Set wallpaper to black or go to a pure black screen with no icons on it. Bring up the "recent apps" and clear it out so that the overlay is blank. I notice heavy banding when the app is brought up over a pure black screen. Anyone else notice this?
it's hard to notice in a lighted room. go into a very dark room and you should see what I am talking about.
I've noticed this on transparencies. Could be a low quality image they used. Google has been known to limit the colors available to specific apps. Gallery and the Browser usually display crappy gradients. Perhaps this is another form of lowering the image quality so it loads faster.
As far as what your talking about, yes I can replicate it. Horizontal "sections" about equal distance apart. Hardly noticeable. I have to turn the lights off to really see it.
As long as the screen looks amazing when I'm using it and not in a dark room at weird brightnesses, I'm happy. This screen is super vibrant and bright. Who cares about a little banding on an almost black transparency that is requires a pitch black room to see.
This is apparently NOT a problem. However, I would like to have some color fix on this.
I don't know if anyone knows what I meant
The One X screen compares to S3 or any other phone side by side, the one x had a slight warmer color tone, in other words, it's kinda yellowish.
it's truely visible on white screen.
I find this very disturbing, is there a way to fix this? I prefer a more natural and realistic color tone.
If you're gonna recommend an color fix app, can you tell me the input for primary color values to correctly fix it? I'm too lazy to fix it little by little lol.

It is going to be a colour fix app, but everybody has their own settings my cooler temp colour may be to warm for you or to cold. So you have to fiddle with it ti find your own settings that you like.
Give this one a try and see how it works: My Settings are alpha set to 8 and blue set to around 80ish or so.

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?

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)
Greetings,
I just purchased my Samsung Galaxy Nexus but I noticed after some months of use, some strange blue lines that appears only on blue, grey or specially light colors as white backgrounds. I am very upset since I bought this good cellphone but noticed the screen issue. People told me that those blue lines where just a software problem but the thing is that I recently upgraded from 4.2 JellyBean to 4.4 KitKat and those annoying lines still appear on specific backgrounds. I forgot to mention that those blue lines appear in full-screen mode where the notification and the digital buttons bar are when they hide while in that mode, for example: when playing games, visualizing text or images, watching videos on Youtube (all of it in full-screen mode). You got the idea, right? Its like when the full-screen mode is on and the functional bars of the Nexus fade, it is supposed to be the same color as the whole background, but not; it appears like a tone of blue instead. This has nothing to do with the camera by the way.
I now think that the issue is related to some problem with the screen and hardware. I don't really want to replace the whole screen with a new one since Nexus screens are very expensive. I can't claim a warranty as well.
So, the questions are:
¿Does anybody have or have had the exact or similar issue as me?
¿Can someone please explain me what's going on and give me a solution?
I will leave few images bellow where the blue line is more visible:
1st Picture: When Youtube is loading the video, the notification and digital-button bar are gonna fade to play the video in full-screen mode.
2nd Picture: While the video is playing in full-screen mode, on the edge of the screen where previously was the notification bar, the blue line appeared, you can see it easily.
3rd picture: While reading any type of text or viewing a picture in full-screen mode where the notification and digital-buttons bar fade, the blue line appears again and its very easy to see it.
4th Image: This case is different, on a background with dark blue and black colors, there is some blue tint effect that is slightly notorious, the picture taken from the camera doesn't show it very well.

Yeah dude, it really sucks and its kinda annoying when watching videos or reading something. Google should make something about it on future cellphones!
If you fix it or at least reduce the blue shadow a little please notice me, I am very upset about it. :crying:
My „blue lines” appeared after I dropped the phone
Seems like standard Galaxy Nexus AMOLED burn-in. Try something like this but dont expect too much.
Screen burn in. I have it too. There's no fixing it on an AMOLED display without replacing the screen. This is my first and last device I will buy with AMOLED.
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.
