Ghosting on screen - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Hey all,
I was looking at my phone, the Samsung Galaxy S20 Ultra, and I noticed some kind of ghosting or burn in or something. It looks like the image of icons that were on the screen, and are burned in. Any ideas? I included a pic I hope will explain better.

Running it in sunlight and/or brightness over 50%?
The pixels are wearing out from use. Blues go first, reds last generally from wear.
Use manual brightness control. Avoid use in direct sunlight. Keep brightness no higher than needs. Use dark mode and dark wallpapers.
Rotate widgets and icons.
My homepage and settings tweaked to minimize premature display wear.
Test it and see what you got:

Thanks for the insight. Is there any way to fix what has already happened?

Negative. It's a normal wear thing.
It's possible the manufacturing quality of that display wasn't good. See if you can badger Samsung into a warranty repair or reduced repair price. There have been a lot of issues across the board with variable refresh rate displays. One reason I stayed with the N10+.
Using dark mode and dark wallpapers will make less noticeable.
In the future take steps to prevent this with a new display. Yeah they get very bright but organic LEDs aren't as robust as their thicker non organic counterparts. Limit max or near max brightness to seconds not minutes. Avoid using in sunlight whenever possible. A 50% max limit except for some vids is sensible and helps a lot. Use lower levels in dimmer light, don't burn your retinas or display out.

[Q] How to read the screen in daylight?

I'm new to this phone and new to smartphones.
The reviews of the SGS2 rave about the bright, readable screen - even outdoors. But, I can't even tell if it is turned on without ducking back inside! The screen appears black to me.
I'm panicking because I invested in the SGS2 (full purchase price!) largely as a navigation aid for bicycle touring. I need to be able pick out fine detail on a Google Earth image. It's beautiful stuff indoors, but under the sun...
So, please assume nothing and give me all your tips, settings and strategies - basic and otherwise - on using the phone in bright sunlight. Thanks,
Stan
what is your screen brightness at? I've had mine set at auto brightness and the phone does a pretty good job of adjusting the brightness up when i move into sunlight so that the screen is still readable.
if you're having a hard time seeing the screen outside, try turning the brightness up. you might have it set too low
It definitely should not look completely black when outdoors. Either there is something wrong with the screen or with your eyes. Try setting it to max brightness and see if there is any difference.
if you have it in auto, it would automatically adjust to match the lighting conditions
SMAOLED screens are super good in directly sunlight you can still read bright and crisp even when the sun is cooking your head at 35c outdoors in a hellish summer shine

[Q] Color off when display dim?

Anyone else notice this?
When my Lumia 900 display backlight is set on low, the colors seem... off. However, when its on high, they look normal.
I did not have any color issues like this with my old Focus.
I've noticed this to somewhat,I'm sure it has something to do with the amoled screen, I however have been having issues with WiFi,I never seem to get a good solid connection even when I'm in the same room as the router, sometimes itll work fine,but it acts as if it cuts in and out

Thats why I mentioned I had a Focus, I believe it has the same type of screen. Minus the Nokia ClearBlack of course.

I noticed this too. The screen seemed dingy and grainy. From what I've read, it's the nature of AMOLED technology and I think that color temperature scales more with the brightness setting compared to IPS handsets.
I also had a theory that the ClearBlack layer between the glass and the display may make the display grainier, as I've read it scatters the light or does something to make it less reflective but hinders the overall display at lower brightness.

My lockscreen image's colors look much much darker unless I put the screen brightness at mid or high.
Does your issue go away if you turn the brightness up?

HD Super AMOLED Eyestrain?

Does anyone else experience eyestrain with devices that have the HD Super Amoled screen?
I notice after about 10 - 15 mins of use, I get dizzy and my eyes hurt like they are being crossed or something when using the galaxy s3 or galaxy note, my old galaxy s2 skyrocket doesn't bother me though....
I've tried to turn the brightness down all the way, using the device at different distance to no avail.
Any possible solutions to remedy this? or am I going to have to sell my new S3 like I did my galaxy note? :/
depends on 2 very important factors...
1- how much cheese I've smoked
2- what was the question again?

I've actually noticed a decrease in eye strain coming from an LCD screen on my atrix. LCD screens are constantly flashing, and the screen on my galaxy s3 is super clear for me almost no eye strain. Its probably personal preference though.

I've actually experienced the opposite as my first android device was an atrix....
I think it may have something to do with the 1200 x 800 resolution on such a small screen because If I turn up the resolution on my PC HD monitor to something like 1600 x 1200 for example, my eyes start to hurt.
I was actually going to post a new great until I saw this. I came from retina displays and my eyes are sore after I look at the screen for over 10 minutes on my GS3. Kinda concerning!! Might have to switch back to an apple product. I was getting use to droid too. :-/
its because of the screen size/pixels. Your eyes still needs to be adjusted to the new screen lol... obv
Yes!
I got vertigo/migraines about a month after getting my S3. I had a number of medical tests to see what was causing it - but even after new glasses I've narrowed it down to the S3 display being too strong for my eyes. I'm going to sell mine and get a replacement with a duller screen.
Try this...
Try changing the Screen Mode to 'Natural' or 'Movie". Helped a bit.
I also immidiately noticed eye fatique after getting Galaxy s3, particularly in my right eye. It started only getting worse, and coincidently only when I was using Galaxy. Other lcd devices such as older 3gs never bothered me at all. Surpisingly majority of reviews call the display stunning quality, but its pretty dim, practically unusable outside and colors are unnaturally oversaturated, all of which didnt bother me that much as long as my eyes wouldnt hurt so much. I started reading more about specs in Super amoled technology, but nothing pointed out to potensial issues, than I googled galaxy s3 refresh rate, and the first video from the search result comparing s3 to the iphone, provided a major clue. The poor quality camera was picking up horrible flickering from galaxy, but iphone screen didnt flicker at all. It instantly brought me back to old CRT days, and I also remember getting dizzy from such displays running at low refresh rates of 60mhz. Back than bumping up refresh rate to 75mhz conciderably dicreased eye strain. I took the video to the store, sales person was suprised that I was returning such popular product, but its been a day since my exchange for another brand and eye strain is gone. The issue maybe overlooked as it affects low percentage of people, but if you have sensitive vision, than you'd be much better off with non hd amoled technology
Could it be the brightness?
I'm sure your not holding it against your nose while watchin you tube, but maybe its the overall brightness of the screen thats getting to you? I use a powersaver app that has a black screen filter that dims it out a good little bit, maybe something like that could help, or a matte finish screen protector...the anti glare ones I think.
Use the "Screen Filter" for use at nights.
Set brightness to 0, and enable filter. I set mine at 48.6% and 36.9% (created two widgets with these percentages) and use either as needed.
Set your brightness lower. It's the brightness of your screen. I have the same problem before turning down the screen

Keep phone at safe distance from face. Try a dark theme or inverted apps, or both they will most likely reduce eyestrain as well as save battery.

Seems ok to me with brightness anywhere from dimmest to 50%.
hmm, can't say I've experienced any strain.
The cm10 rom is extremely bright too, at half, I started getting headaches but on stock, I can state at near brightest all day.

Hi all,
There are a lot of users who feel uncomfortable with AMOLED displays (not all of them, for example sgs2 is not affected). They can struggle with head ache and eye strain. You can google "galaxy s3 eye strain" for example or watch how AMOLED blinks through photo/video camera (there are tons of youtube videos). This effect apperars only when screen brightness is not at maximum level. The nature of that is the mechanism used for brightness control. Instead of forcing the pixels to glow at less brightness they force them to blink very fast. The faster pixel blinks - the brighter it seems to the user. The downside of this is that the whole screen blinks as an old CRT monitor which causes this negative effect.
I found an app which could help us to workaround this issue. I filed a feature request. So if you are interested you can add yourself to wathcher list and post a comment here - https://bitbucket.org/VitoCassisi/lux/issue/38/lux-auto-brightness-feature-request-for
This should not take a lot of time since you can authorise there with your google/facebook/twitter or other account.
Wow! I switched the screen to "natural", the problem with oversaturared, too rich colors was solved. I had to keep the brightness low so color pictures aren't too bright, but this made reading text on white backround unpleasant. Of course now I have to find new brightness levels (what brightness levels do you guys use for day and night?)
PS: Samsung has been doing similar tricks with the colors in their TVs. Some series 6 TVs made the picture look like it was from a heat sensor in dynsmic mode, and this was their default mode.
PPS: Mobile screens suck. LCDs have washed out blacks which strains the eyes, and AMOLEDs don't care about correct colors which makes you duzzy.
S3 screen flickers!

You are absolutely right. S3 screen flickers a lot. Try to move it quickly in front of your eyes, move your eyest when looking at it, or move your finger fast in front of the screen. I certainly do notice it.
What other phones have better displays? Sony? HTC?
I have a solution to resolve galaxy S3 scren flickering: set brightness to max in settings, install an app like "Screen Filter" (one with black-white rectangle) and decrease brightness there, in the app.
Flickering gone!

Most of phone LCD screens are not affected by flicker. Even some amoled displays too. For example old HTC Legend and galaxy S2.
Galaxy note 3, 4, Galaxy s4, 5 are also affected. I strongly recommend you not to buy any new samsung phones equipped with AMOLED screens.
Now with this https://play.google.com/store/apps/details?id=com.vito.lux software you can get rid of screen flickering issue. Automatic brightness adjust will also work.

Considering a return because of the ambient screen :(

It's a shame really, since I love EVERYTHING else about this watch - good price, snappy processor, GPS, WiFi (not even sure what that will bring eventually), NFC.
But with this thing serving primarily as a watch on my wrist, I just can't stand the ambient screen. From pretty much any angle it is a low-contrast, mustard-y yellow.
I'm looking at the LG R watch now. It's $50 more, and is missing a bunch of features, but the screen is GREAT. :'-(
I really wanted to like this watch! Please XDA, talk me into keeping it!!

The LG P-OLED screen can burn in... Otherwise I possibly had bought it aswell.
I love the sw3 and especially the ambient mode screen and GPS. Its looks like a compromise between a e-ink and LCD..
But maybe it's a kind of different tastes.

Good point about the burn-in. I just searched over on the LG R watch forums and there's some horror stories of burn-in after just a week. :-o That may be a deal-breaker for me.
Hah! You may have talked me into staying on SW3 just as I requested - thanks! :highfive:
It's a garbage screen on a first-gen looking product. I returned mine for the same reason.

I haven't gotten mine yet but have played with it in store. I wouldn't say it's garbage. Is it on par with other android wear devices? Probably not. However, just as another user stated above, its sort of a mix between e ink and color. It seems to be helping to deliver great battery life with it too. Also, with the update it seems you guys can turn off the feature of activating the screen arm movement. So with this screen you can leave it on always on mode and still be able to see the screen without killing battery. All the android wear devices are first gen tech, but the Sony SW 3 still offers so much more than any of the other watches. For that, I can certainly deal with the screen negatives. Even though it does offer positives so its not completely bad, therefore back to my point that I wouldn't call it garbage.
I like the screen...in my office or while outdoor, I can look at it at any time and almost any angle and can see the time w/o artifiially tilting my arm, or pressing a button. The screen is always on and I get easly 2 days...that is worth a lot to me. My 2 cents....
No matter how you look at it the pro's outweigh the con's.And if you can't live with then just return it and I'll keep mine.

Good point. It's a major flaw of OLED screen. SW3's transflective screen is the perfect choice for ambient mode. It's more readable in bright sunlight. Honestly, transflective LCD is born for outside activities.
I got my first SW3. The screen is too yellow with a small dark spot at the bottom of the screen. I returned it immediately and now the 2nd one is really good.
I disagree. Try taking your smartphone and let the sun shine on the screen (or a bright lamp) and lower the brightness. The whites and blacks will be very similar in color to the SW3's screen. I'm currently using the Odyssey watchface and sometimes it takes a while for the full watchface to turn on so I get the opportunity to seen the ambient screen with the backlight on. Whites are white on it. What I would like is for the ambient light sensor to turn on the backlight at minimal brightness in low light conditions.
my device is very white. It is of course no OLED screen that are over saturated mostly but i definetly see no yellow tint there on white (maybe a really tiny bit more yellowish but really nothing i notice at all in normal use).
And having the watch always on is such a huge + in my opinion. Yes you can't see the screen in low light situations. But honestly.
People are never happy. When the backlight would be always on some people would complain that the watch is always making light in the dark.
(which would annoy me probably more)
If you want correctly displayed colors you would need to calibrate your screens.
Who does that for home usage here?
It's definitely not first gen. I had first gen smartwatch from Sony, this one is ten times better
I would like the option for a low backlight on low light (current low backlight settings are too bright to begin with). I suppose that's what custom ROMs/root apps are for.
I like it on mine. The default faces are pretty bad on it in ambient mode, but I built ones for it on Facer that make it really easy to read.

I'm not sure if you had something like this in mind ( http://forum.xda-developers.com/showthread.php?p=57615301 ) ...but I'm using this app and it lets me lower the brightness down to where it's much more comfortable for using my watch in bed at night. The developer is letting us try it out for free until 12/21... but I went ahead and bought it for a buck from the Play Store.
Grown to love ambient mode, except for complete darkness I can read the watch fine.
I have a Gear Live, try to go out in the sun and read the time, this watch no problem.
I purchased Facer, made myself a digital watch face with huge numbers that makes the watch even more visible in direct sun

Agreed! I live in Florida (the sunshine state) and spend lots of time outdoors. Our days are long, it's almost always sunny, and the sun is INTENSE! I got this watch specifically because of this display. Try reading an OLED display outdoors in Florida sun. Even my Note4 with its high-brightness outdoor mode is barely readable. Yet my SW3 is clear as day, with or without the backlight. Yes, it definitely doesn't look as pretty indoors as the OLED screens, but for my use its perfect. Not like I'm watching movies on it or anything. I'm glad Sony decided to carry over the transflective tech from the SW2...it was a bold move but it's one of the things that sets this product apart. If you don't like it, there are plenty of competing products on the market.
I just wish there was a way to disable the backlight under any ambient light conditions, like my SW2. One of the firmware updates for the SW2 introduced a smarter backlight that stayed off, even when in use, when there was enough ambient light, like outdoors. While it makes no difference in appearance, it helps conserve battery.

Transflective screens are also installed on all Garmin outdoor standalone GPS: if you want a well readable screen on EVERY situation you need a transfective.... NOT a AMOLED.
Amoled is much contrasted and wonderful on artificial light or on low natural light, but is a pain during summer outdoor activity (and need maximum power consumption to be barely readable)

The transflective display is one of the big selling points of this watch if you ask me. It's visible in pretty much any light except very low. I don't have to turn the backlight on to see it (saves battery) and it's viewable in direct sunlight. This is a huge plus for anyone taking this thing out for runs or bike rides. I'm a long distance runner and use this watch exclusively for tracking and music, it works great!
The screen on the Sony Smartwatch 3 is the best, hands the fak down!! Always on and viewable, just as watch suppose to be.
Its comical sporting a watch thats turned off until you put it up in front of your grill to turn ON...gayness to the fullest.

Reddish and blurred tone in letters and screen images

Hello, I just bought an S20 + and instantly I have noticed that the image quality is a little strange, the letters especially on black backgrounds look like with a reddish outline not very noticeable but enough to bother me and some images in general are come as low quality. I came from using an A71 where everything looked correctly maybe that's why I notice the problem so much.
I was reading on forums where they say the S20 has various display issues, especially the ones made in Vietnam like mine. Others say that the reddish tone is due to the screen protector that comes pre applied. I would like to know if anyone else has noticed these details or if it is just a problem with the firmware that can be fixed later. Thank you. Sorry my bad English.
This may have something to do with display's subpixel layout and subpixel rendering, but the effect should be very subtle, not immediately apparent.
Tell us face-to-phone distance in centimeters when you start seeing the effect, display's settings such as brightness, resolution and refresh rate, where exactly are you seeing this (name of the app, dark mode on or off), font size, visible in darkness or in well lit environments as well?
Best thing to do, if possible, is to go to a local store that has S20+ on display, and compare, or if inside glass showcase, ask if they can turn it on and show it to you.
Also, that factory screen protector is known to be of not the highest quality.

Thanks for answer. I have managed to reduce the reddish effect by calibrating the screen because it was warm by default. The blurring effect of the letters decreases a bit when using it in 1440p..... but I have noticed that it may be a problem with my eyes because the same effect occurs when I look closely at my PC screen (10 centimeters), black text with reddish tint. I will try to go to a local store and compare with another s20+. As I mentioned it's little noticeable, maybe I have very demanding eyes.
I wont remove the factory protector for now, although I know the screen would look better without it.
My complaint about low quality monitors at work and with phones has been resolved with visit at the optician, and i dont mean to offend you here but seriously since i have glasses screen looks finally sharp again!
