Hi. I'm concerned about the white and grey balance on the OnePlus 5, because the OnePlus 3 had a very noticeable yellowish whites even in sRGB mode, and they are using the same screen technology and resolution.
Please post here your opinion.
Thanks you very much!

Hi I just bought a new sgs2.
And compared to my friend's one, it has yellowish tint (for all screen not just a part of the screen)
Don't have warranty and stuff. Is there like an app to change screen temperature?
(voodoo colour maybe?)
Coming from sgs1 user, I can't really say s-amoled is better
Anyone with yellow tint screen, please give me an advice...
Thanks

already did. they refer to yellow tint on the side only.
I have the same issue. My previous sgs2 had a yellow tint on the left side. I send it for repair and got the screen replaced. Now my whole screen is more yellowish, while my previous phone was more blueish (warm vs cold tint). I'm on KG1 now. The yellow left side is as good as gone though.
On 100% brightness the whites are really white, but below 60% the white and grey turn yellow.
I've searched for an app that allows you to change the color temperature but haven't found one. I've found a few that simply turn down brightness levels individually for R, G and B, but that doesn't work. Personally I'd like my phone's tint to be a bit cooler.

On a yellow tinted phone, the whites only seem white till you compare it beside a phone with a higher color tone.. thats what I also experienced.
guess we just have to wait for speedmod colour fix or voodoo color..
Is that being developed? I would be more than happy to donate a few bucks to anyone who can deliver such an app.

Have you tried changing in settings, Screen the 3 different configurations it has?. Try the fist one, i think it has too many saturation but whites are whiter (at least for my sight).

Tried dynamic but it was too sharp for my taste.
Okay, so, one of the things that's really disappointed me with some recent Android tablets I've tried out has been the screen's color temperature and contrast:
1. The Samsung Galaxy Tab 2 7" and Toshiba Excite 10 all had very cold screens, with very blue-ish whites. Also, contrast was poor on both, so reading ebook on them with black text on a "white" background was unpleasant.
2. On some Primes I tried, whites were a dingy yellowish color (although I'm not sure that's because of the temp or some other issue), while some were a nice neutral-to-warm color.
3. The Toshiba Excite 7.7 screen varies depending on how much black/dark colors are being shown, clearly a power-saving feature. On screens with a lot of whites, the temp is made much coolor and contrast is reduced. On screens with a lot of darker colors, temp is warmer, contrast is increased, and whites are much less blue.
So, what I'm wondering about the Nexus 7 is this: what's the apparent color temp? Are whites "white," or are they yellow-ish (warmer) or blue-ish (colder)? And how's contrast, specifically black text on white?
I know I'll get the darn thing in a few weeks, but in the meantime I'm not finding any reviews that say anything other than "great screen for the money." And unless someone's being really careful, it's tough to show screen colors and temperature in pics and video...
This is the app I used to test: https://play.google.com/store/apps/details?id=engn.test.screencolor&hl=en
Contrast - Black: Squares 6 and above are clearly distinguishable, 4 and 5 are just about visible
Contrast - White: All squares are distinguishable
Color Scale - Brightness: All squares are distinguishable
Color Scale - Saturation: Highest 4 squares are equally saturated on all but orange, light blue and grey
This is with an AUO panel and default white balance - I'm hoping someone with a JDI panel (or indeed another AUO) can weigh in with their observations.
what is wrong with your display then?
I have the JDI (Novatek) and confirm the same crushed black levels with Color Test and Display Tester - except that only 7 and above are distinguishable. White contrast and brightness are the same as yours, but color saturation tests vary between the two apps .... personally I trust Display Tester better, which shows blues only are moderately over-saturated.
The crushed blacks are definitely noticeable in dark scenes with or without X-Reality. The panel is quite warm compared to others, and the White Balance settings are somewhat useless since they involve an overlay filter, it seems, and so just darken the screen.

Yeah not too happy with the white balance setting compared to voodoo/cm colour settings on my old galaxy s, but gets the job done for the most part. Call me crazy but I like it even warmer than default
And hopefully there will be some software improvements to the display in Kitkat
how can i know if my device use JDI or AUO panel?
It says on the back of the screen

Assuming you don't like the idea of dismantling your phone to check the back side of the panel you might want to follow my instructions in this post.
Yes Louis has the best way, sorry for my late reply, only just got my screen back in. Mines a JDI

Z1c black w9 telenor-hungary auo-panel (no "blue" problem)
To dark, the dark areas (too high contrast/gamma), dislike me...
But, good deep-black.
Automatic background light regulation not a good idea (automatic brightness: OFF, x-reality: OFF ).

AUO Panel here. Results are pretty much similar in mine.
Color Scale - Saturation: The last 4 squares on the right end are clearly distinguishable for all except yellow and bluish green. Just about distinguishable for the green line.
On an unrelated note, I noticed that the INDOOR brightness level on the AUO panel is getting decreased by at least 4 levels on a scale of 100, when I put the slider to the lowest end and checked 'Adapt to lighting conditions'. You can see the difference very clearly by checking and unchecking the 'adapt to light' check box. Might save some battery during indoor use or ebook reading.
I started to notice uneven color or black botches under certain condition
the display look excellent during normal usage
- extreme whites & black are even and look fine, however the problem start to popup at dark grey just above the blacks i noticed a black botch in the lower display part
i detected the problem by doing the following
1- download (Full Screen Color Light)
2- Go to a dark room
3- set the screen color to dark grey, just above the black level
4- set the brightness to middle
5- noticed uneven gray color or black botches (similar to light bleed in Lcd)
Is this normal for super amoled display or should I RMA my device
note: issue isn't noticeable under normal light conditions
please help is everybody having this or should I RMA?
RMA the phone, that isn't normal.

Not normal, I have seen the issue though from the Galaxy S2, Note 2 and Note 3. Im glad to report that on my Nexus 6P the black is uniform and deep.

Black is deep and uniform in mine too, however the problem appears in dark grey only, as if not all the AMOLED pixels lit all together, or the voltage isn't uniform
making this pattern
appreciate if anyone can provide a picture of his dark grey screen in a dark room

I've always used the above link for testing how accurate my displays are. The tests on that site I've found most important in descending order are black level, white saturation, and contrast. (the gamma calibration test never seems to work well on phones)
The Axon 7 (A7) is my first AMOLED display. My old phone is the Nexus 5 (N5) with an IPS display.
On the black level test, squares 1-6 all blend with the black background on the A7, while the N5 only loses square 1 to the background. On white saturation, the A7's last visible square is 251, while on the N5 I can see up to 253. Finally, on the contrast test the A7 colours start at 2-3, with red and pink washing out the soonest at 21. On the N5 all the colours are visible at 1, and red and pink wash out at 25.
Through all these tests it seems the stock A7 AMOLED display is over saturated with poor contrast. On the stock ZTE firmware, the only display adjustments are in settings under "screen effects". Mine is set to Natural and Warm, but all settings here do not affect the test results.
I've read that after many complaints, OnePlus updated their firmware to give the OnePlus 3 special RGB calibration tools. Are there any apps that could do similar corrections on the Axon 7? Any rooted apps, or would CyanogenMod correct this?
It's becoming quite obvious when browsing photos or watching video, and especially takes away from the experience in dark movies.
