LCD Backlight - 8125, K-JAM, P4300, MDA Vario General

Are there any settings in the registry that control the actuall brightness level of the 4 positions on the LCD brightness control? I find that the dimmest setting is still too bright for my use in a completely dark envrioment.

Automatic Brightness

Here's my dilemma... I like saving battery by setting my brightness level lower than the automatic setting (since the screen still looks great anyway), but I would like it if I didn't have to go into my settings manually to change the brightness level so that I can see the screen when in direct sunlight. Is there any way someone could develop a mod to have the automatic brightness, but about 20% dimmer? I don't know if it's possible, but it would be pretty awesome.

I have my screen set pretty dim, and use the Power widget to crank up the brightness if I go outside.
You can also you the "Screen Filter' app to make the screen x% darker than the current setting. (which even allows you to make it darker than the dimmest brightness settting, which is really nice on the batteries.)

I am current searching for the same thing.
temp solution is to Market > Dimmer (night mode) by geekyouup
It toggles auto brightness and sets back light to min. when on. click once, screen goes super dark, click it again, auto brightness take over. handy. (put it up to status bar w/ bar control and you can get to it when ever)
Problem with auto brightness right now is at it's lowest setting, the back light is still at about 25%. there is gotta be a way to change that in the settings.apk
or better yet, have an option to set your own ambient light to lcd brightness ratio for the auto brightness
option to set own ambient light ratio?

I'm search for this also. I believe you can adjust this in CM7 but is there is a way to do this that is not ROM specific? I'm currently using RoyalGlacier with Faux123 kernel and I find the auto brightness setting for dim ambient to be too bright and the bright ambient to be not bright enough.

Lowering Brightness

The "low" brightness is way too bright for me. Microsoft is nice enough to introduced 30 levels of volume but offering just 3 levels of brightness is pretty dumb.
Anyways I was looking through registry hack and I found the MinBrightness and MaxBrightness setting. Originally I set it to "manual" and "low" in the brightness setting. Then I checked the registry and the Min and Max is 0 and 19 respectively.
I changed the Max to 0, and it APPEARED to be dimmer than before. I went back to the Setting -> Brightness and now my brightness level is shown as "Medium", Auto adjust set to off. Both of them are grey out so that I cannot change it, I supposed the setting screen read an unsupported combination and freaked out. I wonder if anyone else tried this, or this is just my placebo effect?
I thought I was the only one having this problem.
Hopefully there will a solution regarding this issue.
I wonder if I can use privacy screen to lower the brightness, or even those tinted window screen from home depot.
So where to tweak this in registry?

How Can I Control Contrast & Backlight Programmatically

I need to develop an Android app which should have options to control LED brightness, backlight and contrast. From various documentation on internet, I found ways to control the brightness, but couldn't find anything about backlight and contrast. First of all, in Android devices, isn't brightness and backlight the same? Also, how can I control these two from code? Please let me know your suggestions.
Brightness can be changed by setting the screenBrightness member of the window's LayoutParams (fetched with getAttributes()). It ranges from 0-1, or set to -1 to use the default brightness set by the user in display settings.
However, even at brightness level of 0, the backlight remains on; it's just dim.
I've been looking for a way to turn the backlight off completely, without success. I know it's possible because there is an app called "Screen Backllight OFF" that does it (device must be rooted). I've read various suggestions on using WakeLocks, but I want the device and my app to remain awake and active; all I want to do is temporarily turn off the backlight.
Does anyone know how to turn off the backlight?

How to control always on screen brightness

Is it possible to control the brightness of the always on screen separately?

Auto-boosted brightness question

The brightness that allows the phone to get more bright than what manual maximum brightness settings allow under high ambient conditions. Is it possible to enable this level of brightness on manual maximum brightness constantly with root and tweaking a certain script? I really like whiter whites.
No one even knows how to remotely answer this question?
