Screen Hue/contrast or general background colour - MDA III, XDA III, PDA2k, 9090 General

I recently acquired a 2nd user MDAIII and it is in excellent condition, very happy with the unit. But something that I have noticed is the main background screen appears to have more of a yellow hue than that of my previous units which where white. For example if I place my MDA1000 and MDAIII side by side the whites in the MDA1000 are more prominent and crisp. Is this a normal characteristic of the BA type units. It also has a screen protector attached, could this hue be attributed to the screen protector?
In fact the hue is very similar to the background colour of the XDA developers website.
Thanks john.

screen hue/colour
Come on Guys all you BA owners must have some feedback to this? would appreciate it...thanks
John

spooky this post as just got me new m2000 today and was thinking my eyes where playing up.
deffo a yello tint to mine as well previous units didnt have this was thinking about asking them to change it

Screen hue
Thanks thought it was just my eyes, but there you go. Another one out there. I was informed that HTC sources the screen from different manufacturers so this may explain the difference. Alas I cannot take mine back. Other than that it functions perfectly. so no problems there. But may trade it in for a XDAIIi or equivalent.

M2000 with blue tint
I've just got a replacement M2000 which has a really strong blue tint.
If they are going to use different manufacturers for screens, i'd expect some tool to adjust the colour settings.

Yes I agree you can only alter the brightness of the backlight, but not contrast or colour. It would be a good addition. If they want to use different manufacturers then they should at least ensure all the screens are within a specified tolerance. Anyone else have any thoughts on this or how to correct tones etc.

Orange have agreed to replace my M2000. Aparently there is no software solution to the problem...

HTC Desire with pinkish AMOLED display anyone?

Hello. Received my HTC Desire today (typing this post on this lovely device)
Unfortunately, I'm noticing a subtle pinkish display instead of white and wondering if anyone else is experiencing this?
This is my first AMOLED display and wondering if this is normal or have I got a faulty display and should get it replaced?
sounds like a faulty display, as you can see on many videos on youtube none of them are pinkish
if you have another camera (or phone with cam) try to take a pic of it and post it. ... it does sound strange never heard anyone complain about the display
The only pinkish thing on my phone is background in Google Mail app. But that's how it's supposed to be I guess.
If the screen brightness is turned to a minimum, there is a certainly visible pinkish tint to the screen. This isn't bothering me though as I don't ever plan to reduce the backlight to that level!

I think that pinkishness (now that's a word!) comes from overall theme colors. If you turn it down to the minimum and visit a while page on your browser it won't look pinkish. At least it doesn't to me.
Thanks everyone. Tried the suggestions and here's what happened.
If I turn down the brightness, the subtle pinkish display becomes very pinkish, definitely exaggerates the pink hue effect ...
If I turn up the brightness to full, the pinkish display disappears.
Here's the funny thing ... Google Mail definitely has a slight pink hue, regardless of what the brightness level is but in all other apps, it doesn't ...
So, fellow xda'ers ... should I replace it or not ...? I wish I could say the subtle pink hue doesn't bother me, but I can't help notice it in Google Mail (which also happens to be my number one, most used application).
Really, I need to know whether this is a fault (or the start of this display becoming 'more' faulty) or just something that AMOLED displays generally exhibit ...
Your thoughts are much appreciated, as always ...

I would still recommend you take a pic of the screen in "normal" brightness and post it, .. that way every one can see and compare it to their own device (preferably use stock wallpaper).
This happens on the Nexus One too. There is nothing to be concerned about.

Hi, will try to take a photo ... I'm out and about at the mo, but will be home later tonight ... Will use my HTC HD2 to take the photo and post it up ...
Think hue you see is probably due to a characteristic of the amoled used in the Desire (and Nexus One). Have a read here.
I get this too I just assumed it was due to the AMOLED screen.

No i think his issue is something different, .. as he is noticing it on the pictures also not only text, ... (text is mostly effected because usually the black and white intersects, thast where the problem appears). however in the pictures, there should not be a problem (unless if this picture is black/white ofcourse)
I have this too, and I have two Desires - it only appears on one of them, so not all machines are the same. See my post new post from this morning.

can anyone of you please post a pic, ... i would really like to know how serious it is
It's NOT serious. In fact you could say the pinkish one is slightly warmer (which many people prefer), leaving the other machine looking slightly blue and colder.
Unless the machines are side by side, you'd never notice. There is probably more difference between your desktop computer and your laptop.
i have a zune hd and that is amoled and there is not even a slight hint of pink, so this is not something to do with amoled as a technology in general.
Figured I'd post this, clearly pink hue in comparison to the iphone. However this is one of the only videos I've noticed it in
Hmm, cant post links as I'm new,
youtube.com/watch?v=Tbb1b3AXOGs
Yes, just wanted to post that one. I found another one.
Funny thing is that some devices have that effect, some of them hoesn 't (or effect is not visibile on video).

Screen tint

The screen on my 8.4in Tab S is bugging me, is it just me?
With all "super enhanced" colour settings set to plain and boring colour, I keep noticing a slight green tint in the central area of screen when viewed square-on, it's very subtle and seems more obvious with text on the screen, e.g. the Tapatalk forum listings. Also when viewed from an angle the display takes on a slight blue tint, despite reviews saying how good the angles are, it seems worse than the LG G Pad.
Is this just a feature of AMOLED displays or could it be a faulty unit (how?)?
I don't see it. Sorry.

There shouldn't be any differences viewed at any angle with this screen. Try this... in bright sunlight, with the screen off, look at the screen on an angle. It should look a uniform color - actually almost exactly matching the titanium bronze bezel... just to make sure there is no physical defect.
Something to note - if the screen is OK, it could be your eyes (not joking). The eyes can play many tricks - for example, seeing a lightly shaded box with text on a piece of paper that is only black and white - the box can appear to be shaded slightly red. That's one example, but there are many. And with the resolution and technology of this screen, there are no imperfections to draw your attention, like staircasing, blur, backlight irregularities, that you are used to seeing. It is a bit confusing to our physiology, and our brain does this thing called "patternization" that can contribute to us truly seeing something other than it is. This seems to be more subtle, yet more frustrating on a display that is so close to perfect.
I'm not saying that there is something with your eyes specifically. It could certainly be a defective screen. One way to find out would be to take a look at someone else's - also, if you have another decent camera, you can take a picture of the screen and look at the picture - that will usually confirm (or not) whether what you are seeing is there. Like I said, it's not you or your eyes I'm dissing. These are things I've picked up on over the years. In fact, it could ONLY be my eyes. If that's the case, I'd probably rather not know.
You can also use a colorimeter and software like HFCR to get the discreet measurements from different parts of the screen. When I have done this, I've found that there was no real difference in chromacity. Of course, that has always made me walk away thinking that the colorimeter must not be accurate. So human.
I would definitely be interested in your feedback about what you find because I've obsessed over high resolution displays trying to figure out what is real and what I'm imagining... it's an active area of interest for me.

Yes I have also noticed this. I've seen these green or pink tints on all the amoled devices I've owned. You need pretty good eyesight to be able to notice it. You shouldn't be bothered by it, they're all like that, if you can see it. But you'll get used to it.
I probably will not get used to it...

Thanks Freshman206 and SrAdama, glad (?) to hear that it's not just me, I've had the tablet just over a week and still notice it. Any slight tilt and the colours appear/shift, green, pink and when angled beyond what I'd consider normal, blue.
Have photographed it and will have another go at getting it clearer but by winding up saturation the effect becomes visible in the photos (on pc).
I'm now trying to decide what to do about it, I have an LG G Pad which doesn't annoy in this way, though it has just gone away for a warranty screen repair for bright spots (not stuck pixels)!

It is probably the antiglare coating you are seeing.. If you have the coating on your glasses and check them out, it will do the same thing as your tablet... I also noticed it appears to have a anti fingerprint coating on as well, very nice indeed :>
In shops I also have compared 3 different Tab S.
All had an immediately visible green tint, white looks not white but greenish and a bit "washed out".
I find it a bit surprising that with other devices, when they have a tint (like the yellow tint of the Xperia Tablet Z), people complain much, while here, with this really apparent tint, people tend to say: It's normal, get used to it...
I would never buy a Tab S, just because of this tint and because of the, compared to other devices, low maximal brightness.
These devices are overrated.
I ran a poll in this forum as to whether people were satisfied with white reproduction on their tablets or not. Out of 15 responses 12 were satisfied.
We have heard reports of manufacturing defects such as yellows screens, muddy splotches in the middle of screens, loose creeky backs, warped backs and excessive lag/stutter.
These are not "normal" for this tablet but represent what may be a bad run of tablets that made it out of the barn. If you are experiencing the issues suffered by the OP, I suggest you seek a replacement unit. If you have observed similar performance from other tabs in the same store that would make sense as they are likely from the same faulty production run.
When operating normally, white should be white on the Tab S. For myself and the large majority in the poll, this is the case. I have also not read any reviews by professionals mentioning this discoloration and believe me, if CNET or THEVERGE had something to rag on the Tab S about they would have.

The average rating by actual owners of the Tab S 10.5 bronze at BestBuy is 4.8 out of 5 stars with 53 reviews.
The average rating by actual owners of the Tab S 10.5 white at BestBuy is 4.9 out of 5 stars with 36 reviews.
You will see very little if any mention of an issue with yellow or green discoloration. I'm sure you are seeing what you are seeing but the problem does not appear widespread.

I just took a picture of a webpage with a white background on my 10.5 and sent it to my laptop which has software that measures colors.
The website background from my Tab S 10.5 measured at 255:255:255. That is pure white. This was a photo and not merely a screen shot.
Saw the 10.5 inch and 8.4 inch models together on display in a shop. The 8.4 inch version also had slightly yellow tinted whites when looked at directly, not as bad as I was expecting though. The 10.5 inch model had no yellow tinted whites at all, when looked at directly or tilted.
Mine has pinkish tint at the top visible when everything is white especialy when reading wikipedia

so when i switch screen mode to amoled basic, my screen have yellow tint (like warm color) and a little washed out color, is it normal or just my unit?
because when i switch screen mode to amoled cinema, everything looks saturated which is i think okay...

Yes the Basic profile is meant to be that way its not the screen problem being discussed here, if you wanted an accurate image then Basic is the closest of all the profiles. If Basic looks washed out to you then your used to looking at an oversaturate screen, if you were used to looking at calibrated screens then all three profiles would look over saturated.
I had the 8.4 and just returned it. I also had the greenish-blue tint when the screen was even just slightly tilted. More noticeable indoors with brightness set to below 40%. If I had the tablet flat on the table and walked across the room, I could see it too - screen only looked good if looking at it directly in front of you. As others have said, I think it's probably due to some coating on the screen, which explains why it would be more noticeable with the screen brightness set lower.
I've checked out a few display models at stores, they all basically look the same, though some were slightly worse than others. That being said, the 10.5" ones I saw don't seem to have this problem... if they do, it's definitely not as noticeable. Not sure if it's just an optical illusion or what, but the 10.5's look OK. I'm going to go buy the 10.5 one today, mainly for the size. I'll post again if there are any tints on the screen.

The problem was a green tint in the center when looked at head on not at an angle, seeing shifts in color when tilted is normal for this tablet. I would have kept yours if it was fine straight on.
My 10.5 had greenish yellow tint when looked at head on exactly the same as the op.

I was gonna return for the 10.5" anyways, the screen tint wasn't part of that decision, but I certainly won't miss it, heh.
Mine it is extremelly yellow! I hate this bug... It happends to me every 10 minutes, i need to restart every time to revert this.

A very bad display

Ever since I got my Xperia M the display has had blueish tint and bad color reproduction but I acknowledged that is a problem with every Xperia M. But beside that, when I look at the display from an angle, on a white background, I can see a gray line appearing from top of the screen and a gray circle in the middle. Again, it is visible as an effect when looking at an angle, cannot see it when looking directly at it. I also have a bright pixel on a black background. Are these also negligible, common issues or along already bad screen I've got a defected screen? I am very disappointed in Sony anyhow.

I'm pretty sure I saw this post somewhere b4... anyway for bluish tint - get the white balance app from @xperiaz2 (Yes, you need root and the bluish tint is due to the colour temperature, its at around 10k+, the norm. being around 6500k) Gray line appearing... pretty sure you're having a defected display and about the bright pixel, display is defected. Yes you got a defected screen (The bluish tint is not a defect though) so just bring it back to where you bought it and they'll replace it for you! (If the warranty is still live)
Well I posted on Xperia support forum trying to get help there, too. Or just an insight of what could that be and what could cause the problem. Anyway, here are a couple of pictures taken with a phone. The camera couldn't get that grey line properly but it appeared as a shadow from the top of the screen probably because as I said it's like an effect when tilting the phone, not a still colour. http://imgur.com/3Ae2rdr http://imgur.com/Nyv2maS
I suggest you to bring it back to the shop, that problem isn't present on mine.

Display color

HI, my display is darker on the right side if I put a gray color in fullscreen with low brightness. I'm using swift dark substratum. OnePlus told me that it is a defect of all amoled. Does it happen to you too? sorry for my English. See attachments. Thank you.
Mine is noticably darker in the lower part of the screen. I've read tons of reviews and stopped worrying about it -- the AMOLED displays can't show consistent color by nature.
I had this problem on my OP3 but I left it too long thinking I'd get used to it so I couldn't return for a refund or exchange. Don't leave it too long and get yourself a refund or exchange if possible. That's cleary a defective screen.
Fortunately my new 5T is so much better. And is pretty even with the screen uniformity.
I have this issue but only at certain brightness levels, fortunately it's very minor to the point where I can't notice it unless I'm actively looking for it
I've had 4. All the same uneven tints. But but different from left from right which is off putting when reading or looking at content with white or grey backgrounds. Sending it back trying something else

Just got my S9, but why the screen tend to be more yellow ?

Honesly, i don't expect the screen to be yellowish like that, but it is a bit yellowish only if i view it 90 degrees directly. If i view it from the side, the screen shift to blueish colour
Your guide is so useful since i am a new Samsung user, thanks
What phone are you coming from and what other electronic screens do you have around? The S9 is calibrated to 65K (see color temperature) and can appear yellowish if you are used to other screens that defaults to higher color temperature (including most iPhones/iPads). In that scenario there is nothing wrong with the screen and your eyes will get used to the new white pretty quickly.
On the other hand if your screen appears severely yellow compared to other Galaxy S9s' (e.g. check store models) then you probably should 1) get yours replaced from where you bought it, or 2) contact Samsung tech support.
Thanks for your reply, i come from Xiaomi Mi4i, it is cheaper phone by a large margin, but i don't know why the white seems nicer. Oh and i have another question , when i tilt the screen to the side, the white switch to blueish colour and it seems nicer than staring at the phone on 90 degrees, is that sAMOLED thingies ?
As to your latter question, yes that is an AMOLED thing. As to the first, do this simple test: Go to a room with no direct sunlight and no other electronical screens, where you can just look at the phone's screen without distraction. Use the phone for 10 minutes or so @50%+ brightness as you normally would, without worrying about 90 degree tilting. Do your eyes see the whie as yellow? Or have your eye adjusted to the new screen and white now looks white? If the latter, then your screen is likely just fine.
If you want to see what yellow-white looks like, try "Blue Light Filter." That thing does turn the screen yellow. (maybe you have it enabled now and that is why you are seeing yellow? )
---------- Post added at 03:00 AM ---------- Previous post was at 02:38 AM ----------
I have no first-hand experience with the Mi4i, but judging from what I can see in videos its color temperature is at least at 7500K, meaning it has blue-ish white.
https://youtu.be/RxymBx8rjos?t=68
hi im having the same problem with my s9 brought it yesterday and youtube videos look horrible discolor yellowish
had that issue with my first S8+. compare it with store models to check. my replacement was much better. now I have the S9, and it's definitely not yellowish. it's such a good white balance actually. so if you're not happy with it, exchange it while you can.
Thanks for all of the reply appreciate it, i check to the store and... turns out it is the same white as mine, still like the bluish white on my former phone. Compared to the note series, the note has better white. I tried to change the screen settings to cool, but it appear greenish. @lopri Thanks for the research on Youtube, respect for the additional research
I already calibrate the screen to cool, to overcome the greenish, i turn down the red and green color, now it is better but still can't resist my old phone blue-ish white.
When watching video on youtube it turns orange-ish, it might be because the video enhancer <- Now this is the problem
Before i got the phone, i have an impression that it would have a very great display... , but now it feels -- only good, but not overwhelmingly great like the review said
"ยท Record small Shifts in Brightness and Color with Viewing Angle, including White."
http://www.displaymate.com/Galaxy_S9_ShootOut_1s.htm
Adjust the display settings. Put display warmth to the highest then reduce red and green to a quarter.

it's possible the store display also has the same issue. mine is bluish white. I went through the same thing as you with my former S8+, in that even changing settings to cool, didn't make much difference. the replacement I got after confirmed that it was the display itself.
Yep, comparing the S9 and S8 side by side the S9 has a yellow tinted screen. The whites aren't as clear even after adjusting the colour settings.
