Color saturation & accuracy - Honor 8 Real Life Review

If you're colorblind, please disregard this thread. Rate this thread to express how you deem the color saturation and accuracy of the Honor 8's display. A higher rating indicates that you think that color accuracy is very high and saturation is excellent.
Then, drop a comment if you have anything to add!

Accurate? Nop. The display is way to cold by default. Even on the warm mode I can see a bit bluish. The display need some tweaking. Get it right honor!asap!

well saturated display, wish it was amoled

I haven't received mine yet, but the Anandtech review highlights the display as one of the weakest areas:
CCT: 8919K (should be 6500K, far too blue)
Average ΔE2000 greyscale: 8.82 (this is colour accuracy, and lower is better - this is one of the worst of any phone)
The red and green points are wide gamut, but the blue is short of sRGB.
They have more numbers, but needless to say the LCD panel is extremely poorly calibrated, and they claim that none of the colour calibration settings make anything better. I'm hoping in real life, it isn't as bothersome as in theory.
Can anyone who has theirs comment as to these specific concerns, because they're what's worrying me most...

It's rubbish really. Good contrast but nothing about it is correct.
*Gamma ranges from 1.2 in the midtones to 1.8 in the shadows, and just today I noticed it gets even worse if the ambient light sensor detects very bright conditions (gamma is made even worse to increase midtone brightness).
*Black level is 7 or 8 RGB levels too low.
*Color temperature is very blue and the color temperature setting provided does almost nothing, the range is too small.
No way to correct any of the above. Photographers and graphic artists should stay away from this phone.

This has me concerned, I was seeing the Honor 8 as my move back to Android (on an iPhone SE now bought in anger at the Nexus 5X's unbearable slowness), but it may not be. I couldn't resist $260... I won't actually get it until just before Christmas as I'm not in the US, it's being shipped to a friend.
Are there any third party tools that could fix this, or any hope of better calibration coming in EMUI 5? It seems like the LCD should be good, and it is a purely software issue...

Waiting to receive mine so I can rate in all of this threads.

I really like this phone. Is there any way to recalibrate the screen?

This has nothing to do with EMUI, it's not being developed by Honor.

Settings -> Developer tools -> Increase readability under sunlight to Off will probably fix the second part of the Gamma issue.

32 vs 64GB
Colors seems to be dependent on what device u have. Or maybe on what type of display is build in.
Actually i own two Honor 8, first one in blue with 32GB (since September) and the Premium version with 64GB in gold.
The 32 GB has a dark screen with blueish tint while the 64GB Premium version is the one that deserves his name. Rich colors with a nice touch of almost good balance in saturation. Should not be but it is so.

thats weired, so they are giving different lcd panels for different storage models??

I haven't heard anyone else mention it, so it could be a one off? I have heard of lines of phones shipping with the screens all calibrated (or not calibrated I guess) so that some ship with definite shifts in color so some units arrive with yellow, blue, pink, or green tinges to the screen.
In any case I would like it if Huawei had an sRGB mode option available.

This would be hard to provide given it doesn't sound like any calibration has taken place (given the reports of different panels). Reminds me of the Nexus 5... had three different Nexus 5s with different colour balance - one VERY different (warm and almost incandescent like, vs the very cool of the other two - one greenish and one purpleish).
You can't take a phone that hasn't been calibrated and go back and offer calibration... the screens need calibrated before they leave the factory, then you can offer calibrated modes. The best Huawei could offer us, really, is a gamut restriction (since the gamut is more or less a known) and RGB adjustment sliders.
They should offer at least the latter...

Agree

Here´s a (quick) comparison of my both Honor 8 (Gold = 64GB / Blue = 32GB).
Both set to Auto Brightness and both with same color temp.

Huawei Screen Red Tint Issue

Several /r/hwatch users are reporting a red tint on the screen even when it's supposed to be off (completely black pixels). Support tickets have been open but unfortunately there's no line to actually reach Huawei for support, only 3rd party call center (Knoah).
Are any of you experiencing this? Currently it seems to affect ALL Huawei Watches. See below for details.
http://www.reddit.com/r/hwatch/comments/3mcsdf/_/
Yup, did the test with a black watch face I did on Pujie, and I could indeed see a red cast when I went in a dark room. What would be the impact of this? It doesn't seem noticable except when you put on a completely black screen. When the watch face times out.. then it is completely black....

1. Ambient mode drains more battery than it should.
2. Risk of red pixel burn-in.
3. All images and watch faces are slightly more reddish than they are supposed to be causing it to look bad.
4. Dim faces on black backgrounds will have much lower contrast than they should making it difficult to read (like Wear Charge Widget)
5. For many, the Watch is their first Huawei device and first exposure to Huawei support which so far is proving to be pretty terrible. They have a 3rd party call center in the US (Knoah in Vegas) and no way to contact a Huawei employee directly to report the issue or understand what is causing it (is it hardware or software). What/if there is a fix. They have suggested swapping out the watch but so far all watches seem to be affected.

Same. I knew something wasn't right when I turned it on. Hangout contact images looked terribly over saturated and unnatural. And even in ambient mode, I could tell blacks weren't black like an OLED should be, putting out more light in a dark room watching TV. Huawei said it was only affecting a few devices and they'd swap it out but never did. So I bought another one overnight from Amazon and same issue.
Trying to raise awareness so Huawei will take it seriously because right now I think they are shrugging it off since they are the best reviewed smart watch.

Contrast (true blacks)

How well do you know your fifty shades of grey? Rate this thread to express how good the ZTE Axon 7's display contrast is. A higher rating indicates that black is true black, rather than a very dark gray.
Then, drop a comment if you have anything to add!
I am coming from an amoled screen, yet I am amazed at how black the black is on the a7. Using tbo Blacked Out apps are a no brainer.
Sent from my ZTE A2017U using XDA-Developers mobile app
It's an Amoled screen, meaning the pixels are off when displaying black. The blacks are...black.
What are the best color accuracy settings for the display?
I'll go against the grain and say I'm mildy disappointed in the Axon 7's blacks. Vividness and high contrast are appealing to the eye, but so much detail is lost.
http://www.lagom.nl/lcd-test/black.php
Above is a series of tests I use on all my displays. My TV and PC monitor are calibrated to have every black box visible on the above test. My Nexus 5 phone has all but the last box visible. My Axon 7 on the other hand loses six boxes which blend into the background.
I honestly don't think this is a limitation of AMOLED hardware but likely the software configuration. I would be happy if ZTE released an sRGB calibration tool like OnePlus did for their OnePlus 3.
You can watch night scenes from The Dark Knight, B v S, Zero Dark Thirty, etc and really notice how much dark detail you're losing on the Axon 7.
I specifically remember a B v S scene where Batman is in his jet fighting Doomsday. A shot of Batman in his cockpit looks near completely black on the Axon: you lose all the detail of his cowl/mask, and the inside of the cockpit.

Your judgement is misguided. The blacks test on the link I provided was not designed for any specific display technology. It says LCD test because it was posted online before AMOLED existed. It shows how the TV salesman trend of pumping up contrast, vividness, and saturation creates deficiencies in picture accuracy.
https://community.zteusa.com/thread/12745
On ZTE community there are several members who observed the same. It's especially noticeable to professionals in film, TV, and photography who are used to having colour/tone accurate displays.
If you put brightness to the max, you will see all the squares. With default brightness, near to the minimum, I lose 4-5 boxes (the first row).
That test is brightness dependent.
Ah, and I did it without the ambient being dark.

For my Axon 7 I don't get the same results: on 100% brightness I still don't see the six boxes in a dark environment. Changing the brightness on this phone has no effect on contrast or gamma.

Display Ghosting

I am noticing quite a bit of ghosting on the display. Especially white text on dark background smears all over the place during fast scrolling. Black text on white turns grey in a similar situation. The blurbusters ufo test ( https://www.testufo.com/ ) looks really bad compared to a 120 Hz amoled. Is this how the display was supposed to be?
When you buy cheap this is what you get. Mine has a red tint all over the screen at low brightness ... Very annoying.

Fortunately, I have no such issues. The screen is perfectly white on any brightness.
Same, my screen also looks good. Xiaomi is not OnePlus. Just send the phone in under warranty.
Just got my Mi 10T Pro and there IS screen ghosting
WTF xiaomi isn't this flagship phone???
Changing refresh rate to 90Hz is little better but still my eyes are bleeding
Except screen ghosting this phone is amazing
Hope they somehow update display firmware for faster GTG response
when scrolling on text it seems as if the text blurs and greys out until you stop and then it becomes the normal black again. It's really annoying when trying to scroll and read at any sort of speed. Anyone else had this issue /fixed it? I've tried pretty much every setting now and nothing really seems to help..
Obviously none of the reviewers mention this, but the amount of ghosting is disgusting. The 144 Hz is just there for marketing, and is pointless with the amount of ghosting this panel has.

My Mi 10t pro is perfectly fine, i am not experiencing any ghosting. Mine is EEA model
I had a OnePlus 8T and sent it back because of green tint. I regret doing that... It is a much better phone that the Mi 10T Pro in my opinion. Way faster/smoother and the 120 Hz oled display is far better than this 144 Hz IPS. If only it had a better camera it would be perfect. Not saying that the Mi 10T Pro is a bad phone, but the OnePlus was just a joy to use, whereas this feels clunky at times.

Well, I can do a slow-motion video, but taking pictures is the pretty much only accurate way to show ghosting I think. What else can you do to show ghosting?
Of course, taking pictures with a better camera will bee.. well better
I don't mind this type of ghosting, it's minimal in my opinion.

Honestly, I don't mind it either, it is just a minor annoyance in apps with white text on gray background.

Question edge bleeding at low brightness

Hello, tonight i was configuring my youtube app and i noticed very bad colors at the edge of the display, when the background is grey. I was in a complete dark room, the problem is most noticable when brightness is about 15%. And no, its not only the app. The bad colors are visible at a brightness from 0% to 50%.
Do you guys also have this problem?

The Mi 8 has it also, that is screen uniformity. It is hardware and it seems very common the last few years. I don't have it on my Oneplus 7 pro but it is also present on the Oneplus 8, Xiaomi Mi 9 etc.
Some folks say it is normal on oled but it isn't.
Why are the no problems with oled on Oneplus 7 pro, Samsung s10+?

so your unit doesnt have this issue?
i have the same problem,always visible when you have a dark(not black) background,note i had before 1 samsung s2,s4,a5 (the a5 when i was watching a movie in dark scene i could see a yellow brightness in one corner,it was awfull)and a tablet from the same manufacturer and all had the same probleme but at different level,my last Mi9t was parfect and screen didnt show that but my new F3 has it ,one side is clearer than the other one
As far as I know it is because of the AMOLED manufacturing tolerances, it seems to be really hard to get a perfect uniform display.
It shows at low brightness with grey screen especially.
Discussion also happend with the Mi 8 here:
https://forum.xda-developers.com/t/...moled-uniformity-issues-etc-for-mi-8.3843180/
Lol, I was just about to start a topic about this when I saw yours. Only dark gray backgrounds and top left is brighter then bottom right. Disappears at about 25% brightness. On the photo it seems green but not to the eye...
So if I send the phone back I'll most likely receive a new one with the same issue?

So if I send the phone back I'll most likely receive a new one with the same issue?

Lol, as u can see, my issue is in the same area, but mirrored.
I think, if u send the phone back, maybe u will get one with the same issue on diffrent corners. Only if u r lucky, u will get a good screen but then maybe the vibration motor starts crackling xD
I will keep my phone, cuz everything is fine for now
Well, yes, I'm a nitpicker really and there's always a small problem with a device it seems. I can't find anything else so I guess I'll settle for a small uniformaty of the screen. After all it's only with gray and in a dark surrounding. When watching a dark scene in a movie in inperceptable and maybe I can switch more elements to black using a custom rom (hope lineageOS will show up).
And maybe when there's a way to do DC dinning and not PWM it'll be better....

It is in general really hard to get a perfect display, be it on phones or on PC monitors.
Also TN and IPS panels show their weaknesses at "grey" colors, it makes the uniformity visible to the human eye.
Additionally trails and overshoot of moving objects on a grey background are most noticeable.
Not sure why "grey" is so devastating
I don't know. I'm from NL and here we have a lot of "grey areas" so guess I'll have to get used to it
Mine has a similar grey gradient visible at low brightness and solid colors, but it doesn't seem to be discernible in anything but settings. My old phone has a "perfect" oled though, so it's definitely possible.
Solid colors seems fine, or my eyes don't perceive it...
Probably the same case as processor cores: bins. Maybe they pay less for getting screens that are not 100% uniform?

Question [CLOSED] Poco f3 green tint issue

Hello iam a new member on XDA,
I want to ask a question, can the green tint on the Poco F3 be minimized with just a software update?
and this green tint occurs when activating the screen in dark mode, 120hz, brightness is below 30%, in low light condission and occurs when displaying dark gray, will this get worse for long use or not?
I was worried because it was my first time buying a smartphone with an amoled screen
Thank you.

Someone tried hentai os and reported that there was no green tint in that rom, so it is probably a software issue. Lets hope it gets fixed in future updates.

Yeah lets hope its gets fixed in futurs update, thanks for your answer.
I'm still waiting on delivery for my phone, cannot comment on the issue right now.
However, I think a future software update can minimzie the effects of the issue.
I'm not sure if it can eliminate the issue altogether since it seems to be a prominent issue with all OLED panels.
Thats called (not uniform issue). It cant be fixed by software update. No matter what you do. Similar to Oneplus 7t/8t/8pro as well.
Don't think I'll ever use the brightness that low, but I'll check my unit once it arrives.
I was contemplating on getting the Blue color which I think is a newer batch, but I pulled the trigger on the Black on as soon as the seller on AliExpress allowed shipping to Canada (didn't want to wait to take a chance and have to wait longer).

Xiaomi Mi 11X/Poco F3 display green tint issues on dark backgrounds to be fixed with future OTA update.​

I still don't think the issue is going to be totally eliminated, but I'm pretty certain the future update will minimize the issue.

I hope so, thanks you.
Sorry to say this but this is a difect inherent to the production of amoled screens.
i had 2 poco f3, the first( wich had also this difect) and a second one that i'm using right now that does have a perfect screen.
Having a good display is just luck, returning it might not solve the problem ( they can send you another one with a "bad screen") and the green tint is not eligible for repair
Software can't do miracles either beacause they can't calibrate a screen solely in the area of the problem and if they reduce the overall "green" of the display they make your screen purple on the "good side".
Also different displays are affected to different degrees so they can't release an update that is good for everyone

So based on your conclusion "green tint" on OLED type screens is a natural thing?
and depending on the luck of the buyer too
thanks for the answer.

Unfortunately, but it's true. Manifacturers doesn't see a partial green tint of the screen while displaying grey colours at low brightness levels as a defect.
Oneplus and Pixel Phones are also plagued by the same problem. you have to win the screen lottery to catch a good one
My K20 pro is oled screen and there is zero green tint in low brightness so it is not all oled screens. I think it shows more obviously on grey backgrounds so i will see if i use substratum black theme on apps when i get my phone that is if it fixes the issue.
you are right... its really obvious more when i have a OP7PRO next to it, the oneplus screen is perfectly uniform.
I will try take a photo with one next to each other.
This is the Poco F3 8 256gb Arctic White
Double post... idk why but xda gave me error.

I don't expect that. Do you really think that a software causing this?
Lower grade LED panel is the cause. Nothing new.
They can only try to "hide" the problem with some color profile management tweaks.

nop i don't think so, its sometimes less noticable depending on your screen colour settings but is always there .
During the day is hard to notice so is not that bad i guess?
But during night , man its impossible to don't see it .
Mine is like way too red on the sides and green in the middle.

I dont have strong background in electronics but this is my personal opinion. Please correct my terminologies.
I think, the quality of the Amoled display of Poco F3 is just too high. It looks like you are watching 144p video in a TV with 4k display to the fact that you can literally see the pixels. I think this is what happening here in Poco F3. The quality of UI esp. the grey is too low for the Amoled display.
What do you think?
