[Q] Yellow Tint & Brightness issues (again!) - Why??

I know there are other threads that discuss this topic (somewhat) but I wanted to post this separately because what I'm asking is very specific.
I've had about 8 separate Nexus devices from Google Play in the UK and every one of them has had the same issue:
The display has had a noticeably yellow but admittedly slight (possibly slightly brighter) tint on the bottom and left edges, while the right edge has been dull/dark.
This is specific because there are other and numerous reports of a yellow "tint" across the whole screen. This is not the whole screen, this is very clearly just the bottom third and left edge of the screen.
Some think that this is a "glue" issue that will resolve itself. Some think it won't get better. Some think that it's an issue they can live with. Some can't stand the lack of uniformity.
Well I can't stand the lack of uniformity because in my opinion, on a 4.7 inch screen, I find it distracting to be reading text on a solid background or white and the "white" or background colour changes as I read right to left or top to bottom. I consider a decent amount of uniformity to be a minimum requirement for devices which will be used in the way most of us use our phones and tablets. Manufacturers, seemingly, don't care at all except in the most extreme of cases. It looks like they are churning out whatever they can get away with. In all other aspects, the N4's screen is fantastic.
There's nothing anyone here can really do to help directly but it leads me to a question I haven't been able to find the answer to anywhere by Googling or searching other forums:
What is the cause of this lack of uniformity on these LCD panels? It seems to be LCD specific. As mentioned, some think it's "glue" but then others say not and in my experience the tint issues haven't gotten any better in the time I've had the devices that have passed through my hands.
I don't think it's the LED backlighting but could it be something to do with that?
Does anyone know, from a technical point of view why LCD panels are so prone to this issue with the yellow tints across *part* of the display. It's a very widespread thing as it's been noted on most of the iPhone range and a lot of other handsets too. Is there something inherently difficult for panel manufacturers (in the N4's case, LG) to do to make the panel evenly toned and lit? Surely it can't be that hard at this stage in the development of LCD tech once the manufacturing process is "calibrated" at the factory and underway? I assume these handsets are assembled by robots, not by hand. Is that right? Why is it so widespread? Is it a cost issue? Would I have a better chance of a quality panel by buying a more expensive handset? (Although I've seen many HTC One X's with the same problem - I did see one which was almost literally "perfect" in uniformity and brightness). I'd really appreciate any feedback on this. I know that because it's the "norm", sadly, the common response is to now "accept" the panels and handsets that are out there. There doesn't even seem to be a "higher end" manufacturer where high quality uniformity is more likely - or is there?
Anyone with a good/strong knowledge of LCD tech or the manufacturing process out there that can explain this?
Thanks!
***UPDATE***
I've now attached an illustration to show what I mean. ***It's exaggerated a bit*** to show the effect but illustrates the problem clearly.

Have you tried using a custom kernel to tweak the colors of the screen? The Nexus 4 is known for it's washed out colors so using a custom kernel like Trinity or Franco kernel allows you to tweak the color of the screen to your desire. Of course you will need an application to tweak the colors.

LG is known for light bleeding and or panel uniformity issues, I had to swap 4 LG tvs before I decided to go with Panasonic , my LG ips monitor that im typing on right now for my pc has light bleeding in some areas which results in low contrast. I saw about 13 different optimus g devices before I got the nexus 4 and the screens are beautiful with good contrast, punchy colors and good black levels with no light bleeding or weird tints while my nexus 4 has slight light bleeding right where the signal bar is located. I love this phone and its seems to get the " perfect " one you maybe have to swap a few times and to me the price kind of fits the quality of the phone but then I almost have enough spare cash to buy another one lol can't complain about that.

Thanks for the reply. I've heard elsewhere that LG specifically seems to have poor quality panel uniformity. I think LG panels are used by Apple who have had many, many reports of panel yellow "tint" issues on both their iPhone and iMac range. It seems to affect screens big or small. Having said that, HTC had similar problems and their panels were manufactured by Sony. I would *love* to know what's causing this or what is the reason for the yellow "tint" issue on part of the screen.

I have done all of that and with some success with all of the handsets I've had but because the tint affects only part of the screen in a sort of gradient - the calibration cannot fix it.
I'd much prefer a screen that had a yellow "tint" evenly across the whole screen then of course I could calibrate accordingly.

You've had 8 different Nexus 4's?

yellow patches is from the glue used in the optical lamination process, yellow tint is from the display calibration which is often used to reduce banding and gives more saturated/warm look to colors
if your device is affected by by visible yellow patches the only cure is to re-calibrate the display to reduce the effect and don't get the device too hot as it may increase it

Sorry but this is not what my OP is about. I do not have a uniform tint and therefore it cannot be to do with "calibration" of some sort unless I am mistaken. Neither do I have "patches" or "spots". This is very specifically about a gradient yellow "tint" that only affects part of the screen and trying to find out the technical reason(s) for its prevalence in a wide range of LCD screens used in mobile phones and of course the Nexus 4 in particular. I've updated my original post to include an illustration of the effect I'm asking about. Thanks!

I am pretty sure its a hardware fault and i assumed you tried to return it otherwise there is nothing else you can do so i suggested calibration to reduce the effect

I had the same issue, then flashed custom ROM and it was fixed. Go figure :silly:

How to check what screen you have

Hey everybody. My 32GB Prime arrived yesterday and I'm a little underwhelmed by the screen quality. Compared to my little Jiayu G4S the screen doesn't look great, especially white. Thanks to lolo9393 I was able to read through the thread below and on about the second page there is info about how to discover who made your screen. Even though Xiaomi claimed the screen would be made by Sharp, it looks as though this is not the case for some of us. To test which version you have, open the dialer and enter *#*#6484#*#*. This will open a test app. Tap 'software version' then scroll down to where it says 'LCM'. It would appear mine is made by Tianma which explains a lot.
For those of you who haven't bought your phone yet, I would recommend asking your reseller to test your device first and see which LCD had been used. It sounds like AUO make a better looking panel (edit - or not?)
Here's how my Tianma screened Prime looks next to an Oppo Find 7a. Both are set to Max brightness. The Note 2 display is set to 'cool' in settings which is as blue as it gets. Any of the other settings make it look more yellow. The Oppo is on the left. To the naked eye the Oppo doesn't have the pink tint that you see in the photo.
*update* I thought I'd take another photo of my screen after two weeks and three different ROMs. Now I'm using the most recent multi language development ROM from 11th September. Same scenario as before, both screens are set to maz brightness, Opposed find 7a on the left. The XRN2 is set to 'cool' in settings and reading mode is off. Looks a little bit whiter than before to my eyes, but perhaps that's just wishful thinking. Either way my cheapo Jiayu G4S looks better than both. Shame the GPS doesn't work on the Jiayu!
http://forum.frandroid.com/topic/225576-xiaomi-redmi-note-2-mt6795/

Same here, me and a friend checked it, and both we have the Tianma screen. Both phones are 16GB version.

That's annoying. On the one hand, I guess it's common for manufacturers to use parts from different suppliers, but the phone has to only just been launched and Xiaomi made a point of bragging about using a Sharp screen. I think it's dishonest. I don't think I can return the phone to the reseller because it's not really their fault. My Jiayu G4S was just as cheap and has a much nicer screen.

Uhh. Does it really look that bad? I have ordered a Redmi Note 2. Hope that its screen is manufactured by Sharp.

For what I paid for this device, I think the Tianma screen (yes, I checked) on my device is fine. I think of this as an intermediary device as I dropped my old phone and needed one ASAP and in August this was the best thing on the market, for me it is a great intro to Xiaomi and I will wait to see what the Mi5 reviews are like when it is launched.

Do you have the TDD, FDD or GSM version?
Thank you!

Does anyone found a SHARP one, or they are all Tianma???

Yeah, I'm wondering about the same thing. Which versions have Tianma screen - all 16GB (not Prime) versions, or just the GSM version? Or is it completely random?
In a Russian video review a guy said that he had yellow tint with the GSM version, and that the display is better on LTE version (I don't remember which one was it though).

I have the 32GB Prime LTE version, and it has the Tianma screen. It's not awful, and considering the SoC I guess it's where they've saved money. If I hadn't just owned two Chinese cheap phones with better screens, I wouldn't have been any the wiser.
If I had a way to contact Xiaomi directly I would ask them to replace the phone, purely on principle.
One benefit of this screen is that it is softer on the eyes at night if you're reading in bed.
I might not be able to do it for a day or so, but when I get a chance I will try to take a photo of the difference between devices to show you.
Again, it's not terrible by any means, it just didn't meet my expectations.

Okay, thank you for your reply.
However, in this screenshot it looks like the other way around.
http://attach.bbs.miui.com/forum/201509/08/213030ox1sde17j41jcbd4.jpg.thumb.jpg
Tianma screen is blueish, but definitely looks better than AUO. Or could it be just about the Color Temperature setting in MIUI?

To my eyes the 'standard' setting looks creamy/yellow and the the 'warm' setting looks very pink/yellow. I set it to 'cool' immediately and it looks kind of OK, but it lacks 'pop'. I you were to put it next to a 2013 Nexus 7 it wouldn't look very good at all. Maybe tomorrow evening I'll try to mirror my screen to the TV and take a photo of the difference.
Viewing angles are good by the way. There is some 'crush' in videos and on the home screen wallpaper for me. I think it really will depend in what you're used to as to whether you like it or not.

This's the "old" news in China's forum, NONE of the screen is provided by SHARP
All the provider are from Tianma(85%)/AUO(15%) the number is the chance you will get.
There's also the rumor in China that Xiaomi never claimed they will use SHARP/AUO in screen, but actually, some of the people found that there's some evidences shows there's a slogan on their official site before selling.
And some of the people said Xiaomi break the rule in China's market with its super low price to force all the mobile manufacturer to lower their price. So some of the manufacturer edit the picture and spread the rumor that Xiaomi cheated consumers.
This is still a mystery because Xiaomi never apologize to this event but make good a loss
to the consumers a 5000 mAh power bank if you buying from their official recognized online shop, Tmall.com and JD.com.
I think Redmi Note 2 is released in the short time that the engineer in Xiaomi did't even tune it completely. The first or second wave who get the phone complaining the tint is too yellow compare to others. But if you are worry about the yellow tint, you can OTA to the latest stable version of MIUI or by FlashTool.
Don't forget MediaTek have the new technology, MiraVision™ which can easily tune the tint of screen color. By the latest stable ROM(6.7.5.0 Stable), Xiaomi also fix the unresponsive touchpannel by upgrading the driver of CTP from T2.0 to T2.3.
In short, you'll never get any screen from Sharp but mostly from Tianma and likely from AUO.

I have both LG G4 and N2 16gb, the Tianma screen isn't all that bad, although I see some slight bleeding that the bottom, but I can live with it, it is my seconardy/gaming phone afterall

I just got the phone. It has Tianma screen, but it looks good.

I'm pleased you like it I guess it just depends what screen each of us is used to. Sadly I've just come from a very 'white' looking screen (not sure if that makes sense).
I also just tweaked things manually using the Miravision app to get it more to my liking.

The screen on my phone looks very good, don't care who is the manufacturer of it, but i just checked and it is Thianma. I even compared it to calibrated with custom kernel Nexus 6, and still looked good.

That's interesting. I wonder if some are better than others. If not I must have really weird eyes, although the difference with the other phones in my household is very pronounced.

I checked and also got a tianma screen. It doesn't look too bad. I compared it to the xperia z2 (which has a pretty average screen though I think) and it wasn't really any worse. Maybe very slightly more faded at max brightness.
I'm more concerned about how much battery this thing uses. I've only had the phone for a few days but it hasn't seemed that great. Although the automatic brightness sometimes feels erratic and made the screen too bright.
Also I think I got some scratch already on mine. It's not visible if I wipe the screen clean so just need to do that and apply the screen protector that came with the phone. But I suppose no gorilla glass here!

Sorry to hear you have a scratch already I better hurry up and buy a screen protector for it. So far I only have a gel case to cover the back.
I'm not getting great battery life either, but I've only had a few battery cycles so far. Perhaps it will improve. My little Jiayu G4S also had a very good battery life which may mean my expectations are set quite high.
I'm not sure, but I think my screen may actually be getting whiter over time. Perhaps I'm just getting used to it!

my screen is scratched on day 2 as well in my pants too. Definitely not Gorilla glass.

Fix uneven/yellow screen with intentional burn-in

So I was on my 2nd Nexus 6P and like the first it had an uneven screen. Normal/slightly pink at the top and at the bottom it's more yellow. Instead of returning it I've decided to try and fix the yellow tint by intentionally causing a burn-in on the over-enthusiastic green pixels in the bottom half of my screen.
To do this I flashed a kernel which unlocks the high-brightness mode of the display, the awesome EX kernel, set my screen timeout to 15 minutes and left the display turned on for 3x15 minutes in high brightness mode with a black-to-green gradient open full screen in the Photos app (absolutely nothing else on screen). After each of the 15 minutes I checked the progress, after the 3rd time I considered it done. I'm happy to report that this has nearly eliminated my uneven screen problem.
So far I've seen no ill effects, just a nice even screen.
I used this black-to-green gradient that was a close match to where my screen was yellow. My first 6P had a different pattern of yellowness, so that would have required a different gradient, more like black-green-black.

Interesting, the normal slightly pink at the top transitioning to yellow at the bottom describes the screen on my original nexus 6P and it's replacement.
I'll look into giving this a try as well.

I´m not sure if something like this could be considered as a defect. If you look at a very high angle, you might see some sort of "rainbow effect" on the screen. You should be careful about "burning in" Pixels in a Amoled screen. High brightness will wear out the LEDs faster than you think. At least this is how I remember my old Samsung Galaxy S3 but maybe Amoled technology has improved a lot.

I can't really comment on if the OP's method is safe or not, but it is worth noting that the gradient/tint change is noticeable even when viewed straight on under normal use, such as browsing etc.
It could sort of be likened to the old TN based flat screens from a number of years ago where the top and bottom looked slightly different colours, however a lot of this was down to narrow viewing angles. I'm wondering if the same applies to the specific AMOLED display used by the 6P as well.
The AMOLED screens on my Moto X 2nd Gen and Moto X Force don't have the same problem.

I have a slight purple tint too on the screen but it is only visible on a white background. It does not bother me, if you set a higher brightness it is barely visible. Maybe all Nexus 6P have this sort of display and you simply have to live with it.

Would you happen to have a before image for your screen? I would like to try this on my phone but can't say for sure what exact color the uneven section is. Most of the screen seems to have a pink tint that fades into a green/yellow tint in the bottom left corner. I don't want to stress the wrong color accidentally.

Can you post before and after pics of your screen please?

Its a well known characteristic of samsung AMOLED screens. Samsung users have been complaining about this for some time. Its actually worse on the sgs6. But more brightness will make it less noticeable. Honestly, if you forget about it and stop focusing on it, you will stop noticing it.

Yeah I understand some are really bad you should send it back.but if its slight. There's no.point obsessing about it. It takes the joy away from using the phone

It's impossible not obsessing about it since the display is very thing you look at when using a phone, people wouldnt tolerate if it was an LCD, dead pixels or any other defect at the advertised price, but since it's amoled we should be expected that these errors occur.
The issue on slight displays is that the screen is uneven on white, so its impossible to ignore on web browsing and how dark ui and gapps is not provided by Google, I would prefer it to be slightly pink/blue all over not half so you won't notice it.
Not meaning to rant and whine but consumers shouldn't have to accept this or fix the issue themselves, when I show the phone of friends, they notice the inconsistent white background and are shocked when I say its something you have to live with, the features are not going to outweigh the display issue
The joy of the phone is still there, just wish they implement quality control.

I complained about this on my Nexus 6. Ended up buying and returning a total of about 8 phones from various stores until i found the "perfect" one. Its incredibly irritating when you can notice it and its the first thing you see when the pixels light up. Some people may care more than others but im not willing to compromise anymore. AMOLED displays look great, but LCDs seem to have a better yield or QA. I was of course down voted and flamed about this. Good to see people starting to take action against garbage quality AMOLEDs.

This post is old but I wanted to try this nonetheless. You can't just burn in or wear out the pixels in such sort of time no matter what. 45 mis is not enough to cause such an effect. I tried it as I have a screen with the same exactly issue but there is no change. And I did it for far more than you. I let it all the night long for 3 days. There was no change. I don't think you can fix this issue this way (or any other way)

You guys keep saying "AMOLED issue". I bought 6p after having OnePlus X - it has AMOLED without any issue, it was perfect screen! Nexus 6p is great phone, but screen really bothers me... I hate, but I need to replace the phone. And I am not sure whether I will get a good phone or not. Support told me that if I would ask for replacement - they could send me a refurbished phone. Only buying new will give a new phone. I can still return it as I have it for few days...

Huge display color temperature difference in Demo units

So I went to the Samsung 837 experience store here in New York City and got a chance to play with the phones. Both S8 and S8+ are stunning. However I have observed a huge color temperature difference in the display panels of couple demo units here. They were running the same display settings. Please see the attached pic. Sorry for poor quality.
I personally love the whiter display and hate the yellowish tint on phone screens.

holy crap thats bad, the left one looks kinda broken, its too pinky

its a demo unit what do u expect ? i doubt retail phones will have that problem..

That's really bad. I remember some S6's had salmon pink displays.
Perhaps it's some kind of night shift feature, the devices may have had different time zones, etc.
We can only hope!
My Note 7 had the best AMOLED display of any device, PERIOD!

Guys don't worry there's options to change the color temperature. Maybe someone was messaging with it before.

This happen on the HTC One.
I had my phone and had no problems with it then got the pink camera problem.
Was sent another one that has the yellowing screen. Got a third one that was fine.
Most of the time its a bad lcd screen. And if you get one call who ever you got it from and tell them and they normally replace it easy

That is very shocking. The Note7 display was INCREDIBLE. I fully expect these to be even better. Hopefully it's as someone else mentioned... maybe they used poor grade panels for demo units on purpose? Or maybe someone changed another display related setting somewhere... either way, I don't care too much about the color temp as long as its a UNIFORM display.

EDIT to snip original content.
This is a potential problem... but hopefully not one we'll see either widespread or on retail units, as evidenced by Erica's overview here: https://youtu.be/rhoyPn2_O0M?t=7m30s

Yikes, thats an instant return for me!

They better not send me one with this defect I have been waiting for the S8 since the Note 7 problems!

Don't forget that you can change the color temps on the phones in the settings. As this is demo units, the chance is high that someone have been messing around in those options and changed the color temps on those phones.
Same goes for the so called 'burn-ins' on the Super AMOLED screens'. Most peoples are complaining that they see 'burn-ins' on the demo units in the stores. But that's because the screens are on all the time there and are being messed with all day long.
So for normal usage as how we users are using them, you wont experience 'burn-ins' on your phones with Super AMOLED screens. Or the chance of seeing it that way is extremely tiny or non-existant.

I was just about to say you can have night mode to help with darker rooms. That's what the other screen looks like.

Every phone with an Amoled display has some variances between devices, it is very minimal and you won't notice unless you look for it and you compare screens. It happens with LCDs sometimes too.

Two things....
First, why in the HELL is the time different on the two phones? Isnt it set by the carrier??? Did someone change it manually? lol
Anyways on to the important thing, whats the additional icon in the notification area? Its only on one of the units. Im curious if that would represent one of the night mode settings or something that could be on as suggested?

Lol, no idea about the time. I didn't notice that. The other icon you see is something they call Retail Demo mode or something like that. I was unable to disable that. However both the phones were running in this mode. I completely agree with the chance of someone messing up with the RGB values, I forgot to check that. However Erica's video shows that the displays can have different temperature even when there values are set the same. I am not loosing my sleep over this as I know that I can adjust the RGB and get the color temperature I want.

Two things....
First, why in the HELL is the time different on the two phones? Isnt it set by the carrier??? Did someone change it manually? lol
Anyways on to the important thing, whats the additional icon in the notification area? Its only on one of the units. Im curious if that would represent one of the night mode settings or something that could be on as suggested?

You are very observant lol I would have never noticed that

Don't forget that you can change the color temps on the phones in the settings. As this is demo units, the chance is high that someone have been messing around in those options and changed the color temps on those phones.
Same goes for the so called 'burn-ins' on the Super AMOLED screens'. Most peoples are complaining that they see 'burn-ins' on the demo units in the stores. But that's because the screens are on all the time there and are being messed with all day long.
So for normal usage as how we users are using them, you wont experience 'burn-ins' on your phones with Super AMOLED screens. Or the chance of seeing it that way is extremely tiny or non-existant.

You can only change the color temp when using Adaptive Display, and Erica clearly showed the RGB settings were equal and also tried different modes - that was not the issue.

I noticed the same thing while watching demo units at the Amsterdam airport. Some units had pinkish tint. Normally if you look straight at the screen it is not that visible, but then if you look from little angle the screen gets really pink. Besides that one unit had visible pink on the edges of the screen (at the top), even if you looked straight at it. It was definitely not the software issue as all phones had the same display settings. I'm really concerned right now. Out of four S8+ half had this issue and for S8 only one.

A few display questions

Hi @all
is it normal to have a perfectly white display when looking straight at it and to have a slight reddish veil while tilting it? And is it normal that Amoled Cinema and Amoled Photo Mode are a lot more reddish than adaptive mode?
I am on my third Galaxy S8 now. My first one had a perfect display, even when tilting it had the standard blueish color of the Amoled Displays. Had to send it back because of a hardware issue.
My second and third one have the above mentioned "problems".
How is it on your device? I'm already thinking of returning even this one... i want a perfect display for the price I am paying.
Thanks for your reply.

I don't see any redish tint when tilting. Did you update your phone with the fix?

Yes I updated the phone to the latest firmware.

@Duskfall89 mine has that red veil issue as well but not enough to make me go nuts. I once had 1+1 and yellow band issue drove me nuts. Nevertheless, i think you can just set the red to the lowest on the RGB settings and it will go away. Im more worried about the battery haha

It's not an issue of being standard on oled displays. The blue tint is to produce a "vivid" look that catches the eye better.
Cinema and photo are suppose to have a warmer tint to match real life viewing. (because in real life, things have a warm tint) from the sun, and standard lighting.

It doesn't make me go nuts either but I know how perfect the display of my first S8 was

So is it normal that cinema and photo mode are more "reddish" than standard adaptive mode? I never tried those modes on my old S7 so I don't have any comparison.

@Duskfall89 i know how you feel. i can also verify that mine has a red veil when switching from cinema/photo/adaptive. Regardless, i think i can live with it. After going through the forums, many s8s are plagued with this issue and i got mine on Monday mind you! Others have mentioned that they have swapped around 3-4 units with most experiencing similar redness. If you're not satisfied, there are also who have swapped till they got the least red display unit but that would also run the risk having other parts that come faulty.. alas, people are never satisfied. I once swapped 3 msoft surfaces.

Yes, it's a lottery I guess...
I think I will stick with it, it really doesn't bother me too much, it's more about the fact that i know how my first S8 looked.
Amazon won't replace it anymore because it's the third phone I'd send back and so they want to check their entire stock. They offered me a complete cashback if I return it but then I would be without a phone. I could give it back, take my cash and then buy another one (which is now much cheaper than the price I paid at launch) but I am tired of setting up phones now

Yessir. They use a warm base as opposed to a cool base. If you really want to learn more about it Google TV color calibration and it will go into detail about why they use a "cool" blue tint for floor and selling and how true natural colors are more "warm" reddish
Then I recommend calibrating your TV and after a day of adjusting, you'll never want to go back.
Also, blue filter in the Phone settings will add a warm tint at night to help your eyes

@Acoustichayes good info !!! i guess i wont be so worried! but i guess the only issues here is that my reddish areas are focused at the top of the display and is not uniform across.

Thank yah. And the red tint on the top was apparently a software issue that was fixed in an update. There's a thread on it here somewhere. Just make sure your phone is updated

I had the same case but cannot really consider it as an issue as sometimes, i cannot barely see it. It's just the way it is. Also, you might wanna check out wider color gamut. i think that we're just used to the "blueish" as it looks natural but samsung uses deep red this time.

Hi, what do you mean with "had" the same case? did you get rid of it?
I got used to it now and it really isn't an issue but I'd prefer the "blueish" tint as my first S8 had that. Sadly it had the home button bug so I returned it.

Ok then it's the same as mine I could be make it more white if I'd play around with the colors but even then, while tilting the reddish veil still remains. Less noticeable but it's still there. So I decided to leave it as it was out of the box. At leats my home button now seems to work properly :laugh::laugh:
