[Q] Auto-brightness values - Desire HD Q&A, Help & Troubleshooting

Hi everybody
I'm a Revolution HD (5.1.11) user, and I have the Unity V3 kernel.
I was wondering if there's a way to modify the auto-brightness values: with stock settings it never reaches the lowest value, and in complete darkness the screen of my DHD is always too bright.
I'd like it to vary between the maximum and (nearly) the minimum values.
Is there a fix, or a way ot modify the file containing these settings?
Thanks in advance

Up! Isn't there anything to solve my problem?

[Q] setcpu settings

Hi All.
In your opinion, what are the best settings for htc desire (including advanced settings and perflock) please ?
Sent from my HTC Desire using XDA App
Yeah would like to know also the best settings.
Set Max to Max
Set on boot: on
Leave the rest alone

Doesn't that defeat the object?
Having it on Max (as it originally was) would make no change at all.
Idea is to slow the processor down in certain circumstances and help reduce power and battery drainage.

Undervolt reduces power usage, not underclock.
Non-sense roms can be overclocked but you have to set it. Ie set it to Max.
whats this about using a text file on the memory card to make it run better?

[TWEAK] Automatic Brightness levels!

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.

yes and for stock roms please
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

[Tips] Screen Color Calibration for the Galaxy Nexus

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.

Great find colors are much more accurate now
These settings are way off on my device, its too green.

[MOD] Lower Autobrighntess values - battery saver

For people that want to save some battery juice and think that the autobrighntess values are too high...I got the right mod for you.
I lowered the autobrighntess values in framework-res:
old:
Code:
<integer-array name="config_autoBrightnessLcdBacklightValues">
<item>63</item>
<item>63</item>
<item>63</item>
<item>96</item>
<item>130</item>
<item>143</item>
<item>171</item>
<item>199</item>
<item>227</item>
<item>255</item>
</integer-array>
new:
Code:
<integer-array name="config_autoBrightnessLcdBacklightValues">
<item>1</item>
<item>11</item>
<item>23</item>
<item>35</item>
<item>48</item>
<item>55</item>
<item>80</item>
<item>150</item>
<item>200</item>
<item>255</item>
</integer-array>
People who dont know what this mod is doing, a small explanation.
When you got your brighntess on "automatic" your screen brighntess will be set regarding the value of you brighntess sensor.
So if its dark outside = low screen brighntess,
if its bright outside = high screen brighntess.
But in my opinion the brighntess states of the automatic screen brighntess are far too high and wastes battery.
When you also compare both first values in the two arrays you see that the minimum autobrighntess value was at 63 as default.
So when its completly dark in your room/outside your screen brighntness is brighter then it has to be.
...so you have maybe already noticed that the manual brighntess you can yet is far lower then the minimum autobrighntess value.
Its a flashable zip and compatible with Leedroid Tweaks.
In the next version of Leedroid Tweaks there will be a toggle to choose different autobrighntess arrays:
normal, low, lowest.
But for now you can use this zip with my prefered values.
hf:
Pls make a backup, before flashing this zip.

Yeah, but still need to test if that values are okay for daily use.
Could be that a few steps are too low, so wou wouldlnt see the screen as good when its bright outside.
Just tested it my office..will seeover teh next two days if that values are okay (-:
Will keep you posted, weather here is awful atm, so can't test in sunny conditions but inside is fine.

Thanks..I'll try it later..
This mod seems a good idea.
Have only been using my phone for a day or so, but the screen does seems to drain the battery somewhat. Am hopeful that your mod will help.
It's a good idea to have different profile with LeeDroid tweaks.
Already liking this mod, many thanks

great job, there would be possibility of a zip to restore the original values​​?, thank you very much.
great mod, i like your new settings. i tried your new setings today afternoon in my car, the display was bright enough for me.
more outdoor usage this weekend, i will tell you if the brighness is too low.
it's working perfect in low/no light, just the right brightness for me
however, during the bright day light this afternoon it was constantly changing brightness, one second very bright, 2nd second very dark, third second somewhere in between then start the cycle again one second very bright, 2nd second....
but seeing that no one else has mentioned about this then i conclude it must be something that i've done wrong... again... hehe (i'm gonna keep using tomorrow and see how it behaves)
keep up the good work matey and take ur sweet time before getting married, as someone once said 'Marry in haste, repent at leisure'
Thanks.
Did you perhaps find a solution for the backlight of the menu buttons.
I get the feeling they are not lighting up correctly.
When iam in my backyard in the dark the buttons don't light up, till you cover the sensor complete.
Others are having the same problem?
Can you tweak those values too?

you could just replace the framework-res with the one of your preferred rom in the flashable zip. or when your use leedroid tweaks use the framework-res of that.
At work at, can provide two flashable zips after work.

it will work on each rom, which is rooted and deodexed.
...not really sure about the deoxed one..make a cwm backup and try it (-:
it's a bright sunny afternoon here and your auto brightness settings are working perfect today, must have been the gremlins yesterday
i've made a bunch of transition effects including ics, bounce, flip etc using your zip to flash them, if you want to test them and use them you are more than welcome (i've downloaded to my dropbox, so pm me if you're interested)
