adjusting auto-brightness range

Looked on google for this and found other people asking about it but no answer so far.
If i leave the screen brightness set to auto-adjust, the phone NEVER adjust the screen brightness down to it's lowest setting, even if i am sitting in a pitch dark room. Is there some way to adjust the range of the brightness setting so that it will actually use the lowest brightness? It seems beyond stupid that in a pitch dark room the screen doesn't go down to it's lowest level.
Most of the time i find the screen to be too bright, so if i could adjust the auto-brightness over-all to be darker, that would be cool too.
failing that, is there an app that makes adjusting the brightness quicker then digging down into the settings to move the slider?
thanks

I use widgetsoid (free) from the market place to do what you speak of and 7 other things as well.

i think i already have something that does what it looks like widgetsoid does. I have a button on the screen that i can tap that switches the screen between 3 brightness settings. i was just wondering if there was one where you could tap and get a slider. Seems silly to have the actual slider itself on the screen since that would take up so much room. But a button that would open up into a slider would be nice.
I'd still prefer to be able to adjust the autobrightness settings and use that if possible.

You can set autobrightness levels with tasker. There's a thread floating around with details.

Again, Widgetsoid does this. Once it is setup, modify, settings/Brightness Modes and set it Custom (Seekbar) or use one of the other 2 settings. You can change those as well with custom. Exit. Go to toggle and you have slider with one click on one button, which option of adding 7 more.

ah ok, cool, thanks. I'm going to see if i can find the thread about tasker since i'd prefer to have auto-brightness working better. if that fails then i'll give widgetsoid a try.
thank you

Just what I was looking for Screen brightness less then 10% and Less then Curvefish's toggle to 4%. I was looking for the 1% brighness and I think i got with the Widgetsoid only compaint is no exit after setting... Thanks

How to decrease minimum backlight level?

Is there a way to decrease the minimum back-light level on a CM7 ROM?
I always prefer to keep back-light level as low as possible and not using automatic setting for it.
Recently I've tried one of the MIUI roms and noticed that the lowest back-light level on it is way dimmer that on CM7 ROMs. It allowed me to noticeably save on battery.
So is there any way to do it on CM7 based ROMs?

Tried and tested with typhoon rom. After usind this lib the cm7 autobacklight level should woork correctly..but therefore some LED Notification will behave a bit strange...you will be able to life with that. (=

not 100% as I use a CM mod (AMA), but check Settings / CM Settings / Display/ Automatic Brightness / Edit Other Levels

OK. I've tried it and saw absolutely no difference in minimum backlight level.
When I move the backlight level slider all the way down it is still on the same level
as with older libs. And it did break notification lights.
As I've mentioned before I am not using autobacklight at all. I just want to have manual backlight level go much lower.

There is a free app in the Android Market that will do just what you want. It's called Screen Filter. Using this app, you can set your backlight level very low, and even put a widget pre-set to your preferred brightness level on one of your homescreens.

that's how it looks on my device - the min brightness can be set to 1 which is very dark

This app is a fake. It does not decrease backlight level, but instead dims lcd pixels, which is not the same. Hence no power saving benefits. It would only help with OLED screens.

Did you replace lights libs to make it to work?

that's how it comes with AMA, which is based on CM7.1, so it could be part of the original CM (have no way to check as I don't use NAND builds)

Ah..I see. That is SD build.
OK. Looks like CM7 autobacklight works if I replace lights libs now (loosing LED blinking though). I guess I'll try it out and see how it turns out.
Thank you all.

One thing I've noticed that backlight level number is not very granular.
As there is no difference if I have it set to 1, 5, 10, 15 or 20. It only changes at 25

it might depend on the brightness ranges/thresholds - I've noticed in my build that if first two ranges are set as 0-100 and 100-200, the first one is ignored if upper limit is below 225, so I always get the screen brightness of the second range

I was looking for a dimmer lowest setting for the back light & tried Screen Filter BUT found it left the "black screen" well lit but everything else faded, almost like the colours were merging to gray rather than being dimmer.
Anyway, my need was for the clock display to be dim but found the Clock app's day/night mode button takes the clock display brightness right down low; lower than the manual screen brightness setting for sure... but only in the clock.
Hopefully any other noobs to Cyanogen / non-Sense ROMs may find this relevant! ;.)

[Q] backlight hack

i find myself using the tablet on lowest light settings all the time, without any trouble.
does anyone know of an app that would let me lower the backlight settings further than what honeycomb allows ?
battery use at 70% --;

I use an app called screen filter. It doesn't actually lower the blacklight but it does the trick.
Theres a couple other apps that do the same thing.

Fantastic! Tkvm ^^
This should appeease my quest for the st graal that is screen color inversion

[TIP] [Remove Blue Light from Screen by changing Kernel Settings]

Hi
So let's take a break from pursuing after Lollipop and improve what we have
Well, many of us know that a report came out suggesting that 'blue light' emitting from screens of mobile phones, TVs, PCs etc is harmful to the eye and causes sleeping problems.
And then many apps started coming out which remove/filter the blue light from phone screens, such as Bluelight Filter, Dark Screen, Twilight etc.
These apps do what they say but :-
1) They don't do it perfectly
2) You have to manually disable them each time you install something or grant superuser access to an app
3) Few of them consume fair amount of battery
4) And some people may be annoyed by the fact that it always stays on the notification bar.
So here's another the way of removing the blue light without causing any of the above mentioned problems
The way is to change the kernel settings, rather the screen color settings by using kernel tweaking apps like Faux123, Trickster Mod etc which almost every custom kernel user has.
So open your kernel tweaking app and go to' Screen' settings or 'Screen Color' settings or whatever is there and just reduce the quantity of the blue color according to your preference
I have attached a screenshot of blue light being reduced using Trickster Mod app.
Don't forget to hit thanks if this helps

Thanks for the tip,
I've seen someone using bluelight filter app with his z3 compact, i couldn't figure why. Now i know. The screen of his phone looked pinky though.

UPDATE Brightness BUG on all roms except Omni ROM

This error is very annoying, as it raises the brightness and lowers the background color. It is annoying that having the automatic brightness off will raise the brightness in some applications
I have the automatic brightness off.

Why is this posted in this forum? This slid be under questions or discussion. Correct?
I just don't want this forum to be filled with bug report posts...

Help
Hi, It is not an application BUG. It is actually a feature Had to discover this by myself.
Ok. So in my Leeco Le 2, if I go to:
Settings -> Battery -> Power Saving management -> Adaptive app brightness
And there is the function by default turned on. So you can control individually the backlight intensity for every single app on your phone, or you can turn it off completely, hence using the default brightness level of your phone.
If you find this helpfull let me know.
Best regards,
BB
