Grey uniformity issue - Huawei P20 Pro Questions & Answers

So my p20 pro has a grey uniformity issue. You can check too with the display tester app. Switch to dark grey colour in the app. Bring down brightness to 1% and check in dark room. I have attached an image. I ll be getting a replcement, hope the replacement doesnt have the issue.

Here it is

My screen is exactly the same. Did you get your screen fixed?

I got my mobile replaced. This time its better. Though not completely uniform (there's a bit dark and light grey mixture) but certainly not like my previous unit
And also check the black crush issue on 0 brightness in a dark room. Play a video with perfect blacks and you will see light leakage on screen.

Ok nice! Maybe I'll try to get mine replaced too
Yeah I noticed the black rush while playing a game in the dark. I guess that problem still persist in your replaced phone?

SAMOLED Burn in !

Hello XDA users !!!
Just noticed a thin long black line (vaguely seen) running from top to bottom of my screen on total black background i.e Grey (as it turns off all pixels and making the image more brighter on a black background but it's grey & can be noticed on a terminal with green on black option) and similar spots on my SAMOLED screen but there's no problem with the pixels all of em are 100% healthy.The images are clear,vibrant & bright but still this flaw/disadvantage is bugging me..!
And we all know that SAMOLED and SAMOLED Plus displays from samsung are extraordinary & superior over the AMOLED's, LCD's , HTC's RGB 720P AMOLED(Rezound as explained in Engadget's review) as Super AMOLED advantages are brighter screens, less sunlight reflection and reduced power consumption (Source: http://en.wikipedia.org/wiki/Super_AMOLED) but after this experience and some googling i had just discovered that sooner or later maybe all the SAMOLED or any type of AMOLED display users are goin to face this issue/burn-in and even the display will change like this .
but that's an intermediate stage of burn in .
Hope this info was helpful and there is no fix for this unless you get your screen replaced when this chaos x( happens to your phone...
Please report if any one's noticed the same.
Correct me if i was wrong ...!
C'mon no response ..?
I got notification bar burn after the first couple months but to my relief it hasn't got any worse in 18 months... Yay!

Hi, I havent noticed any burn-in´s, but I´ve noticed those lines coming from top to bottom. For me it is the most noticeable on white background. I thought that the framerate is lowering down. Also it can be caused by CM7, will try in couple days to reflash back to SammyRom to see if it happens too.

Thankyou guys for your response ...!
and R34L2Pac please post your results after flashing sammy's rom.!
I doubt that's a burn in unless if you have a background with a line running from top to bottom. Burn in looks like artifacts that appears often on your screen, such as the digits for the clock on the status bar.
i run a BLACK theme, and even so i still got the status bar and its icon burned in on my Nexus S
good thing is, it's not noticeable unless you put a full white or full grey background on the screen
it's very easy to check with screen test

Yep, you are correct. Indeed i did mention that all pixels of my display are working properly & that weird problem made me to analyze, post a thread in here that could help many SAMOLED users to seek out any issues before hand with their precious devices

First of all, AllGamer (Moderator ) thank you for your response .
So, all these point out that our SAMOLED's are at a very high risk and even though you had a black theme your Nexus S but still it getting burn in.....
that's very sad .
by the way that app can't be tested on ICS .

Does anyone have weird vertical and horizontal lines on the screen?

I just noted (pardon the pun) that there are lines vertical ans horizontal lines when displaying white. This is my second phone. I went back to cpw and changed this one has similar horizontal lines. Its very very very faint, but I can see it. Im not sure why, it is because of the AMOLED screen, how it works?
Very annoyed. what can i do? every phone CPW has cant be faulty?

I've only had mine a day but cant see any lines like you've mentioned... maybe a bad batch they got in? Maybe something to do with the S-pen's digitizer screen, i assume that will have some form of grid to it
AMOLED seems to have weaknesses at low brightness levels.
Some have seen very faint lines .
Also on minimum brightness some reported a faint changing of the hue of the display.
The screen is also very bright (whites) on min brightness.
If you display a greyscale step pattern black is absolute black but
others that should be near black are too bright.
http://www.execulink.com/~impact/docs/utils/StepGray16G.jpg
I think its just the AMOLED tech but check the display thread too.
In normal use the screen is amazing,
all technologies seem to have good and weak points if you look for them.
You are not the only one with this problem. I'm on my third galaxy note now... The first one had dead pixels and the right side was darker than the left side. The second one had much more dark horizontal and vertical lines and smudges. The third one at first had very faint lines and smudges, but it is becoming more visible now. There are several threads about this issue on this forum.. My guess is that these problems are pretty widespread (more or less visible on some gnotes) and that there were some bad batches or that the Amoled technology is the problem. Would love to hear the reason to these issues from Samsung.
No lines on mine. White is white and everything shows up excellent.

If you disable the automatic light control and just snap the backlight up from 0% to anything above, you will not see any grayish things in video on the Note. I don't have this problem, but I've heard that some people have had to do this to solve this issue.
I don't have any bandings or strange lines anywhere on the screen. It looks as good as my Galaxy S II and Galaxy Tab. I haven't seen anything out of the ordinary (considering the limitations of the AMOLED screen).
There have been concerns about the lines on the white though. I don't have any of those on mine, but it seems some screens show up this fault. I don't know how to solve this issue and would recommend returning it as soon as possible.
Using the recommended gray test on the Note didn't show up anything but a solid grey screen on mine, although I've heard much people have dark spots all over. It might be something about where the phone was manufactured, or when.
My Note have never had anything wrong with the screen or anything else. The only problem I've ever had is applications that use 16 bit color instead of the Notes 32 bit. This will make color look strange at times, but it's totally normal.
Note that this isn't something wrong with the hardware, it's merely a software problem that will be solved as soon as ICS is released.

Lines/spots are due to ****ty quality control, this is just a matter of luck.

I have yet to see ANYTHING with more then 65k colors, even in the browser.
All i see is some VERY clever dithering very hard to see due to the high resolution.
Coming from the HD2, I'm really disappointed, nothing gained in 3 years (well, more pixels, so harder to see the flaws).
I took 3 picture with a green gradient:
1) 1280width, so basicly 1280 levels of green, but 24bit only shows 255.
2) 255width, so basicly 255 levels of green, 24bit.
3) 64 width, so basicly 64 levels of green, 16bit.
They all look the same to me, in browser and in gallery. I see dither in each of them. This tell me the whole screen is 16/18 bit only.
Maybe the PenTile is playing tricks with me...
Or the grainy screen lets me think its dithered...
i am facing a similar problem..whenever i apply some photo having a lot of black in it as my lock screen image..there seems to be some horizontal gray lines in it..but when i look in the gallery the black is pure black (no horizontal gray lines at all)...is there any problem in the software only ? or is it something regarding the screen?

P10 - sensor issues // screen gets dark in the bright sun

Hello dear xda-community,
I just returned from my vacation to Mexico. Whilst being there and taking pictures I encountered a very strange dilemma with the display and the brightness-automatic of the P10: Even if I deactivated the automatic screen-brightness, the system shaded when shooting pictures in the bright sunlight. Which resulted in a barely seeable screen, whereby the S7 of my girlfriend provided a sharp and bright screen.
I really wonder what caused this strange behaviour, and if anyone of you experienced a similar behaviour? I really don't get it why a feature still works when it's deactivated -__-
Thanks, cheerz
J
did no one experience this issue?
I experienced this, too.
But mostly I got it working with manual focus.
The most annoying thing is that the colors are a bit darken with bright sunlight, even if the sun isn't in the picture. The colors seems to be faded, the saturation is very low. See the attachment, the smaller prop plane is blue in reality but on this photo it looks like black, like the background buildings, too.
Hello Janno,
my issue is not with the postproduction, but with the lightsensor which is shading the whole display (even if this option has been disabled)
Thanks for your reply though, I chose a bad headline
Um getting this issue too... After about 10mins in the bright sun light the phone dims...even when i turn off automatic brightness and increase the brightness level it wont work...i think its a flaw on oreo update...when using nougat this never encountered

I guess it has something todo with the device temperature - Have the same behavior while using navigation :x
hm... not sure if it's really temperature-driven, since in the lockscreen no dimming took place and the display was shining in brightest and good readable colors.

Its a bug in the display, you can turn it off in developer options but it still occurs. I think B365 has a fix for it

B365 is an Oreo update.
I am pretty sure it is temperature issue, had it on oreo 360 and 365 after update. It happens while I am driving with navigation (waze)and charging and direct sunlight on the device. Then I take the p10 and place it in front of the air conditioner opening for 30 seconds and everything is ok.

So for me, it has something todo with the device temperature. I bought a new phone holder, which is placed in front of the Ventilation and my display didnt changed the brigthness anymore ?
Same problem
In application's it get dark even you have automatic switched off. This issue is a really annoying and looks like connected with temperature.
My P10 was/is on B365 as this issue happened. Just got it back today from repairs, of course they found nothing^^
So it seems really to be a software-issue. Any way to fix this?

Screen burn-in check thread

I think a lot of us have had our phone for about a month now, and this is my second OLED phone so I know how to treat it with more care in comparison to my old Moto Z Force. (look in the attachments ( :silly: ) [Ignore the cracks, they're on the glass screen protector, not the phone itself]
But, so far I haven't gotten any screen burn I on my Note 9 (I use an app called White to check it). I use about 50-60% brightness throughout the day and sometimes a little more during gaming and watching videos, an SOT of 30 secs, AOD is activated, so far so good.
What about everyone else?
Hey there .
You shouldn't check for screen burn in with this blue image
Try this dark green picture I will upload (use full screen brightness)
Or this app https://play.google.com/store/apps/details?id=com.oledtools
I've noticed some strange pattern on my phone not sure if screen burn in or faulty oled panel
I'll have an eye on it
None here had since release but then again I run full immersive mode so that always helps
One month old note 9 it's a shame
And I have no clue why
None of my apps have such an layout
Screen off time is 15 seconds and after I had screen burn in on my s8 I was really careful on my note
But I have to admit I am really not sure if this is really screen burn in or maybe structure stuff of the phone or the panel
I opened every app and I have no app that have this layout or anywhere close to it

Yeah that burn-in looks insanely weird, assuming if it even is burn in. I tried OLED tools and didn't notice any burn in on my panel there either thankfully, however I did try your dark green image on my phone and even at 100% brightness the picture looks black.
EDIT: Okay you're supposed to look at this in COMPLETE darkness, and I do see the green on my phone now, and from the looks of things I still don't see anything in particular burned into my panel. Though, is the picture supposed to be darker at the bottom than it is at the top?

Yeah I am also not sure might be the panel maybe structure thing (really checked every app for a similar pattern but there is none and I've seen burn in before I know what's causing it)
Sorry should have told you have to look at it in complete darkness
And nope the image should be everywhere the same green
Should be a slight green so the green pixels are just turned on a little bit
You should check the app I posted in the first post it's very useful to check for burn in or any other stuff maybe you can also post results j am really curious

Well, oddly enough the green image is a "bright" green at the top of my phone and gradually fades to black toward the bottom, but this isn't anything I can see in any other program I use. I used OLED tools but it seems to just be an app to swap through colors? I can do that using White

Yeah for me this pattern thing is also not visible (ATM I wish I never looked for this thread )only if you really "want" to see it
No no oled tools offers you different stuff in the main menu the first one it the one to test the panel
In this mode you can swipe to change the "brightness" of the color/pixels
And single tap shows a button to change color
Edit: so for me only the green pixels have this weird pattern blue and red are fine
My note 8 has some burn in ghosting from watching YouTube in non landscape mode. It's not horrible but its there for sure. Going to try to be a little more careful this time around. Also you tube didnt uave a dark mode until recently either. Not sure if dark mode will help

What kind of burn in you gout from YouTube ? Like where the video is or the down below ?
Cause I thought about that a few times and my s8 kind of stated that
Using black theme or so gives you kind of reverse screen burn in
So the part that is black wont burn in for sure but the other pixels that are on those are aging faster then those that are off because of black
So you will see that after a time
Call me crazy here but that's what my s8 had
I had black navbar and at the end the navbar was like reversed burned in because those pixels were not that often used then the other ones
That's what ive noticed
Ify theory is wrong correct me

I have this very same weird pattern visible on dark screens on my Note 9. Must be the panel or something else behind the screen. Thought I was the only one, but apparently not... Not sure what's going on.
---------- Post added at 01:08 AM ---------- Previous post was at 01:00 AM ----------
I would really like to know what's causing this. My phone is also only a month old. This device is too expensive to have this kind of issue with the screen this early. What's weird is that I noticed it several days ago but then apparently it went away, but came back today.
I'm stumped.

If this is affecting several users and their devices, then Samsung has a defective screen on their hands and needs to be made aware it! Please guys, let me know your findings and/or solutions to this. I can't see it at all on white or brightly colored screens. Only on certain dark ones.

So confirmed I am not the only one
Could you also post pictures of your screen like I did ? Would be interesting
These windows is where is most noticeable. Also has a very faint line under the top video box
I experienced burn-in on my Note 8 and S7 edge. Both were caused from a combination of having auto brightness enabled, along with heavy usage of YouTube while on my daily drives. I would have my phone attached to a car mount sitting on the air vents. While driving, the different lighting angles of the day would cause my screen to trigger daylight mode. I found out the hard way, that long periods of daylight mode watching videos was creating a burn-in on my screen. With this being a common problem, you would think that Samsung would consider this problem by allowing users more control on adjusting the daylight mode settings a bit more. Since then, I'm currently using "Screen Brightness Control(F-Lux)" to auto maintain a screen brightness between 35% - 70%. So far no burn-in on my note 9.
I've used the OLED tools and other tools to check burn in and it seems that i don't have any burn-in whatsoever, not even on the more used areas like the nav bar or notification bar. I use a system wide Amoled black theme that i created from the ThemeGalaxy app. I frequently run in fullscreen mode (or atleast try to) with a transparent nav bar with translucent icons. I typically have my brightness in the mid to high range but rarely full brightness. Even my most frequent used apps and system apps are completely black for the background and i use Vanced Youtube for the Amoled black background. Hope this helps for those that want to slow screen burn-in.
Today I am really just confused ?
Yesterday I showed you this dot pattern in my screen specials on the green pixels
Today thought like "take another look"
And it's gone
Everything is working like it should be
I have no clue why
Didn't change anything (only thing that comes to mind first is battery charge I will have a look again later)
But it's just gone
no dots nothing at all
Someone in this thread also said it disappeared and comes back
So let's investigate what's causing it

Yep, mine has done the very same thing. I think it has to do with when the phone gets hot and the water cooling system is activated... but that's just a wild guess. Will take many who are having the same issue to investigate and test it out.
This thread reminded me to shift my desktop icons around.
I had burn in on my previous Note 8 that had them stuck on the main screen.
Possibly a combination of Auto Brightness and Super Crazy Outside Brightness.
- Which I just remembered to turn off.
So...Keep your eyes OPEN!

As far as I know there is nothing to be activated with water cooling
This super carbon water cooling thing is just marketing bull**** ?
The note 9 have a noticeable bigger heat pipe than other phones and that's all
No real magic (search on YouTube "note 9 Jerry")
Yesterday I took the pictures with low battery state so I will drain battery now to the same amount and check
And also check your heat idea
Let's have a look
Use the displayed tester app by brainstree to check for screen burn in. Especially use the grey #8080 test card color. You can also adjust the brightness level by swiping the up or down . Normally the grey will show defects well.

Red tint on dark grey ie dark theme on brightness below 50%

There is a noticeable red tint on dark grey color everywhere while the brightness slider is set in range of 0-49%. Effect is more pronounced while using 120hz refresh rate and less while using other modes. 50% and above and the tint just disappears.
Does anybody suffers with the same issue? This is indian variant of the phone.
Attached image can be used for testing.
This seems to be a problem with many ROG 2 owners. The Red tint is massive at low brightness. And yes, this is a screen problem not a software issue.
Better try replacing the unit. But there is no guarantee new phone won't have the same problem as many people are reporting this issue.
I think maybe Asus is buying cheaper display from some other manufacturer, not Samsung. Here is a similar complaint thread on Asus forums -
https://zentalk.asus.com/en/discussion/11085/display-red-tint-issue-on-my-rog-2
And if it very troublesome for you, simply return it, ask for refund and buy some other device.
I will probably do that but samsung has that stupid hole. I sold my op 7 pro for this.
But 1 thing that is interesting is at 60hz the red tint is visible at 0-10% range. And the higher the refresh rate the more brightness range it covers like at 120hz its visible at 0-40% range. At 50% nothing of such sort is visible at any refresh rate.
It mostly has to do with that 1ms gtg ie grey to grey response time at high refresh rate. And yes all units will have that issue maybe not at 60hz but definitely at 120hz.
Lets see if asus has any response. I still have my return window left.
And now you know why others don't have 120Hz AMOLED panels, and why reviewers complain about the minimum brightness being too bright. Asus tried to mitigate these issues because the panels are only acceptable above a certain brightness.
I have an Indian unit and have the red tint. I don't have an issue as i keep my screen at 50% brightness. Hope in Android 10 apps use black instead of dark grey for the dark mode

Reality is that most apps including google ones are going the way of dark grey background, not pure black.
Also always 50% brightness? Don't you turn it down in room with no lights or low lights?

But 1 thing that is interesting is at 60hz the red tint is visible at 0-10% range. And the higher the refresh rate the more brightness range it covers like at 120hz its visible at 0-40% range. At 50% nothing of such sort is visible at any refresh rate.
It mostly has to do with that 1ms gtg ie grey to grey response time at high refresh rate. And yes all units will have that issue maybe not at 60hz but definitely at 120hz.
Lets see if asus has any response. I still have my return window left.

You sold OP7 Pro for this? Seriously bro? I mean unless one is a gaming fanatic, ROG doesn't make sense for someone who wants a overall great experience. It was evident that Asus has cut corners at many places when they priced it so low.
Even if it's 60Hz, red tint shouldn't be there. It's an example of not a good display.

OP7 Pro had its issues, I bought it on first sale. camera focus was not good, camera output was soft around corners while clicking text/documents for sharing. the screen though gorgeous looking was actually hard to use. i can recall a particular issue - i use phone pe and the menu for edit beneficiary was just in the screen space where it started to become edge and it required multiple touch to activate it.
actually rog 2 feels more premium in hand and the weight distribution is quite good as compared to op7 pro, it was top heavy. i have large hands so actual phone size was not the issue with either op7 pro or rog 2.
if one can ignore this red tint issue almost every aspect is better than op7 pro. screen above 50% brightness( which is actually not 50% screen brightness output, its just 50% slider) hdr in video playback works very well, its a quite brighter than op7 pro. Sharpness is less but only apparent on close viewing. Sound quality is better on speakers and louder too. Screen smoothness is much better. gets less hot then op7 pro, Cyber hunter on full was 47-48 on op7 pro, its 44-45 on rog ii. and the battery life is way better. There are much differences to be pointed out but the thread will grow.
Though the phone might not look professional in a meeting and i don't think it will receive timely android updates. But as a usable device i find this better than op 7 pro. If the grey management was not an issue this would have been almost unbeatable in its category and even in a higher category. op7 pro costed me 51.5k after bank discount, this costed 34k after bank discount.

Reality is that most apps including google ones are going the way of dark grey background, not pure black.
Also always 50% brightness? Don't you turn it down in room with no lights or low lights?
Agree. Said just a hope. The objective of dark mode is also to take advantage of amoled which is not met by grey. Hoping common sense prevails.
I hardly use the mobile in low light, if i do, i dont turn the brightness down

I'm swapping my Galaxy S8 in for this. How certain are we that this red tint is a hardware issue?

If you wanna see the issue:
1) go to a dark room or in a room with almost no light.
2) add "Screen Frequency" toggle in the status bar, and lower the status bar to show the toggles;
3) lower the brightness above 40-50%;
4) use the toggle to swap frequency from 60Hz, 90Hz and 120Hz.
You will notice the colour of the status bar itself changes… it's like is 80%grey and 20%red on 60Hz; 90%grey and 10%red on 90Hz, 50%grey and 50% red on 120Hz (it's like the status bar is dark-brown coloured).
And, then again, increase slowly the brightness: the status bar will be "magically" turn back to its natural color, dark grey.
This is a big issue for a smartphone which costs about 960American dollars here in Italy! I'm thinking about to return it...

This means international version suffers with the same issue. What they have done to achieve such high refresh rates and such low response times must be the issue. Now if someone from asus can confirm if this tinting can be fixed via software update or not that will be the main factor for either keeping or returning the phone. The issue is already raised in zentalk forum and i have also commented there and the mod also has accepted the issue in his demo unit.

It's so minor I've literally never noticed it (until using your test image just now) and I've been using this phone for almost a month now. I'm filing this under not an issue for me.
Not an issue for me. My brightness is pretty much always set to 50% and 90hz - never even noticed it. If you're running brightness down around 20% then you're either pretending to be on an Ethiopian diet, or you have an issue with over sensitivity of your retinas and should get it checked out asap

This only affect night time usage with lights out or in low lit environments where you will keep your screen brightness low. Daytime usage is perfectly fine as 50% slider is not actually 50% screen brightness. So slider % remains high during day.

Its clearly mentioned that its a non issue with brightness slider in range 50% and above. So you wouldn't notice it.
And by the way if you are using that high of brightness in low lit or lights out environment then maybe you have less sensitive retina and maybe get it checked.
This will only affect people who use this for night time reading and naturally dim the screen to read comfortably. If people use normal day brightness at night this will be a non issue for them.
The main point is is this a hardware or a software issue. And i have already hypothesized why this might be happening. You can read the posts above.

I don't think I would ever find myself in a pitch black room with just my phone and no other background light of any sort. I'm not that kinda guy
If you head over to the Asus forum, this is not a new issue. Asus have declared the reddish tint is normal behaviour of the screen at high Hz, so its hardware, not software, and operating as it should. Every handset will be exactly the same. If it bothers you too much, then maybe look at the Nubia Red 3S or Xiaomi Blackshark 2 instead. For me, its a non issue as like you said, i never drop below 50% brightness, and my retinas are poor, so I would never see it.. :fingers-crossed:
I always thought that xda subscribers were above fanboy-ism...

We are all fans of something! :laugh:
This is my first Asus phone, and I'm coming from a long line of samsungs (the latest being the Note10+) and for what I do with the ROG2, its performance creams anything Samsung has ever produced.. so, when a negligible issue like red tint (don't forget Samsung had blue, sony had red also in the past) I'm willing to forgive it because 99% of the time it doesnt affect me. If you call that fanboy-ism, then so be it..
Looks like, red tint in the display, issue is widespread in most of the ROG 2 phones .
Asus has confirmed the same, but refused to say, if it is a SW issue or HW issue.

There is a noticeable red tint on dark grey color everywhere while the brightness slider is set in range of 0-50%. Effect is more pronounced while using 120hz refresh rate and less while using other modes. 50% and above and the tint just disappears.
Does anybody suffers with the same issue? This is indian variant of the phone.
Attached image can be used for testing.
