Display brightness is controlled by liblights.so (in android_rootfs/system/lib/hw/)
AFAIK, the automatic-brightness display "feature" is a vendor feature and not part of standard Android. (i maybe wrong. havent looked into ICS sources regarding display backlight brightness). Usually the ambient-light sensor OR the LCD content itself is used to scale the backlight brightness levels automatically to enhance the effective dynamic contrast of the display. Just implementing the ambient light sensor will NOT create the auto-brightness options in the setting menu. regards ChinmayVS On Wed, Feb 1, 2012 at 8:44 AM, Alvin Wong <[email protected]> wrote: > Hi, > > I think you have to add libsensors to your build.
