Differences in screen colours/brightness - Nexus 4 Q&A, Help & Troubleshooting

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?

same smartphone, lcd different colors

Hi guys, I bought 2 nexus 4 ... one for me and one for a friend ... these days I'm testing them both ... but by chance I noticed that the colors of the first are slightly more saturated, those of the second one are slightly less saturated and tend to gray ...
the first was produced just before the second
s / n 1 (301Kxxxxx733)
s / n 2 (301Kxxxxx738)
the two smartphones have the exact same rom, and the same programs installed, the brightness is set to a minimum in both...
Why this difference?
all the lcd screens vary, colorwise.

I see... I noticed something else ... in the second nexus 4 with lcd which tends to cool colors (it seems that the brightness is lower, even if it is minimized in both), the vibration is slightly less powerful than the other...
it is as if the amount of input current is different in the 2 nexus... possible?
EDIT: same for the notification led... in the one with the colors tending to gray and the vibration less powerful, the LED is slightly less bright

I see... It is possible they changed the energy absorption? to increase the duration of the battery?
even if the 2 pieces were produced 5 pieces in one away on the other...

Screen brightness levels old vs new

I got my RMA device today, and the image retention problem I had isn't as bad on this device. However I have noticed a considerable difference in the brightness of this device compared to the old one. The old one has a much brighter screen, and the yellow on the left is much worse on the new device. With my old Nexus 4 the yellow got better over time, so I think that might be the case with this one too, however will the screen get brighter over time? I doubt it. Has anyone else noticed a darker screen on the newer devices? My old nexus 4 was a 301K and rev_10. The new one I got today is a 303K and rev_11.
So has anyone noticed a difference?

Whites have a yellowish tint?

First of all, I love this tablet. The only complaint that I have is that compared to my 2 previous 2012 Nexus 7s (now sold) and my Nexus 4, the new Nexus 7 I just received yesterday has a rather different color temperature. Whites aren't white -- instead, it has a yellowish tint to it.
Are any of you guys experiencing this, or is this just an LCD panel lottery that I lost? I'm wondering if I should swap this one out at Staples, return it and wait for the next batch, or if this is a normal characteristic of the JDI panels used in the 2013 Nexus 7?
This is really confusing to me, because in the AnandTech mini review, the 2013 Nexus 7's white point average is 6940K while the original Nexus 7's is 6215K. So my new tablet should have a cooler/more blue color than my old one, but instead it's the opposite and looks warmer/yellow.
mine is like yours so I just think its that way but I prefer it actually
I'm seeing a lot of green wash into whites/browns with mine, and poor black levels (too bright.)
The effect is more pronounced if there's a lot of green in a photo to start with.
I've posted photos comparing what I'm seeing on this device with what I see on a Note 8 in some of the other forum threads on this device.

That gives me hope that not all the displays used in the 2013s look like this. I ordered this one online from Staples, so I haven't seen another 2013 in person yet. I guess I'll head to Staples and Best Buy and look at the demo units and compare them to mine.
Edit:
Reading the other threads make me nervous about exchanging it now. This one has no dust under the screen, no dead pixels, no random reboots, the wireless charging works fine, etc. Aside from the yellowish screen, it's perfect.
I've seen what you guys are talking about with different Nexus 10s side by side. Had one where white looks like snow and two others beside it piss yellow looking white. I wonder if that's due to sourcing the display from different companies. My 2013 N7 arrives tomorrow so I hope it's not funky.
Just bought mine from my local Best Buy tonight. My screen looks perfectly fine. Also, no random reboots(was on it 4 hours straight), and no dust under the screen. I'll check it out again in the morning, but keeping my fingers crossed that mine is good! I didn't even know there were any issues with them until reading this thread

Displays ARE different.
Get over it, guys.
With the Sony Xperia Tablet Z, many people also always complain about the display being too yellowish.
Some displays are too bluish, some have a reddish tint (like my prev-gen N7), some greenish (my SGS2), some yellowish (my Tablet Z).
That's how it is. Some people will shout: "But my Samsung has perfect white", bla... But this isn't true, either. Most probably their display will have blue tint, but they are accustomed to it.
If you want perfect colors, you have to buy Apple, and even then you can't be sure.
And now enjoy your Nexus 7,damnit!
I actually have a good screen, no reboots, (haven't tested wireless charging, probably should) but I'm not actually experiencing the yellowish tint. Try to download Dead Pixel Test by Ossibus Software from Google Play (only a 64kb app), launch it, then tap once to get to "pure" white. Post a picture (not a screenshot) of the tablet at that point.
EDIT: I've noticed that the xda app does have a yellow tint, but doing the dead pixel test reveals a pure white. This could just be xda.

yes, its a lottery. i compared 4 units now, all had different (from bad to worse) whites and contrast setting that effect the scroll blur, overall sharpness and black levels. there's definitely green push somewhere that comes of as yellow tinted screen overall depending on other settings of that particular screen or page you're viewing etc. keep on exchanging or wait for kernels with color control if they ever come that is.

Well, I've got an HTC Desire, and after every reboot, the display gets horribly yellow. Though, turning screen off and on resolves it. Thing is, displays differ from device to device. A friend has a SGS3 with overly cold display, the kind that made my eyse stare at it all the time
Then I look back at my Desire, and it looks yellow. But it goes off after a little time(the yellowish look).
What you should try is to lookat your N7 for longer periods of time, and you'll get accustomed to it
Perfect whites here.
Just wait. Custom kernels will allow you to adjust all of this. With my nexus 4 the colors were not ideal for me, flashed a kernel and choose from the many options of color settings. There will be something for everyone, no matter what colors you prefer.

we don't know that yet. nexus 4 color adjustments on kernel level were possible due to the exposed color controls. somebody needs to confirm if it's even an option with this device.

Correct. Even iPad 4s suffer from screen issues. Just Google "ipad 4 yellow screen" and "ipad 4 backlight bleed".
true, ipad screens is just another lottery.
i'm going to borrow this from another thread just to show how Nexus screen looks next to a good screen.

Definitely different white than my original Nexus 7. First thing I did was open Kindle in both, because I wanted to compare font sharpness, and I was struck by 2013 Nexus 7 looking yellowish compared to original, and thought I much preferred the softer look of the white on the original. Now, however, after using the new 2013 model for 2 days, when I compare the two, the new one seems white and the old one seems pinkish! So I think perception changes with use and familiarity.
I had far more noticeable white balance issues with Galaxy S3, and there was also a noticeable difference in white balance between Galaxy Note GT-N7000 and the AT&T LTE version.

I can't get used to it -- I have really low tolerance for this stuff. Especially since my Nexus 4 screen has good whites, and I'm sometimes switching back and forth between the devices. Or the 3 monitors on my desk that have excellent whites. It's too jarring.

I won't even get started on AMOLED screens on my past Galaxies lol
Thinking back, my very first Nexus 4 had very pure whites. My current Nexus 4 is more yellow than that the first one. So for the Nexus 7 to appear yellow to my Nexus 4, it's got to be really bad.
Just to give an update...
I decided to order one from Amazon yesterday instead of exchanging the Staples one. I figured that buying from a different retailer would increase my chances of getting a different batch.
The old one from Staples was made in June 2013, while the new one from Amazon was made in July 2013.
Overall the screen looks much less yellow than my old one! So yes, LCD display lottery

would you be able to provide some side by side shots by any chance?

Have you got yellow screen tint?

Hey guys, I've recently noticed my nexus 6p has a very warm/yellow feel to it when compared to other devices such as my old HTC one m7!
I did some reading and apparently the nexus 5x has had a massive problem with "yellow screens".
Now am I just being naive as I've never had an AMOLED display before or is there likely to be something wrong?
Also, is it likely to be software related as its affected both the 5x and 6p?
Thanks
Mine does not have a yellow tint, not sure about if it is software.
I am coming from Oneplus One. After two days with 6p it does have yellow whites and a bit of pinkish hue when looking straight at it, when tilting it disappears (pink).
Looking back at Oneplus One feels too blue on the other hand

Could it be the adaptive display?
I seem to recall the Nexus 6 having various screen issues upon release, too.
I switched adaptive display off and no change so I guess its not that. I think this is its "feature" and we have to live with it

It's just the way the screen is calibrated. This will be adjustable later on in development I'm sure.
yea, its how the screen is calibrated. i compared it to my oneplus and the oneplus has a more white color, though a slight blueish tint. the nexus 6p has a more yellow screen.
Loose Part(s) When Tapping on Screen?
Yes. If they don't tweak it, then surely the community will.
On another hand, does anyone have a hollow/loose sound when tapping on the top right quarter of the screen? The sound reminds me of a loose ceramic buttons on a Nexus 5. It feels as if it's behind the screen just right of the speaker but sounds as if it's out the side.
Could be the adhesive for attaching the screen... If the yellow goes away after a day or two the adhesive needed to cure. It's happened with other devices
Put it side by side with my Nexus 6. Apparently the Nexus 6 screen is super yellow, never noticed. The 6P is MUCH whiter. Looks great.
Ask Google if you should return it. I've seen some complains around about yellowish screens. During the reviews one thing that was pointed out was precisely the opposite, with the 6P having a much cooler screen than the 5X, way more to the blue (cool) than to the warm (yellow) whites.
A bit strange you find the opposite.

I bought it from Carphonewarehouse (UK) so I may speak to them!
Pink not Yellow
Mine's got a pinkish hue at certain angles, but no yellow. Have come from an S4, which has a much whiter screen. Changing to sRGB gets rid of the pink hue but gives ghastly washed out colours instead. Guess we have to wait for some kind of tuning facility.
I'm very disappointed in the screen calibration. The 6p has the same pixel dimensions as the Nexus 6 with the 6p having slightly more pixels per inch. When I play a youtube video side by side the 6p looks terrible!!! Especially since during the keynote they said they worked really hard to get the colors right on the screen calibration. I hope this can be fixed with a software update. I might be returning mine.

It does seem like the calibration is off compared with my old HTC one m7. However I just compared my 6p to a mates nexus 6 screen and his is a lot more yellow than mine! So that's made me feel a bit better.
Hopefullythis can be fixed on the software side!

I too have the pinkish hue but I have come use to this on amoled displays. Every single phone I've had with a amoled display has had a pinkish hue. So either I'm very unlucky and keep getting device after device with a bad screen, or I have eagle eyes and I can see it when others can't.. haha Some times people do not notice it. I think it really has to do with your eyes. If they are sensitive enough to see it. For example. I work for Swappa and me and my co-worker both had the international version of the Droid Turbo(The Moto Maxx) I had asked him if he noticed a pink hue, he said no he did not.. When we met in person I saw it right away. While it wasn't as pronounced as it was on my device, it was still there. He didn't see it.
Last night I was chatting with Derek Ross from phandroid and I showed him a pic of my 6p screen.. I saw pink..he said it looked fine to him.. lol I still might order a replacement just to see if the next one is like that.

Store bought or online?
I'd go there indeed. If they have stock they should replace it.
Saw below you tuned it with an app (which?) but that may not be a permanent solution.

It's called MOBTI screen filter. I just put it to like 15-19% opacity and only had the blue halfway, a tiny bit or red, no green and it feels a lot better. Obvs its a temp solution, but it shows it can be fixed by software changes!

Need a few questions answered before i decide to buy

Hello, sorry for the really long post.
my current phone is the nexus 6 and i plan to upgrade to either the nexus 6p or moto x in the next week or so but first i have some questions.
Firstly i have had my nexus 6 for almost a year and for the first few weeks i had 5 different devices as the nav buttons and status bar kept burning in to the screen after a few days or sometimes even a day of use with the brightness at about a third. After the 5th phone i just accepted the burn in and kept it but i was wondering if any of you have had burn in on the 6p. I know amoled screens get burn in over time but im hoping the 6p has a better screen and less chance of burn in than the 6.
Also does the screen go as bright as the 6? I checked in the store at a demo version and it didnt seem as bright at max brightness. But it did still have that yellow tint to the whites and pinkish tint when the brightness is at its lowest. I was hoping that would be fixed in this new phone but its not a big deal as i have gotten used to it from my nexus 6.
On to the back and i was wondering if it scratches easy and if so what would be the best colour to get so that the scratches are the least noticeable? Also i looked at another display model from a different store which wasn't a real phone just one of the fake ones you see and the N and E from the nexus logo on the back was rubbing off. Is this the case with the real phones or was it just because the fake phone in the store was made different.
Thank you

1. Too early to tell about burn in.
2. IDK, I didn't have the 6. It's bright enough to need to turn down.
3. I have mine in a case. If you are worried about scratches, then get the plain aluminum.
