For those needing dimmer screens

I found the perfect app! Its called, "Screen Filter" in the Market. It puts a virtual filter over the whole display to make it dimmer without impairing functionality.
This is perfect for our Amoled screens because power use is directly proportional to overall screen brightness not backlight brightness like lcds.
Also, don't set it on minimum or else you won't be able to see anything and have to wildly press the screen in a frantic attempt turn it off like me

HAHA this is exactly what I needed for my late night Pocket Legends sprees.

Perfect! This is exactly what I've been looking for, hate disturbing the GF when I can't fall asleep and need to check XDA

I used Screen Filter for about 3 days, and it seemed like the battery drained faster with it on than with it off. I think it's because it runs as a background application instead of simply modifying the brightness.

Poll: Auto-Brightness, Full, or other?

Hey guys - just wanted to create a little poll to see who leaves there screen on auto-brightness, full, or manually controlled but somewhere in the middle.

I use auto, but I use tasker and screen filter to turn the brightness automatically at night.

Auto-Brightness unless I read in a dark room where I manually set it to the minimum (auto usually puts it there anyways). The other exception is when battery is low, I put it at 0% or whatever minimum allows me to see something.

I'll submit a vote when I can indicate minimal brightness. More than bright enough for me unless I'm outdoors.

i usually leave it on min. brightness and turn it up when needed (e.g. outdoors)

i like SGS to be set on auto, it works better than on the SNS
on the SNS i need to set it to manual

I use auto mostly and manual ( 0% brigness ) when watching movies in my room )

I'm at minimum most of the time (voted 'at the middle' as it is the closest).
Please fix the poll!

Auto-brightness most of the time...

i cannot vote as i leave mine on minimum brightness to conserve battery

Almost always at minimum, and often auto when outside.
Minimum being too bright I also sometimes use Screen Filter.
There should be an option to use auto, but choose relative brightness (an offset). Using Screen Filter almost does that, but it is too unstable.
Even beter would be to be able to tweak a response curve : screen brightness in function of ambient light (I want it dimmer inside, but still full brightness outside with sunshine)
I think Samsung does not allow screen to be too dim also because it then shows too much imperfections in amoled...(ex. plain white is not uniform at all)
Using Screen Filter to dim a lot brings bad looking screen. But I guess a great part of it is due to number of colors too low, so you loose too much by filtering. Maybe Gingerbread will improve in this matter (doesn't it manage more color shades?)

I use auto most of the time, except for image viewing and video.
I use JustPictures as my image viewer and set it to automatically turn brightness to full when looking at an image.
For videos I use mVideoPlayer which has a manual brightness override which I usually leave at about 50%.
I also use the Speedmod kernel which allows the brightness to go even lower than normal if you use manual brightness. I use this low setting when using my phone in the dark.

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.

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.

Question Avoid keyboard burn-in

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

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.
