The Lights.apk works fine on Kon-Tiki 2. Max warm and max cold sliders correspond to Onyx'es limits in the brightness dialog. The settings are written correctly.
I still can't figure out how to manually call the stock Brightness dialog. I tried:
Code:
am broadcast -a com.android.systemui.settings.BrightnessDialog
am broadcast -a com.android.systemui.SHOW_BRIGHTNESS_DIALOG
am broadcast -a com.onyx.action.SHOW_BRIGHTNESS_DIALOG
am broadcast -a com.onyx.action.show.brightness.dialog
but still not success. Maybe I should look in the same place where you found "am broadcast -a com.onyx.action.show.contrast.dialog"? Can you please share it?
