I know this is possible in CM9's display settings, but I'm currently running AOKP. Is there any other way to lower the minimum screen brightness?
I've given Tasker root permissions, approved it as a device administrator, and approved it as an accessibility service. Still, when I use a task to lower the brightness to very low levels, the brightness will only hold for a fraction of a second before it ramps up to the factory minimum.
So is there some system component I can modify to allow lower brightness, or is this only available as a ROM control like in CM9?

FWIW the lowest possible brightness setting can't be altered via the CM9 settings, only the auto brightness levels, both sensor input levels ("bins") and the brightness level associated with that input/bin. The minimum value of 19 for the lowest slot can't be lowered further. There are other display parameters (related to brightness) that can also be altered in the CM9 settings, but it won't accept a value less than 19.
Edit: I see from a link in your sig that you're familiar with the custom levels
Yes we can do it in the frameworks to go lower than 19. I did it on other phones. I'm not sure why it hasnt been done yet for nexus, and ive been too lazy myself.
But we can even take it down to zero or 4-5 etc so its much dimmer at night. Its on my to do list.
Also i posted some kernel code in a similar thread where this question was already asked. But mod the framework is much quicker.

I should have clarified more clearly that my post above was regarding doing it via the CM settings.
I'll mod mine...at some point...but like you, too lazy for something that won't blow me away.
You want this app, works great https://play.google.com/store/apps/...yZy5wcm9qZWN0dm9vZG9vLmRpc3BsYXlmaWx0ZXIiXQ..

I'm an idiot; I just found it in AOKP. It's in the custom backlight settings.
My experience does not mirror you guys. When I decrease the "screen dim level" in the custom brightness settings, it applies globally. I just did it in AOKP the same way I used to in CM9 and now with Tasker I've taken the screen all the way down to 1
Is there any way to decrease the minimum brightness on stock?

I've used a similar app called Screen Filter. My only problem with these types of apps is that I find the black/gray filter they use greatly decreases contrast at low brightness levels (more so than a "true" brightness level at an equivalent setting). Still, if you are running a setup in which they are your only option, they certainly beat having nothing.
The problem with using a screen filter is that it limits the maximum brightness when in sunlight.
I only want to affect the minimum as it is too bright.
Has anyone been able to do this on a stock rom? I too think that the minimum brightness is too high, but I don't want to use the above linked program because it also affects the maximum brightness too. I would like to be able to set custom light levels as per cm9/cm10 and pretty much any custom ROM right now, albeit with my stock ROM. Any flashable zips out there?
Cheers,
Dan
I find the dimmest screen toggle still too bright. I find it embarrassing to use in dark public spaces.
Is there a way to dim the screen even more?
Download the screen filter app from the play store. Literally puts a filter effect on the screen to make it appear darker making it much easier to use in the dark.
Yes its possible to take the screen much lower, but we have to edit the framework. Nobody had done this mod yet for some reason.
CM9 has the ability to change the screen lowest settings built in

+1. I use Screen Filter also, it's uber handy for reading at night when the light seems too bright. If you've got hardkeys like I had on my Desire, you can even turn them off.
i wrote a tutorial on how you can mod the frameworks apk. it's very easy and you can change the brightness levels to anything you want. here's the thread
screen filter only puts a transparent layer on the screen and messes with the colors. modding the frameworks will lower default brightness to any level you want. you can raise it too if you like.
Thanks for all the ideas. I went with the easiest one, Screen Filter.
AOKP also has an option to reduce screen brightness...

Great work, I've been wondering why nobody did this mod yet for the nexus. I made that same mod on my atrix, using the sgs2 thread as well. But I've been too lazy to do it for nexus.
The above mod is the best option. Screen filter doesn't achieve the same results. The above mod reduces power draw as well when on the lower brightness setting of 5 or so. Screen filter just hides the higher brightness but has same power draw.

That would be correct for back-lit screens. For the Galaxy Nexus screen, though, Screen Filter does help reducing power draw as a darker screen content = lower brightness.
I used to use SF for quite a while until I got fed up of it causing stutters to most animations. After thorough examination I concluded that the Nexus's GPU is the culprit. For some reason it just doesn't like multiple graphics being updated at once. Modding the overlay XML allows it to run at full speed.
Can anyone confirm the same reduced framerate issue?. It's also the reason why some ROMs include a setting to remove the navigation buttons glow. I tested with CM9 on the SGS2 and experienced none of the stutters in cases where the GN would. Another example: sliding between sections (comments, ralated, etc.) in YouTube is laggy iff the video is playing.

Agreed, GPU just isn't good enough. I hate the lag with the button glow animations on!
I use an app called root dim, it's really useful. Let's you use a brightness level of 1, which is really quite dim. Free, too.

Thanks for the tip, on the Galaxy Nexus it's possible to set the brightness to 0 by writing to /sys/class/backlight/*/brightness but the brightness is checked and reset to the minimum (default 10) every time the screen is turned on. I guess Root Dim works to the same effect so it runs as a system service. Still, it'd be an awesome addition for people who haven't bothered to mod.

Screen filter may reduce power. But amoled screens save power with lower brightness. There is no difference between lcd vs led on this issue. And modifying the framework to bring min brightness down to 5 rather than 15 saves much more power than screen filter. Its no contest. This isn't different from lcd in this case.

Yes we can write to that sysfs file, but it gets reset. The mod to the frameworks incorporates that backlight file so its now able to go down to 1, 2, 5, or whatever you want. It makes it now stock, so you are no longer capped at 10 (actually I think 15 is the cap I see). But that mod is just removing this cap and making it lower to whatever you want. Stock.
So no extra app is needed. No additional tweak. It now makes the stock brightness able to go down to 1 by itself whenever it needs.
The lowest brightness setting is not dim enough for me in low light conditions so I've been looking to alter it.
After reading around the capabilities of some apps it seems that they only add an overlay which reduces contrast. I would much prefer to do it natively.
I then realised that the AOKP ROM has this functionality!
However, I can't seem to get it to work.
Settings>Display>Custom backlight settings
Changing the screen dim level doesn't seem to change anything for me.
Can anyone offer some tips or advice?
Thanks
Works fine for me. I know it doesn't help your problem any...

Does your display dim more when you select a lower than default value or did you have to change something else?
Did you change the corresponding value in "Edit Other Levels" as well (if you're on auto brightness)? Not on AOKP, but mine is fully functional both on manual, and auto.
Their implementation is the same as CM9 (which is nearly identical, if not the same as the CM7 implementation).
Edit: just a thought, not sure if the AOKP status bar brightness slider is hardcoded to a certain minimum level? Are the results the same if you adjust your brightness via the Settings>Display>Brightness slider?
Settings>Rom Control>Performance>color multipliers.
Drag the three bars all the way down.
As far as your problem...
Are you on auto brightness?
And have you adjusted the "Dim Level" prior to adjusting the screen levels?
(Dim Level is the level your screen dims to after not touching it for 15 seconds or whatever).

Screen dim level is the minimum brightness value attainable (I lower mine to 12 so I can enter a screen value of 12 in my custom levels), but also does correspond to what you mentioned.
Another AOKP user expressed similar concerns but found an app called Root Dim or something that solved his problem.

The implementation must be still broken then; haven't tested the latest AOKP releases. Root dim apps tend to create lag.
Implementation works perfectly here.

I select a lower than normal default brightness, and it appears to just work. The auto brightness decreases, which is what i was looking for at night, and also the overall min brightness decreases. The max brightness seems unaffected...
remember when making these changes you do have to save and apply. many people forget that step.

Lol.
And no offense taken at all, man.
And me personally, I just use 5 levels.
One that goes all the way to 600[whateverambientlightismeasuredby] and a screen level of 5.
This keeps my phone from dicking about with it's brightness when I'm indoors...and I have no problem reading it. I don't mind a super-dim screen in general.
The remaining levels I ramp up fairly aggressively for two "by a window" scenarios...
And outside.

I add 2 levels for the high end, and reduce the other brightness levels considerably. Ultimately I usually end up with the perfect'ish level for most scenarios. I hate having to adjust brightness the old fashioned way

Yeah, I know an app could potentially solve the problem but I don't like using 3rd party apps when the solution can be more elegantly achieved using native tweaks.

Could you send me a screenshot of your custom levels, that sounds like the exact thing I'm after - a dimmer screen in general, and having a lower min brightness.
So am I correct in thinking that you need to lower the dim value in order to set lower values in the custom levels?
Whenever I use S Note, the brightness always seems to go up and I can't change it, anyone know how to adjust it.?

Mine starts with reduced intensity, if I selected reduced intensity as a general setting. Do you use (intensity) auto-settings of any kind in the general / Touchwiz settings? Or reading mode?

That is actually a great suggestion. It does not switch to full brightness when system auto brightness is disabled.

I always disable those 'helpful' features. Just include the brightness control in your status bar, set Adapt display to off, Screen mode to "Movie", switch off Reading mode, all Smart screen features to "off" etc. (unless you prefer otherwise)
I still get a very bright screen that doesn't respond to the brightness slider. Any fix for this or are all users of S Note using it at this brightness?
I use Lux Auto Brightness (there is also a free version), to overwrite Samsung control. It allows different settings for different apps.
Thanks. Will check that out.

I had same issue. First I turned off auto brightness before starting s note. Adjust brightness, then run s note should keep the brightness the same.
It help the situation but not a permanent solution. Hope Samsung can fix it ASAP.
I saw the phone in a store today and wanted to buy it. But got annoyed that the smallest screen scaling option is still bigger than my p20 pro and feels like a waste of screen real estate.
Does anyone know of a way to make things on screen look smaller without rooting?
connect to adb and use wm size option. whatever size you set make sure aspect ratio is same as original device. it works better than wm density.
It’s even simpler than that. There are adjustments in display as well the option in developer options to adjust dpi.

You can change the minimum width setting to a higher number in developer options but it will mess up the SystemUI a little. Certain apps will become too large. It also resets every time you restart the phone. Huawei needs to fix this. It's one of the worst things about EMUI.
try using wm size. it works perfectly.
apart from some apps, like camera. use tasker to reset back when using camera
Thank you so much Guys! Is there any difference at all between using minimum with in developer options, and using vm size in adb? Cheers

It really doesn't work any better than using the Minimum Width setting in developer options and like you said it even screws up the camera app.
I'm using 600 DPI and I have no problems. I wouldn't recommend going higher than 640 as you might get glitches.
Does anyone have a link on how to use that wm size setting?
