Are you asking how to adjust the brightness of the display? If so, you might want to read the user manual, and avoid trying any of the stuff in this forum. You'll just jack up your phone.
Who voted this thread up?
I'm hoping the person is asking how you can programmatically control the level of luminescence in our Epic 4G and not how to turn down brightness manually.
The screen at lowest setting is very brite still. I wear dark shades at night to help reduce the brightness. Cheap 1 dollar Target shades in the 1 dollar section. Its pink and made for little girl princesses. But it does the job. I noticed the xtreme v1.2 kernel has a lower setting. Try it.

Hello All
Just came across this forum and a thread on the pink screen issue.
Do you reckon this one has the same issue?
All of the phones are the exact same and have the exact same "issue". I use my phone on maximum brightness all the time so I never notice it. It's only noticeable if you use the phone on the lowest brightness setting (Why anyone would buy an AMOLED phone just to use it on the lowest brightness is beyond me)

Yes i'm fairly sure they do. But at anything over the lowest brightness it doesn't occur. Again, why you would buy an AMOLED to use it on lowest brightness is beyond me

Check the appropriate thread: there is a huge difference between handsets. Most are like this, some are totally unaffected and some are basically defective.
Yes poor answers, I do not have any pink even on the lowest brightness settings. This means your device is defective and you should get it replaced as many others have done. And yes there is a thread dedicated to this issues:

Im a total OCD for these kind of things. pink issue, dust under screen, dead pixels etc... I don't have the pink issue. It was one of the biggest concerns for me when I ordered the phone. I had seen sample photos from the nexus one that had pink etc. I think there are two issues. A screen issue, and a camera issue? anyway, I don't have pink in my screen at low setting (which I use ALL the time indoors to consevre battery) or any other setting. I also don't have pink in any pictures or videos I made with the phone.

What do you think of the examples i posted?
I only notice the off-pink tint in GMail. Nothing major tbh.
I cannot see any pink on your photos at all, but I went to my brightness settings and copied what you did in the screen shots and YES my gray looks like it has a red/pink/rose tint at the VERY lowest setting. At 5% brightness it's fine, gray. at 0% setting it has the rose tint. This is NORMAL and a limitation of the display technology (pentile matrix). If this is what you mean, your screen is normal. It's only certain shades of gray that will be affected by this and normally only at minimal brightness settings. I thought you meant you had a pink blob on the screen centre etc? If you just mean the gray menu and ntificaiton bar etc appearing slightly rose coloured at lowest setting, this is normal. I presume the grays are fine when the you move the brightness bar up from 0% to 5% or 10% setting?

Yeah its fine when its not on the lowest setting.
Thanks for taking the time to reply
Does anyone know if there are any working ways to adjust color temperature? I think most methods require a modified surfaceflinger library. My screen is sickeningly bluish green.
Thanks.

Sounds like a bad screen. I'd take it back. Mine is very balanced. Super saturated but very balanced.

I agree, my first one had a bad screen and a dead pixel right in the center, the screen quality on my new one is better all around and I wasn't even expecting there to be an improvement
Thanks for the suggestions, but the other ones I've seen don't look any better in terms of their greenish-blue color cast. I've read it's typical of AMOLED displays. I just want a way to adjust white balance like CM has.
...and I've discovered the answer. Chainfire3D's Pro version has support for Custom color "nightvision mode". Basically, exactly what I wanted. It works perfectly! Do yourself a favor and get this and drop your green and blue levels down a tiny bit.
You just saved me a two hour drive to get a new phone. Great find.
I was wondering from my understanding the amoled turns off the leds that are within the black area of the screen display. So if I turn my wallpaper and most layouts into black colour will that help reduce the battery consumption through the screen or will it be almost insignificant?

I would say insignificant at the risk of not enjoying your phone. Does it really matter if you squeeze out an extra 30, maybe 60, minutes at the expense of not just using it and enjoying it?
Everyone spends too much time obsessing over cranking out every last little bit that they forget to stop and smell the roses.

According to the quoted site, a white pixel on a SAMOLED screen takes up nearly 6 times as much power as a black pixel, as all sub-pixels need to be lit fully. Being that the screen is by FAR the biggest consumer of battery on our devices, I'd suspect that turning down brightness and throwing on some black backgrounds will make a difference. The site also analyses average battery gain (on non-pure backgrounds):

This guy tested SGS3 and concluded 3 hours extra battery life, regardless of brightness: http://forum.xda-developers.com/showthread.php?t=1882467
If you're indifferent, then pick black. If you can't stand black, then pick white.

In my line of work, involving alot of field work where I do not have the luxury to charge my phone whenever I want, it matters. Besides I do smell the roses...even in black.

Incase youre wondering what this job might be that doesnt even have electric sockets in close proximity ..im trapped in a chamber for a month doing saturation dives where I only get to charge my phone once every 2 days.

Then I'd say get a second, even 3rd, battery and crank up the colors.
And, to be fair, your situation is obviously on the extreme compared to everyone else trying to max juice.

Black is beautiful on amoled. ..I use the dark background on tapatalk. ..I wish Google currents had a black background. ..hope they introduce it.
scribbled from my note 2 (N7100)
Yes, it will help a little bit.
More info @ How to improve Samsung Galaxy Note 2 battery life?
Well,this frustrates me a lot,I'm just uploading video so you can see and compare to some cheap other chinese phone.
I'm noticing yellow tone all over screen,kinda like there is a night filter on with very low bright nightlight settings.
I increased brightness all the way to 100 % didn't help.
I also removed plastic cover from phone,nothing, still present.
I even switched to Vivid display settings before that and reduced RGB (R channel all the way,G to middle and Blue increased all the way) and set tone color to cooler slider all the way,no difference.
So,since I purchased using phone,is this some software bug/issue or I got faulty screen (maybe some kind of damage from sunburn),or this is just how this display work?
I'm uploading video and will post link soon...
So anyone else having same issue,and what to do,be sure I can not RMA the phone since I purchased it used.
I'm also anxious that the screen might die on me soon.
But this yellow tone frustrates me a lot,colors are not accurate at all because of it.
does it show in safe mode? what happens after reboot, goes away and come back later or...?

Hmm,why would I want to access safe mode,I don't have issues with phone except bad wifi and this issue.Mostly it's noticeable while watching vids (youube),look here if you can see the difference...but maybe it is suppose to be like that.
I set color mode all the way to cool tone and no difference to my eye.
I called a friend on a drink which has N10+ too,then we put 4k Nature video on each of the phones at same time and same screen lightning intensity.
No diference,between them...so now I'm confused totally.
Are my eyes cheating on me,is it possible that there is slight yellow tint (like light night light filter) or something is wrong with my eyes?
Is it possible that maybe screen adapts it self based on ambient light so I'm seeing yellowish tone...who knows,but I do trust my eyes,though picture was the same color accuracy on both phones...
I'm totally confused now...
I have currently 2 note 10+ phones. One which still has the original display while on the 2nd I installed a new display with frame. Comparing both these phones now, the older display - about 1.5 years old with light screen burn on the bottom is more yellow than the new one. The new one is very white compared to the old one. Maybe your display is showing its age?
damn...it was a damn mask/cover with yellow tint over it,not display...how was I stupid.
Some weird posts here, didn't you say you removed the film earlier ?
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.
