No cure for burn in? - Samsung Galaxy S9+ Questions & Answers

On many LG devices, there is "kcal" settings to tune the display to eliminate screen burn.
Here's a good example:- https://forum.xda-developers.com/t/...ontrast-and-also-get-rid-of-ghosting.3653992/
I cannot find any alternative or anything similar on the S8 or S9 forums which is strange considering burn in is a big issue on our devices too.
My question is, why is there no similar cure, what am I missing?, Or have I not being look hard enough?
TIA

The OLED pixels are failing. The calibration and color accuracy as well. Since blue pixels die first any compensation be limited and you would lose color/gamma calibration. The blue pixel output is already near its max when new compared to the other pixel colors.
Red pixels generally have the longest lifespan. No way you can accurately color calibrate one of these display by eye.
Once an OLED display is degraded only a new display will really fix it.
The only thing you can do is reduce the wear by not using in direct sunlight. Use manual brightness control and keep below 50%. Use max brightness for seconds not minutes. Use dark mode and get rid of the notification icons at the top. Use dark wallpaper and red or darker icon packs. This N10+ has over 8k hours on it. No detectable display damage or degradation.

Limit exposure to sunlight and excessive temperatures including during storage.
A hot running phone is burning both the battery and display. Correct the cause of excessive power consumption.
OLEDs are very susceptible to water damage; keep water away from phones even if ip68 rated.
My N10+ AMOLED conservation management strategy. So far it remains in excellent condition even though it's been heavily used daily almost every day for 3 years. I slightly rotate the static homepage icons every month or so. Newer Samsung's incorporate pixel shifting as well.

[Q] anyone have slight horizontal banding on their optimus?

I can't see the banding all the time but when I do it's very annoying. I'm going to try and post some pics today. Is it normal or can I get it fixed?
No one at all has this problem or has heard of it?
what do you mean by banding? describe it properly
in my case specifically i can see faint gray horizontal lines going across the lcd on my phone about every quarter inch. it is especially noticeable on a white screen. i emailed the ebay seller and they stated that it was normal and i would not be able to return or exchange the phone since it was sold as new. i emailed LG about it and they said it would cost anywhere from $40-$100 if it was actually a flaw. like i said in the first post, i'm going to try and get some pictures up soon (hopefully in a couple hours after i get some sleep) to graphically show what i'm talking about.
DarkKnight62, if it helps in any way: I have observed this on my screen too. The faint gray lines made me believe text lines were burned in the LCD screen, but that would have been pretty much impossible, since I don't read that much on my phone. I can only see this effect when I use the screen as a flashlight - white background and 100% luminosity and it doesn't bother me at all.

even I read a lot on my phone but I keep the brightness lower than the lowest default. so I dont have this problem.
I think, It's due to surface dithering. See our phone is not 16m colors its 256k so the colors that are missing are to calculated and displayed and that's why the horizontal band if the we set no surface dithering (custom roms mik) the banding just vanishes but the quality of display is reduced. All the linear gradient colors are no more gradient.

I do have this gray lines horizontally and vertically if you see the phone far and carefully only in white background... when its near, the lines just dissapears to my eyes, (like if they get used to the display)
"gray horizontal lines going across the lcd on my phone about every quarter inch"
I don't think he is talking abouth the lines between pixels.
can you post a picture so we can understand what are you talking about?
@DarkKnight62 I had a same problem. If you are using francos kernel (and/or roms that have it integrated) it's more visible - very noticeable on wallpapers with smooth gradients. Try switching to stock or mik_os CM7 mod 6.5.4 stable (which is great)...
@soberspine This is example:

Screen color temps between units

Here's a side-by-side of two ATT GS2s on auto brightness showing the same application. The one on the left has a bluish/greenish tinge to the display, while the one on the right looks...I dunno...pinkish? Almost dirty by comparison, at least to my eyes, as it's much harder to read in low light settings. I thought at first it was the Helvetica vs stock font, but it's clearly the panel's lighting characteristics.

Here are the same phones again running the 'dead pixel test' from the Market, set to max brightness on the white screen color test.
The one on the right doesn't seem to be able to produce a true white.
Now, I get that there are different screen suppliers, and manufacturing variances among panel batches, but this whole thing has me a little disappointed at Samsung's QC. I would love to know what qualifies as a successful screen test, because the one on the right is a huge disappointment to my eyes. Just for the hell of it I compared both screens to my old Captivate, and to my surprise that had the most accurate color reproduction of the three.
How bout you guys - true whites on your screen? (try the gmail app, for example) Maybe I just got a bad batch?
The screen on my SGS2 has no colot tinge whatsoever. It's white and bright. I did however notice a bluish tint on my Infuse; which drove me crazy. I actually exchanged 3 Infuses because of a flaw in market where I got the "unable to download, insufficient memory on device". Each Infuse had a different tint, or brightness to the display. I switched to thw SGS2 and haven't looked back since.

Wow... big difference.... what the hell...
I thought this too about my SGSII when comparing it side-by-side with store units... Turned out for me the brightness was the same but another setting (adjust screen to save battery or something like that) was checked on my phone, making the screen look like crap on some colors, including making white look gray and yellow look bluish. Once I uchecked that box the display looked fine.
yeah I am anal about colors too. Being a photographer.
So I was looking for ways to improve the displays on my SGS2(now returned).
I have a Gretag i1-Pro spectrophotometer that I use for calibration and also matching color swatches. So I 'calibrated' my screen to the best of the available software. There is a program call 'Screen Adjuster' you guys can use to alter the RGB values. However gama will be off, and you can only calibrate EITHER high bias RGB or low bias RGB. There is no way to calibrate both.
Have you tried Supercurio screen tune? He just started making it but can probably help you out with colors and such.

QC and screen temperature were both big issues with the ISGS2 when it launched. There's a 100 page thread that's been talking about it since May. Five ISGS2's side-by-side all had from slight to wild differences in color temperature. Some of the ROMs also alter color temperature which makes it even more confusing. Cool/blue is what's intended to be normal and warm/yellow is the exception. The phone on the right in the pic looks like it has a warmer screen. I'd guess they changed either the screen or manufacturing process for the ASGS2 or you guys would have been freaking out by now.
P.S. - Samsung manufactures all their own displays and they all come from the same factories. So if there are differences it's QC or allowable deviation.

Outdoor visibility (max brightness)

Rate this thread to express how well you can see the Samsung Galaxy Note 10+'s display outdoors. In case you've been playing Minecraft for 18 months straight, you might not known how to get outside anymore. Well, find the door and walk through it. A higher rating indicates that it has very high maximum brightness and thus fantastic outdoor visibility in direct sunlight.
Then, drop a comment if you have anything to add!
For a phone of this stature and price, could have tossed in a better refresh rate.
I own this along with an iPhone 11 pro.
The iPhone 11 is much more visible outdoors.

No it's not lol. The note gets 300 Nits brighter
Among the brightest phones, according to the specs. And my experience with it has just confirmed it. I never felt the need to crank it up to max however, as there isn't a huge difference between setting brightness to 70% and to 100%, whether indoors or outdoors. I suppose the brightness increase is not really linear? In any case, more than satisfactory.

Try holding them side by side together on a sunny day with the Note set to auto brightness so you can get the max theoretical brightness.
It's night and day, no pun intended. The iPhone is hugely more visible.
Not only is the iPhone greatly more visible, but the Note's battery completely clonks out when the screen is bright while the iPhone just powers on.
I'm not Samsung bashing here. I've had every Note since the Note 2. Just stating what I see.
Well, some other factors may influence here, I use vivid screen mode with coolest tone settings and high performance mode which cranks brightness up 10% more, I have no iphone 11 to make a side by side comparison, but things may be different with the settings I mention, and about battery, well, a brighter screen of course will eat a lot more battery juice

Turn on vivid verses natural.
That said limit viewing in direct sunlight to seconds not minutes. I limit brightness to a max of 50% (some vids need higher). Used like this* the display will easily last many years and thousands of hours of SOT with no display degradation.
*use dark mode and what icons, wallpaper you use to extent battery and display life.

Google Ambient Display

Not sure if it's new but it popped up and I enabled it today.
Anyone know how efficient it is compared to OLED panel?

Ambient display on anything other than an OLED panel is waste of energy.
An OLED panel can choose to turn on only specific pixels and keep the other pixels totally off, thus saving energy.
Ambient display on OLED panels does exactly that. It merely lights up a few hundred pixels for ambient display and keeps others totally off, thus using very less power. This is the reason why OLED panels have deeper blacks. Because the pixels are kept off to depict black colour.
Our poco Panel on the other hand is a LCD display. LCD screens can either be fully on. Or fully off. This is because LCDs have a backlight to illuminate the screen as a whole as opposed to OLED panels where each LED pixel has its own light source.
Keeping the LCD screen on for such long times will drain away battery and might also affect its life. This is not bad only for the battery, but also the screen.
OLED panels barely use power while using Ambient Display. And regarding the screen, the clock keeps moving a few pixels from time to time to prevent screen burn in on an OLED panel.
In short, this is not even remotely efficient.
+1 what he said, plus your mobile will charge slowly because it has to keep whole display backlit.

It's a micro use of screen brightness, so don't affect the charging time.

I activated this feature too and it's good, only for when the cellphone it's charging, so it's ok.

Alldocube iPlay 50 Tablet (Android 12): Display output has greenish tint + artificial sharpening artifacts – How to fix?

Note that the described tinting effect is IMO, and based on my eagle eye and 30+ years experience in the field neither caused by the color of the backlight LEDs (as one would immediately think from seeing the snapshots; I know backlight color variations ... this clearly isn’t one), nor as someone presumed, the panel lamination glue.
Question to Android developers who are familiar with Display Color Profiles/CLUTs and output filters (if such exist):
Already owning an Alldocube kPad and iPlay 20s, which I'm highly satisfied with, I recently purchased 8 pcs. of Alldocube’s new iPlay 50 via AliExpress (excellent deal: each 2 pcs. for a total of USD 225 delivered). The hardware built quality is as with the previous models excellent, but the display on the iPlay 50 has a major problem:
When placing the iPlay 50 next to the excellent kPad and iPlay 20s one notices that
the colors are completely off and have a greenish tint
an artificial contrast enhancement/image sharpening effect is obviously applied, which adds an annoying and disturbing halo effect to detailed areas and edges where dark colors adjoins lighter color (e.g. black against medium grey).
Both effects are globally, so not limited to a specific app or screen area.
Unfortunately the effect is very difficult to capture in photos, attached below are my best efforts (the chinese comments are meant for Alldocube’s Customer Support, which isn't very supportive on this issue, although it would be in their best interest).
In my opinion it is not a hardware (LCD panel), but rather a software issue, thus should be easily fixable by their software engineers. Note that it is NOT POSSIBLE to correct these problems through Android’s Settings > Display > Contrast & Colors! The greenish tint remains, and so do the artifacts of the unwanted, unnecessary sharpening. Greenish tint also isn’t affected by Material You.
Any suggestions or ideas how to fix this? Because if I can’t fix it, I'll have to return those tablets, which would be real pity, as the tablet as such with its laminated 2.000*1.200px 10.4" IPS panel is an excellent bargain.

hello
i bought brand new one and its like yours i think that the lcd pannel are just bad quality
I have never seen a screen as bad as iPlay 50. I think it would be better if rooted to adjust the sharpness.
i forwarded this post to the seller, hopefully we get some update on it soon cuz i also experience this issue
