Little background: somewhere in kernel code or some other core module of the operation system manufacturers or ROM creators set minimum brightness value for the device. This value was in some of my other devices called min_brightness. I remember faintly that I was able to set the value by running some script in Init.d. Unfortunately I did it several years ago for my other device and cannot remember the details.
The minimum brightness in Colt OS is 31 and seems to be similar other roms, which I tried.
Another option to set the value is Xposed module called Minimum Brightness. Unfortunately it has zero effect on my device. forum.xda-developers.com/xposed/modules/mod-minimum-brightness-t2993161/amp/
Another option is to use app called Brightness Tweak, which does its job somewhat but the result is not exactly desirable. The problem is that it makes the brightness curve not smooth and setting semi-bright values is impossible. It is however able to set the value to 1. https://forum.xda-developers.com/android/apps-games/app-brightness-tweak-t3339579
By the way, I find screen filter apps in adequate because they reduce contrast and add complexity to setting the brightness. Setting minimum brightness affects swipe status bar and brightness sliders as well as auto brightness functionalities. In addition MX Player.

Try to use "ScreenDim" app
Thanks for the suggestion. I tried the app, but in my opinion the brightness adjustment method is very convenient. The is no slider in notification or sliding status bar. Also the min brightness is not adjusted globally so other brightness adjustment method are unaffected.
Hi, @wwwwe did you actually solve the problem?

Have you tried light control app?
No + the phone is broken already. It wont keep charge anymore.

Is there any way to make set display's brightness level lower than slider in settings allows?
Why?
1) SGS's display got so much brightness and contrast that in low (or zero) light conditions it is simply too bright! It hurts eyes.
2) It might severely improve battery life.
Any gurus around? ^^
echo # > /sys/devices/platform/s3cfb/spi_gpio.3/spi3.0/backlight/s5p_bl/brightness
brightness to 0
If i remember, real mini is 8, max 255, i use Brightness level from Curvefish ( Market ), it seems to be the lowest i can get, an it's a 1X1 widget, not that horrible.
Dimmer Night mode , Market too, is another way to go.
Twice are free.
Thanks, working as intended
The best solution would be to allow 'auto' setting to go that low.

Yup even quick settings (free) from market allows to go uptil 18.
i use Dimmer. brightness is 10.
I use extended controls and it has multiple options to control brightness or switch between user and auto brightness settings. Not sure it goes lower than stock but i tested it today and i can get 7 hours of almost nonstop use out of a full battery. Thats a mix between navigation internet and calls. Thats good enouh for me.

From 1 to 17 theres no difference in brightness. 0 is screen off, 18 is lowest brightness,.... and so on up to 255.
I've seen a few references to making the "backlight" (brightness) lower than standard but I haven't found what can do this yet.. I don't need/care about a widget, I want to use it programatically in Tasker to say set the brightness to minimal or maximal in a sane fashion... Changing it in Tasker seems to have Android induced limitations.
Also, perhaps separately, would be nice to have a program which you can adjust the auto brightness sensitivity and have more control over it.
Thanks for any suggestions!
There is an app in CM6 that does this, it's really good, you set screen brightness for different light conditions. It can be set lower than standard brightness and you can have as many different brightness levels as you want.
I haven't been able to find this to use with any other ROMS, but would really love for it to be included in Enoms Rom.
The description of this app on the CM6 changelog is
Configurable brightness sensor - Jonas Larsson

Aha, yeah now that I searched for his name I see a few other requests for this outside of CM6... Maybe someday.
Hi
The "Adapt to lighting conditions" is checked, but it doesn't really adapt. I have to manually change the slider to adjust brightness.
Looks like a bug. Not sure if there are any other settings to make.
Is this a known issue? Any workarounds?
Thanks.
Farhad.
The slider sets the maximum brightness of the screen, not the minimum. Hence, in order for the auto adjust to work, set it to the max and tick the check-box.

seems to work more like a brightness scale kind of thing. not only sets max, but minimum as well.
it'll always adjust when the box is ticked, but the slider determines how bright or dark biased it is.
It's a sliding window of brightness ranges, which should be good news to anyone who's felt that autobrightness on other phones swings too far in either direction. Now you can customize to your own taste.
Personally the sweet spot for me with good compromise between use in low light indoors, daylight and office lights is about 25% - the slider button just above the second "g" in "lighting conditions"
Remember though that changing White Balance settings will darken the display, and you'll need to boost brightness to get decent contrast again.
Use Lux Lite from the playstore. It lets you individually "link" a specific brightness level to a specific lighting condition, which the app then remembers and automates.

What do you mean "Source"?
That's how it work[s|ed] on my Xperia U, Xperia M, Xperia SP and now on Xperia Z3C.
Not proof enough?
It works, but doesn't work well. When I wake up at night the brightness level goes lower but not nearly low enough. I have to manually reduce the brightness to the lowest level. When the day starts, I have to manually increase the brightness. Not ideal, not a deal breaker either. Hopefully Sony addresses in the next update.

Totally agree, Im using lux to improve the brightess auto adjust....
hello. i am having trouble with this option. on some ROM's it is easy enough to disable. but with others, disabling it causes the screen to go darker then 0 brightness.
i find this and was changing this... /sys/devices/mdss_dsi_panel/cabc
in that file is a value you can change between 1 and 0. 1 being the default on position.
all-in-all, i would just like to somehow disable CABC and also keep brightness control not going darker then 0. manually settings the brightness while CABC is set to 0 does nothing. it is possible to increase brightness by using an app/mod to increase minimal brightness levels, but that is only a work around.
at the moment i am using [ROM] eXistenZ Premium Final 9.5.5 Z1 5.1.1 .236 Lollipop By XsHaWnX.
any help appreciated

Looks like something you should discuss with the rom developer.
Heavily tuned roms tend to show strange behavior in some cases - this seems to be one of them.
okay. well, i will send a message. thank you
Hi,
Not sure where the correct place is for this, so thought that I'd put it here.
I am looking for an app that controls brightness. I like the brightness of my phones to be dialed down to around 40%. I find it most comfortable for my eyes. Yet when it is bright out, I need to make the screen brighter. This means that I need to go in and manually adjust the brightness. I don't like to have the phone set to automatically adjust the brightness.
I'd like to find an app that allows adjusting brightness by icon. I don't want one that has one icon that toggles through a bunch of preset brightness levels. Instead, I want an app that can have different icons for different brightness levels. That way, if I wanted to toggle the brightness to 60%, I could tap an icon that does that. Then I could have an icon set for 30% to set it back.
Anyone know of an app that does this?

Lux, if properly configured, could do that for you.
I think I understand what you're going for. I use Power Toggles (Dev: Painless Apps), and one of the toggles on the widget is for brightness and I have it set to 3 settings when I touch it; 20%, 40% and 100%. It's not possible to set each new brightness widget for individual brightness presets, unfortunately, but I don't see how it would be difficult to just make some predetermined settings for your brightness.
By now you should have a pretty firm idea on what level of brightness you prefer throughout your day so maybe you can use this app and have 2, 3 or more presets. It's really simple to use, I have it set to 3 settings and touching the widget to get to the brightness I want at that moment is super quick and not difficult at all.
You can see in the screenshot I use the widget at the top on my home page. Brightness is among the other toggles I use on a regular basis. Much quicker to turn on and off things, IMO. It's right there on my home screen so I don't have to pull my notification window down. I hope this helps.
I just use Auto Brightness setting. I set the brightness slider at 40% and the phone will auto-adjust the screen to keep it at a relative 40 indoors and outdoors.
I think this is what you're looking for:
