Adjusting the colors of the display? - Xoom Q&A, Help & Troubleshooting

Is there a way to adjust the colors of the Xoom's screen? I'm pretty disappointed at how photos look white washed on the Xoom as compared to other tablets. The Galaxy 10.1's screen seem over saturated but their Touch Wiz update provided them a way to choose a setting which was more natural. I was thinking if they can do it through the software then maybe there is a way to better the colors of the Xoom's display.

I have xoom too, I agree with you, display is dull. How can we increase amount of brightness?

Some of you guys got the not so wonderful screen...I'm sorry. These's an app called Color Filter Settings in the Market that might help. Also Screen Filter might be of some use, but it doesn't increase brightness.

Thanks okantomi.

I've always wondered why someone doesn't make an app that allows us to modified the colors like gamma, Brightness, Contrast, saturation, etc. It could make any device look great.. maybe allow presets and stuff.

Hi there okantomi !
May I ask who's the manufacturer for your display and if any infos about the specs for that ? Part number will help a lot.
I'm afraid not only "some" of us but actually "many" of us have this crappy washed screen from AIO which drives me nuts for how bad it is.
Since I'm not the only one with these problems and AFAIK Motorola is aware of this I really don't get it why they don't even bother to release a firmware fix or at least create an App to let us playing with colors and contrast adjustments to increase a little bit the appearance on our screens.
Thanks for any replies.
Regards

I only recently checked and found that I have the Sharp screen, luckily without any bleed. My screen is great, but I'm not sure it's as easy as Sharp vs. AUO, because a lot of people swear by the AUO screen, like our moderator. I agree that there should be a fix available, because it's the one thing that's most consistently complained about by people with low contrast screens.

Thank you so much for your reply. I'm pretty sure that SHARP screens are much better than AUO ones based on their experience and history with this kind of stuff. I'm aware about those bleeding problems about some of them however I would preffer one with some bleeding instead this one with such a poor visibility and so washed. If you tilt the screen just slightly (few degrees) everything goes washed and color saturation drops a lot. What can I say..it's a real nightmare to watch this.
I like the overall appearance and features for this tablet, this is the reason I'm still looking for any solution to improve somehow the quality of viewing.
If any chance to get the part number from your unit I will appreciate your effort a lot.
Thanks again.
PS...about others with AUO screens and no major complaints...it looks like some of them are upgraded versions already (the latest XOOMS), so maybe that's the reason for not so many complains with them

I don't know the part number. Have you tried contacting Motorola to see if they could upgrade your screen or at least give you some information /options?
You might want to try that Screen Filter app. I think it could help you, especially with your viewing angles.

Mytouch4G screen color washed out and too bright.

Does anybody else notice that the screen colors on the MT4G are a little too high, its like the colors are too bright. I know that I can turn the brightness down, but right now I just have it set to automatic and I like that and I don't want to have to change that.
Does anyone know how to change the contrast on the MT4G? I just want to saturate the colors a little more. Anyone?

You can't do this on any android phone, rooted or not. Could you take a picture or maybe tell tmobile your problem, it might be an actual lcd problem.
Yeah I thought that I was the only one. Especially on this site when you view it from your mobile browser, the brown XDA heading is too bright and faded
I noticed it when I got my wife a MT4g. On her phone the colors are slightly more saturated and the blacks are slightly darker also. It is kinda bothering me now.
wanna see something crazy look at your phne for a minute and then look your computer the screen looks blue lol iyts true my mytouch colors are bright or must be my eyes

My wife is experienceing this as well. She went to look for the night time bedside clock app and found when the app turned the brightness down to 6 the entire screen went black, but at a brightness level of 7 the screen was dim, but still brighter than I would expect.
She commented on her Vibrant when the brightness was turned down it would go all the way down and have a black background, not a washed out dim gray background.
Hopefully there will be a fix coming.
I posted elsewhere that the screen, while obviously not as good as the Vibrant's, seemed to be just as good as that of the Nexus, Incredible, Eris, etc.
Well, I stand corrected. After reading your post, I downloaded 'Night Watch', and compared the look to that of my wife's Nexus. The Nexus does indeed appear to have a black background at 39% brightness, with vibrant green (color I chose) numbers. The MT4G appears more grey-ish, with less vibrant green numbers. Even when I reduced the brightness by another 5%, the MT4G was still grey-ish.
Now, I'm not sure if this is the screen hardware itself, or something in the contrast settings of the phone. It did bum me out a little, as I've been a pretty staunch supporter of this phone since I got it.
The dilemma is,
Do I decide to go back to a Vibrant for a nicer screen, but much fewer options? (not much chance of that)
Look to find another Nexus; and tak ea step back in terms of processor speed, ram, features, et.c (with the exception of the color trackball, which Nexus lords over ever other phone)
Wait until something better comes out; as there are no other android phones comparable to this one in terms of features, available by T-mo right now? (Wait? Really? Arggh!)
All in all, I'm very happy with this device. And maybe I'm just knee-jerking. But, in truth, it does bother me somewhat. Thoughts?

I know exactly what you mean, the blacks look grey and the reds look pink.
I think there is something wrong with the contrast balance in the software somehow, because it does seem like a nice screen, but those are just my thoughts.
I sincerely hope that this is the case. If so, perhaps some tweaking can be done in the settings, mch like, but nothng at all like, the registry settings change in WinMo phone, wherein the colors/contrast could be adjusted by assigning different numbers.
I realize that there is a huge difference between android and WinMo registry tweaks. But it's hard to believe they would simply included an inferior screen to go along with so many other hardware improvements.
its not an amoled display guys, it's never going to be completely black or have as high a contrast ratio as the nexus or vibrant.
Yeah, I know what kind of screen it is, and I know how others look in comparison, my point is though, my Mytouch3G had better colors. It just seems like something could be done via software.

It has only been out a couple of weeks, I would give it some time and everyone complain a little to T-Mobile and hopefully they can add it to a future OTA update.
I only had the MT4G for a night before returning it for a replacement (which is still in the mail), but I agree: The screen looked very washed out. It was so bad that I am now considering keeping my Vibrant.
I am not asking for SuperAMOLED-like quality, but something average would be nice... not low quality crap.
I'm starting to think there's production issues. The very first 2 units I saw had the washed out look. I saw one today that seemed fine. I went thru the menus and changed the backgrounds. Everything seemed much better on this one.
I wish I could compare them side by side, but these were in 2 different stores.
Thoughts?

I had been weary about the screen ever since I got mine last Wednesday. From reading reviews talking about how great the screen looked, and then mine was kinda... blah. First words in my mind when I turned it on was how washed out some of the colors looked.
I took mine back to T-Mobile tonight and swapped it out for a new and I have to say that there's a huge difference. Some of the colors are still a little off, but it looks like it's the app's icon and not the screen itself. Compare the newest YouTube app's red to the TasKiller's red, for instance.
Now to wait on the OTA so I can re-root this thing and clean it off.
I wish I had something to compare mine to. I went to the store, thinking I would compare mine to one of theirs. But it was a bust; as the screen looked exactly the same. So either mine is as good as the replacement you got, but just pales in comparison to the Nexus. Or it's washed out, the one in the store is washed out, and I'm still at square one. Unfortunately, there's no way for me to tell.
I took my MT4G back after running the Asphalt demo next to an Epic and Droid X. The colors were totally faded out and missing details seen on the other devices. The Epic is over-saturated and the X seems to split the difference, not to mention the size is awesome.
Hmm...
Well, being with T-mo, neither of those other two is an option for me. But, I'm thinking about it, and I'm starting to think our phones only seem to pale in comparison.
What I mean is, side by side, yes, they seem to be less-than-stellar. But when used on their own, they seem to be pretty alright... though obviously not as good as what our minds recall the others being.
If you look at a 60hz 1080p tv side by side with a 120hz edge-lit LED tv, yes, the original would look tame. But that's not to say that it doesn't look great on it's own.

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?

Improving viewing angles for Locked Bootloaders

Hey guys!
Good news for those ones who have locked bootloaders! Install this app: Screen Filter
https://play.google.com/store/apps/details?id=com.haxor
It works with White Balance and can improve screen viewing angles! No need custom ROM, specific Kernel or Root!
Try it!
Thumbs up for the developers of Haxor!
Just remember that the app works like as gamma control of DoomKernel, which also tends to darken the display.. Just see my other thread: http://forum.xda-developers.com/show....php?t=2710684
Cheers!
This is just wrong -.-
It's a screen dimmer just because when you dim your screen you can see some stuff better at an angle doesn't mean that you improved viewing angels
Doesn't work.

So, you say that "you can see some stuff better at an angle", doesn't that literally mean "improved viewing angles", which essential IS seeing things better at an angle? :laugh:
Yes I think dimming the screen is not such a great solution, but better than nothing. Technically, it does improve viewing angles to an extent.

The brightness level can be adjusted in the application, so that does not become so dark, you have tested?
For those who have the locked bootloader is a breakthrough yes! I invite people to test.

Not really a breakthough, I used this app about a year ago. Its nothing amazing...It just dims the screen, ideal if you use your phone as alarm clock in a dock and you cant dim the screen enough with the native brightness control. But that's it
And unsure why you think this is a breakthough for locked bootloaders. The app is compatible with android 1.6+ and has never needed an unlocked bootloader to work
This application works like this that was shown in the video of Anirudh Srinivas:

For me, it works better because it works on all display, including in the softkey area.

So, you say that "you can see some stuff better at an angle", doesn't that literally mean "improved viewing angles", which essential IS seeing things better at an angle? :laugh:
Yes I think dimming the screen is not such a great solution, but better than nothing. Technically, it does improve viewing angles to an extent.

What im trying to say is
Dimmed Angle is better when Dimmed
But Bright Angle is better than Dimmed Angle
The intent was to help people who do not want to unlock the bootloader. It is quite obvious that the app works for both Locked or unlocked bootloaders, needless to say. Let the people test.
Not everyone knows the application or have tried something like that, and not everyone here is a developers or advanced users.
I tested the app, liked and saw some improvement in the display.
Let's be more friendly here and less kicking in the colleagues ass ok?
Sorry, not having a go..just wondering why this was meant ot be a breakthough
Of course people can test themselves
Just remember that the app works like as gamma control of DoomKernel, which also tends to darken the display.. Just see my other thread: http://forum.xda-developers.com/showthread.php?t=2710684

Agreed....
It allows you to lower the brightness more than normal, WOW what a breakthrough.....
The viewing angles issue is a hardware one, sorry but lowering the brightness is not solving anything. The issue is using crappy tft technology. That being said it is still miles ahead of the original xperia z, the display on that was so bad I got rid of it after about a week.

Display viewing angle / hue shift

Received my pixel earlier this week.
Immediately after opening the box I was quite disappointed that the display noticeably shifts towards a blue hue even at the slightest change in angle other than straight on.
I have looked at a bunch of phones on display in stores since, some of which are showing similar symptoms to varying degree.
I understand that AMOLED displays are more susceptible to color shifts at different viewing angle but this seems very extreme.
Anybody else notice the same or bothered by it?
I notice it a little bit, but it doesn't bother me until at extreme angles. I figured it was just a characteristic of AMOLED displays, I see the same shift on my watch.

I have noticed the same on my device, 1/3 of the display at the bottom has a blue tint on light screens while holding it regularly, facing me. If I tilt the phone forward (not facing the eyes), it is better, but a very small angle change and that third of the screen is blue again. I have compared my device to another one and on the other device, it happens a lot less. Instead of just a third of the display it's the whole display that changes slightly color but in positions you wouldn't normally hold your phone. I am considering returning the device...
What have you done yourself? Do you think it is an issue?
Didn't notice until this post. That's probably because I had the same issue on the Nexus 6P. In fact, it ought to be better than this when Google are charging extortionate prices for this!

After 4 days of back and forth with play support they have finally agreed to exchange. I looked at a lot of other phones in stores and mine certainly seemed to be worse than most of them. Worth a try. Luck of AMOLED draw I guess.
AMOLED actually has the best viewing angles of ANY display, really. My 4K LG TV's look incredible from any way I look at them.
Pentile AMOLED as seen in today's phone screens is different and the cause of this issue. The color shift occurs because of the inconsistency in sub-pixel layout... RGBGR rather that straight RGB.

I have received a replacement phone and the new device hasn't got the problem as much , I guess the first device was slightly imperfect and I was noticing the amoled blue tint more coming from a LCD display before on my previous phone.
The viewing angles and hue shift on my lg v10 ips screen is worse..
It's the luck of the draw most manufacturers source hardware from different vendors resulting in slightly different variations. Ie the different ram used in pixels, making some slightly faster than others.

The pink screen

So is anybody got not device yet that doesn't require the red to be turned all the way down in order to look somewhat appropriate?

Red screen*
When I got this phone in my opinion it was clear whit but tgen when I tried reducing the red colour it became even more clearer, I don't know it's probably I didn't pay attention to the colour when I got this phone...
In my opinion the blue light filter messes up the display although I know this isn't the case..
I got a replacement new phone as I cracked the screen on my first one, and my new one, if anything is slightly cooler / bluer than I usually like, no red / pink issues I can see. My last one was ever so slightly reddish even with red slider down.
for me it is fixed after:
- specific sw update
- set adaptive display
- set display tone to cooler option (-1 or -2 from the slide bar in display settings)
Out of the box mine is fine. I swapped my first one that had a pinkish display even when red turned all the way down.

if i understand your question right then yes, there are devices without the ted tint issue!
I went into 4 shops and looked at 8 phones and everyone of them had the red /pink issue only 1 could you turn down red to reduce it in adaptive settings when it became blue/green white and all were red In photo and cinema settings
I bought my s8+ ten days ago, after two days I changed it because of pink borders... Before change, I powered on two new s8+, one were all red (not only borders), the other one was nearly perfect... But I had to choose another color (orchid gray) instead of my first black phone... It's a shame that we have to choose the phone from the color of display and not from the color of the phone...

My screen is pretty noticeably green-tinted, but it somehow gets corrected when sliding the cool / warm slider all the way to the right, making the display more warm. Even though the issue is too much green, making the display warmer seems to fix it somehow. I know that the issue is green, because sliding down the green slider under advanced options fixes it, while sliding down the blue or red one just makes it worse
And pro tip, you can combine the cool / warm slider with the advanced options RGB sliders, if the warm / cool slider isn't enough on its own. Perfect mix for me is the cool / warm slider all the way to the right, and green slider decreased by 1-2. You could fix a bright red display with the combination of the general slider and the RGB sliders
I'm still concerned that Samsung isn't taking this time to educate people of OLED calibration. They could put this entire thing to bed with just providing more than 2 marketing crafted sentences. Not one thing is wrong with the screen sans those with actual manufacturing issues of course. Microsoft takes their pixel sense displays, like apple and individually calibrates them. Its why you don't complain about color on iPhones and even surface PCs.
This has 0 to do with the display, the manufacturing process etc. It's just a step that Samsung and many other don't do to their phones. They take a lot # for screens produced, get them close to accurate, preprogram the variables for the entire lot and off ya go. The update is fine because all it does is give yu extended granular control over the calibrations. Once you set the point on all, you'll be fine.
Keep in mind that even if they were individually SRGB calibrated for perfect color space and white point, someone who find them to look off because as humans our perception of color varies tremendously. I hate overblown colors yet RGB 100% dead on is weak and dead to me.
Just use your settings to make your screen right for you. That's all. Don't yell at CS, don't sit in the store waiting for their next lot of phones. They will be variations of the same display with slightly more detailed calibrations. And you'll have wasted time waiting for something you can just do yourself with some patience and correct lighting.
Funny thing about red screen and pink tint. I have my s8 plus since a week. My device came with lots of red tint, then I got an update that really helped, but still wasn't perfect. After few days my screen lost pink/red tint without adjusting anything. Of course, little pink tint on the edges exist but it's due to screen specifics.

What your saying makes a lot of sense to me, maybe you can point me in the right direction here. I have the S8+ with a pink tinted screen and even pinker edges. Fortunately mine is consistent across the screen. I have 4 other Samsung phones and the Tab S 10.5, which all have great displays (at least to me they're all great). Every one has a slightly different white balance, but they're all nice. They also can be tilted at very strong angles and only have very minor tinting of the colors. Now, my S8+ has been updated and I've been able to get the edges to look great. I'm also able to get the main screen to a really nice white. Here's the two problems I'm running into that you might be able to help me learn how to fix and finish getting my phone to the quality I've grown to love with all of my other Samsung devices. If i adjust my whites in any giving environment, say inside, it looks wonderful, but as soon as I go elsewhere, like outside, or go from incandescent light to florescent, the whites will go to either redish again, or to a green/blueish. I've never had this on any of my other Samsung devices, I mean they do change from warm to cool depending on the environment I'm using them in, but they never look redish, or green/blueish like my S8+ does, they are warm or cool. That's what I'm trying to adjust my S8+ to do. I have all the great new tools that Samsung gave us in the latest update, but for some reason, I can't get it anywhere close to my other devices and have it stay that way when changing the lighting I'm in. The second problem I'm having is that if my phone isn't held almost perfectly straight on, it takes on a pink hue again. None of my other devices do this either. Like I said, all of my Samsung devices have different white balances, but they're still enjoyable to use. The main reason I've stayed strictly with Samsung is their displays, I'm a huge fan and just can't find any displays I enjoy more than Samsung's.....until now. If you can share any advice on anything I might be able to do to fix my S8+, I'd greatly appreciate it, this phone is the best one I've ever had, and I really don't want to have to return it and risk getting a dud. The display is really important to me and if i can get it to be at least as good as the worst of my other Samsung devices, it would be awesome! Thanks in advance for any advice!

Now that seems like it might actually be a dud. Or try first calibration outside. This seems silly but are you using auto bright and adaptive display?

Ok, I will definitely try the calibration outside. I'm not sure I've tried it outside on a bright day yet. I am using the adaptive display setting and auto brightness, all of the other modes are quite pink and unusable, actually the tint is more of a magenta. I'm fairly certain its the adaptive display mode shifting my white balance in the various environments. Hopefully Samsung will somehow fix the other modes as well. The more I use my phone, the more I realize the biggest problem is the color shift that happens at angles. Almost any movement up, down, left, or right will produce a pink tint. If i go to an even stronger angle (around 75 degrees)the tint goes away. I can also get rid of it by turning both the red and blue down all the way and set the slider fully towards cool. The pink is gone when I do this, but then everything's really blue/green. Thanks for the suggestion, I'll definitely give it a try and let you know how it works.
I've tried calibrating my display outdoors, but the pink persists. I decided to send mine back to Samsung. They said they'll repair it lol. I'll just keep sending it in until it's right. I'm at Best Buy now to have Samsung flash my firmware like the factory asked, although it's not going to fix anything. I've looked at about ten various S8 phones on display and found only 2 with the problem, one of the was borderline ok, the other was just like mine. It's my first time seeing another S8, one that doesn't have the pink tint and it pretty much about took my breath away! The display was more beautiful than I had thought it would be. I just wish Samsung would simply make this right and swap out these faulty phones, heck I'd respect them for it. Having to jump through hoops on a brand new thousand dollar phone is ridiculous. I had debated about sending it in to Samsung, wondering if I was just being too picky. After seeing what the display is supposed to look like, there's no doubt in my mind that my display/phone/software, whatever, is defective. Grrrrrr
I received an update today and it has fixed my pink/red screen.

There is no chance I'd allow Samsung to "repair" my phone. This thing is brand new. You make them get you a BRAND NEW device out of a box you open in wherever you purchased it. Then you move forward in the store and check that display and all other fun things. Once satisfied, buy that unit. Why ever take a repair on something less than 1 month old. Have fun selling my OG unit as a refurb Sammy!
