I'd like to lower brightness level of display below its factory minimum.
I tried to edit values in framework-res.apk/res/values/arrays.xml
<integer-array name="config_autoBrightnessLcdBacklightValues"> etc...
But my decompiled "framework-res.apk" does not have the directory "/res/values" at all!

I wanna add the ability to change minimum brightness to the value of "1" for example.
Do not offer apps like "Screen Filter" because I wanna save the battery.
I have read the topic " [HOW TO][MOD] Lower Brightness levels [04/05/12]"
But it's for Samsung devices.
I'm afraid it will not work too...
Answer please. How to change the system brightness below its factory minimum?

I have tablet PC Vido Yuandao Mini S, Android 4.2.2 Jelly Bean (rooted). SoC is RK3188.
Please help.
And thanks in advance.

you have to decompile your apk with apktool so maybe you can find that files. i also edit framework but it seems nothing happen ... i dont know why

All of you just use lux app. I am using it it's great you can lower brightness even to 0(means your screen will become black) with this app

Thank you, but I wanna save the battery life.
LUX app DO NOT lower the system brightness. This program just puts a dark semitransparent layer on the top of other apps.
And thus creates visibility of brightness reduction. I underline - only VISIBILITY.
"Screen Filter" and other similar apps do the same trick.
BUT!
I want to reduce the value of SYSTEM brightness.
I wanna dig the firmware but I have no so much knowledge.
This task is not very easy, alas...
Help me if you can.

Damn man, we're looking for exactly the same thing! Those apps which only put dark layers really don't help at alland I would rather keep the original brightness instead of the distorted visual experience. I've been struggling on my android 4.3 system for a long time and I still didn't find the correct way to solve this problem. The app I use to adjust the brightness only worked on the 4.1 system long time ago and it wouldn't go below 15% since then. I tried editing many system files but I still didn't find the right way...
