Hi,
this is a topic I want to start in order to help the development of more intelligent brightness control for Galaxy S (probably regional variants of it will benefit as well).
It began with my PM to some of kernel DEVs that I've noticed brownish color instead of black on ONE brightness setting. My idea was to omit that one brightness level.
Overnight, I already got two responses. One that it should be no problem and one that the link I sent might lead to fixing the problem I mentioned as well (color correction).
The other, connected to brightness topic, thing I've noticed is that auto control of it is retarded. First, it's too jumpy without any reason (like let's say change of outside brightness) and second it likes to set level that burn the eyeballs. I've never had such problem on my CM Hero.
Here's my original PM:

Hi,
I'm PMing you as the most popular kernels coders.
Long story short: SAMOLED screens like to make black or similar colors brownish at low brightness. I've (and not only me) noticed that there's a step just about min. when it starts to be brown and a next step after that it magically stops. The idea is to omit this step at all or just in auto brightness table. I believe It's doable by using those methods.
The original story begins here from the first half of #522 post
Like I've wrote there, this problem exists in all kernels and all color temperature variants of them + stock one.
If you're interested, please respond me. If not, also respond as I'd like to know if I can count on anything.
Thanks

Gizmodo - Why iPhone 4 and Android Brightness Controls Are Effectively Useless
My random thoughts:
One option would be fooling the sensor that it is less bright than it is
Another, more proper I believe, it to modify some brightness tables to leave extreme brightness levels to extreme outside light situations. This one would also help skipping this "brown" brightness level as like I said, it looks to be only one level
Color correction MIGHT fix "brown" problem too, but I'm not sure as COLD and WARM kernel variants didn't changed this brown problem (unless colors are optimized only for some of the levels like I've read at VOODOO site)
CM 6 already has such brightness level options in Settings-> CM Settings - > User interface -> Automatic backlight -> Use custom(just checked on my Hero) so probably lot of code can be reused (as I believe there is CM for Galaxy S)
Kernel DEVs, fell free to hijack this thread. It is to help your cooperation (unless each one of you prefer to solve problems on they own ) Btw. don't be offended if I didn't included you in the DEVs list I've sent my PM. It was late and I PMed only those I've noticed that they kernels I've used. All of you are more than welcomed.
Other, please don't post "I cannot see any brown", and those one that can see it, please stop posting about info after first 5 people do
I'm so happy to read this threat. I had posted questions about display and auto brightness a couple of months ago in the questions section but never received any credible responses.
My problem is that when I turn auto brightness on, not only does my display get exceptionally dark, but it becomes very noticeable that e.g. grey turns more brownish. Comparing my display to yet another Galaxy S confirmed my suspicions that this is not they way the display is supposed operate, i.e. compared to mine the other Galaxy stayed a lot brighter in equal lighting conditions and the grey remained grey (instead of brownish-grey like mine). I compared the grey tones of the numeric buttons in the stock Dialer APP to conclude this.
I suspectED the light sensor might be defective, but I have run the test menu on a couple of Galaxies (*#0589#) and the units always display the same values when put next to mine.
You might see why this is bugging me so much, it seems my galaxy's display is not using less battery even though I get less brightness than the others on auto brightness. Unless I manually bump up the brightness to full the colors on my screen look dull (grey turns Brownish, and over all it looks not as alive) as compared to other units. Simply bumping the brightness up is of course not an option, this drain the battery like crazy.
EDIT: I too have tried the various Kernels, hardcore warm and cold, voodoo w/ color fix sadly all to no avail
EDIT2: @embrion The above all doesn't explain why our phones have this problem, but the far majority of Galaxy S phones doesn't. Of course I cannot statistically back this up, but I have not physically seen any other device that gets brown on autobrightness like ours. Any Ideas?
Do you say your friend's Galaxy S doesn't turn brownish or it does but gives higher brightness than your device in same lighting conditions?

It does not turn brown and appears much brighter in equal lighting w/ auto brightness ON. I edited my post above, please read again if it was unclear before. Thank you!!
You should check it at manual brightness at level set few steps higher than min. I'd like to separate brownish display problem at one brightness level from inproper light sensor measure

Like I said, the light sensor does not give an improper measure, the readings in *#0589# menu are equal across the devices (including mine). The brownish color tones do, to some degree, disappear if the brightness bar is set two ticks to the right of minimum.
(Auto)brightness corrections
Original Auto Brightness level is too high & sluggish.
It 's need to fix like a voodoo Brightness level fix (2.1 only).

Which CSC code do you have? I mine was originally XEN (Netherlands). The units I tested that did not have the problem were all DBT (german Sim free). Just asked my brother and he says his phone also gets brownish (also XEN). Have to check product codes later, will update then.
Mine is XEE (Orange, Poland)
Supercurio did some tinkering with those settings:

My screen has brownish/reddish deep grays on brightness settings under 16-17%. However when I set it over 17% and use screen filter app deep grays are NOT brownish/reddish, this means there is definitely something with lower brightness settings.
Xan, check out the link I've posted in the first post. He gives sources that might be helpful
And the problem appears only at 2nd step of brightness (counted from zero brightness)

@embrion so did you pm Supercurio? What did he say? It's too bad this color/sharpness fixing will probably be put on a back burner what with Gingerbread and CM7 development. D*RN IT! I tried an app in the market that is more precise than the built-in slider. Try it out Adjbrightness (free). I punched in all values possible between 2-255. The tipping point (where the browness is gone) lies at when you go from 34 to 35. Is this the same for everyone suffering from this problem. Please remove all apps like e.g. 'screen filter' before you try!
For me crucial step is going from
/ # echo 53 > /sys/devices/platform/s3cfb/spi_gpio.3/spi3.0/backlight/s5p_bl/brightness
to 54, however I'm running trasig's voodoo.
While 54 and over looks ok, lower values are... reddish/pinkish.
@schiphol: yes I did but no response. In dark colored Gingerbread era, this problem will be become more and more evident.
@xan: dzieki I'll flash latest Darky as it is based on trasig's voodoo and try your fix.

Supercurio just responded me, I'll let you know about results

No fix there, just a different behaviour...
Would like to see this in next voodoo, might even write some simple user interface for this.
I have an idea but its not quite clear yet, however if this patch will let most users 'calibrate' their screens.. I think I'll give simple GUI a shot.
@embrion
Could you perhaps upload the screenshots you talked about in R64's thread so I can replicate. Because of different kernels and settings I want to try and establish beyond a doubt that the problem we're having is of the same nature and root cause. Thanks
This wont be visible on screenshots. You need to make a photo, problably with DSLR and know how to do it
I'll try it today and let you know
According to Supercurio, this is Samsung's color profile deviation, not SAMOLED fault itself.
Anything software broken can be software fixed
@schiphol, xan: yes, it won't be noticed at screenshots, I've already compared R64's black notification bar screenshots and my brown ones. Color picker showed a little difference in color (R:24, G:24, B:24 or something VS RGB: 0, 0, 0 - true black). Such difference should'n be visible and is not visible from software screenshot point of view but Samsung color profile makes 24,24,24 brown IN REAL LIFE while 0,0,0 is still black. I repeat, they're both black at screenshots no matter which brightness level is set, but only 0,0,0 black doesn't look like brown when viewed by bare human eye. Samsung profile at this brightness treats 24,24,24 as brown while it should as black.
--edited--
You're right, Xan. It's just another, ( but 1337 ) method of changing the brightness. I thought there's a plaintext table with levels accessible to change by hand
Hi Ok I have kept the brightness at 2 clicks to the right from minimum to stop grey from looking grey-brown all through today. Now my display accounts for 95% of the battery usage, it has never been this high before. The battery is at 25% whilst I only used the display for 44 minutes.
Thats ridiculous battery drainage and should be taken into careful consideration when a fix is developed for this issue. Are you guys having a similar experience??
do you guys know how to or what apps can change the auto adjust level? and please dont say just manually change it, i like to use the auto feature, its there so i can be lazy.

Juice defender has an option to set the brightness all the way from -80% to +150%. So autobrightness would have a larger (or smaller, if you prefer) range.

Have it. Recommend it. Slick app from a great responsive developer.
just use the notification bar
Hey guys
I found out that if you tap the notification bar on the top and slide your finger left or right, you can adjust brightness as you like. I think that is the easiest and quickest tip I found on this forum. not sure where I found it.. hope that helps..
^^ only works if the brightness toggle is off.. Awesome feature on sammys..

There is an app i am using that allows you to adjust the levels that the auto brightness use.
Called: LogGraph
it gives you a graph divided by roughly 12 steps of the brightness sensor so 0-12.
you can set the brightness level at each step the default (which i am using) is roughly:
Sensor% - Brightness level%
0-0
10-5
20-10
30-15
40-20
50-25
60-30
70-40
80-60
90-80
100-100

Thanks I was wondering why it didn't work.
Sent from my Hercules using XDA App
Reviving a slightly older thread here for some feedback.
Lux is a great and well designed app; I've been having issues with it - it doesn't seem to sample from the sensor (light or camera) when it wakes up, even though that is how I set it. I sent an e-mail to the developer, so hoping he can help me out. I also found it hard to understand the "levels" both in basic mode, and the lux/luma in advanced mode. I came from Cyanogenmod (on an Evo 4g) so I understand how the sensor works, but for some reason, whether it be the GS2 or Lux, the sensor does not seem to pick up a lot of variation in ambient light. I can cover up the sensor with my finger and the value that is getting doesn't seem to go below 2.
So I'm still struggling to get the auto-brightness (with an app or with the factory algorithm) to work properly compared to what I was able to get on my Evo 4g w/ Cyanogenmod (which was perfect by the way - once I have it all set up, absolutely perfect auto-brightness).
Actually I edited the framework-res.apk file and that did the trick. I tried lux before but it still didn't work like the default auto brightness.
I'm just sayin!

I believe you that Lux doesn't work like the factory auto-adjust...no matter what an app. developer does, you can't replicate the responsiveness of what would be in the framework.
Could you explain further the edits you did and what it corrected? I am a software developer and I can figure out the basics, just was looking for an idea of what you edited in there and the specifics to get me going.
Thanks in advance!

I basically followed what they did here http://forum.xda-developers.com/showthread.php?t=1235212 to decompile the apk. I made adjustments to the value that represents the brightness under the lowest lighting conditions. I slightly increased the brightness under that value to help mask the blobs under low lit conditions. Hope this helps.

Yeah, saw that last night and just finished. Will probably need to dial in the values a bit to find what is optimal for me.
I'll post a Framework for others to use once I get mine all set. This is definitely the way to go for adjusting autobrightness.
I know this is possible in CM9's display settings, but I'm currently running AOKP. Is there any other way to lower the minimum screen brightness?
I've given Tasker root permissions, approved it as a device administrator, and approved it as an accessibility service. Still, when I use a task to lower the brightness to very low levels, the brightness will only hold for a fraction of a second before it ramps up to the factory minimum.
So is there some system component I can modify to allow lower brightness, or is this only available as a ROM control like in CM9?

FWIW the lowest possible brightness setting can't be altered via the CM9 settings, only the auto brightness levels, both sensor input levels ("bins") and the brightness level associated with that input/bin. The minimum value of 19 for the lowest slot can't be lowered further. There are other display parameters (related to brightness) that can also be altered in the CM9 settings, but it won't accept a value less than 19.
Edit: I see from a link in your sig that you're familiar with the custom levels
Yes we can do it in the frameworks to go lower than 19. I did it on other phones. I'm not sure why it hasnt been done yet for nexus, and ive been too lazy myself.
But we can even take it down to zero or 4-5 etc so its much dimmer at night. Its on my to do list.
Also i posted some kernel code in a similar thread where this question was already asked. But mod the framework is much quicker.

I'm an idiot; I just found it in AOKP. It's in the custom backlight settings.
My experience does not mirror you guys. When I decrease the "screen dim level" in the custom brightness settings, it applies globally. I just did it in AOKP the same way I used to in CM9 and now with Tasker I've taken the screen all the way down to 1

Yes with above linked app. I confirm it works on stock
Sent from my Galaxy Nexus using Tapatalk
I've used a similar app called Screen Filter. My only problem with these types of apps is that I find the black/gray filter they use greatly decreases contrast at low brightness levels (more so than a "true" brightness level at an equivalent setting). Still, if you are running a setup in which they are your only option, they certainly beat having nothing.
The problem with using a screen filter is that it limits the maximum brightness when in sunlight.
I only want to affect the minimum as it is too bright.
Has anyone been able to do this on a stock rom? I too think that the minimum brightness is too high, but I don't want to use the above linked program because it also affects the maximum brightness too. I would like to be able to set custom light levels as per cm9/cm10 and pretty much any custom ROM right now, albeit with my stock ROM. Any flashable zips out there?
Cheers,
Dan
The lowest brightness setting is not dim enough for me in low light conditions so I've been looking to alter it.
After reading around the capabilities of some apps it seems that they only add an overlay which reduces contrast. I would much prefer to do it natively.
I then realised that the AOKP ROM has this functionality!
However, I can't seem to get it to work.
Settings>Display>Custom backlight settings
Changing the screen dim level doesn't seem to change anything for me.
Can anyone offer some tips or advice?
Thanks

Does your display dim more when you select a lower than default value or did you have to change something else?
Did you change the corresponding value in "Edit Other Levels" as well (if you're on auto brightness)? Not on AOKP, but mine is fully functional both on manual, and auto.
Their implementation is the same as CM9 (which is nearly identical, if not the same as the CM7 implementation).
Edit: just a thought, not sure if the AOKP status bar brightness slider is hardcoded to a certain minimum level? Are the results the same if you adjust your brightness via the Settings>Display>Brightness slider?
Settings>Rom Control>Performance>color multipliers.
Drag the three bars all the way down.
As far as your problem...
Are you on auto brightness?
And have you adjusted the "Dim Level" prior to adjusting the screen levels?
(Dim Level is the level your screen dims to after not touching it for 15 seconds or whatever).

Screen dim level is the minimum brightness value attainable (I lower mine to 12 so I can enter a screen value of 12 in my custom levels), but also does correspond to what you mentioned.

I add 2 levels for the high end, and reduce the other brightness levels considerably. Ultimately I usually end up with the perfect'ish level for most scenarios. I hate having to adjust brightness the old fashioned way

Could you send me a screenshot of your custom levels, that sounds like the exact thing I'm after - a dimmer screen in general, and having a lower min brightness.
So am I correct in thinking that you need to lower the dim value in order to set lower values in the custom levels?
can somebody share their CM10 setting for the display light control please.
i find that is it to bright when in a dark room,what setting should i change to lower the screen auto brightness ?
thanx
I am also interested as I would like to decrease the screen's battery usage.
every setting will be personal, as testing conditions and displays always differ. experiment yourself, dont go over the stock limits and if you don't like your experiment's result, reset to default and start over.
search about gamma color control to know what it does.
