Hi,
How to change the minimal brightness level? If i wrote '4' to /sys/class/leds/lcd-backlight/brightness, it's seems darker than the minimal level in the settings. If i try to write 'ro.lcd_min_brightness=4' to /system/build.prop, but the minimal level remains at 20.
I'm using the jcsullins CM10 20130418 rom.
You could mess with your build prop but I prefer the app Root Dim, search play store for it. Be warned it allows setting the brightness below what the touchpad screen can display, so gradually adjust it down. Also allows you to set different presets, useful for night time reading.

I use an app called night mode. Love it!

For me, Root Dim seems to do the trick. I have a widget that enables Night3 when I click on it. I manually configured Night3 to be as dark as I could possibly get it.

Does anyone kno of an app that can lower the lowest brightness level? I tried screen filter but i dnt like the tint it uses n it kinda distorts the quality of images and videos shown. I tried googling stll no luck. The lowest brightness level is still brite at nite.....
Have you tried turning off the Auto brightness feature and then manually reducing the brightness in the display options?
If you turn off Auto Brightness in your Display Settings, you can run your finger left or right along the top slide-down menu bar (the one that displays time, battery, signal, etc) to decrease or increase the screen brightness.
Srry i meant lowering the brightness lower than the lowest level limit. The screen is still to brite for me at the lowest level at nite.

Use this software from Android Market,
https://market.android.com/details?id=com.curvefish.widgets.brightnesslevel&feature=search_result
Android Os will report you zero brightness when you change it in settings, but still it has 8% brightness enabled, so the above software will help you to pulling it back to original 0%
Even better than that, I remember supercurio (iirc, or was it hardcore?) hacked the SGS kernel to enable to an even lower brightness setting ages ago. However I haven't seen this hack integrated into any kernels for ages (unless I'm missing something and it's already there)
Hardcore's Speedmod K13E kernel for 2.2.1 has a super low brightness level
Try the dimmer app, it is better than screen filter, not as grainy.

any oficial rom with lowest minimal brightness?
thanks
I'm sorry to bring this up again...
I'm testing out the last build teamhacksung's CM9 and it came with a bunch of options to optimize the brightness.
Although I've been experimenting on this options for quite a while, the brightness is very irregular. At one moment is very dark and for no reason the brightness comes back up while I'm in total darkness.
Do you have any idea of what's causing this?
I get this as well. Also, the screen will auto-dim after a short time of inactivity. How to control this?

Also, I have a friend with the same software as me, everything the same and his Galaxy S gets much darker than mine. Even when we have them side by side.
Try Semaphore's kernel on THS ICS. It has its own auto brightness that works well and has a Dark setting.
That said, I still use screen filter on top of that in darkness.

Semaphore's kernel disables the BLN for me.
What I did was...
In the definitions put the dim level to 6. And then I added a button in the notification bar for brightness and I gave it the automatic and dim options.
That way when I'm inside doors I put it to dim and when I'm outside I change it to automatic.

In the same ROM as mine? Can you tell me where are the configurations for the BLN after installing the Semaphore kernel?
Has anyone else noticed their D3 on stock ROM min brightness is 11%? I noticed since getting my D3 that it has always been pretty bright, even at min brightness level. And using the brightness toggle from Beautiful Widgets, I saw that the two options were 11% and 100%. Is this just the widget, or is the stock ROM set up to keep brightness at this minimum level?
I use my phone in the dark a lot and it kills my eyes to look at it for too long, so I'm wondering if anyone knows how to get the brightness down any lower without switching to a custom ROM. I am rooted, of course.
Thanks for any ideas/solutions.

Brightness Widget Backlight, in the market should work. It's has configurable steps that can go down to 1%. I'm using it on CM7 and can get it lower than the lowest brightness setting.
You can lower it with Quick Settings, but a reboot changes it back. The lower brightness appears to be used when the display dims from inactivity. If you are already on the lowest factory brightness setting it can still dim some more. Thats the only purpose I see of it.
I use Brightness Level from the market and it allows you to go lower than stock does. I believe that it keeps settings after reboot as well.
Sweet, awesome replies.
Lookup screen filter, and should be on the market if I remember correctly.

I just installed and tried Brightness Level and it doesn't allow brightness levels to go below the lowest stock level. I see no purpose to that widget since the Power Widget for android allows brightness level adjustment.
I'd love something that allows for true adjustment from 1% to 100% on the stock ROM.

Screen filter rocks - been using it since I got my D3 back in November.
It's a great app that dims the screen and make it easier for the eyes, but I found one major bug today. While the filter is on, you wouldn't be able to install any apk's. The button is there, but you can't click it, you can only cancel. Basically it feels like your touchscreen has a dead spot right on the button.
Anyways I was panicking thinking my nexus 7 went crazy, and I uninstalled a lot of apps just to find the culprit. So this is just hoping no one else panic like I did. I also already emailed the developer.
1. It was discussed before, use search.
2. Stop using that crappy app and use https://play.google.com/store/apps/details?id=mobi.omegacentauri.ScreenDim.Full for reading.

Um, I use that app, but it doesn't dim it lower than the system does. I just use it to quickly adjust the brightness instead of going into the settings.
EDIT: Yeah, I'm an idiot. That's not the same app I use. Just looks very, very similar. None the less, I tried the free version and it did not get noticeably dimmer.
I'm using the app '2x battery' which also has a screen filter feature, no problems in use, also seeing as I paid up for it it allows to filter by colours, so have set it to fade in a purply filter which basically reduces the green tinge my screen has, took some fiddling to get nice result but got double whammy of screen a little dimmer for indoor use and better colour balance, no lag or Faff so far.
Free version just allows a standard dimmer fine for most scenarios

Well I think screen filter is simple and it e works very well. I'm going to continue to use it, just have to turn it off if I'm installing apk's
I use 'Night Mode'

I am using screen filter with Sony bravia engine and it all works great. screen filter still gets blurry at lower dimness though.
Try Root dim or Voodoo display filter. Both are great for the purpose.

This thread I'm only taking about the specific app named "screen filter" though, just so people won't get confused. It works great btw, the screen can get as dim as you want.

The app you want to use is Custom Auto Brightness by Dmitry Matuzko. It lets you set brightness levels based on your light sensor and has the option to use screen brightnesses lower than the programmed limit without using overlays. Obviously you won't be able to go lower than the hardwares limit, but in most cases the manufacturer sets the software limit much higher than the hardware limit.
Onibabar UpdateUpdate
Thanks for posting this thread! I don't even use a "screen filtering" app BUT I was having the same issue were my INSTALL BUTTON was no longer working, and because of this thread I now knew at what sort of 3rd party apps to start looking at. At first I thought it was the ROM I was on, then I thought it was only on 4.2.2 ROMs since it happened on more then one of my setups, and finally, I thought it was a Mod I always use, that gives my phone inverted apps. In the end though, it turned out to be the latest update to the Onibabar app from the Play Store. Its a app that places a battery bar on your screen and the latest update allows it to be positioned going down on either the right or left side of the screen, in addition to the top or bottom. So whenever its set to go on the left or right side, it disables the INSTALL BUTTON when attempting to install an app from a file explorer...
So I have a rooted ATT atrix.
The screen brightness is awesome for some things but way too bright for others.
My question: Is there some way to lower the brightness settings even further than the lowest stock brightness?
I know that on certain custom roms you can go into the sys files using ES Explorer and change values there, but I'm not an expert in any sense,
I would like to keep the automatic brightness adjustment intact, just lower the range of brightness
If I navigate to /sys/class/backlight/lcd-backlight/ then I can edit the file "brightness" to value of 1 which lowers the brightness significantly. The default minimum value seems to be 21.
When I do edit this value, then allow the screen to auto adjust brightness, the value goes back to 21.
I don't know where to set the range for the auto brightness.
I think lowering the range will save my eyes at night and also potentially save some serious battery

I guess using this app will get what I want done. it'll just take some personal calibration

I use my Z3C at night quite often and find that the backlighting is too bright even turned all the way down. The adaptive lighting option does not bring it bright enough durring daylight use if left un the low setting. Is there any way to adjust the backlight other than a 3rd party app?

Do you mean other than the brightness slider?
Install lux and set it to adjust brightness automatically depending on ambiant light.
Set it to -10 or 5% with 1 lux and 100% with 100. Etc. It take time to adjust it but will save your eyes and battery.
Donation isn't necessary but bring some good options.
Works like default adaptive brightness but with more steps (if you desire), darker or lighter...

Thanks man, will look into that! using Twilight now, it is waaaay to complicated for what i want.

After a few days with Lux, it is much better. It allows the screen to dim and brighten way past stock settings. I really like the night filter mode. When i am outside and check my phone i am no longer getting blasted by a spotlight bright screen!
