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 ><

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?

The screen minimum value is 10-255, so how can I set "1" to the first 2 levels? :confused:

I set 10, and I like the settings overall. :D

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.

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
