White saturation (contrast) is driving me nuts !!!

Like all of you I've used a lot of lcd devices in my life....but this one definitely has the worst white saturation I have ever seen! I'm surprised nobody hasn't mentioned this before.
Can you guys please tell me that my device is damaged or something...
You check your screen by looking at this picture http://www.lagom.nl/lcd-test/white.php
Ideally you should be able distinguish between all of the shades of grey and the white background.
I can only distinguish 200 (which is pretty obvious) and *barely* the next three ( 244-246). Everything above 246 I cannot see.
Do you guys know any settings that can be change to improve this ?
My current solution is to use Screen fliter app which makes the screen 10x better to look at but I it darkens it a lot.
Btw I'm on official .29 with root.

Gets hard for me to decipher at 250.

250 I can see, anything after that becomes near impossible.

Thanks guys for your replies.
I just went back to the store and compared my tf300t to the demo unit. My unit is clearly faulty ... my screen seems to be brighter but the contrast is worse. On the demo unit I could also see up to 250. So we can assume these are the correct values for this display.
I will get my replacement unit as soon they have it in stock
I'm so relieved...

I got to 249 on my tablet, and to 254 on my calibrated IPS panel on my desktop (just for reference).
Not too bad for a tablet screen imho, also glad you got a replacement.

254 on my phone, which is known to not have the best screen in the world.
250 on the tablet, which is kind of depressing...

250 is barely noticeable here, anything past it is just white on mine.
My SGS AMOLED+ goes to 253, just as reference.

Yeah same, mine goes to about 250, but I can say that I have noticed a little over-saturation but not often enough to be a problem or deal breaker to me.

Differences in screen colours/brightness

Hello.
I have a Nexus 4, as does two of my friends. I got mine in February, as did one of my friends, the other got his last month.
I compared my Nexus 4 with the other February Nexus 4. His screen seemed brighter than mine, but it also had a slight yellow tinge to it, whereas mine was more dull/blue. This was the same with the other Nexus 4.
Is there a problem with my screen or is this just a common difference between all phones?

Franco Kernel perhaps, that has color profiles that will change the colours and look of the screen.

So it's just the calibration, not a problem with my N4? Even though the others seem slightly brighter?

Same staff
I have the same problem. The screen of my N4 has different colors than the screen of my wife's N4. Purchase difference - 2 months. No root, display settings are identical. Can't figure out why?

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!

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.

Yellow Display

hello all,
yesterday i got my 6P. next to my XPERIA Z3C its very yellow. okay on this photo it looks extreme in reality its not so extreme. i write an email to the seller and they told me they know this problem and it will go away after about 1 week. can anyone confirm this?
** sorry for my bad english
greetings, denis

If you select use sRGB in the developers options, it should fix it.

i already tried that but it turns always off on reboot. and i think normally it should work without using the sRGB function...

I'm not really sure then. I don't really notice it on mine if it is yellow.

I understand your frustration. I have a 6p and also a Z3 and when I first compared them the difference was obvious.
The problem is that that'll happen whenever you compare an LCD screen with an AMOLED screen, LCD will always have "whiter whites". The degree will vary depending on the model though.
Anyway, if I didn't also use my Z3 then I'm sure after a few days my eyes would've gotten used to the color calibration, but since I do use it, it was driving me absolutely crazy.
After some research I saw that the best solution to my problem was to install a custom kernel. It's a fairly easy process and there are several very stable kernels out there for the 6p. And with that you can tweak the screen color calibration. After this, I couldn't be happier, my whites actually look white and not yellowish

At least yours is uniform. I'm on my 2nd 6P and this one has uneven tint with the lower screen being yellow tinted and the upper seems normal and warm. Returned my first due to other issues.

I doubt it will go away within a week as the problem lies with the screen calibration... What i did was flash elementalx kernel and calibrated the screen. Now its much better.... Not as white as compared to my OPPO find 7 but way better then initial color...

This. I'm on muy eighth 6P because they've all had uneven yellow tinting to the display. I've gotten to a point now where I've realised that they're all going to have this problem, and I've just accepted that I'll stick with this one because replacing it could mean getting worse tint on the next one.

Yes this is what I'm afraid too. My first one had worse problems. Loose button which were rattling, imbalanced speakers and low volume output from 3.5 audio jack. I'm my country because we don't have Google Play Store for devices the replacement process is long and complicated. They agreed to exchange my first but they won't for a second unless it has a really serious problem. And yes I'm afraid I will get a way worse unit. At least the uneven tint is severe and I can live with it. Nexus and premium quality do not go together. Sure the 6P is better than previous Nexuses but it is also more expensive. I guess Samsung keeps the AAA quality AMOLED panels for themselves and sell to others the inferior ones. Before the 6P I had the S6 edge+ and the display and overall built quality was stellar. I just couldn't stand TouchWiz lag, the slow updates the nonexistent custom ROMs and the color shifting due to the edges. Google needs to improve QC of their Nexus. The 6P is a Russian roulette.

Clarity/resolution

The has a crazy crisp display. Just kidding, this is automated text so who knows if this screen is any good. So, you be the judge! A higher rating indicates that it's extremely sharp and clear, and that you cannot see pixels with your naked eye.
Then, drop a comment if you have anything to add!

First impressions of my 4 XL is the screen is yellow and warm face on, cloudy white, not impressed with the screen so I'm contacting Google today, the text on my 2 XL is clearer, the last thing I expected with the 4s was dodgy screens.

The color on mine was fine. I wonder if there are manufacturing defects with the 4XL that were present when the 2XL came out.

It's looking like that, mines warm, I prefer the cool look and seeing as Google doesn't put anything in their software to adjust coolness or warmness I'm not liking it, is yours pure white face on? Does it go any whiter when tilted backwards about 30 degrees?

Got a replacement coming 25-28th now, I'll see how that is.

Mine is very nice, it's crisp and vibrant. Surprisingly it looks better than my Note 10 plus.

You got a good one then nice, i had this problem with the 2 xl and almost gave up until i received this one i have in my hand, hard to compare with photos online because cameras are poor at white balance anyway when taking shots of other phones but in hand it's worse than my 2 xl which is surprising, my guess is Samsung is cherry picking displays for themselves first,

Just curious, but what color did y'all that are having problems, receive? Shouldn't make a difference,but that's the only reason I could see reviewers not mentioning it, as most of them got the orange one. Maybe it's coincidence, maybe not. But I thought I would out that out there

I really hope you get a better replacement because I'm real happy with mine. I was finally able to test it in direct bright sunlight and it was fine there too. Yes Samsung is brighter but I didn't have a problem reading the screen like the 2XL's and 3xl's I had. The 2xl was the worst out of the two but the 3xl was worse in direct sunlight for me. I wish you the best on your replacement and it sucks you have to go through that.

Glad your happy with it, this yellow is not something i can live with unless the manufacturer puts in settings and configuration to suit everyone, when i look at my tv then look at the phone I'm about to ship back I'm disappointed, I've noticed this white looks slightly better in bright light but in a duller environment the yellow shows it's rear ugly head, will see what happens in a few days when i get the replacement if that's the same must be how they've calibrated the screen this time, enjoy yours ?

Any oled can be varying temp etc

I just want to be rid of the black smearing in low brightness on my Pixel 2 XL. Should be arriving tomorrow!

This is what I've been reading about oled the last few days, there's just no consistency, considering how long oled has been out now it's shocking to be honest, if I bought a red ferrari and it was delivered light red I'd be pissed, should not be happening in this day an age, to be honest I'm beginning to think QC is just not there with Google, I've had Google phones since the Nexus 5 and never had issues with screens until the pixel 2 XL, no surprise since everything changed to oled, apparently it's a big issue with oled TVs too, read some bits some people have to watch their TV at a 70 degree angle to get pure white, it's just shocking.

Brightness sucks
If i return this phone (Pixel 4 XL) it will be because of the extremely poor brightness on this screen (i probably will return). The Oneplus 7t is better than this phones screen and cost $400 less. That's just pitiful.

I'd have to keep it on 100% brightness a lot of the time to get it where i want, with the Oneplus 7t and iphones, samsung galaxy - don't have to do that. Its just really low, and I think it's something with the way Google set it up that they could fix with software, but probably won't. Either way not paying $1000 dollars for this.

Absolutely no issues with the display. Will be testing it more extensively outside in the bright Sun.

No problems in the bright sun for me either. I tested mine on my morning walk and throughout the day with no issues reading the screen. This was a concern to me because the 3XL was terrible in the bright sun and I ended up returning it because of that. No, the 4XL isn't the brightest but it works fine. I've been testing it out along with a Note 10 + since yesterday and the Note is going back.

Yeah google ****ed that up in a update to android a while ago, mines 95% used to be around 60 ish, why they ****ed about with that is anyones guess.
But yeah OLED screens are a lottery, you either get lucky or the fact is probably a lot are actually yellow but a lot op peoples brains can't register or see it and they think it is white and they have no issues, See here on this link, more people actually voted there is tint issues than not.
https://www.avforums.com/threads/oled-yellow-red-tint.2119862/
Also Google uses LG oled screens, they are notorious for tinting problems in their oled tv's too, Don't know what the screen is the 4 or 4 XL but mine is ****e, luckily a replacement will be here tomorrow and if there is a big difference it will just go to show how poor either oled screens are or googles quality control is non existent, i read somewhere on a review on the 4xl screens (can't remember where now) and he says every single pixel 4 screen is calibrated at a factory, for a start that's absolute bull****, even expensive tv's are not calibrated individually, it takes way too much time so the fact there is so much variance in oled tells you where the problem is.

The slider adjustment was to make the increments more linear. Before, 50% on the slider was more than 50% of what a screen's brightness was actually capable off. So the difference between 0-50% was greater than 51-100%.
That being said, the dimmer than iPhone and Samsung's screens has nothing to do with it. The Pixel 4 is rated around 444 nits while iPhone's and Samsung's can hit 800 and 1000+ respectively.
