Root Dim Screen Past Minimum?

Rewt

Newbie
Hey,
I was wondering if there's any way to dim the phone's screen brightness beyond the enforced minimum value? In many dark situations even the lowest setting can still be way too bright to look at comfortably in addition to wasting battery. All of the other phones I have owned have gotten much darker than this one.

I have searched extensively on this, and the best solution I found is the app Screen Filter. However, all it really does is darkens the colors (puts a partially transparent black image over the screen), it doesn't actually dim the backlight. While this helps a little bit as far as reading (turns the bright whites into bright greys), it still is not nearly as good as it could be if the actual backlight was darker. Also, it doesn't do anything for battery life (as this is LCD not amoled).

I am both root and S-OFF and wanted to know if there's anything that can do this.

Thanks
 
I hope someone has a solution to this too. The only thing is Leedroid that currently know of that does it. But I'm stock, any other way?

Leeroid doesn't do this AFAIK. The only setting I see is to change auto-brightness sensitivity. Like, to make the auto brightness more dim under the same lightning conditions. Under no light, auto-brightness sets the backlight to the system minimum regardless

Velis Auto Brightness. Been using it for a couple weeks now.
Just looked at that, and considering it doesn't require root, I see no way possible it could do this.

To clarify, I'm not trying to change the auto-brightness. I just want some way to manually set the backlight/brightness below what it normally allows

Unlike Velis, this does EXACTLY what I want. Thanks!

No problem. Velis works well for me, though it gets hung up at times and doesn't auto adjust. I have it set to the amoled base setting, so it's brightness in dark rooms is as bearable as a Nexus or iPhone.
 
I should have started this thread long ago, as it has what I missed most from my Triumph running CM7.

I purchased the suggested Lux app. It does almost all of the job.

Oddly the free app has a silkscreen button option that the payed app does not. It really doesn't work on the free app, so it is not really missed.

I have been turning down my silkscreen buttons by hand. The dimmest setting I could find was to run the following as root :

Code:
echo 2 > /sys/devices/platform/leds-pm8058/leds/button-backlight/currents

My wish list would be a single lux threshold that would turn the silkscreen buttons on dimly below, and turn them off above. If I have light I can see the paint. Perhaps I should send a request to the developer?

Actually I take this back. I tested it under full light, and it appeared to lower the backlight with sub-zero. However, after using it last night, I noticed it is actually just the same as screen filter and just darkens the colors, not the backlight.

I use root dim for when I need to set it lower.
And I just tried that, and it didn't improve anything. It let me lower it to 1/255 which I can already do with tasker and is too bright.

By silkscreen, do you mean the home/menu/back/search buttons? For those (at least for me) aren't an issue as I can adjust them through Kernel Tuner (on midnight ROM), and I just turned them completely off.

So, anyone got any other solutions? I'm starting to think this is a hardware limitation or at least something in the kernel. I can turn the brightness all the way down to 1/255 and it's still not dim enough. And, if I turn it to 0/255, the screen goes completely black for a second, and then turns itself back to 1/255.
 
Its impossible. It's a hardware limitation, and something I've learned from computers monitors. Your best bet are the apps you have.
