Is it possible to lower the minimum automatic brightness level?

I really like the automatic brightness feature, but IMO it doesn't get nearly dim enough in dark situations. If I uncheck the auto brightness feature, I can dim the display to an acceptable level so I know the display is capable of it. Is there a way to adjust the threshold/range of the auto brightness levels?
Thanks,
Dave

A polite bump...

I wonder if you know the answer, do you?

Try the free market app, Dimmer. It works well, especially at night. Lowers the brightness to level 10, instead of default lowest of 30.

Do you know if this app will work with the new GB roms with the new sense on the novatech screens?

[Q] Screen Brightness

hi, i'm using HTC Desire HD with leedroid rom and kernel.
i read that to save more battery, i must turn down the screen brightness to a low level. but i want to use the auto brightness function but sometimes it isnt accurate to the environment(sorry for bad english). uhm any tweaks or mods that has customized auto brightness? thanks in advance guys

I found that the best thing to do is to do it manualy by using the brightness level app on the market which has a slider on it.

I use Tasker to set the screen brightness to levels defined by me in response to ambient light levels. Takes some experimentation to get it working right, but it's worth it.

Or then you can switch to CM7 as it has all screen adjustments built in the settings i.e automatic screen dimming level adjustments, different levels etc etc.

[Q] How to lower minimum screen brightness?

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?

Yes with above linked app. I confirm it works 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

Brightness level setting

What brightness level are you guys running?
Right now I'm at ~30% (auto brightness off, of course).

im on auto since i go in and out a lot

Im on CM9, i just keep it on the normal Auto-Brightness setting.
However, I've found it to be much brighter than needed in most situations, and I can't find anyone to instruct me on the settings for the auto-brightness built into CM9 :/ anyone have any tips/info?

Settings>display>automatic backlight>edit other levels. You set a brightness setting for certain ranges of sensor values.

Colour change at min brightness.

MY issue with the stock Rom, which has been bugging me for a while is that when I reduce the brightness to the minimum, the Contrast changes, or something of the sorts, this really annoys me and I would like to disable it. Can someone help me out? I really don't want to flash a custom ROM.

I think that's normal because of AMOLED display, I also noticed it on CM14.1

This is simply the way this particular screen works, can't be fixed with software.
You can only avoid it by not reducing brightness as much. According to "Lux" the color shift starts under 4% brightness.

But why does the min brightness in mxplayer not have this issue?

Because mx player doesn't set the brightness as low as you can set it manually using the brightness slider.
Select menu - display - settings - screen - untick "brightness". Now you can set your brightness manually to even lower using the brightness slider.
Other apps seem to work similarly (for example an third party brightness widget)... Not setting it to minimum... Like they don't recognize the "real" minimum brightness - which is lower. I don't have this "issue" on my tablet. Haven't looked much into it though.
