Question Avoid keyboard burn-in - Samsung Galaxy S21 Ultra

Hello all, my past 3 AMOLED phones have been facing burn-in where the keyboard is displayed as I tend to chat a lot! Can anyone give me an option to avoid it? Please don't troll and say use less keyboard!

Might help if you keep the brightness on the lower side, other than that seems like catch22

Also choose a darker theme for the keyboard.

That's why it kept happening for me... The I turn it to light mode and then the burn in goes away!

Dark mode will help reduce it, but I leave my phone set to auto switch light and dark mode based on sunrise and sunset, this way whatever app I'm using also switches, so the light and dark apps, flip button colours as well so anything white on a black screen also becomes black on a white screen so it helps reverse any burnin in that sense too.
For example, texting apps usually also have white icons at the top which can burn in with dark mode, so if you switch to light mode, the same icons are now black on a white screen, so the screen burns but the icons don't, so it all slowly burns in together and nothing becomes noticeable.
Been doing this after getting burnin on my S10+ using only darkmode and light icons left burnin. And then on my S20 Ultra I did the flipping light and dark mode and never had issues but I also had the full screen settings to hide the pinhole camera so it made the entire top black, and then One UI 3.0 came out and they removed that option so now you can't hide the pinhole camera and I had a burnin bar across the top from where it was black lol.
Now on my S21 Ultra I have the light and dark mode set to flip at sun rise and sun set, and I can't hide the pin hole so maybe third phone is the charm here and I won't have any burnin at all this time haha.
Hope this helps.

There is no burn in with AMOLEDs; they have a finite lifespan and get dimmer as they age before finally failing after many 10's of thousands hours.
Don't over drive them by using them at maximum or near maximum levels.
High energy blue pixels are the most susceptible to damage, red the least because of its longer wavelength.
Use manual brightness control. Avoid going much over 50%.
Using full brightness reduces pixel lifespan as probably does high temperatures ie direct sunlight.
Limit usage at full brightness by the second*.
Using manual control ensures you're aware of it and keeps the phone from auto jacking it up on you when not really needed.
Turn it down in low light; don't burn out your retina's as they aren't replaceable.
Use dark mode whenever possible. Use dark or black wallpaper. You Good Lock to get rid of the stutus bar icons; simply use the pull down notification screen.
My 10+ gets heavy usage every day with a lot of keyboard time. At 15+ months there is no discernible weakness or dead pixels of any color at any brightness level.
*this is especially important with static images

you say you had burn in from keeping a black bar in the area where the pinhole was?
that doesnt make any sense. If it was black those pixels were off and there wouldnt be any burn in
ಠ_ಠ

Get Gboard, And change it to a dark skin, I've never had any problems

Reverse burn in, the screen area being used has a yellowish tone to it from being worn in over time, no matter how long the display is on, it's always burning in and the colour always adjusts over time from the burn in, it's the image retention burn in that people talk about, but the entire screen is always burning the entire time it's used. So by never using the top area the pixels are fresh and have a cooler tone to them than the rest of the screen as a result of this.

Indeed. And to add, perhaps occasionally change from white to black keyboard to even things out.

This is a good one. Says something about fast charging and not showing this message again. Guess they forgot to check don’t show again.

No offence but:
Pay 1.2K for phone after you see super HDR, huge brightness etc. and then limit everything to minimum? Seriously?
If I see them, I will ask EE(my phone provider) to replace it. I had same issue with OP 7 Pro, screen burn ins, they have replaced phone.

From normal use there will be no burnin. However, if you keep your display on showing the keboard all the time it will burn in. Also pixels start to burn in once they are on

Samsung shifts the AOD clock to help prevent this. However I use only tap on AOD now.
Perps know the deal, organic LEDs have a finite lifespan. Yeah you can drive your car as fast as it will go but you probably don't because you know it wouldn't last very long.
You wonder why the price tag keeps going up?
Freebies are never free.
Using in direct sunlight or at 80+% is just asking for it. In most cases completely avoidable. One can at least limit the time of use at full brightness and not have a homescreen that looks like a Vegas billboard.

I live in Texas desert, the sun here is intense.
It burns out LED traffic lights all the time; OLEDs are far less tolerant.
Simply use in the shade.
The individual pixels are microscopic. That they work at all is amazing let alone being capable of high lumen output with extremely excellent color/gamma rendering.
The AMOLED matrix has 10's of thousands of active solid state components not just the OLED pixels themselves. All are hest sensitive plus the fact the display is helping to dissipate mobo heat while producing heat of it's own. The most heat sensitive component, the OLED is smack on top of this glass heatsink*.
Direct sunlight in especially high ambient temperatures is a real bad plan. You can fry any display like this.
Know, understand and respect their limitations. You will be rewarded with a long lived gorgeous display.
*glass is a good thermal insulator. Do tempered glass protective screens increase the thermal burden? Most likely. If cool at first the added mass will be protective but once the device (or the sun) heats that mass up things will go down hill from there and the display temperature will rapidly climb.

Common sense should prevail I guess. I live in a place hotter than Spain. If I were to use my device in the middle of the day in bright sun light it’ll cook after 15mins. Hence why I don’t. But then would any other device.

Gear Live and burn-in

Since Android Wear has the screen on all the time, and the Gear Live is AMOLED wouldn't burn in be an issue? the galaxy gears on display at retail stores have a bit of a burn in problem.

From what I've read, the watches are "always on" in the sense at the screen stays on, but the lighting is turned off. So instead of having to refresh the UI every time the watch is seen, it just turns the light on. Similar to a backlight for a laptop. Display models are usually always lit so they burn in due to the display being lit 24/7.

As far as I am aware, AMOLED has no backlight...that's sort of the point...every pixel "burns" individually.

I said similar because not everyone is familiar with the way AMOLED's work. But the same thing occurred at his Best Buy as would any modern portable display, device is constantly lit, and resulted in burn in.
I'm sure the user has an option to turn off the display if they choose to.

they also have dark mode and dim (holding palm over the screen) don't they?
hopefully there'll be something within all this to prevent issues.
Only LG G Watch has "Always-on" display, Gear Live and Moto 360 have a button to turn it on and yes in the Setting you have an option to adjust the brightness.

After watching like, 40 videos, I'm pretty sure that they all have always on. The button on the Gear Live and the 360 are to act as a physical way of turning off the display entirely as LG allows by covering it with your palm. But yeah, from what I've seen, the Gear Live goes into the same low power greyscale mode that the G Watch goes into, and both support wrist flicking to activate the display.

I did watch about 40 videos too lol and LG G Watch was the only advertised as "screen always on" as Gear Live has Super AMOLED display and even greater resolution than LG G Watch so the Gear Live would burn out in matter of hours.
LG G has 400 Mah battery, IPS display and lower resolution so it can withstand being "always-on" for at least 36 hours as advertised.

Except, you know, on the official Google page, and in the videos that I've seen, the screen also just times out to a low power, black and white screen (referring to the Gear Live). Super AMOLED is more power efficient in idle / dark screens due to the nature of individual pixel lightning, so I don't really understand what you mean by the Gear Live would burn out in a matter of hours (they should be relatively the same from what I can tell).
Always on = standby (i.e low brightness, dark screen). It does not mean full brightness, always coloured watch face. No way in hell. If that was the case, why would the displays time out in what appears to be 5-10 seconds?
Yeah.. I'm going to wait on conclusive battery testing before making my purchase. I've got like a week anyways, might as well.
Also, I'm legitimately concerned about screen burn in now, given the nature of AMOLED.

i've been concerned about screen burn in from time to time as well (most recently with the gnex). but then i realized it is highly unlikely i'll have the device for long enough to achieve burn in and/or notice
I've been playing with my Gear Live for a couple of days, so here's what I can tell :
- The screen is "Always On" by default, which means it will get dimmer and switch to a black background on most watch faces (and for AMOLED, black means "off").
- You can set it to turn off completely.
- In order to dim it (or turn it off depending on the settings) you can either wait, cover the screen with your hand, or use the physical button... The button is not really practical and seems to serve absolutely no purpose since you can use the screen.
- I haven't noticed any burn-in at all yet
- I think I noticed that from time to time the facewatch (I'm using the one with the digital hour in the center and analog minutes, I think it's called "digitalog" ) switches a few pixels to the right or to the left. My guess is it is to prevent burn in, I know most plasma TVs do that too.
- I had a Galaxy S2 for several years before switching to a Nexus 5, and yes, the toip of the screen where the notification bar usually is was burnt-in (or rather I think the whole screen was burnt except for this black bar). It was noticeable on full screen apps but never bothered me. Even if it happens on the Gear Live I can't see it bothering me... It's not like I'll be watching movies on it...
So my guess is you should be fine... But if you're really worried you can always disable "Always On".

I have a Gear Live, and can confirm this is true. I've seen it on multiple watch faces.

I own a Gear Live and can confirm that it does indeed have an always on display (which can be toggled from settings) that dims to gray scale when not in use just like the G Watch.
At the same time I can also confirm that having my watch now just around 3 weeks has already showed some very minor signs of burn-in. Typically when in apps or settings. As I said though its very minor and not really noticeable unless you're looking for it. That said though it is there.
Also to clear up battery life the Gear Live can withstand 36hours of always on screen. While I typically charge my watch each night I have tested it and can get it to run from one morning through to the following night before the battery reaches 5%. This is with the Always-on display option enabled.
Are you guys leaving the screen on all night when you're sleeping? I know its not lit up all the way but like the dimmed version of the screen. Like I'm using the simple clock. You think its okay to leave that on all night? I'm thinking it'll be okay cause it'll gradually change over night so it's not technically sitting on one time for 7 hours.

I am a little worried about burn in myself so I turn the device off at night when I charge it. Even though the pixels should shift with the default watch faces I just think it's a safer bet to power it off.

Burn in? Life span of p-oled always on?

I just got the amazing lg g watch r. Very satisfied with it. I am just trying some watch faces and i found this great one for example:
https://play.google.com/store/apps/details?id=net.ddroid.aw.watchface.rf03
Very happy with it but I wonder....
How real is the danger for screen burn ins? This watch face has for example a green background in ambient mode. I keep the brightness as low as possible, but still readable (great thing of this watchface is that you can set the brightness of ambient and active mode as low or as high as you want) but still the oled screen will always be green..
Is this healthy for this kind of screen? Of course I can turn off the green background and have it black and white in ambient mode, but I like the effect of the screen being dimmed and going to brighter green when twisting my wrist.
But I don't want the screen to go to waste already after a while... anybody have a theory?
What is ambient mode? people keep mentioning it. This watch has no light sensor.

If you want to use the "always on" feature w/o worries, green is the colour you want.
Greem OLED compund has 3 chracteristics that makes it the best choice:
- most visible light from the whole spectrum (for the human eye, that is): this mean you need a very low brighness level in order to see it (power and burn-in safe)
- the most power efficient sub-pixel (1.5 times as economic as red and 2.5 to 3 times ore econmic than blue).
- the most resilient (lowest degradation over time, twice compared to red and 4 times compared to blue).
So, if you like always-on display and you wnat the most out of your watch, green is the choice for AMOLED screens.
**** note: the numbers above are a synthesis from specialised web-sites as well as from my own measurements with OLED screens (Samsung models at least). ****
well, green is the "best" color to display on OLED screens - but black (=pixels are off) would be way better regarding burn-in and battery
It seems that the watchface you linked has a black mode with green font as well - use that one in ambient mode and you should be good

Yeah, this seems the safest option to me too. But the effect is not as nice of course when the screen becomes active. Colors get inverted when the screens goes bright. The effect is cooler when the dimmed green background goes bright, like you turn on the backlight
But I'll stick with the safe option for now, I just don't trust it

I thought blue was the easiest to see, hence its used on police cars and ambulances.

Yellow
I was actually curious to see if anyone will search ... GJ.
What is yellow made of in RGB world (AMOLED is RGB)? : RED + GREEN.
What is closer to yellow (in terms of wavelenght), red or green? : GREEN ...
That why, the most visible pure colour of the RGB matrix is green ... which happens to be the most economical one to use. Double win
Sure would be nice if it had a proximity sensor, so it could turn off the screen when inside my sleeve. I figure that would pretty much solve the problem for me.
That would definitely be a plus ... but the question is: where to place such a sensor w/o breaking the design? Moto 360 solution is not on everyone's liking.

Non-uniform intensity across screen at low-brightness settings?

Hi,
Has anyone notciced un-even brightness across the screen at low light levels (for darker colors)? I thought it was just the nature of these OLED screens, but I don't see this with Galaxy Phone with similar display type, so I'm wondering if I just have a defective unit with bad display.
To test it:
- Do this at night (when ambient light is fairly low).
- Lower brightness down to the lowest setting (turn off auto-brightness)
- Open Chrome browser, and close all tabs, so that you get a blank dark screen with just the "+" icon. This leaves a dark gray background, just enough to notice if there is any uneveness in brightness.
On my unit, I see about 3-4 inches of bands/streaks of darker areas at bottom half of the screen. If I rotate the tablet, the darker areas stay in their physical location (so these bands become vertical instead of horizontal), so I know it's not a software issue.
I have a couple of weeks left before I need to decide on whether to exchange the tab, so would appreciate if anyone can help me verify if this is normal thing with these screens.
Many thanks, Tony.

I have notice a similar thing, mostly on gray - dark gray backgrounds, and not necessarily at lowest brightness (low enough though). I wanted to check about it on a couple of devices on display at retail stores but it's hard to test there.

Hi tonyc1,
Having had 4 of these I can confirm that this unevenness is normal on the 9.7" screen but was not present on the 8" model.
I went through 4 to get one that was reasonably even, 2 of them were pretty awful to the point that the greyscale was all over the place.
The unit I settled on has a slightly darker band in the middle of the screen and a slight darkening at the very top.
I owned the original tab s 10.5 and have to say the screen on that was more even and detailed, I prefer the former factor and speed of this S2 but the screen is a step backwards.
Hope this info helps.
Cheers
Thanks for the notes and confirming this is a somewhat common issue. I guess I will live with it for now..

How to avoid the AMOLED flickering?

I've recently bought the 9.7" version of the Tab S2. I was aware of how unrealistic and oversaturated the AMOLED display is on default setting, but luckily this can be turned off, so it was the very first thing i did (though now the white balance is off, but at least it is not oversaturated).
Unfortunately i wasn't aware the fact that the display at below ~75% brigthtness flickers. The lower the brightness the more disturbing it is. And it drives me crazy. I hate the flickering cheap cr*p LED light bulbs, i hate that most notebook screens with LED backlight are non PWM free, and are flickering And after having this tablet for three days, i am hating it too. I frankly believe these products should be banned, because it hurts your eye, and your brain. I thought when we said good bye to CRT monitors, flickering screens will never be an issue again. Unfortunately they are :/
After googling the internet i found this article gs5.wonderhowto.com/how-to/eliminate-screen-flicker-lower-minimum-brightness-android-0157760 but the solution unfortunately requires a rooted device, wich would trip the knox and void the warranty, so it's a no no for me. Then I found several other apps on the play store which are doing the same without requiring root access: drawing a black overlay over the screen and you can set the transparency of it, so you can get a lower brightness without the flickering, because your screen brightness is around maximum, the lowered transparcy of the black overlay makes it less bright. Unfortunately none of these apps work like the one for the rooted devices, wich has a second slider at status bar, so instead of the brightness you can change the transparency at the notification screen. The non rooted apps i found do not work this way, they don't have the extra slider, you need to tap them, so you can get to where you can change the trasnparency and that's very uncomfortable. I tried so far Darker and three other Screen Filter apps, but none of them works with a second slider :/ Also using the Screen Filter apps when there is a smooth color transition on the dipslay (default background picture for example) gives ugly end result. Using a Screen filter app might reduce battery life so i might need to charge it more often (i don't care), but since the display is not flickering, it is always on, it might will burn in faster (i do care, i intend to use this tablet for 3+ years) So i am currently in debate wether i should return this product and get my money back or not. It is a really great device, but this terrible flickering of the AMOLED screen makes me super unhappy, wish it had an IPS display :/
If this is an issue for you too, and you found a Screen Filter app with a second slider at the notification area (without requiring root permissions) please let me know.
Is this just an s2 thing, nothing of the sort on my tab s?

It's not an S2 issue, I've seen several other phones and tablets in low light conditions set to a low brightness flickering like mine.. But you can test it, set a low brightness and start waving your finger in front of the screen like crazy. If you see ~10 seperate fingers -like in the picture attached- instead of one blurry (what you should see if there was a constant backlight), than yours is flickering too.

I see what you mean, but it doesn't bother me as there is no perceivable flickering at all and it only happens when the brightness is below a certain level.
If that certain level would be around 20% brightness i wouldn't care. I haven't tested out yet, but that certain level is somewhere below 70% So -for me- it would flicker all the time.
Eh, there is no screen flickering but your finger is flickering over a light source aka *screen*. It's an optical illusion you are referring to.
I am also very sensitive to pwm on displays, it takes me less than a minute to feel sick from the display having pwm.
Any further solutions to this? Thank you.
I'm using the the app 'Night Screen' it does the job on Android 7.0 on my LG G6 which uses pwm under 35% of brightness even though this is an ips screen. Hope it helps.

I've recently bought the 9.7" version of the Tab S2. I was aware of how unrealistic and oversaturated the AMOLED display is on default setting, but luckily this can be turned off, so it was the very first thing i did (though now the white balance is off, but at least it is not oversaturated).
Unfortunately i wasn't aware the fact that the display at below ~75% brigthtness flickers. The lower the brightness the more disturbing it is. And it drives me crazy. I hate the flickering cheap cr*p LED light bulbs, i hate that most notebook screens with LED backlight are non PWM free, and are flickering And after having this tablet for three days, i am hating it too.

So here is the app( https://play.google.com/store/apps/details?id=org.js.oledsaver ) to avoid pwm & use the phone with low brightness.
App name is OLED SAVER
It's simple. You install it & follow the instructions & use it. Enjoy! ?

Thanks for answering this 3 years old post I used Darker in the last three years to eliminate the flckering and was happy with it. I checked OLED Saver now, but it's permissions says to me it's a big no no.
Unfortunately, since Android 8 apps cannot draw a an overlay over system areas (notification bar etc., thanks google! ), so i guess i'll never have an OLED screen phone/tablet again.

Max brightness bugged, help me pls

I am experiencing automatic dimming of my screen when set to maximum. The big thing is Adaptative Brightness is Off. I also set Power Mode to High Performance to make sure power management would not dim. I even bought an app that supposedly cranck up brightness beyond system limits (did not work)
I first noticed this when taking pictures of my garden in bright daylight, the screen was dim and even going over the orange marker on the dial I still struggled to view the screen (sun was almost 90 degree angle).
However when I placed my hand over the screen I could see well but then I noticed a sensible dim. At first I thought it was some king of optical trick, so I tried to repeat the experiment in different conditions to the point that I would simply crank up brightness and have a strong light over my phone then I used a black sheet of paper just above sensors. If I take the sheet off the brightness ramp up a bit, if I put the sheet over the screen dims. And again no auto Adaptative Brightness is turned on neither Power Mode in save.
I guess this wasn't supposed to happen, if I want to ramp up brightness as much as I want I should be allowed and the system should not interfere with my preference? I don't need to justify my use to anyone but as a courtesy to those that are inclined to help me, here it is: I work a lot with gardening and construction all day, including strong daylight, and I need to take a lot of pictures for my work.
What can I do to squeeze this bit more brightness from my Note 9?
Thanks a lot.

Try the the twilight blue app filter. It works wonders with the bulb features on your phone

Do you have a screen protector? Could something be obstructing the sensor on top?
