How to make screen dimmer

I often use the phone to read in bed with the lights off. The screen is still way to bright even set to 0%. Anyone know how to dim it further?

If you're using the Aldiko ebook reader, just set the background color to black and set the text color to grey or some other dull color.

on 1% mine is very dim even in pitch black darkness, you must have sensitive eyes

I wonder if mine is behaving normally. I have set it to Auto adjust off, and slider to 0%, and it is still readable in bright light (probably daylight).

Sunglasses

Maybe you have the same problem described here?

Get the Dimmer app from the market, it drops the screen "0%" brightness from 18% default to 10% and I find it perfect.

I just tested 3 apps on the market. Dimmer is good, but quite simplistic. Varies the brightness between "10" and whatever you have it set at. Apparently Android's idea of 0% is "18".
I also tried "Brightness Level" which gives a bit more control and allows you to set 0%, 25%, 75%, 100% and Auto. 0% setting in Brightness Level appears to be the same as the level of "10" that Dimmer allows. The program gives a percentage indicator of brightness.
Brighterrific may be very marginally 'better' at dimming the screen. It allows you to set a minimum and maximum brightness. If I set it to 0% in the program and then compare, it says the brightness has been set to -3% (according to the brightness percentage indicator in "Brightness Level"). The difference between 0 and -3 isn't very visible to me, but maybe it'll save slightly more battery life. I also noticed that clicking on Dimmer won't work after setting it to a level of -3%; maybe because the program doesn't recognise a level lower than it's default lowest level of "10"?
Obviously lower levels must be possible if Dimmer indicates that it's lowest level has a value of 10; it must be possible to set it to 0 or 1 somehow. Needless to say, if anyone finds a program which can set -30% let me know

Thanks folks. I have installed Dimmer and I am happy with the screen brightness.

CM6 light sensor levels discussion

What are your observations, settings, and thoughts about tweaking CM6's light sensor levels?
(Settings > CyanogenMod settings > User interface > Automatic backlight > Edit other levels...)
Observations...
I've noticed that the sensor seems to only pick up light levels only at specific intervals (raw values, not filtered)... for me that was 160 (never went lower), 640, 1280, 2600, and 10240.
When it comes to lowest level the sensor reads it isn't really that low. I can be sitting at my lightly lit room or in complete darkness and 160 is the reading I get. Also, the highest level the sensor reads isn't really that high. I can be standing outside on an overcast day or in full sunlight and 10240 is what I get.
Thoughts...
Basically, given the observed intervals above, I have been trying to find a reasonable screen brightness at each level, where the screen is bright and doesn't appear washed out, but isn't unnecessarily bright either.
What is the lowest screen brightness that looks descent when the light sensor reads 160, 640, 1280, etc?
Where I'm at...
upto 160 - 35
upto 640 - 50
upto 1280 - 75
upto 2600 - 100
upto 10240 - 125
I really would like to tweak the higher levels, but I'm having a more difficult time finding lighting that is in those ranges. I also setup the power control widget to toggle the brightness between Auto>Dim>75%>100% to cover the lower light levels not picked up (below 160) and the higher levels not picked up (above 10240).
Observations? Settings? Thoughts?

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?

[solved] brigthnes levels

i see lot's of screen shots of the cyanogen brightness settings were the ligth sensor in at levels such as 30, and the screen level is configured to level 1 or 5.
mine, the sensor is always >200 and the screen level can't be lower than 35 (if i type 5, after clicking OK, it became 35)
is that normal? anyway to make the screen darker?
also, i assume the button light can't be changed right? because it does not change on mine at all.

Is this on CM7? There's a setting in there to set the lower limit, Screen Dim Level as far as I can remember. Its probably set to 35 hence you cannot set it any lower in levels. Set it to something lower like 1
Then go into "Edit Other Levels" and set your various levels in there. You can set the button setting to 0 for off, or 255 for on.
The Nexus One actually has 9 different levels for the light sensor, so you only need to set values for these.
10 - 160 - 225 - 320 - 640 - 1280 - 2600 - 5800 -8000
HTH.
PS this is one of the very useful options I really miss in ICS ROMS!

[Q] automatic backlight works only with max. 6 levels

hello, I'm using CM10 quarx ROM from 9.4.2013 (this one) and I have problems using more then 6 auto backlight levels. When I set the number of levels higher than 6 levels the display brightness won't change to this setting, e.g.
level 6: 4000 - 4001 200 0
level 7: 4001 - ....... 240 0
Means within the full sun (sensor level over 9000) backlight wont change from 200 to 240. The same problem do I have with more then 7 levels. All settings between level 1 and 6 are working fine, all other levels above will be ignored.
Here is mentioned that it's not working at all with all CM10-ROMs. It's fixed in CM10.1 ROMs. But I could edit a xml-file, to enhance the backlight steps manually. Do somebody know which xml-file I have to edit to reach my goal? What's the name of the file and where can I find it?
