A71 has a better screen than S20s? - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

I have just used an A71 with Super Amoled "Plus" and I can say that it has a better screen than the S20+ in terms of white calibration and contrast, S20s with Dynamic Amoled are all too warm and when you try to adjust it does not fit at all. Subpixel rendering is also noticeable due to its pentile panel. I know it's a matter of getting used to it but it's hard to see.

It is not better starting from Note10 samsung made the displays warmer to decrease stress on eyes , but you can adjust it manually throw display settings see attached screenshot, make it all way left to cool the tap advanced settings and tune the red and green to get same results as A71 , and make sure to close blue light filter also

Tab S 8.4 Screen homogeneity issues

The reasons why I purchased a Tab S 8.4 were its awesome screen quality and high grade processor. For the later, the poor touchwiz optimization and the average gpu led to disappointing results. But well, the screen IS awesome !
Or is it ?
At first, I was truly impressed. But after some web browsing and reading e-books, something felt wrong with the colors homogeneity. On white backgrounds, the right part of the screen in portrait mode would tend towards a yellowish tone, while the left part would tend toward purple tones. Nothing obvious, but quite annoying when noticed.
After trying around with different backgrounds, it become more obvious with certain colors. The one used in settings background for example: The left side of the screen is deep blue, the right part is much lighter.. and greener.
Further investigating the issue, I figured it is most obvious when watched in the darkness and using dark colors: RBG such as R:0, G:10 , B: 20 or even R:20, G:10, B:0
Did anyone else notice similar issues ? Would you guys mind trying to create a R:0, G:10, B:20 (#000A14) background and check the result on your tab S in a low light environment ? On mine, it results in an obvious gradation from dark blue to green.
Attaching some pictures. The rendering is not the best especially in the darkness, but the issue remains clearly visible.
There is something very wrong with your screen. Return it.

I second that, that is not normal
I concur with the others, get it replaced.
AMOLED screens can fail for any number of reasons (pixel death is the main one) , if yours is showing problems get it replaced now rather than live with it and have a more serious problem later.
We've seen this yellow color issue reported by a few others. Looks like Samsung let a few diseased horses out of the barn. I concur with the others. Return it.
Thanks for your feedback, guys.
I'd like to highlight the fact this issue goes completely unnoticed in most scenarios. A friend I showed it on white background didn't notice it at all, in movies/games/pictures I don't see it at all. I only felt it while reading, and even then it was not obvious, just a persistant feeling that led me to further testing.
Only the extremely dark colors seem to be affected, and even then it's only noticeable in the darkness. I will go back to the store tomorow and exchange it for a new one, but I'm wondering if the issue isn't widespread and simply went under the radar as its effect is hardly noticeable in 99.9% of the situations.
Did anyone else check at an homogenous R:0, G:10, B:20 image in the darkness with their tab ?
I personnally used Moon+ Reader's background color settings for testing purpose, pretty easy to set up.
New Tab S, same issue
I changed my Tab S 8.4 today for a brand new one. Same test, same issue: the background is still not homogeneous. The issue is visible in the darkness on dark colors such as the one used for the settings menu, which seems naturally gradated from deep to lighter blue on my screen.
Could someone else test and reproduce the issue on their tab ?
I have tried to reproduce what you're seeing on my 10.5 and honestly I can't. I'm not going to say the white is always 100% pure white but it's close enough. At the same time I'm trying to avoid looking for something that's not there for my Tab.

Maybe you can go into Settings / Accessibility / Vision / Color Adjustments and see if your calibration is off. There is a test there where you arrange tiles by color gradation and it adjusts your screen. I am having none of the issues you mentioned, but my 10.5 Tab also passed that test with no color adjustments required. Give it a try.

Test completed successfully. The calibration is fine, and the issue is not noticeable during the test. The issue is actually not noticeable in most usages, I only see it on homogenous very dark color backgrounds (the 10% darkest colors), and while in a dark environment myself. In most common usages, the screen looks fantastic and flawless.
Unfortunately, I often use my toys in my bed in the darkness. AND I am concerned about a possible defect that would get worse over time.
That said, tests on similar colored backgrounds on other AMOLED screens (PS Vita, Galaxy SII) lead me to think this could be a global issue with AMOLED.

Lol, to those of us with a perverse sense of humor we would refer to that as a hanging curveball.
Whatever issues you are experiencing I would take that over LCD light bleed any day.

Dear Friend. Like you I am very sensible in that point. I have a lot behind me and I can tell you, that homogeneity is something we can not expect from all types of modern displays, except the pro ones with a special function that takes care about this issue. Any screen has such issues, the question is just what type of and the intensity differs. The lower the light in our environment the more sensible our eyes get. The longer we stare into the screen the better we see all color details. Worst case scenario is a totally darkened room. Your eyes won´t get more sensible than in such a situation. Especially AMOLED displays will show the strangest kind of irregularities you would never see normally. I remember the Tab 7.7 -- in a dark room the screen was over and over covered with black circles. Wow ! The Vita shows strange textures instead. It is horrible.
My advice to you would be to start trying to avoid using your tablet or any display in a dark room. Turn a light on, it will be nice for your brain and eyes and you will not see the described things. It´s just a matter of habit, nothing else. You will get used to it and probably feel very well with it. Anyway there will still be the green haze.... Not to talk about the yellowish etc. stuff.
I returned the Tab S for a MiPad and it´s much better, really nice homogeneity (compared to other actual devices).
I had 4-5 iPad Mini Retina and all of them have horrible yellowish/blueish tint.
I had 4 iPad Airs, 3 were horrible in a similar way, now the 4th one is okay, I finally had luck.
I had 2 Galaxy 12.2 - the first one yellowish in a quarter, the second has just a slight, short yellow stripe on the bottom border.
I had a Kindle Fire HD + HDX - both with bad, ugly green spots at borders and corners. Also partially yellowish.
Once I held a Galaxy Tab 3 in my hands that was actually flawless. I was shocked. It never happened again. Was from a classmate.
Today I guess it was a mistake since I could not test in in a home-at-night-environment.
I checked dozens of Tablets in big stores here - guess what I found ???
Look at the iMacs .... Horrible yellowish tint. Horrible. It´s a shame.
I use my Tab S 10.5 in a dark room with some regularity. I've never experienced any of these odd artifacts you guys are discussing. My black screen is just black. Colors look right. White is white. I think its a fallacy to claim that all amoled screens face these issues. The amoled screen on the Tab S is the best most advanced amoled screen ever created. Problems from older devices shouldn't apply here.
Please remember based upon other user input, Samsung did seem to have a run of defective screens on these tabs they put out.
Here's a quick video test taken in a pretty dark room (it's daytime here). As you can see the screen is just black. There is absolutely no reason to avoid viewing your Tab S in a dark room. If you are not seeing the solid black I have demonstrated in this video I suggest exchanging your possibly defective unit.

In my experience 100% of AMOLED displays exhibit this behaviour, i.e. both Tab S 8.4 I've had! The first one (exchanged because of unhappy whites) had it so obviously that it looked like a diagonal gradient fade to one corner. The second tablet shows it as a slightly patchy screen, see attached photo which looks worse than the reality.
This is only visible in a completely dark room with the display set to its darkest (or close to), displaying a very dark image (my photo is of the spec. you mentioned - hence blue/green colour). To show this I needed to use an exposure of about 1 second, if you use less the image will appear black, likewise (probably) if you try to capture it as a video using normal ISO values in camera, the camera won't pick up the background.

All I can say is that is seriously messed up. My screen looks nothing like that and just as pitch black as in my video. Considering black pixels in amoled screens are basically turned off, they should be utterly and completely black and devoid of light. Am I misunderstanding and your picture is of a blue background?
All other dark colors should be solid without strange light effects as well.

It's daytime for me at the moment but yes from memory, if you display an actual black image then it will appear as black, you see this effect when trying to display an image that is almost black, at very low levels of light output the (my!) panel isn't even.
The attached image is R0 G10 B20 and on my PC looks black - it isn't I just used "ColorPic" to check the screen colour and it shows those values.
It's not a big issue but does appear when using in fully dark room with brightness turned down, I notice it in some apps that have very dark background colours (which you'd assume were black and see as such in daylight, but aren't).
Obviously under these circumstances an LCD would appear as a (relatively) bright grey !

Screen Calibration

Can anyone share their screen calibration settings? I wanna get the best whites possible. On my N9 I used to decrease the reds all the way to zero and my greens about halfway but this is a new phone with a different display and those settings aren't doing the same thing. So I just wanted to know what everyone was doing. Thanks.
I think natural mode supposed to be pretty much calibrated already and if you still wanted to tweak it more there is cool/warm white balance slider and rgb sliders.
There is whole bunch of tests here http://www.displaymate.com/Galaxy_Note10_ShootOut_1G.htm.

Natural mode can't be further adjusted. You have to choose Vivid to adjust RGB and color temp.
As far as best settings, it's difficult to say what yours should be. If the Note 10 is anything like the Note 8 or Note 9, you can lay four of them down next to each other with stock settings and they will all be different.
My Note 10+ seemed to have too much green tint and maybe just slightly cool. I left temp alone and just knocked green down one notch. But honestly, these screens are so close to perfect you can just leave it stock. Just play around with it, adjust it back and forth until it looks good to YOU. You're the one staring at it.
I have compared four Note 10+'s side by side, and all had different white points. Also, Natural mode was significantly greenish (maybe slightly yellow too) on all four devices. Personally, I feel like my Note8 has a better panel.
According to article I linked above and here again http://www.displaymate.com/Galaxy_No...hootOut_1G.htm Natural mode supposed to be calibrated and automatically switch between sRGB and DCI-P3 depending on content. (I guess sRGB for pictures and web, DCI-P3 for 4k TV) and can't be easily adjusted. Then there is Vivid mode which uses full color gamut, display is capable of showing and you can adjust it with sliders to your liking or calibrate using instruments. I can't tell you if all phones are properly adjusted at factory (probably not), but according to article the one they had was right on the money and mine seems to be fine as well. BTW the eye can be easily fooled and calibrating instruments are the proper way to adjust it, if you need it. Yet, it is my phone, I don't use it for pro use, so I adjust it the way I like it and mine is set as vivid and gray seems to be neutral gray as far as I can tell without any tinkering. YDMW.

One of the failings on Android, no color calibration.
You simple can't do it by eye and get all the parameters right.
It's fine for viewing but not editing photos until a company like Spyder steps up to the plate with a 3rd party calibration apk and tool.
Mine seemed best in natural mode with a slight amount of red added with an overlay apk and night mode turned at about the 10 or 20% level.
Lol, enough.
Just don't edit photo colors, temps etc. with or you may get a very rude surprise.

is it just me or is the display pretty disappointing

i don't know why i seem to be the only one, i always wanted a note because it's been praised as the best display of all time i finally got a note 10+ and the display disappoints me to no end, first off the colors are dull, my xperia xz1 on super vivid mode has more vibrant colors, second off the brightness it's not amazing if i compare my note 10+ to my huawei mate 10 pro the huawei appears more vibrant and bright, the huawei is running a custom rom, my note 10 + has custom white balance settings with green and red turned down to 0 and it's still too yellow for my taste the screen mode is itensive and yes bluelight filter is off, when i use the note 10+ on it's own i get used too it and i see no issues with the display but then i start up my mate 10 pro and get a much whiter better white and overall brighter image, my note 10+ is set to +10 brightness and high performance mode all auto brightness off and max brightness, white still appears dull colors appear dull, why am i the only one who feels this way?
Was gonna ask if your blue light filter thing was on. The white seers into my brain unless I have the filter on. This seems to be the best display I've ever used. And you're saying other phones are brighter? I haven't found a single phone brighter than this one. Maybe a defective screen?

The display is what everyone who see's my Note 10+ mentions first. They are amazed at how good it is...
Maybe a side to side comparison to another phone might show it up but everyone who's seen it goes gaga over it...

my tweaks are the following
max performance with brightness 10+ enabled and brightness slider to the highest possible settingm, intensive with the temp slider to the far left as in coldest as it gets then advanced white balance both red and green turned down to 0 blue turned to max meaning the screen should have an extreme blue tint it doesn't, i tried the google books method and blue light is always off when i launch the app so it's not that, i even tried calibrating colors under accessability where you have to rearrange colored balls result are almost identical to what i had with a slight yellow tint to the white so worse than before i turned that off again
i had this issue with the original display and now the replacement one when i havenothing to compare to white looks great colors pop screen looks good white feels slightly dull but it's hard to tell, but then i go back to my xperia xz1 or mate 10 pro and feel a huge difference in white and overall color performance, both displays pop a lot more than the note 10+
might i add i am ultra sensitive to warm displays so what looks great to someone else might look like a yellow mess to me i always increase blue on all displays i have my sony af9 is set to cold with all color enhancers to max i need colors that pop with no yellow tint what so ever, i am not a fan of accurate colors at all
Being the most accurate display of colors doesn't mean it'll be your favorite. Maybe you prefer less accurate (seriously, no snark here). But brightness should be pretty clear cut... No idea why yours wouldn't be as bright.

well i already know i hate accurate colors i want bright vibrant cold colors anything accurate to me looks dull and yellow the surface pro i have which is known for it's accurate calibration almost looked black and white to me until i got it decent by forcing intel control panel and increasing color intensity but the screen was so terrible on it i stopped using it i just couldn't deal with that display so it's been collecting dust ever since, my xperia xz1 is using super vivid mode with blue turned up to 171 the screen becomes complete trash without super vivid mode and it becomes the best display i have ever seen with super vivid mode turned on, i wasn't a huge fan of the display on the xperia 1 either that phone has no super vivid mode and the display was rather dull to me but the brightness and white was miles better than the note 10+ especially when it forced the brightness to max on apps like youtube (it dimmed outside of certain apps which i could not handle so i sent it back but on youtube the brightness was just mindblowing the white was so perfect and clear then it wen't gray as soon as it would dim when i exited the youtube app)

I would say the Mate looks slightly brighter and whiter. Not sure what could be happening. My screen looks great. I have to tone it down quite a bit so the images don't seer into my retinas. Simply turning off the blue light filter makes my eyes hurt.

I believe that the Note interface is more greyish than white. This is why even without the blue filter, if you do not increase backlight alot, it is not quite white.
It can be seen on the Home screen, when you group-up some apps icons in a folder, have a look at the white of the icons and compare it to the white of the folder itself. Not same white. The surrounding white of the folder is grey, not white.
Same goes for the google search on home screen, it is not white compared to the the white of say, the Google Apps icon.
Maybe try another theme if you do not like it ?

I have the same effect in original Youtube app. It is just a bad background gradient in the application. Don´t blame the phone....
When I open Messenger with black background and grey status bar at the top of the app in the same brightness level, there is no greenish effect.
I am also having uniformity issues. Very noticeable, unfortunately. As there are no 512GB Ultras available anyway ATM, O will just have to live with it for the moment. Maybe I get used to it...

mm weird, I see it in every single app with dark grey background, even in settings (w/Dark mode on), the bleeding is a lot bigger from the top right corner.
EDIT: Just checked the messenger app (FB messenger) and background is completely black so most pixels are off except for the letters and gray search bar but bleeding wouldn't be noticeable.

EDIT: Just checked the messenger app (FB messenger) and background is completely black so most pixels are off except for the letters and gray search bar but bleeding wouldn't be noticeable.

I've just checked it with Gmail since it is also a Google application and you can notice the bleed when the lights in the room are turned on and I try to cover the top of the phone to see it. After turning the lights off, whole app is equally gray so in my opinion it is just an optical illusion. If I recall well the AMOLED displays use some kind of dimming (tinkering with the frequency) in order to reach a lower point of the brightness that is not noticeable for human eye. Probably this can be seen when covering a gray part of Google apps in a room that has another not so bright light source.

I made a picture. It is showing a 5% gray test pic and supposed to be uniform. It is easy to see and I was kind of shocked when instantly noticing it the first time I was using it in the dark. Settings and many parts of the dark one UI are using grays in that range.
Anybody else? If it is rare, it will be worth pushing for an exchange.

I did the same test, I'm attaching a picture of my Note 10+ and the S20 Ultra side by side. Uniformity seems a lot better on the note 10+, however on white background the Note 10+ turns more red when I slightly tilt it while the S20 Ultra seems to shift colors a lot less and still white overall.
Still not sure if it's worth the hassle to return.
Ok, the fact, that it looks very much like mine can be good and bad ?
Could you please check, if is different at 60Hz? For me, it is clearly different.

Oh wow, you're right! I set it to 60 hz and QHD+ and uniformity on the gray test got noticeable better, still some green on top right corner and around the punch hole but noticeable less. I love reaaally 120 hz during normal use though.
Thanks for confirming, same here. I wonder, if this is something, that can be fixed in software... And if the rumoured 'dynamic refresh raze' update might change things.
Could please note people check their Ultras displays?
Same here with my s20 more visible at 12hz refresh rate with dark theme
Damn it, ok, then I really hope that it is fixable... Weird.
I am using smiled displays since Symbian Nokias, never had one, where I noticed it so much.
I remember all the Mate 20 Pros with LG screen had this issue buy way worse in some cases
https://www.google.com/search?q=mat...JtXpfSDsL9sQXomrbgDQ&rlz=1C1CHBF_enUS731US731
In some cases they were normal during the first days but the problem evolved until the display was unsusable in low light conditions, hope the same won't happen to our phone during the next weeks.
yeah I don`t have this issue I did the screen test in Gmail and download the app that does all the different colors including gray, at the lowest brightness and at other levels of brightness at 120hz its all uniform.

Mine is most noticeable at around 35-40% brightness and with 120 hz but still noticeable with 60 hz while on the note 10+ I can't see any green at all at any level of brightness. I think it's a quality issue and variation of OLED screens but not sure if it would count as "defective". Samsung doesn't do exchanges so it would be a pain to return everything and recorder without the promotions and reservation/pre-order credits. Ugh not sure what to do yet.
EDIT: Btw I tested with gmail and didn't notice the green in the app since it's light gray but as soon as I drop down the notification panel (w/dark mode on) the green is immediately noticeable. It's only with very dark gray that lookd almost black which is what Samsung use for all their apps (settings, calculator, messages, etc.) when dark mode is on. I wish they used true black so pixels were completely off like with facebook messenger.
I am also unsure what to do. I have to say, however, that this is the device that gives me the most uncertainty ever. For this opportunity price I want a good to perfect display. @vwite Don't you think that the dark grays are too bright as well? It wouldn't be so visible otherwhise. I also sent my picture to the 'write the CEO' address and a pledge to be aware of the issue:
https://www.samsung.com/uk/info/contactus/email-the-ceo/ (example: UK)
I will try checking in a store, which will be totally hard because of the light there. Maybe I will just order another one... Or a plus ?
Made another picture 'for the CEO' :silly: and will also attach the source image I showed on screen. To replicate:
- 25% brightness
- Show 5% picture in a dark room
- made picture with an S10+ on full auto

Thanks! Please let me know what they say.
Actually I ordered an S20+ now and will most likely just give the Ultra back in the first 2 weeks. Yes, it is a pain, but I really can not stand the screen as is. I am even putting it in its box before I have the plus and using my S10+ in the meantime - the green tint is driving me a little nuts.
I am having a hard time justifying the thickness and weight for a feature I hardly use (amazing zoom) while having an inferior main camera at the same time (focus issues).
i noticed this issue too on my 20+
it seems to be worse some days less bad other days
it also is very dependable on how much ambient light is around - eg is much more noticeable in dark rooms
and yes is an issue with Samsung dark mode that isn't true black but some dark greyish
other then this - all other colours look amazing = so not sure if the screen itself is defective
I do hope there will be a software update that will fix this or make it less visible

screen yellow tint on left side and blue shadow following scroll

At low brightness states between 5% and 15% , I notice
a yellow tint on the lift side of the phone, especially on grey background, but It's better seen in a dark room, like when I'm scrolling at night.
can you guys tell if it's a software or hardware problem.
I can't ignore that odd uniformity in colours.
There is also a blue shadow following my scroll down in the same conditions of lightinig and brightness.
Here's a link showing the problem
Here are some pics, I wish they are clear enough
that's called smear. it happens on all good amoled screen. it's even exist on 90Hz display ex: op7t. but it hard to notice it because of 90Hz refresh rate.

Thanks for replaying?.
So I just should cope with it?
Not going to improve, right?

It doesn't sound comforting when you say "good amoled screen" It means the technology is basically crap
Does it exist on Galaxy S20?

i have j7 pro, a71 and op7t.
j7 pro has less contrast than a71 and op7t. and j7 pro doesn't have noticeable smear as a71 and op7t does.
this is a refference where i get those information https://amp.reddit.com/r/GalaxyS9/comments/9brauw/black_smear_test/
as stated in link above, every pixel in amoled is on and off. when you're using black theme and low brightness and trying to scroll.as fast as possible. the led at certain location need to be turn and off as soon as possible. it makes smear noticable.
