Hello,
I want to ask you about a problem I have with my phone. I recently saw a stripes on the screen with kind of different color/brightness. They are not very visible but really annoying! They appear everywhere. They don't move when I rotate the phone.
I have attached a picture which I took with a camera but it's not very visible so I made fake image with the Photoshop so it can be clearer what the problem is like.
Thanks in advance
try a different kernel, flash a stock ROM, then take it to Samsung
i have the same i think its screen burn
So do you think I have to change the digitizer or lcd?
the service center will decide
Guys,
I have only had my Z2 a few days so am still assessing the good and bad.
However, if I had to single out one bad item I have found it would be the White Balance on shots taken with the camera. These shots are clearly out when it comes to Reds and Blacks.
As an example if I take an evening shot of a lit street; although the lighting is Orange the colours from the lights bouncing down onto the road are Red.
The bricks on houses are way too saturated in Red, in fact most of the shot taken produces a Red element especially anything that is Grey in colour.
A similar situation is with Blacks; here I see Black turned into a bright Blue.
Now initially I was going to return the Z2 back to Phones4u but after altering the White Balance settings from the Settings/Display I managed to eliminate most of the incorrect colours.
Had everything been incorrect in colours and with that I mean all the screens from all other Apps and not just the cameras shots taken, in other words if the phone itself was producing incorrect Whites on all the screens I would have understood but all the other screens from all the Apps have a correct White setting, it's only the camera that is showing incorrect colours and I'm sure I should not have to alter the Settings/Display White Balance to set this correct. That to me is badly set up WB setting on my particular Z2.
Anyway, In order to ascertain the level of incorrect WB may I ask what settings are you using for your general White Balance in the Display Settings? If you have not altered the settings and you are happy with your shots as in nothing indicates the problems I have found then can you say you have not altered your White Balance.
As I have mentioned, I found the standard settings resulted in the shots taken having a strong red tint. So I applied a setting of the following to correct this:-
Red = 0
Green = 177
Blue = 177
These settings seemed to bring the colours back to normal…
I would appreciate your settings which ultimately will help decide whether or not to return my Z2.
Thank you.
Those settings are only for the screen, it doesn't have to do anything with the wb of the camera. Might look on display different / better but it doesn't effect the pictures themselves...

I'm happy that the shots taken will be okay on a different device say a PC/Mac or whatever but I most definitely notice a difference when viewing the shots in the Album App.
Try turning off the x-reality option in display options then check the images again in the album app, I had to turn it off due to it making some pics look strange, it basically makes the colours on images look to poppy like Samsung displays. A pic of my gf had blue halo around her face with x-reality on, with it off the pic looked normal.

Thanks but that was the first thing I did.....
Yes, it erased the saturation but didn't change the colours on screen.
Only by altering the WB could I get the shots on screen to look correct.
Here's my problem with my Galaxy S3 I9300.
The colours are too saturated and too bright (washed out). Display is also pixelated that is better seen on dark background. I tried to change the color scheme, the brightness settings and even hard reset the phone (through Settings > Back up and reset > Factory data reset), but nothing has worked so far. The screen is still weird.
I have attached pictures of how my screen looks vs the screenshot of how it should really look and also attached the Black box image test found here.
Black level - Lagom LCD test
and how it looks on my S3 and what happens when i pinch to zoom out
The day i got this set, i tried to tweak some contrast settings with help of some different apps but nothing made it better so i let the phone rest for a bit and later when i picked up the phone, the colours were perfect and all fixed. The display was flawless for a couple of days until today the issue came back out of the blue when i unlocked the screen in the afternoon. i tried restart, taking out battery. I even opened the set and tried cleaning the LCD contact on the motherboard but nothing worked.
So, my question is: does this screen problem sound like a hardware problem or can it be solved by software? If it can be done through software, what can I do?
Thanks in advance!
If a factory reset doesn't change the problem then I bet it is a hardware problem...
Yesterday night I noticed that black pixels do not switch off completely on my phone. (as they should on AMOLED, right?)
Try it this way:
Set your screen brightness to almost a very low value.
Now look at a picture which has a black background and very little color in the middle etc. The room has to be dark, otherwise you wont see a difference. (You can also cover your had with a blanked etc., just wait a moment, so your eyes get used to the dark environment).
Hide the statusbar, navbar etc., so only your picture is shown (Tap on the picture once in Google Photos).
When you disable your lockscreen and switch the display on and off a few times you'll see that the picture vanishes first and than the display goes completely dark. It looks like a very light yellow back-light.
Another way:
Again in dark environment power off your phone. Switch it back on and watch the bootlogo. The surroundings (everything that's black) is truly black and "switched off" and than some secs before completing boot the "back-light" switches on.
I tried to find a solution for that. The only thing I found is a setting in Kernel Adiutor named "Minimum RGB value" under the screen section which is set to 35. However lowering it to 0 does not work, the value get reset to 35 every time (Higher value does not change anything either tho).
I'm running Oxygen OS 2.2.0 with bluespark kernel + root + xposed (Gravitybox + XInternalSD)
maybe the black is not that black?
edit: just tested with fullhd resolution black picture and red dot pixel in centre(PNG file, not jpg nor bmp) and everything is working as intended - black is pitchblack(same as when u just block/shutdown ur phone)
edit2: i'm not having my reflex by my side this couple of months, but you can check it making a photo in light isolated room with low shutter speed(20sec should be enough, if they really produce light)

Thank you for testing. I reproduced your result with a #000000 PNG and everything seems fine, as long as the brightness does not go below a certain value. Turning auto brightness off and sliding the brightness completely down enables some kind of light in the whole panel.
Could it be some android feature, which put's a light overlay over the the screen image to protect the eyes in low light environments, like these warm filter mods?
I have a Samsung Galaxy Tab S3 and it's great but I can't figure one thing out. Which is the screens contrast. Dark scenes in Netflix or VLC player are too dark and hard to see. I tried different brightness settings, with/without blue light filter and the other color correction option for cinematic mode but nothing really works properly.
Is this an issue with the tablet or is there another setting to change the contrast or something?

I also noticed this with Netflix. Was hoping that turning up the brightness would help but it doesn't.
YES, YES, YES, I am shocked this isn't widely reported, I couldn't find almost anything about it and I've been searching for quite a while.
First of all it is really crazy that popular apps like plex or netflix don't offer any capability to change the brightness of the video played. No, we don't change the colorspace, black levels, bla bla bla.
I DID find eventually a solution (the ONLY one that works, a bit clumsy as it is): http://phandroid.com/2016/03/22/twilight-app-reduces-dark-contrast-on-samsung-galaxy-s7/ (yes, it's for the S7 and yes I did notice there the same issue, which makes it even crazier that it isn't something widely known and fixed).
I just picked up an S3 last night and I'm having this same issue. I watched the opening scene of The Defenders on Netflix, and I could hardly tell what was going on. Rewatched it on a proper display, and you're clearly upposed to tell it's Danny Randy much earlier in the scene, but I had no idea in the S3 until a blue light was clearly shining on him from above.
I used Twilight on my Nexus 7 because it lacked a night vision mode, ala blue light filter on the S3. I'm not sure how that can really help. Surely other people have found more elegant solutions to this problem? I've opened up other media files and they're all simply too dark. I get it's an HDR screen, but surely it has a mode for non-HDR content!
Do oled display have a blue light problem, I though it was only really a led thing.
John.
Might be an inconsistency with the displays. I have no problem with mine. Not getting any lag either but running a heavy debloated rom also. Battery life could be better. It's stupid you can't turn off the Wacom digitizer when s pen not in use. On my note 4 when I lost my s pen battery life was terrible because the Wacom digitizer stayed on. Should be an option in settings to turn it off. If anyone knows how please let me know. I don't use the s pen very often.

Try switching from "adaptive display" to "oled cinema".

Switching to modes other than Adaptive Display just gives me seemingly the same shade of yellow....
I have tab s2 and you can't change adaptive display. I wouldn't have bought this tablet if I'd known about this issue. Very annoyed.
I actually have the issue on my Samsung Tab S2, that the colors are really "hard" and lots of color information are missing in the video, details are lost in dark areas. Is there some fix for this or is the screen just too bad on the Tab S2? I know the Tab S3 has a HDR screen, and the S2 not. I dont have any HDR screens actually, but I can put color range to "full" on my desktop PC, which will en-light colors a bit, making details more pop out in dark areas (though black isnt fully black anymore if so).
Any color profile other than basic is mostly unusable, too much saturation. Still dark areas lack lots of information. Is there no way to fix this? I tested this actually
https://phandroid.s3.amazonaws.com/wp-content/uploads/2016/03/Screenshot_20160321-154452-400x711.png
and it helps with the details in dark areas, but it also makes the black bars of movies in Netflix and video players not black anymore but gray.
So from what i can tell, it's only a stock rom problem. As the screen looks amazing running liniage (best screen in the house). But I've recently decided to go back to stock debloated, as I think its running a bit snappier than liniage 16 or 17.
Has anyone found a black level fix for stock yet? (preferably not a screen tint app)
Touch the left hand side of the screen when watching netlix and a brightness slider appears

:cyclops: It's beyond what you're suggesting which is known :cyclops: but thanks for it
EDIT: I have now found a full workaround. First you need to enable Blue Light Filter. Then go to Settings > Accessibility > Visibility enhancements > Color adjustment > Personalized color, and choose all the colors in the correct order. If you do it correctly there won't be any change to the colors and Blue Light Filter will be "on", but actually not, which will override whatever Android is doing that's making the dark parts of movies way darker than they should be. So far I haven't found any cons of this workaround.
Original post:
Sorry to resurrect an old thread, but after trying to fix this problem for like half a day (lol) I think I found the best workaround so far. If you turn on Blue Light Filter and set its opacity to minimum, the filter will be barely noticable, but the brightness issue will be fixed.
One thing I noticed is that not all apps have this problem. For example VLC, Youtube do have it (you can even see the transition of colors and brightness for a second when exiting to desktop view). However Youtube Vanced doesn't have this issue, so I asssume the operating system does this dumb change of colors when it sees certain parameters in an app (maybe something in the manifest.json file?). It would be awesome if some more knowledgeable people could look into this issue, maybe they could find something about why YT Vanced has normal colors.
