Hey, guys! I observed today that something funky was happening with the contrast and colors on my Pocophone screen. The black/dark background in apps like Youtube and XDA, both with dark themes and black or dark grey backgrounds, was getting light grey. Also, the contrast of the text seemed to change.These things happen when the top of the phone enters in direct contact with sunlight. If I cover the sensor with my finger, the screen gets back to normal. It appears to me to be an option to make text and content more visible in direct sunlight. Have you observed the same thing on your phones. What's your opinion? I'm using miui 10 Global Beta. Thanks

I noticed too. Seems a display feature
Neither this is bug nor faulty screen. That's because of Auto Contrast in display setting. Anyways you can change it.
yep, it's a feature... use standard contrast
Happens even when set to standard contrast. Cant seem to be able to fix it!
Set it to increased contrast, it solved the issue for me

Can you say where is that Incresed contrast option in Poco M2 Pro
So is it pretty obvious , or does ghosting usually happens on low brightness on every AMOLED display or is this phone only suffering from this ?
(I saw ghosting while I was horizontally scrolling a black picture of a gray background).
Can anyone confirm this for me ? ( Not a huge issue though , it doesn't happen after the brightness is increased)
Try with this image in lowest brightness
Zoom in and move it left and right you will see a trail of weird color trailing the black circle.
its normal for amoled displays
almost all amoled screen leave purple trails when switching from pitch black to some other color pixels.. don't worry about it
Ya when scrolling in app drawer the icons looks like wobbling.
Yes this has been the case in my Realme XT as well. When you have black background in the app drawer and there is any app icon that is dark you see the icons changing their shape while we scroll.
Even in YouTube when you turn on the Dark Mode and there is any video that is pitch black you may see it leaving a trail when you scroll through the feed. This is more often when screen is in low brightness. Is this issue for all other phones with Amoled panel or only with Realme XT ?
Amoled panels basically has the lowest response time in any display technology format except "Ink Display". Every individual pixel lights up individually from switch off (black) to on (any color). Higher the brightness means higher the color spectrum shining into your eyes and thus it let you see no ghosting while at peak brightness. It's still happening but we dont usually see that clearly. Ghosting is very natural phenomenon of Amoled technology. Also these budget Amoled panel tends to big fan of burn out. So make sure you are using live wallpaper that changes or moves (stock one that comes with the ColorOS is good enough).
Anyone who wants to adjust the white balance of vivid screen mode to 6500k - here are my settings, done with a laser spectrophotometer. Gamma is 2.207289 and delta E is 0.3
While every screen is a little different and ideally needs its own calibration, these settings should probably be better than the default settings. with all sliders cranked up to 100%.
With sRGB set on in the developer settings, you'll get a natural looking photo with very slightly more saturated colours than the equivalent photo displayed on a fully calibrated and profiled wide-gamut desktop monitor (it's worth noting that in natural screen mode, the match is very accurate when compared to my monitor and if you're wanting colour accuracy above all, then put it into natural mode)
In the screenshot below, there are four white dots to the right of the green slider position and one white dot to the left of the blue slider position. The red slider is at 100%.

That looks identical to how my N10+ looks in natural mode @50% brightness.
Color/gamma calibration/accuracy are excellent on the N10+.

Not needed... if correctly calibrated from the factory. Color/gamma calibrating by eye is impossible... it won't work.
If you use the phone a lot in the sun ( definitely not recommended!) the vivid setting will help compensate for the bright light color washout.
Noted, thank you and thank you.

Cheers buddy, it's really help, like it now looks great.
Sorry if this is a silly question but where on the Cool/Warm scale do you have your marker, there are 5 dots there but these aren't shown on your screenshot above.
Thank you for these settings, much appreciated.
Guess this doesn't matter at all when using Eye comfort shield?
That cool/warm slider is a very blunt instrument, so it remains exactly in the middle with the settings I showed for the RGB sliders
Eye comfort shield messes with the white balance by reducing the blue component, so while you have it activated, you're right that this doesn't matter

Great, thank you very much.
I found using the Eye Comfort Shield fixed the white balance AND restored the saturation level of the the S22 Ultra. I prefer cooler tones so I set it all the way to the left. By default, the S23 Ultra screen is less vibrant than the S22 Ultra so this works great.
Thanks for this.
If you get chance, can you check some different areas of the screen with a white background to check uniformity. Mine seems a bit brighter in certain areas. Just wondering if I've got a duff one or not.

No it's not. It's ok for 3 years ago but in terms of today it's average.

The in depth test results on any variable refresh rate display will show the fallacy of your statement.
They are impossible to accurately calibrate across their many brightness/refresh ranges.
The brightest variable alone skews color calibration/accuracy which has a exponential effect on the gamma calibration.
This is one big reason I blew off the N20U was it's variable rate display. In terms overall color accuracy/calibration/viewing angle color shift the N10+ is one of the best smartphone displays ever produced. There are dozens of test parameters.
Samsung can't even get their basic display lamination technology right now let alone the much more difficult display color calibration. In Samsung's defense variable refresh rate displays are impossibly hard to color calibrate through their many brightness/refresh rate ranges. The differences are small but there. The higher brightness levels of these newer displays are making calibration even more difficult like it wasn't bad enough already.
This N10+ display has well over 8K hours on it and is still perfect. Zero detectable flaws or pixel fading; excellent longevity. Time will tell... ain't bragging but you see how chill I'm hanging.

Hello, good day to you, could you please elaborate on that? I'm not knowledgeable enough but as I do understand is that vivid mode uses wider DCI-P3 color gamut (on some percentage) so why do you suggest to use sRGB in developer settings?Also you said that natural mode looks more accurate than vivid in comparison with your display (you didn't tell if it is wide gamut, but mentioned earlier "...fully calibrated and profiled wide-gamut desktop monitor...", so I assume you have exactly this one), as I get it , this can be true if your monitor has a sRGB emulation because other spaces should make same colors more vibrant, saturated. Again, I can not say it for a fact, just want to know whether I'm right or wrong, would be glad to read explanation on how actually things work, thanks in advance.

Yes, my monitor is wide-gamut. I'm not 100% sure exactly what you're asking, although I'll try to give a short explanation on colour management. This info is not specific to phones. It's general colour management information. There are lots of resources on the net if you wish to learn more. Some of the info below is guesswork, since Samsung's colour management is a bit of a black box.
Android 13 is colour managed. That is to say, ostensibly it has all these components for a fully colour managed workflow, although many apps are still not colour managed.
On a properly calibrated and profiled desktop system, any photo should display using the same colours and look identical to the way the same image displays on a different fully calibrated and profiled monitor. For example, a calibrated and profiled AdobeRGB monitor should display an identical sRGB colourspace image to a properly calibrated and profiled sRGB monitor. This is how it should be.
Take, for example, the RGB value RGB(255,0,0). On a wide-gamut monitor, this maximal red value will be a deeper shade of red than on a smaller gamut sRGB monitor. So when no colour management is present, this would mean that instead of displaying the correct sRGB red primary colour, a wide-gamut monitor would display its version of the red primary, which is way more saturated (deeper) than the sRGB red primary. Colour management ensures that the sRGB red primary will map to the equivalent red hue in the wider monitor gamut and thus display correctly.
On the S23U, the display device profile shipped with the device appears to be non-standard and deliberately displays more saturated colours - I assume this is precisely what is intended by the "Vivid" setting in Display Settings. It looks almost as if no mapping is being applied between the image's sRGB colourspace and the wider display gamut, resulting in more saturated colours. Why Samsung chooses to do this, I don't know - it's probably because these cartoonish looking colours are seen as a desirable marketing feature. Without access to the source code or detailed technical documentation on Samsung's colour management implementation, it's just guesswork as to what they're doing. It's why the icons look more saturated in vivid mode: their sRGB colour value is being displayed in a wider-gamut space, resulting in a more saturated colour.
To partially fix this, setting sRGB on in Developer Settings is supposed to force the display's gamut to emulate sRGB when displaying pictures and so the image colours display as intended rather than in the over-saturated form that Samsung thinks consumers want (although it seems to be less than perfect in its emulation of sRGB to be honest, as it still looks a little more saturated than when using the Natural colour scheme). One would reasonably expect that pictures displayed when Picture Mode sRGB is on with Vivid mode to be the same as how it would look if you set the display mode to Natural, although it's not a 100% match (it's close). This Picture Mode setting is essentially a picture-specific sRGB mode as opposed to the system-wide natural display mode that forces the display gamut to emulate sRGB at all times.
This Picture Mode setting apparently has no effect when watching videos. It only affects pictures. As an aside, having watched several videos encoded in different colour spaces in the different S23U display modes, video colourspace mapping appears to work properly (ie. no over-saturation). Most Youtube content is encoded to REC.709 which has a similar gamut to sRGB (REC.2020 is used for HDR and is much wider gamut). I've watched a combination of REC.709 and REC.2020 videos on the S23U while running the same video on my desktop at the same time and the videos look identical on the S23U. In fact, video colour reproduction looks remarkably accurate.

Natural mode should produce near faithful reproduction*. Vivid is intended for bright lighting conditions like outdoors to reduce the effect of color washout.
Using a standardized color chart makes set up and verifying work flow much easier.
*On the N10+ is this mode color accuracy is excellent cam>display, I verified it with a color chart shot 50% brightness (I think it was), natural mode, image shot with noon sun. I couldn't see any deviations on the N10+'s display... not bad for an Android.
However haven't verified that on a known color calibrated monitor. So there's that
I have big problems with the screen and cameras.
Compared to my previous phone S22 Ultra the s23 ultra has a worse screen - faded colors, turns green and blurs details in photo-video. Front camera - now captures less detail because it has less megapixels. The main camera shoots with a green tint. When s22 photos are as transparent as possible.
Am I the only one like this in the world? Or what?
1 photo - s23 left, s22 right
2 photo - s23 right, s22 left
3 photo - s23 top, s22 bottom
