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.
Hi all,
So I've had my Smart Watch 3 for a while now and overall it's great. There's just one thing that's doing my head in... Any screen that uses grey as a background displays in brown... It's not nice at all. True blacks are fine, but any shade of grey is looking awful...
Here's a screenshot from the device and a photo of the same screen:
I can't post external images so now I can't show my problem... Is there another way of showing my problem?
Well, to show the problem, you could link to an image on Google docs or something. As for fixing it, that is a tall order.
It's a tradeoff of the Trans reflective screen. I'll take being able to see the screen without Backlight.
Indeed.
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.

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:

On picture we could clearly see green tint defect
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.
