[Q] Auto Brightness in Extended Controls

I've seen references to it elsewhere on XDA and elsewhere, but cannot seem to find that setting on my Incredible.
Ideally, I would like to be able to toggle the brightness manually, but then also quickly switch it back to autobrightness when I want to.

Try add > Widget > Power control
The right one toggles through brightness

+1, although i don't believe it has control for 'auto' brightness, still have to do that manually

I just came back to say that. It just cycles through low to high

I believe cyanogen incorporates auto brightness into the power control.. unless it was some other ROM that put it on my phone

Assuming you have >v4.0 of Extended Controls, add a widget with the brightness toggle. Under the settings for brightness, use a Custom Brightness Type, and check Auto Brightness. Now you can toggle through various levels, including Auto.

[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,

Display Brightness between ROM's

Hi Guys,
Not sure if this is covered anywhere or if it's even an issue or maybe Percieved issue.
Between Flashing Cooked ROM's and Stock ROM's etc it always seems that the display while using stock ROM's doesn't seem as bright / vibrant - it always seems a bit duller at max Brightness, the Whites dont 'Pop' off the screen as much.
Is there any truth to this or is it just me? If it is the case what are the Chef's doing to make this so and can i do it to a Stock ROM?
Cheers
Paul

it can depend on 2 things
- kernel used -> some kernels disable or can disable "adaptive brightness" and modify color values
- the value set for auto-brightness in framework-res.apk. Most devs keep the standard values from google, I usually find them "too boring and dark" so i modify them.
So not your perception - you are quite correct

Ah thanks for the response. Though if i understand correctly this just affects the 'level' at which the brightness will be set at certain detected light levels on the Auto Brightness settings?
What i mean is that if i just go in and turn off Auto Brightness and slide it up to the Max - the Cooked ROM's always seem more vibrant and brighter.
Also is there anything that i'd be able to do to a Stock (rooted) ROM to get this extra Brightness?
Cheers
Paul

More details on this please?
Edit: nevermind, found it.

Mind Sharing Your findings MS? Or could someone else please help?

Here's something about content adaptive brightness:
http://forum.xda-developers.com/showthread.php?p=28126141
You can turn it off with Franco's kernel app or with Supercurio's Voodoo display app, available in his thread here on xda.

Here it is. I had no chance yet to try it, but i believe it should work.

Thanks guys - went for Francos Kernel and can now adjust the levels with the tool

Low Brightness?

First of all, yes i turned autobrightness off and turned it manually up to the max, but i think that the brightnes goes down in some apps or the brightnes is just kinda low on the note 2? i am on this rom http://forum.xda-developers.com/showthread.php?t=2259479

Brightness level on all Samsung phones is good... that ROM uses a lot of dark/black themes... so my guess is just the apps that are dark themed will appear lower in brightness.
However do check (in settings) your Screen mode.. if it is set to standard or Dynamic...check Brightness settings (in settings again, not toggles) to see if Auto is set and where the "line dot" is set... and further down check if you have "Auto adjust screen tone" checked.
But you have enough post counts to ask in that ROM thread for better answers. Good luck!

Yeah, I've also noticed low brightness on stock based 4.3 ROM.You may use some other apps to control it (never tried them).
However now I'm on miui and the brightness adapt seems much better.

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.
