Issue: http://code.google.com/p/cyanogenmod/issues/detail?id=2298
After toying around with the automatic brightness I'm now here to share my settings ...
I use the following settings:
Light sensor filter enabled.
Window length 10 seconds.
Reset threshold 400 lux.
Sample interval to 0.5s.
Light levels use custom checked.
Screen dim level, not sure what it is for but I have it on 1 instead of 20. ((edit: I found what it is for, it's the step size the filter takes? Or not? :s))
Edit other levels...
Number of levels: 18
0 1
10 1
117 17
225 33
272 49
320 65
480 80
640 96
960 112
1280 128
1940 144
2600 160
4200 175
5800 192
6900 207
8000 223
9120 239
10240 255
Allow light decrease checked.
Decrease hysteresis to 10%.
I hope people like my light settings, if you don't please tell me why
Reasons why some settings should be altered:
Reset threshold, should be able to set to 100 and 200 lux. At the moment if you walk into light it takes the filter some time to go up, so 100 or 200 lux would trigger a reset faster. Also the sensor starts at 225 lux so why 400 as a minimum in the first place?
Window length, as for the above, if you walk into light a smaller window length would help put brightness up much quicker in combination with a smaller reset threshold.
If the above two settings could be added in CMParts/ODParts that be great as the filter would be much more responsive to short period light changes. For example if you go from outside to inside or visa versa.
And maybe it would even be a better idea to remove the whole custom light levels and add a linear function to it to go with the filter (configurable) and just have 254 steps (1-255) over 10-10240?
Adding 254 steps yourself is ... A PAIN ><
English please
guys i know there is a problem with the light sensor in desire and i have the same case with mine it this is all about it please let me know how to fix it please.

What ROM are you using? CyanogenMod and forks of it (OpenDesire, DeFrost etc) have a custom preferences menu where you can check out the light sensor values. That is when you leave the filter off and goto edit other levels. Hold your phone in line with a TL light and it should jump to 1280.
Do you see the top most number change when light changes?
Call me crazy, but I am ><
I put the whole table into the automatic backlight custom levels: http://www.linux-box.nl/~sjoer/1to255/1to255.php
And it works really well with light changes, it should work even better if reset threshold can be lower (200 or maybe 100) as it will respond to bright light <> no light much better.
how did you did that?
without typing lol
This is insane..... so much trouble for such a simple task. Automatic Brightness. On winMO i used g-lite wich was satisfacatory. A have the desire for a month now. I searched from a similar soft and i didn't find. But i'm not gooing to try this much trouble for something that should be easy. Thank you.
Im sorry but....HOW do I apply this ?
Can this be applied to other roms?
I am using Pinky desire and would love to do this.

The screen minimum value is 10-255, so how can I set "1" to the first 2 levels?
I set 10, and I like the settings overall.

First off, "10 1" is redundant as you already cover that from 0 to 9. So 17 levels should be enough. Second, on the last line "10240 225" you probably meant "10240 255". Testing your settings with these modifications now. I find you have a lot of levels, probably can do with less to reduce flickering, but as I said, testing these first.
Can we use these settings in a Sense rom and if yes how?What file do we have to edit?
so useless guys.
setup max brightness and enjoy the brilliant screen.
it takes less battery than this tool to constantly check your ambient brightness.
Can someone please make a post about how to use this (and especially on Sense Roms)? So far it only shows us "which sensor-level should be what brightness" but it doesn't provide any information on how to apply it.
I assume CM either has an app for this installed (if so, please tell us WHICH so we can use it too) or a shell-script in background (if so, tell us WHICH) adjusting the settings.
Could anyone post a how-to use these settings?
Edit: Nvm, it's under: Cyanogen Settings.
Btw under "Edit other levels" you should only change the boxes that's under "Lower"? You shouldn't touch "Screen" and "Button"?
Trying this out, and will see how it goes. Only have 5 levels on my current setup, so this should be a lot smoother

Since the source code of Sense kernels is available now, would it be possible to write the tool for Sense ROMs too? You sure would do a lot of people a big favor
After using the Galaxy Nexus for two weeks, I found the screen color of the new amoled+ is much better than the Nexus S, but still inaccuracy. I'm a part-time photographer who keen on the right Gamma, color accuracy and color temperature.
So I just finished some test with such things:
Galaxy Nexus
franco Kernel 18.5 nightly(with the ColorControl from Ezekeel)
Voodoo Screen Test app
x-rite i1 Display 2 color meter
HCFR software
The test result was not so good...
Average Gammar value is about 1.9, far from the ISO stand 2.2. So the color is just too bright (I'm not saying screen brightness).
The shadow part (0-40% gray level) of 3 color curve were almost out of trim. In another words, incaauracy color balance.
As the color unbalance. The color temperature is starting from lower than 5500K to 6500K, which the ISO stand is 6500K at any color level.
I also tested the ColorControl in franco Kernel. After the adjustments, Gammar value is still bad, but I save the (most part of) color balance & color temperature in the end.
The adjustments step by step:
Make sure you have a rom/mod with /init.d autorun function.
Bye, stock rom...
Make sure you have a kernel with ColorControl function.
Such like Ezekeel, franco...Else? I don't know.
Set the screen brightness to 50%.
It's the mesurement "baseline". But why 50%?
Because, at this point the screen has a brightness about 120 Lux--also a ISO stand. So, it's very close to our desktop LCD.
Make a new file as /etc/init.d/900colorcontrol-b50
Which could be done by Root Explorer or adb.
Inside the file, type such line:
Code:
echo "-10 0 -10" > /sys/class/misc/colorcontrol/v1_offset
echo "1820000000 1900000000 2000000000" > /sys/class/misc/colorcontrol/multiplier
I choose "182 190 200" here, because the default value was about 200. Rising will increase the risk of LED Burn-in.
And, don't forget the 7 zero!!!
Just reboot & enjoy the almost right color temperature.
It's (6500±300)K at any color level in my device. Not perfect, but much better indeed.
Done, that's all I can do for you.
Thanks so much for the mod.
I'm willing to test your new calibration for the GNex color but how can I revert back to stock in case of problem ?
So I guess we can only use this modification at 50% of brightness ? If we change to auto, how could it be ?
Sorry for being a noob here, but this is compatible with any rom/kernel right? I'm currently running on AOKP Build 25 and Popcorn kernel 7.1
Thanks,
Mosh
Hi, and thank you for offering your expertise. I'm not confident in doing the above.... Can you offer a little bit more step by step?
I've played around with root explorer which I imagine is what is necessary to change these values.you lost me at the 2nd step.....
Also, is 50% necessary?
Thanks kindly,

You can change all of these settings from Franco's kernel updater program directly without modifying any files.
The OP's settings appear a little warm at first but I'm liking them so far...

Can you please add this file 900colorcontrol-b50
sooooo do i make a folder in system like this?
system/etc/init.d/900colorcontrol-b50 and then add that text above or??
Instead of making that script, can we just input those numbers into the Color Control?
-10, 0, -10 for Gamma (RGB);
182, 190, 200 for Multiplier (RGB)
Right?
Thank!
your feeling about color is exactly. Gray is dirty, it's not sync at all pixels.
I hope someone changes this by kernel - easy for me control everything
After flash franco kernel it's better more but not perfect.
If this problem is not improved, i'll buy other phone that uses Superamoled PLUS replace this one . HIZzzz
These settings look green to me

Indeed... especially settings menu looks very greenish!
But maybe I get used to it...
Edit: Maybe a typo? '-10 0 10' looks not that bad at all ;-)

And that would do absolutely nothing
SAMOLED Plus displays are identical to the SAMOLED HD displays when it comes to colors and such.
It would be better and more easy if someone was able to do an app like this one that works for the Nexus One :
http://forum.xda-developers.com/showthread.php?t=745248
I really miss this app since I've bought my Galaxy Nexus
Thanks for the info. I had mine looking very similar but with a combination of lower brightness and higher multiplier values. Nice to have it set now without the additional risk of burn in. Thanks a ton.
screen looks greenish compared to franco's recommended value, using his instead but thanks for the write up.

must be a typo in his gamma settings -10,0,10 is ALOT better (=
Great find colors are much more accurate now
These settings are way off on my device, its too green.
Today is the very first time ever for me to root an android device and thank God it run perfectly.
Now i am using AIC kernel for V500 4.4.2 stock ROM. (http://forum.xda-developers.com/showthread.php?t=2741405)
Gamma correction in it really improved screen and picture quality. (plus 8000 antutu point increase bonus)
Before, i can barely see anything in Bloodborne trailer video. (http://www.youtube.com/watch?v=G203e1HhixY)
Since i cant post in development thread, i hope i can find answers to the followings:
Is it possible to further improve gamma in the future?
Even though currently gamma is improved, but the brightness level issue still persist. Is it hardware or software issue?
Is there any possibility for brightness level improvement in the near future (kernel) update?
All in all, i really like my G Pad and really hope for the possibility to receive screen improvement update in the near future.

I heard a week or so ago through the grapevine of a version 20d coming out pretty soon. I have held off making any other changes to the AIC kernel until I see what LG did(no sense reinventing the wheel).
What brightness issue would you like changed? I know in general people think the Gpad screen is dark, but some of the AIC kernel users think the lowest brightness is too bright as well.
I think the screen is pretty bright at 100%, so for me it's a software issue. That's in 2 places, the kernel backlight driver, and the ROM brightness(think brightness slider).

Tks for the reply and also thank you very much for the kernel, it really is helping a lot!
Rather than issue, i should have worded it as G Pad having a relatively low brightness level/dim display.
Compare to my nexus 7 1st gen, G Pad at 70% brightness level still not as bright as nexus at 30%.
Actually i dont really mind it, 70-80% G Pad brightness level is my sweet spot.
However, it would be great if the number is 30% rather than 70% (i am just feeling paranoid of having big number for a display setting).
I also realized that colours (might be) a bit off, especially red that looks orange-ish.
In general display seems lean toward yellow (yellowish-white).
Wonder if this is a common thing for all unit?
Hopefully it is just a matter of colours calibration that can be solved through software update not a hardware characteristic.
I tried Screen Adjuster and added more blue and red, but i just cant seems to find the proper setting to create a whiter white or redder red...
All in all, it is nice to hear version 20d may be coming soon.
Hopefully LG will address all these screen related things.
Also, really look forward to your another great work, especially when LG get it all wrong again this time

It would be great if you could add row scheduler when you next update your kernel.

You can use Faux Clock or System Tuner to adjust the color temp and gamma.

Really...?
In that Kernel thread it states....
Add Faux Display interface (gamma control seems broken)
so does the Faux app control the gamma, even though aicjofs had noted that it seemed to be broken...?

You can find them here https://play.google.com/store/apps/details?id=com.teamkang.fauxclock and https://play.google.com/store/apps/details?id=ccc71.pmw.pro . Your best bet is to either use a calibration tool or just adjust it to your eyes.
Hello,
I am new to this forum and android tweaking. My device Asus Zenfone 2 ze551ml, is currently not rooted.
As I am a novice at this I will be getting someone else to root my device. The only reason I want to do this is to reduce the minimum brightness of the screen.
While searching for available methods on Google, I realized that most of the available apps just add an overlay or mask on the screen instead of actually dimming the hardware light intensity.
I came across an old article for another phone that mentioned changing the variable ro.lcd_min_brightness in the buil.prop file to lower the brightness at the hardware level.
Will this method work for Zenfone 2 ze551ml?
If not, is there any other method to reduce the actual light intensity of the device (and not just add a dark overlay)? Please help.
Hi i have been looking for a module for ed xposed which hopefully can control lowest brightness level. I am on Asop rom on the poco f3 and development is in early stages which means in darker areas the low brightness goes to low. It would be useful if there were a module which can set the lowest brightness to a certain value which the system cannot got lower than e.g 12% I hope this is understood and perhaps ther is already a module available for this but i cant find it.

Thankyou so much its working perfectly just what i needed.
I spoke to soon left the phone overnight and in the morning brightness very minimal again. I guess it stopped working.
