Hello!
I recently got the Arc S and I love it, but there's something about the screen that freaks me out. It's hard to describe, but let me try.
When I scroll through menus, objects get darker while they move. Most notibly when there's white text on black background. I don't know many of you know it, but it's like applying the "inner shadow" filter to the fonts in photoshop.
I made a video to demonstrate that: http://www.youtube.com/watch?v=VVRTmsr6Ppg
Hopefully you can see the effect on the text, but it's very noticable that the lines between the items disappear while scrolling.
While on a grey background, text appears yellowish while scrolling.
I get a similar effect when I scroll through pictures.
Other than that, the screen is perfectly fine. I have a Neo V here with the same rom and kernel and there is nothing like that.
Or is this just normal screen behaviour I have to get used to?
What rom are you on?
Sent from my LT15i using birds.
if you look clearly at the screen, it is not getting darker! just the lines between the selectable touch fields are getting darker. dont know why but this problem is on all roms i have tested. it happens at small text and very small lines (1-2 pixel lines i think)
@TheHaso
Super Jelly Bean, Slim Bean, Ultimate HD.. It doesn't seem to matter.
@om22
So you think this is a software issue?
I noticed when I scroll through small turqoise text, it clearly gets darker and shifts into a more blue-ish tone.

no i think this is normal on tn-panel lcd screens (our arc/s). just a dark blurring effect i think.
If you want to get some information about TN displays vs IPS etc just follow the link:
http://en.wikipedia.org/wiki/Liquid_crystal_display#Twisted_nematic_.28TN.29
it's normal. only the lines get darker and not the text. this is how android makes it. try to increase the brightness and you will see that the lines gets a little darker.
But this effect does not happen at all on the Neo V.
And of course the text is getting darker, too. As I said, on black background a turquoise text shifts to blue while scrolling.

maybe because the neo v has built in another display? Our display also is very blurry in my opinion (high response time)
So i just picked up a G3 today and there's one thing that is bothering me.
All the outlines of icons / text seem to have a minuscule but detectable contrasting outline around them. It's hard to describe and kind of nitpicking, but my eyes do see it especially with text overlayed on a color or image background. It's almost like a tiny oversharpening effect and I've never seen it on other phones before. What is this? Is it due the layout of the subpixels? Also I noticed the color balance is somewhat yellowish. Is there a way to fix these problems? perhaps through custom roms? Would scaling down the resolution to 1080p make a difference.
Detailed example: I put my new G3 and Asus zenfone 2 side by side, and looked at their chrome icons (the exact same icons) through a magnifying glass. On the zenfone's display the line separating green and red in the icon transitions smoothly and normally- from green to red. But sure enough, on the G3, the magnifying glass reveals a tiny whitish line between the green and red areas! Therefore the change in color does not transition smoothly, which is what my eyes are picking up on. How to fix this problem?
If this is just inherent to the display itself I may consider picking up a Oneplus X instead, as it is somewhat irritating for my eyes especially when reading text.
This phone has a problem with oversharpening most custom roms have it fixed a lot of people complained about it u can reduce screen to 1080 but then u take away from the beuty of the screen if u decide to keep it root it then use a cust rom and itll be all good
If u have custom recovery then u can flash oversharpning fix mod.

Lying in bed last night I turned on Night Mode. I noticed when I pulled down the notification shade, the top portion was still dimly back lit, so I could see the camera cutout and the edges of the screen, no matter how much I dim the backlight.
Well tonight I fired up my Note 9, put it on Night Mode and pulled down the notification shade, and no matter how bright or dim I have the screen, the top part is BLACK. no light. You can't see where the screen ends and the frame begins.
This isn't a huge deal except for battery savings. When an AMOLED screen is true black, those prices shut off. But since the night mode on the N10+ isn't true black those pixels are still lit up and using power.
When viewing video in Netflix or YouTube the black bars are truly black, so I know the screen is capable showing true blacks, I'm just not sure why Sammy changed Night mode so it's no longer truly black.
I have just experienced the same thing. I have a note 9 as well to compare. I'm actually deeply disappointed. I also noticed screen mode only has 2 options... vivid and natural. Where as note 9 has 4 screen modes. I'm trying to figure things out to see if I can get it to be true black.
It's probably normal since it's a night mode and not a black mode ; in which you wouldn't it to make your screen showing heavy contrasted differences that actually made more eye fatigue than the light one.
Maybe I'll finally like this mode on this new phone.

No I understand it's a "Night mode" but I'm comparing it to the Note 9 and Note 8 Night mode where it became a true black. And I ran it in Night mode almost 24/7 for some battery savings as well. Well that doesn't work if Night Mode is just a dark grey rather than a true black.
And I'm not sure how true black and contrast made for more eye fatigue? Have you never watched a 4K movie? The whole point of high def is high contrast with true deep blacks, bright whites, and bright colors.
I also noticed on the quick access home screen in Samsung Browser on dark mode, it's not longer a true black. Now if you turn on High Contrast mode in the browser settings, then the background is a true black, so that panel is capable of turning off the pixels and going true black. This means it was an obvious design choice.

Dark VS black doesn't make much difference battery wise on OLED screens (let me just find the test back and I'll update my post)
Because the notification panel and anywhere else that it matters contains mostly texts and it produce visual retina persistence (not sure if I translated well), plus it's more annoying to read and and eyes accommodate less than in light mode where everything is light too.
There's nothing to do with movies since it's dynamic and constantly changing from a lot of different colours while texts are more static (but going from dark to light scene still hurts)
I agree that it's absolutely a design choice, but in my opinion for the better.

I gotcha. Makes sense. I'd like to see some tests on black vs dark. I had always heard and though the battery savings was due to the pixels shutting off. It's why the AOD is black and not just dark.
Buts also weird. I'm replying to this direct from the Gmail notification of your reply. So it opened up the webpage in the webview. Well the top bar above the page that says reply to topic and has had the Gmail overflow button is true black. But the status bar right above it is dark grey.
I guess what bugs me most is it makes the camera cutout stick out, even in the dark. Because I look up an I see a true black for on a dark charcoal background. And I can see the screen edges. I preferred on the Note 9 where it all just blended away with the true black.
But yet, when I watch a movie, the status bar DOES turn off completely and you can't see the camera cutout. Just can't figure out the inconsistency.

It may be because apps got their own night mode colour settings embedded, while all One UI apps got theirs which are different.
Like, if for Google night mode is all black, their apps will just check about system UI night mode trigger and of its on, apply their own settings.
I can only find that reason for it to be such inconsistent.

I totally understand and agree ! Especially when you like what Samsung did with their UI
In an other hand, there's some third party theme that may be of use to have a black theme : https://forum.xda-developers.com/s10-plus/themes/theme-anxious-t3921645
I don't know if it's working for the Note 10 yet but I think it's just a matter of time before it do

I just use a theme that's mostly black everywhere. No need for night mode..
One UI notification shade isn't actually black for any of the devices on the One UI. I had an S8+ before this and it looked black but if you take a screenshot and measure the color value, you'll see that it's not black. You can do the same thing on your Note 9. Take a screenshot and extract the color value. Or take a screenshot and then transfer that screenshot to the Note 10 and view it on the Note 10. I guarantee that the Note 9 screenshot of the notification shade will look like the Note 10 notification shade. Black will cause AMOLED smearing which isn't good look.

So I tried this. Set my Note 9 to Night Mode and took a screen shot. Sent it to my N10+. Guess what? The notification shade in my Note 9 screen shot is pure black when viewed on my N10+ screen.
So I did the opposite. Took a screen shot of N10+ notification shade and sent it to my Note 9, and it appears dark grey.
So I'm not saying you're WRONG, but this is proof that the notification shade on Night Mode on the Note 9 (and the Note 8) was SIGNIFICANTLY darker than the N10+. If they aren't true black, then they are so close at to be indistinguishable from it, whereas the N10+ is definitely lighter than black.
I also just used an app to do a color value sample on my screenshots. Note 9 notification shade is #00000. I believe that is true black?
See my attached screenshots. War Machine is Note 9 (The one with the true black notification shade) and the Darth Vader is the Note 10+ (the one with the dark grey notification shade)
To see what I'm talking about, you may need to turn brightness up on your phone or go in a dark room.
Screenshots of color picker showing Note 9 notification shade is #00000 (true black) and Note 10+ is #080808 (not true black).

I tried this. The notification shade was still dark grey, not black.
Samsung doesn't use black on the N10, it's that simple. They use a form of grey that's fairly close to pure black, however. The avg person probably uses white themes, so I doubt many will take notice.

Write back when you find a solution to make samsung browser black.cheers.
As Nastrahl pointed out it the pixels don't need to be completely off to save a lot of power. I was going for total black but since I adjust brightness manually a little bit of tint to the black looks nicer and makes it easier to gauge the brightness.
You can use the Good lock app Quickstar to make the pull down notification panel any color or darkness level you want. Mine is almost black with a hint of forest green.
My wallpaper is even darker with the same green tint.
When the brightness is too high the wallpaper's green tint is noticeable otherwise it looks black.
Hello, I'm facing a sort of problem. When I look at the locked screen it has a calibration, but when I drop down the quick toggle or I unlock the screen it turns a little bit more yellowish. I don't think it's hardware related but could someone give me an explanation?
I think it's because of the FP sensor. To improve the recognition maybe.
Or it is a bug like the dark theme not being dark in some apps, Chrome, YouTube, Shelf. Top of the screen is less dark, like a little bit green. Not a hardware issue though, settings and built in apps ark dark (Dialler, Messages). I think it is something with the theme settings.
It's all normal. The lockscreen has this colder/blueish tone, like a filter, which goes away after unlocking. Nothing to worry about, not a bug or a defect. Just the way it's designed to work.

I don't think so.
With every app that request fingerprint authentication the color of the screen changes.
It must be something related to improve fingerprint accuracy
I am not talking about the screen with FP scanner active. Just check the dark themed Chrome, Shelf, YT. Especially on the dimmed screen. Upper part is a little greenish. Cannot make a screenshot as it looks ok on it. It has to be sth with theme, as on some apps (dialler, messages, settings) the whole screen is dark (black).
Something like this:

Yep, and it looks like software issue to me.

As you can see, app is a little green, but quick settings are black when dragged down. Screen is fine, I believe.

Thats because green tint is only visible on certain brightness levels at grey background. No problem on black background
The issue related to the lock screen is present any time the through screen fingerprint camera activates. You will also notice it if you have face unlock active in low light and the screen lights up to assist the front camera in recognizing you. Color spectrum is super important to cameras when they are recognizing things on our skin.

That apps are not black, are grey. "Dark mode" does not mean "black".
In other way, all amoled panels have (or can have) this kind of behaviours at very low bright level and certain colours (especially grey).
Particularly, I do not see that effect in mine or I just cannot see it.
If you think that is a defect or problem, why not open a repair request to OnePlus?
Is image persistence normal for S20's screen or OLED screens in general?
For example, playing a bright video game with black aspect ratio bars, leaves a lasting persistent image, where on dark pastel backgrounds you can clearly see where bars and game were.
Or writing a long article, leaves remnants of Android's nav. buttons, Chrome's address bar, and even keyboard visible, when tested on dark pastel backgrounds.
These persistent images gradually disappear, but it takes a long time to disappear completely. Do you experience something similar to this?
Thanks.
Scroll down for testing methods, post #5. Start by opening dark gray image, view full image, zoom in, do you see discoloration?
Image retention (persistence) is a somewhat common issue with all OLED. That said you shouldn't be experiencing it unless your constantly rocking your screen at 100% brightness, or near there, for hours on end.
I found this cNet article which explains it really well.

The Galaxy S7 and S8 had issues with Screen Burn which Samsung improved going forward from the S9. If the ghost images gradually disappear it isn't Screen Burn which causes permanent discoloration. If under warranty you may wish to get the device replaced, it doesn't seem the problem will correct itself over time. The other options I would consider are uninstalling apps which you enabled just before the problem appeared or performing a Factory Reset.
if you're playing games and the background is constantly moving, then there should be little, or no image retention. However, if you are using Google Maps and high brightness and stationary for a long period of time (eg stuck in traffic) then I would consider some image retention could be present.
Thank you for your answers. Bold text for topics. Testing methods at the end of this reply.
Was not aware OLED screens' image retention is such a common issue, but I knew OLED screens are prone to burn-in, read about it online, and saw it on my relatives' older devices, so out of the box I turned on the dark mode and changed wallpaper to black.
I preferred regular Android's navigation buttons to gestures, because of ergonomics, due to phones center of mass (wish it was more bottom heavy), when using with one hand, balancing phone while performing gestures always feels like I'm about to drop the phone, I also find gestures to be slower, simple tap vs sliding your finger. And on top of that, I have carpal tunnel syndrome, so it's much easier to simply reach and tap. But now I started using gestures, as a burn-in preventative measure.
By the way, having Chrome open for around 20 minutes, and quickly switching to Display Tester's BurnIn detection, I can already distinguish Chrome's address bar section, and clearly see tab switcher button. This will gradually disappear, but the fact that afterimage appears so quickly and remains for so long is concerning, since I feel such image retention might indicate my display may be prone to burn-in, but of course, I don't know this for sure, just my uneducated guess.
Having dark mode keyboard open for around an hour, and I can see remnants of it even on grey backgrounds of folders.
Back to reply..
I never use my screen at full brightness, it's always set to somewhere around 50%, and as I said earlier, image retention starts to occurs in a matter of minutes. Images do gradually disappear, but it takes a long time, and when I use screen for hours with static elements, it felt like it took awfully long time to disappear, but to determine how long exactly it takes for them to appear and disappear, I need to do more thorough testing.
Yes, when playing games, indeed, a lot of things are moving, except for Heads-up Display, but I first noticed this image retention issue playing an older video game called "Super Cat Bros". That game is not optimized for such wide-screen phones as S20, so on each side you have a black bar, display is split into 3 sections - bar-game-bar. That game is very colorful and has lots of solid colors, so after I finished playing, in dark user interface backgrounds I noticed discoloration, later looking at solid color backgrounds l noticed clearly where each section was, so bar-game-bar. Because sides of a display were turned off, and all action happened in the middle, you can clearly see which part of the screen was the most active.
This is why I'm coming to conclusion, that dark mode alone is still only a small part in burn-in prevention, you should blackout everything, including websites (I remember firefox had plug-in like that, capable of replacing background and font colors), switch to a dim keyboard preferably without visible keys with orange-red colored font, download oled friendly icon packs, watch movies cropped in, so you're not left with permanent discoloration in place of "black bars", and play games full-screen, only then wear will be uniform. Seems like too much work. I wish micro-led displays would become widespread sooner.
I don't think factory reset or uninstalling apps will help, because it appears to be not software related.
At least not software user can update, such as display's firmware, but I don't know for sure just how independent display is from other phone's guts. Even then, I don't think firmware can fix this.
The phone is under warranty, since it's new, used for a few moths, and unmodified, but sadly is probably not an option, because in my country, gaslighting customers is fairly common. Service center will probably take it away for a few weeks, then return it scratched up, and say they didn't find any issue. So unless it's a serious burn-in, that's visible always and on every background, it'll be extremely difficult to make a return, and even then they'll probably tell it's normal wear, but then at least you can without explaining too much contact consumer protection and show them the problem.
Software used for discovery and testing:
• Super Cat Bros (video game)
https://play.google.com/store/apps/details?id=com.FDGEntertainment.SuperCatBros.gp
Play it for an hour (or more) and then test on solid darker pastel colors, do you see discoloration? Report for how long you played and how long discoloration was visible. Do not reopen game when retesting discoloration, because it may appear permanent. I know some people are not good at seeing minute differences in shades, but at first it should be very obvious which parts were black bars and part where game ran.
• Display Tester (app)
https://play.google.com/store/apps/details?id=com.gombosdev.displaytester
Very good display tester, free, lots of features and tests, and works on wide-screen displays, enable "use immersive mode if possible" in the settings. I think default color in BurnIn tester is very good at revealing discoloration, but you can play with sliders, just remember position which reveals discoloration the best.
• I'll also attach solid color image, which works for revealing discoloration.
And another dark gray image, which also helps reveal discoloration, use in dark room at around 50% screen brightness (play around), no matter how much you zoom in or out, it appears like screen has gradient, notifications bar icons are also visible, not sure if it's temporary or a permanent discoloration. I recommend opening these images with a gallery app, set to full screen, or simply pinch to zoom, and tap screen one time to hide gallery's UI elements. Tilt phone left and right, move towards and away from yourself, do you see discoloration?
You can also open them up with browser, and examine your screen, but I found you can't hide all UI elements, so better use gallery or other image viewer.
