*edit: added a video on youtube so you can better see it in action without having to read my ridiculously long and rambling explanation below. I tried clearing gallery app data, and that made the yellow tint appear more slowly, but didn't go away.
==========
I just started to get this weird somewhat random yellow tint in the google gallery app... it just started a few minutes ago. I've never had any problems with it before. I've had the phone for 4 weeks. This is just bizzarre!!! I've always used the stock gallery app to view photos and attach them to emails etc... no new apps installed today... however I was playing around with nova launcher and widgetsoid, but not really messing with system settings or anything...
Sometimes when swiping through photos is a gallery folder, they will all be yellowish, but when I swipe the first photo to the left (i.e. no photos to the left of the first, so you get the blue gradient telling you that you are at the end), the yellow tint will disappear.
When the list of thumbnail gallery folders are first loading, as the screen refreshes, the yellow tint is not there at first but then it appears... sometimes in different configurations... some folder thumbnails not yellowed, and others are, and some only have the folder name text yellowed.
Stock 4.0.2, rooted.
I have read some threads about yellow tints to the screen but this is completely different, it seems. As it selectively chooses content to be yellow...
Thumbnails attached... one photo in the normal and yellow screen version, and 3 screenshots of my gallery app main folder with far left normal, and then two different yellow versions of the screen...
also, swiping left and right in a gallery folder has different yellowing effects... swiping left (to scroll right) leaves the lower right corner folder un-yellowed, swiping right (to scroll left) leaves the lower left corner folder thumbnail un-yellowed... --- see attached photo comparison.. and these are screenshots not photos of the phone, so maybe that says something about what is going on maybe, that the screenshot captures the yellow tint..
Any ideas??? help!?!?!
I'd like to try and delete the gallery app and reinstall it, but not sure how best to go about that... it really seems like a software issue, and isolated to the gallery app.
PS: sorry if I broke any forum rules, but I posted a thread on phandroid too, to see if anyone there has any ideas too...
sorry to bump... I think this is an interesting and unique issue... anyone having something similar or ideas on how to approach solving?
- i've tried playing with developer and screen settings, deleting gallery app cache, killing all background processes, to no avail...
*watch the video to see the issue in action...
try a factory reset, if it still does it then it a bad phone and contact samsung
[solved] chainfire3d nightmode issue
So the color of the tint was 'amber'; this was my choice for chainfire3d nightmode, which was enabled and "on". However, nightmode seems to not work on the stock rom, except that it affects the gallery app in this way. I changed the nightmode color to blue and lo and behold... the gallery tinting was blue!!
So I turned off nightmode from within the chainfire3d app and the issue seems to be gone.
Nightmode must have been enable sometime between the last time I used the gallery and then to when I first noticed the tinting.
I'm considering uninstalling chainfire3d driver, at least until I get a custom rom... but you know what they say... if it aint broke dont fix it!
Hope this helps anyone else, if they start experiencing the issue...
Have the same issue on CM9 Alpha 0.5 on HP Touchpad.
CF.Lumen and Night Mode does not work. It just make some thumbnails red in the Gallery App...
...this was intended to go on the chainfire app thread...
Hi everyone, I would like to know if we can come together to a conclusion of why the gallery app is so laggy! Its very striking that the gallery has serious problems while swiping through pictures or pitch to zoom, while in the Google+ app or the screenshots in the market the transitions are really smooth.
Any suggestion of why this is the case? Bad programming?
What gallery app are you guys using? I've tried quickpick but I don't like it either.
Gallery lag
I've noticed the lag too. The size of the photo doesn't matter. It lags even with small images.
I've found 3 more causes for lag:
1) The glow of the soft keys. If you have a custom rom and disable the glow of the buttons, the Home screen transitions when pressing a softkey will become smooth.
2) If you are in the Play Store and you are browsing an app with a long name (like PVSTAR+ (YouTube Music Player)) the scrolling would become stuttery.
3) System messages. If you get a system message (like "..." has been granted Superuser permission) everything would start to lag while the message lasts.
Those are really small things and I hope Google would fix them in a future update.
I figured out that here would be the best place to ask.
I am struggling with the crappy fullscreen mode in landscape - the area around the camera is always either black or white. Did some tests - the most of the apps to not utilize the screen, where only the notification bar (being on the long side in landscape mode) does. Strangely enough, Google Maps and Google Translate DO utilize the whole screen in landscape mode, where as hangouts or gmail don't. This is with setting for full screen apps.
Did some reading and it seems like there are 2 ways - either the app forces the fullscreen or the OEMs. Did some tests with my own app at it looks like the only way for the app to appear fullscreen is to be allowed in the app. Is that so?
Does Gmail also have this blank area on other phones?
As you say, some apps use the full area, others don't, I believe the issue resides in the apps, not the device
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.
Is anyone seeing some weird behaviour on their Fold 3 where apps' backgrounds turn grey instead of black? For example, in Youtube, Flipboard and Google News. I'm using dark mode and seeing this behavious consistently. If I quit the app and re-start, it reverts to all black.
Edit: samples attached. I think I've narrowed it down to navigating with a bluetooth keyboard (why on earth that causes this...?
Try clearing the system cache.
