone is not the greatest, I think everyone knew that when purchasing it - they were not buying it because it had the best screen.

I didn't bought this phone for the screen, but I was expecting a decent quality for a 2012 phone.
This not seems a normal problem, some lines of pixels seems damaged or something similar.
The problem is visible also at 20-30cm distance from the screen, the colors are not uniform, the images aren't sharp and in some cases I can see these lines.
At 50cm of distance I can't see these lines, I do not want to look at my phone from half a meter away.
The bad lines colors that I see are rendered by the pixels, is not a problem of matrix or distance of pixel or similar.
I simply want to know if you can see these horizontal lines on the screen, for example in the facebook logo, at 10 - 20 cm of distance.
Perhaps there was a stock of defective screens.
If my screen is defective I'll replace it in the future, if the problem is the bad quality of photon Q screen I'll stay in peace.
I don't understand how it's possible that the screen draws these lines, it seems stupid! The phone can control every single pixel, why draw these lines? I have never seen similar issue in a screen, even in the worst

Well, my Q is dead so I can't really tell you. What I can tell you, is the screen is not the best. It's just "OK" in my opinion.
This is my first native Android device, so I don't have a ton to compare to... but reading about screen tech, this device is not on the bleeding edge by any means.

Yeah, they say that the screen is not good because of the "low" resolution compared to the full HD and HD ready display (galaxy S3, S4, htc ONE, ecc..) but they say that the quality is good for an LCD, images are sharp ecc.. ecc...
I found this image on google: http://cdn.gottabemobile.com/wp-content/uploads/2012/08/Motorola-Photon-Q-4G-LTE-Review-display.jpg
Here you can see the single pixel but these lines are not present. Now I try to take a similar picture (I don't have the original rom but the issue was present also with original rom, also with recovery etc.. so is not a software problem).

From 20 to 30 cm away, I don't see any banding on my screen, so it's possible that you do have a bad LCD, or at least a less than perfect one. However, from what I've seen of the problem from the pictures you've shared, if I had the same issue I would probably just put up with it, especially if the phone is great otherwise. On the other hand, what bothers me and what bothers you are likely to not be the same. So use your best judgement on whether the lines are bad enough to justify replacing the "faulty" device.

I have noticed exactly the sam effect on my Moto G. You need very sharp eyes to see this but with hight brightness it is there. Pure colors are not effected. Gray and light blue colours are mostly effected. I presume this is normal to mix different colours.

Oh god, dust and dead pixels are my ocd's worst nightmares. I get so depressed when I see them Color Banding will soon be joining them too
You should add a no issue selection.
how?
Wheres the "no problems" option?
Mine has very minor light bleed, but thats it. Its only noticeable if I'm looking at a pitch black screen in a dark room.. so its pretty much no problem
Only issue I'm having is that the screen is too bright for the auto brightness.
Other than that it's perfect
No issues. But there's no option for that in the poll.
Gradient banding and light bleed (bottom right corner).
I have a yellow screen. But for me, I am getting intermittent screen flickering, specifically in Chrome and Messages.
Furthermore, I already have tons of micro scratches on my screen. Have no idea how they got there. Glad I picked up a screen protector for $3 on amazon and Ordered a Seidio Active Case also. Don;t want this beautiful screen to get a jacked up.
No issues here either.
No problem at all here! Gray one X.

You could try Juice defender. It has an option to change the auto brightness, both the maximum light, and the average light (and minimum)
Only thing I miss there is an option to disable it while charging or in the car.
My only issue is banding. For those who DON'T have banding, I would appreciate if you'd check out my thread on the issue, especially if you're able to post a photo of your phone's screen.

I don't think so. Take a screenshot when you see banding, then look at the screenshot on your computer or on another phone. When I tried that, I saw less banding on the computer and on my old Captivate than on my One X, viewing the exact same image.
I have banding, but it seems more like a software bit-depth issue than a physical problem with the screen.

Guys, I wish it were this simple, but it doesn't appear to be. I can use Paint.NET to make a gradient, and view that same image file on many screens, and my One X shows more banding than the others. It still doesn't look as bad as the One X's app-uninstall screen, which is likely because my gradient is linear and theirs isn't, and so on top of there being bands, they're also unevenly spaced! But there's no denying that the bands are there (at least on mine), and they're more apparent than on the other displays I have access to (another phone, a laptop, and a TV).

I meant a driver-level firmware issue. When I had the Nook Color, there was a kernel that enabled lower bit-depth to speed up the boot, but it introduced banding like this. There was another kernel that could show full 24-bit color and had no banding.
So just loading an image onto the phone isn't proving that is a hardware issue. This just makes my argument stronger with the uneven banding being related to bit-depth and not hardware.
I have no screen issues! @TinyBoss I saw your other post and I have to say your banding does look bad. I was leaning toward software until I compared mine to yours and I'm thinking you have a bad display...

If you do NOT have color banding, please read!

To those who have no banding: Have you tried this? If you have, and still see no banding, can you post a photo of it?
How to see the color banding: go to Settings, then Apps, then tap on an app and choose "Uninstall" (you can still cancel, don't worry). This screen has a gray gradient that shows severe banding on my One X, especially near the bottom of the screen. And not just banding where you see the transition between one shade and the next, but there are (many) places where the stripes go dark-light-dark.
I took a picture of my One X on that screen (using my Captivate, handheld--not the best result, but it does show the banding). I also attached a screenshot for comparison (it'll only show whatever banding your computer display has).
Since I have two smartphones, a laptop, and an HDTV here, I decided to compare the banding on the four displays. Here are my findings:
Captivate (SAMOLED) - banding is almost undetectable at all viewing angles.
Laptop screen (Dell Studio XPS 13, LCD) - banding is somewhat noticeable, slightly worse depending on viewing angle.
HDTV via HDMI (Sharp LCD, low end) - banding is slight to severe, viewing angle matters a lot.
One X - Noticeable banding from all angles (viewing angle seems to be irrelevant to this screen, which is great).
The One X's screen is still the best I've ever seen on a phone. Let's not lose perspective here! I'm just trying to investigate this particular minor issue.
Edit: In case it's not clear, I compared the banding by viewing the same screenshot on all four displays.
That looks more like how they are displaying that particular screen than anything hardware related. Otherwise we would see those bands everywhere.

It has to do with that particular screen because
It's a linear gradient--stripes are easier to notice,
the start and end colors are not very different,
the gradient is large.
Points 2 and 3 mean there are fewer intermediate shades, and they're stretched out over a larger area. So, yes, that screen is a challenging image for a display to render, but that's exactly what "color banding" refers to--how well does a display cope with such gradients?
If you think it's not hardware related, just take a screenshot, and view that image file on your computer or another phone. The bands are less noticeable.
And again, I feel like I need to repeat that this is the best screen I've ever used, and I love it. I'm just trying to get a handle on this one issue.

My understanding of color banding is that it is not so much a function of hardware, but one of software. It depends on the number of shade of a color available. The fewer bits available to display different shades, the worse the banding would be. I'm not very good at explaining it, see wikipedia for more: http://en.wikipedia.org/wiki/Colour_banding
My point is that I don't think that it's a defect of any sort. I think that what we're seeing (I checked mine in the uninstall screen and there's some slight banding) is that gradient from light gray to darker gray is probably a low resolution and low color resolution graphic.
For another example, go to this page:
http://tomobriendc.net/images/Green_Gradient_to_black.png
That's a higher resolution image that gradients from green to black. When viewed at the default browser resolution, I see absolutely no banding. When I zoom in to have the image fill the screen, which puts it stretched, I can see very slight banding in the green end. Further zooming increases the banding, but by then I'm zoomed far past the full size image.
I guess what I'm trying to say is that I think this is a non-issue. The amount of banding visible (if any) has at least as much to do with the image you're trying to view as it has to do with the display. If you don't get color banding in pictures that you take, or in the UI that you use every day, then I wouldn't worry about it in the slightest.
Alright guys, I know what color banding is, and I think I was very clear in my first post that I took a screenshot, and viewed the same screenshot on four different displays. This is not about software, bit depth, or image resolution. It's about whether this display shows more color banding than other displays.
And I do agree that in typical use it's a non-issue.

Of course you do. People just got their brand new gadget that they've been looking forward to for months, and will be living with every day for a year or two. Naturally they want to poke around and check out every little detail. At least some of us do anyway, and we're probably over-represented on forums dedicated to phones!

It is a screen capture, and it just means the display you're viewing it on also has some banding. I see it on my computer display, too, just not nearly as much as on my One X.

Nowhere in OP does it say you used the same picture across all displays.
Regardless, this is a software/image dependent "issue." You can see banding on any display, regardless of whether it's a 20 year old CRT or Samsung's brand new $9000 OLED TV. It's a NON-ISSUE.
Banding
I also think this is a software issue. However, the screen shot the OP posted of his One X looks way worse than mine does. Mine barely has any of the banding and is mostly black all the way through other than at the very bottom. It just doesn't progress upwards like is does. However, if you dont always see the banding on a black screen then its in the software. Take a picture of something that is completely black or do a screen shot of something black and view it in the gallery and if you don't see the banding then this is obviously just the particular uninstall app causing this.

lol SOOOO wrong. Unless you've got your computer display set to 16-bit color or less, it's got NOTHING to do with the display on your computer.
It's 100% software related. It'll likely get fixed. When we got ICS ports onto the DHD there was banding, far worse than these pics, and it was fixed with an update.
Yes, different display types can ACCENTUATE the issue to various levels, but if the software were rendering everything right, you wouldn't see banding, no matter what display your device has.
It's all about the pixels. If the pic has less pixels then the actual screen resolution you will see that the banding is greater, because ICS is made to stretch to all phones that's why it's more noticeable on larger devices.

Yes and no. It's image-dependent only in the sense that certain images are more challenging to render correctly without banding. I realize other displays have banding (I know I was clear about that in the FP), but I'm just saying this one seems to have it worse than most.
Look, all I'm trying to do is investigate this one, minor area where my phone's screen seems to have poor performance. If it's only mine, then I'll exchange it. If they're all this way, then fine, it's still the best phone display I've ever seen, and I won't worry about it. My Captivate's display has almost no banding, but I'd be retarded to prefer it over my One's.
All I've been trying to do is determine whether there's something wrong with my screen, or if it's just how they are. And I'm pretty sure it's the latter. And that's fine.

You do realize the reason that your Captivate shows little to no banding is that the black pixels of the display aren't even on, right? So the Captivates blacks are truer than the One X's, but our white is more true than the Captivate's white(blue). No display is perfect, other than the ones on your face, so why bother stressing over it? If you never had any device to compare to, then you wouldn't have a single thing to have a fit about. There are going to be discrepancies and every display is going to have trouble doing at least one thing or another, nothing's perfect.
On top of that it has to do with the grade of the gradient and how quickly it's changing shades of colors. Say you're making a black to white gradient in 20-30 passes, 20-30 changes basically, it's going to be choppier than one with 100 or whatever. If you don't give it adequate time to make the change, then of course it's going to band. It's just like animating. You can't expect a 15 frame animation to display a full action scene in any bit of smoothness. It takes 100+ frames to do 3 seconds of visually smooth animation.
The banding is LITERAL BANDS of color on the screen.
The galaxy nexus does this as well on settings and a dev fixed it by updating the image used within the settings app. I'll see if I can find it.
Edit: http://forum.xda-developers.com/showthread.php?t=1588613
I have a reasonably simple solution to this issue ...
Maybe I'm wrong, or I don't quite understand the issue, but I think I have a simple solution to determine if banding is really an issue in this regard.
I'm preparing four images, which I will upload in a ZIP file along with instructions.
Give me about 10-15 minutes.
Peter
---------- Post added at 02:58 PM ---------- Previous post was at 02:46 PM ----------
Clicking on the link below will download a ZIP file called Banding. Extract the four images and place them anywhere on your device.
http://www.sierrabeyer.com/TempImages/Banding.zip
Now look at each image on your device and decide whether or not you see banding. If you do, then the unit DOES suffer from banding. If not, then it's simply an issue relating to the image used by the developer for the background image of the screen your looking at, in this case, the uninstall screen.
Why can I make this conclusion? Well, all four images are simply 1280x720 pixels, the exact resolution of the ONE X screen. Also, all four images display but ONE colour. Okay, maybe not a colour since one is black (0,0,0), and the other three are shades of grey (32,32,32 and 64,64,64 and 128,128,128).
Here are full size images:
I don't see ANY banding on my HTC ONE X screen. Each image is pure black or grey.
Let me know what you think. Does this test resolve the issue, or am I completely off base?

Addendum: I have since learned that my reasoning is flawed. If I could remove this post, I would. My apologies to everyone.

Horizontal lines

Does anyone get lines on their screen it seems to really show up on light and grey colors. Its weird because it doesn't look like it goes from edge to edge its just where there is bright colors.
I attached a picture, my display just goes nuts whenever I have it up because of all the grey. I can see the horizontal lines at around 15% screen brightness and up.
Perfectly normal on a LCD Display...have it on my Nexus 7 (2013), Nexus 5 and noticed it on other devices like the LG G2...not noticeable unless you´re VERY close to the screen...nothing too bad

I can't believe this is normal, this effect doesn't show up on my computer LCD, and when I have that picture up you can see lines from far away on my phone.
Okay...I see you´re coming from the Galaxy Nexus, just like me...muuuuch better screen imo despite the lower pixel density..
But very noticeable Scanlines might indicate a GPU or Screen defect...small lines, barely noticeable may be just the digitizer you´re seeing...Again: Only speculations
I noticed these lines on my N5, but they´re too small to capture on a camera let alone see from a distance...
You might want to RMA or try other Nexus devices out..
I am looking at the image on a 60" 1080p display and I can't see any horizontal lines. I must be blind?
when?
sorry when does it happen to u?
Same problem for me.
Horizontal lines.
Barely visible on white or black screens.
Noticeable on grey tones.

Does anyone get lines on their screen it seems to really show up on light and grey colors. Its weird because it doesn't look like it goes from edge to edge its just where there is bright colors.
I attached a picture, my display just goes nuts whenever I have it up because of all the grey. I can see the horizontal lines at around 15% screen brightness and up.

Ummm...... That is a SCREENSHOT it will not show defects in the display, only what the software is "outputting" to the display, screenshots will be defect free.

I'm having the same issue with my N5. Have you found out if this is normal or a hardware defect?
Thanks!

Yellow screens - does the problem still exist?

There were reports of OPOs and OPPO Find 7a-s with yellowish screens. Could OPO owners or others with information clarify if the problem still exists?
Thanks.
Edit: Ok, there is some info from an owner.
The display doesnt have a yellow tint and furthermore you can customize the display using different presets (standard, vivid, custom hue/tint mode etc) but out of the box there is no yellowness on the display (i.e. the hardware display looks great)

Hi,
I received mine yesterday and I have a yellow tint at the bottom of the screen. There are also others who have this issue.

I contacted David and thinking about opening a ticket and replacing it by a new one, yes.
Here is another user with the same problem.

Yellow Screen: This is an update from yesterday. So, the yellowness is there a bit ... but it's barely noticeable. I really have to strain to see it, and honestly, it hurts more to try to see it than to just use the phone. At this point, I do not think I would return the phone just because of the very slight yellow shadow on the bottom quarter inch of the screen. It's practically invisible. I am hoping it just goes away completely like happened for some of the iPhones a few years back.

Confirmed by OnePlus in Jerry's post, there is a yellow tint at the bottom. Quote: "Since brightness influences color temperature, the yellow tint at the bottom is due to the design of the phone". This is not talk of an uniform tint over the whole screen, but a yellow tint at the bottom.

Apparently that was said by one of the admins. They confirm that yellow spots exist but deny that this is a problem. I think this is a product defect and should be exchanged by the company without questions.
What do you think?

I would insist on getting it fixed up if you have a that partially yellow stain. It doesn't matter how "great" the price is, if it's got such a visual stain. I wouldn't put up with it.
Say what you will about Samsung phones, at least the OLED screens looked fabulous.

I am planning to get the phone, but seeing OPO denying that yellow spots on the bottom are defects (they say it is normal), I will hold off for a time. It is really idiotic on their side to deny the problem and deny RMAs.
Just got my OnePlus One today in the mail, and to be honest I think people may be making this deal bigger then it needs to be, or I got very lucky. On my OnePlus One there is a bit of yellow tint at the bottom, but it is SO minimal that it strains and hurts your eyes to even look for it, and if you use on-screen buttons it covers it up anyways. And even if you use the hardware buttons, the amount of yellow is so little that you never rarely it with day to day use. Hell, my Nexus 5's minimal backlight bleeding on the screen edges is more noticeable then the yellow on my OnePlus One.
With that all said though... this still may be a hardware issue for some users, and if so OnePlus One should stand behind their product and offer replacement devices.

I know.
I can't believe a company that touts itself as having "beautiful experiences" would be so bad in the "customer service and selling experience". Noobs.
Got my device yesterday. Pretty bad Yellow staining along the bottom half inch of screen. Quite bad IMHO.
Requested a return/replacement
That's the same here. Received it on Wednesday, I've got the same problem as yours: yellow tint on the quarter-bottom side of the screen, that's worse on the right-bottom edge than the left-bottom one. Hoping it goes away but I don't think so.
Same here, very bad yellowing at the bottom of the screen.
Have asked if they will replace it, but they just send me a standard email that everyone gets:
Hi
Thanks for getting in touch! There are three different types of 'yellow screen' issues.
One is where the screen is evenly tinted yellow - this is actually an intended effect as warmer screens offer more true-to-life colors than bluish screens. To adjust your screen hue manually, please go to Settings > (under Device) Display & Lights > (under Advanced Settings) Screen Color > Custom > Hue.
Another is a slightly yellowish band across the bottom of the screen when viewed from unconventional viewing angles at full brightness. Our screens are lit from the bottom instead of from underneath, and to minimize bezels we place the light sources very close to the edge of the screen. To prevent excessive light leakage, the bottom edge is designed to be slightly opaque, which is why it appears yellow from certain angles.
If your screen has yellow spots that appear to expand however, please send us a photo and we'll see whether it's a hardware issue.
You might have seen photos of these issues online - most were taken at extreme angles and 100% brightness, or even doctored to increase the contrast. Actual imperfections are usually very subtle and do not impact normal usage.
Thanks for understanding
Best regards,
Marilyn
They also say the evidence is tempered with, basically calling us liars.
That response is awful. My screen is blatantly yellow and they are saying it's supposed to be like that!? I've sent a RMA request - will see what response comes back
Yellow on mine too. Got the device yesterday and quite displeased.
Bad QC from the supplier of the display. Either the glass was not cured long enough to the touch screen, or it was
rushed out without QC inspecting them for rejects. With the amount of orders requested in China alone, not to mention
the international demand, doesn't surprise me.
What's sad, is the stance OnePlus is taking. "you are holding it wrong, we did it for a warmer color display".
Crock of beans! It's a DEFECT when the bottom part of the screen is YELLOW.
Some say it will go away over time, but if you have access to a UV light, a little time under one of those might get
rid of it. Considering how long it takes to get one, sending it back for a replacement might take as long as it did
just to BUY one.

I can't see any yellow on the screen of my OnePlus One.

S8+ AMOLED Display Quality (Red Tint Issue) - worse as previous Samsung devices

Hello fellow XDA members,
In the past I started some threads regarding Samsung AMOLED display quality, especially for the Note devices.
Please see here if you are interessted:
https://forum.xda-developers.com/note-4/general/note4-amoled-screen-quality-t2906365
https://forum.xda-developers.com/showthread.php?t=2463786
Now, with the S8+ (and the S8, the problem is the same), even the media recognized the display problems, known as "red tint", just google for it!
Samsung tells the people that this is due to wrong settings, and/or the adaptive display setting turned on! THIS IS NOT THE CASE!!!
I got 2 pieces of S8+ today, and both displays are not OK. One screen has the red tint issue, but only on the upper half of the screen.
The other device has no red tint, but is generally darker and looks more "washed out" and has a slight yellow tint.
So again the display lottery is back, it is only "luck of the draw" if you get a decent screen or not!!!
If you do not believe me just compare a few devices beneath each other with the exact same display settings. Turn adaptive display off, then go into the dialer and type *#0*#, with this you ensure the brightness settings are the same and you have the same sceen content on both devices. You will notice that every single device has a different screen quality (tint, evenness, ...)
What do you say? Acceptable or not?
With all of us over at the tmobile shipping thread we've been waiting and crying and hoping that we get our devices early....and then when we finally got our devices ****ty things like red tint leaves a sour taste in our mouths..sad really, samsung already made this device feel rushed with all the Bixby and fingerprint scanner awkward positioning and what did we do after the note 7 debacle? We forgave these fools...and now this?....i do feel bad for those that actually paid full retail price for these expensive devices and to unbox and realize the screen is pink...that right there is not how to say forgive us for our mistakes instead a huge f u to all the customers who were unlucky enough to get such a horrible display color....but I will say I won the lottery because out of the box my s8plus came out nice no red pinkish tint whites are white...but why am I still pissed? Because my note 4 was the same whites were white and then after a year or so my eyes were fixed on a strange color that was taking up half of the screen that came out of nowhere...so yes I will be forever paranoid with sammys displays now....if my s8plus came in like that I don't think I would've came back....but then again I'm here lol
Settle down guys, this will likely be fixed with a future fw given the attention its gotten, this is pretty simple for samsung to fix actually, all samsung needs to do is what video games have been doing for years; offer the user an option to calibrate based a sample image. Once thats in, the presets can be established based off of those generated values from the user selection.
It seems like they will indeed need to implement a fix of this sorts, because it does seem the displays hue varys from device to device.
Anyways, for the most part, I hardly notice it and it seems even, and the more I look at it, the more i can't make sense out of it? Seems to play tricks on my eyes... lol.
Beautiful phone and display though!

This is a hardware problem, a real software fix IS NOT POSSIBLE!!!
Samsung can only try to cammo the problem with increasing the range of the color-sliders in the display settings, so that you can turn down red more then now. But this wont fix that the red tint is NOT EVEN ACROSS THE DISPLAY!!
What else proves that this is a hardware error is that if you put 5 devices next to each other (with the exact same settings), each of them will look different in regard to screen quality! Believe me, I know what I'm talking about, see my previous threads regarding that!
I agree that it should be even otherwise you may have a hardware problem but my concern is your criticism has more to do with amoled in gerneral and what we are observing is a consequence of the tech used. Samsung is also pushing the boundries here too with the display tech so the norms for amoled to compare to may not even apply anymore. And your comment to my comment regarding masking the problem, there is a reason why every display on the planet has picture settings.. right? No 2 displays are exactly the same...
I just went through the crap with my Surface Pro 4 too, trust me, they are a good example of no 2 displays alike, must have went though at least 11 Surface Pro 4 on my mission for perfection display and I had to give up in the end because truth is, its still an awesome device!

Absolutely unacceptable reasoning. They shouldn't be putting out a product if the "early batches" are DEFECTIVE
Obviously it's a QC problem, which they seem to have some fairly big issues with, over and over.. They will lose customer faith if they keep doing this ****

Perhaps but then again why did you buy a phone from samsung in the first place?.....
I was in the Samsung store yesterday for the launch party. They had 3 S8+ on display next to eachother. Each was running the exact same retail mode, showing the exact same content at the exact same time.
One display was white, one was red hued, and one was pee yellow.
(No, it wasn't display calibration settings, I checked).
There are definitely quality control issues.

And which of the 3 do you have?
I noticed a slight pinkish tint when the shipping screen protector was on, but looks ok without it.
Something slightly different this year is there seems to be a pink tinge on all four sides of the display (top, bottom, left and right). It's a very consistent along the sides of the screen and very noticeable, a few people here have also noticed it: https://forum.xda-developers.com/galaxy-s8/help/red-tint-screen-t3592335
So it's not just another pink/yellow/blue/green spotty tinge problem, theres now uniformity with the example i've provided.
I've got the S8+ and the screen is not red at all. The left and right edges if anything have a slight blueish tone to them but I believe this to be the effect of the screen curving to the sides distorting the colour (Colour shift?).
Unless you have bought one and have the problem with it, you have no right to complain.

Mine had a very slight pink tinge when I got it, at the very top and bottom (maybe half the status bar thickness), and it's since gone way.
The over all display color was a little too warm for my liking, so I knocked the red slider down to half, and now it's fine.
Got me and the wife one yesterday from At&t. No red tint and best phone yet. I love it.
My display is freaking beautiful and I love the fingerprint location. I never had any trouble. My finger finds it very naturally

im not tying to be a jerk but just curious what happens when you cycle the --blue light filter-- button in the pull down menu with the wifi, Airplane mode ect.
reason i ask my displays is perfect but with the blue light filter on which is to reduce eyestrain ..then the display is very red
Really did not know they had this till i play around with it

I have an S8+ as per my posts in the other thread, so I have a right to complain.
Firstly, it could well be fixed by software, even if its uneven, HTC had issues with the camera doing this a number of years ago (big red spot in all pictures). It was fixed with software
Secondly, it might disappear with time. AMOLED, OLED and other self lighting technologies (like Plasma in TVs) have a bed in time, where some colour ranges need to burn in. I would suggest a full red screen using a screen tester app for a few hours, to see if it beds in the red.
Guys, I would like to take this device, there is a possibility of having a faded display?
