Screen brightness - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I have issues with the brightness constantly changing. It is extremely annoying. I believe I have all the settings to where it shouldn't change. Its on full brightness, dynamic and unchecked where it will adapt. It is extremely noticeable on light pages like the web or Tapatalk. This is my 3rd Samsung never had issues before. Thanks for reading

Turn off auto adjust screen tone in settings>display?

Already did thanks. There are 3 settings that affect the screen I think. Its driving me crazy

Yeah, it's a phone wide thing that isn't affected by settings. Happen to me when I switch over to Chrome from a different white display. The whites change, even if every other setting is constant.
Basically, it's a known issue with no way to change it at the moment. Not sure if it continues in AOSP.

Colors changing on s4, not adapt display

So yeah does anyone else have this issue? My s4 colors tend to get warmer and like have a green tint when the keyboard is pulled up any keyboard for that matter in any app with adapt display on or off and auto brightness off or on. Like the status bar turns greenish too. It's so strange.

Yes. But only when the keyboard is up. The color of the whole phone gets warmer

Maybe power saving mode?

Nope. It like changes the
Saturation a little when the keyboard tray is displayed.

interesting.
I want to see if someone else can test this. Open up or even reply and look at the status bar and tell me if the black becomes like a greenish tint as well as the whole screen. Then close the keyboard and watch it change back to normal.

I see it change a slight bit, but my face has to be pressed up against the glass when opening the keyboard to even notice. Is this really an issue?

No but I was just curious as to why it did it

I have exactly the same problem on Verizon S4. It really bothers my eyes as it seems to be changing the white balance / tint simply based on what's on the screen all the time. I have of course turned off all options that have anything to do with automatically adjusting the display.
I have the exact same problem with my GS4 international version. The problem gets even worst when playing a youtube video. The colour of the youtube video and the whole screen changes when the status bar is present and when it is not. The whole screen becomes reddish when the status bar is present and greenish when the status bar is not present. Any help on how to disable or fix this?

No but people seem to not realize it's even there. It's built into touchwiz. Only goes away in like cyanogenmod or something. But I'm sure it can be fixed if a dev wants to help so let's all keep this rolling. Anyone else notice it?

I noticed all the Hues are screwed up, even with out a keyboard being displayed. Internet surfing, playing games, Navigation.
I miss my Galaxy S2 because it didnt have this issue.
Edit:
Compared my s4 with Note2, and note 2 cilors and hues are so much better.
I don't see a change. ..

I have the same issue but mine happens very rarely. It's super annoying. Has anyone tried deleting colorblind.apk?

After I noticed it a few days ago, I think it is ok now, at least not as bad as the first time i saw it. Youtube video seems to be ok now with very very tiny bit of change in colours and contrast compared to yesterday with the same video. I think it might just be some bugs in the software. I did try restarting it many times yesterday and also disabling auto brightness, auto adjust screen tone and adapt display and that didn't help at all but now it's just kind of fixed itself
I just realised that this only happen when the brightness is set at a very low level. The effect is less noticeable when the brightness is high.
Yes so it's throttling the display to save battery and such
Does flashing cm10.1 fix the issue?

Brightness in the dark

I have turned off auto adjust from the main notification menu and I have my phone set to standard on the display settings and my phone still dims when their is a lot of white on the screen, when I load google chrome and in games (emulators). Has anybody had the same issues? I've seen also, but I'm not sure, that the processor still run at 1,458 Ghz, not at 1,89.

There's still a setting you need to turn off in the display options, it's just above the high sensitivity checkbox that let's you use the phone with gloves (I don't remember how it's named in English but it basically means auto tone).
Sent from my GT-I9505 using xda app-developers app
It's the "auto-brigthness" and it's uncheck. Perhaps it's a problem of my rom. I'm on stock rom, just root. Or the solution may be to change Kernel. Those who have custom rom/Kernel, have you this "problem"?
Sent from my GT-I9505 using xda app-developers app
Is under display settings , something with "tone"
Sent from my Superb Galaxy OctaCore
I don't think it's a problem with options. Many users have this problem. I've try many and many options but still have bad results. But you, have you also this problem or not? If yes, changing Kernel must be the solution or not?
Sent from my GT-I9505 using xda app-developers app
I think this happens if you've enabled Adapt Display in display settings. Try switching it off.
Has anyone got a solution to this, I have had this phone 2 days and the screen jumps up and down in brightness and I am sure I have turned off all the auto settings.
One minute the whites are nice and bright next they turn grey or cream then back to bright white.

weird brightness issue

ok, so try going to 0 percent brightness in a dark room and start like moving around the menus, or using Tapatalk.. do you notice it randomly gets more dim, or more bright, on its own correlating to how much stuff is on the screen? like, I was in the touch buttons display menu and as I moved up and down I noticed sometimes it's brighter, and sometimes it's darker. I think the dna kind of did this too but not as harshly as this.
it's not on auto brightness. I'm on 0, but i think I've noticed this at other levels as well. yeah confirmed i notice it ever so slightly on 40 percent. hard to notice since it's brighter, have to look close. easiest to see on 0.
care to give it a try and let me know?
Sent from my VS980 4G using Tapatalk 4
it seems like it gets brighter when there's more white on the screen. when there's more gray or darker colors, it gets dimmer. seems to do it consistently on Tapatalk when going from like a thread full of white background and then going back to my subscribed which is only like 3 things, so 3 little white backgrounds and the rest is gray.. so it's dimmer there.
Sent from my VS980 4G using Tapatalk 4
and when I pull the keyboard up to reply, I'm using a gray keyboard... so it gets dim bc the screen has more dark color on it.. when I drop it down, it's gone and the screen has more white so it's brighter haha
Sent from my VS980 4G using Tapatalk 4
I haven't noticed any dimness or brightness. I have noticed a flickering of sorts on my call icon and home screen wallpaper. Maybe I'm going nuts or maybe its my eyes...doesn't bother me if its happening. Interesting though.
Sent from my VS980 4G using Tapatalk 2
Maybe it has to do with that graphic ram thats on the display. They said its suppose to save battery. Honestly i thought ive seen this happening on a couple of review videos.
oh yeah? I'm wondering the same. at 0 brightness my dna would change brightness levels around and I noticed it often.. wasn't as hard of a change as the g2 though but perhaps you're correct with the gram!

It's called dynamic contrast and is present in all modern TVs and smartphones
Your TV set is probably CRT, hah?
I would think the constant change in brightness would mean sensors are constantly running and chewing up battery. But then again, I have no idea what I'm talking about

Lol u sound like me, then again i have no idea what im talking about. Yeah i was just guessing on the graphic ram. But i coulda swore on one of the vids i saw the phone was really bright and then it changed and was noticeably dimmer, let me see if i can find it, could have been auto brightness but in the same lighted area it was a huge change if it was. Do u have auto brightness on?
Mine almost flickers if I have auto brightness on,its very subtle but it's there

this. Maybe once its rooted we can find where that is defined... hopefully it is not something supper deep within the code and is something simple like a variable.

do you know the explanation as to why it does it? I'm glad it's not just my phone lol. what's the point? save battery?

My G Pro have same problem too.
But i notice when only watching movies, and not always. weird
Here is how it is disabled on Tegra 3 devices. I'm sure there is just an easy of a way for qualcomms chip... we just have to find it after we get rooted
can't wait for root!
btw, there was a secret menu for the att version where you could turn off the dimming when the phone got hot. if we could get that menu maybe we could turn that

I'm not sure if it's the same thing as dynamic contrast, but it also sounds similar to some content-aware brightness settings included in some ROMs.
Does auto brightness even work on this phone? I will pull down the notification shade, uncheck auto brightness, put the brightness all the way down, check the auto brightness box and it does absolutely nothing. Anyone else notice this?
Upon further review, if I go to settings and display settings and check the box from there, it seems to work. Maybe it's just broken in the pulldown notification shade?

Yes I felt the same. There is absolutely no change i noticed when i set the auto brightness. I just set it to 30% manually. Not sure if there is a issue with the sensor or just the software..

In browser screen flicker

Has anyone noticed how much both chrome and stock browser flicker. Since i spend a lot of time inside i don't really crank up the screen brightness. I noticed last night that when scrolling in the browser the screen will often flicker. Its driving me crazy cause I don't have a way to test on another unit. Im on at&t with a d800 can anyone else confirm this thanks. Once again it only seems to do this when the brightness is set relatively low, and auto brightness is set to off.
Sent from my LG-D800 using xda app-developers app
yes. it's that content adaptive brightness crap I'm always bringing up lol.. there's no way to turn it off. it changes brightness depending on what's on the screen. it's horrible at low brightness in the browser and anywhere in general.
my tip, use screen filter instead of dropping down brightness. this helps and you don't notice it. for example I leave my screen at 40 percent and put screen filter at like 35 and it looks almost like 0 percent brightness and I notice no flicker. this is only a temporary solution until kernel Devs get here because I believe the issue is in the kernel, bc disabling it on a software level does nothing.

Not sure if you're talking about the same thing, but check out my thread here for a possible solution.

[Q] Auto-Brightness Confusion

Can someone please explain how the auto-brightness works on this phone it seems to act a lot weirder than my galaxy nexus did. What does it mean when it talks about setting the baseline brightness and in what context? Do you use it? If so what brightness do you have it set to?
This phone has the worst auto-brightness of any device I've used.
I need to read the manual. I'm assuming the baseline is the minimum brightness, but it never seems to change when expected.
I chose to use a 3rd party app to manage it. Lux auto brightness works really well, and you can calibrate it any way you'd like.
Sent from my LG-D800 using Tapatalk 4
I have mine set to 40% on auto. I found the best way to decide the minimum brightness was to set it at a comfortable level in a dark environment.
To test this, set up your minimum brightness, then point the screen (ambient light sensor) at a light source, keep your eye on the screen and it'll gradually brighten. I've found mine to work pretty well and rarely have to manually override it, but the change is a lot slower than my note 2.

Get lux lite from the play store. It works great
Sent from my VS980 4G using Tapatalk 4
Comfortable in a dark room for me is about 5%, unfortunately even in the brightest of sun it seems like the phone never turns its brightness up at all when on auto like this. Anything less than 50% seems to break auto brightness for my device and that is just sad. Even when it works when set above 50%, it takes 5 seconds or so to adjust which is just terrible and the brightness seems to still act funny about how and when it decides to change. It really is the worst auto brightness ever.
Whoops!

Thanks for the recommendation guys that app seems to work sooooo much better than the stock auto brightness so far. The stock auto-brightness is garbage on this phone. Seems like the stock setting either doesn't get bright enough or doesn't get dark enough.
I don't agree, either I have a working phone or others are broke, but this is the best autobright performing phone I've every used, after the hd2, galaxy nexus, note 1 and note 2. Its perfect according to the ambient light situation and is really fast acting
