In ICS you need to set autobrightness in your device overlay and provide a table which maps ALS values to backlight intensity. See the following example in AOSP for 'tuna' device: https://android.googlesource.com/device/samsung/tuna/+/android-4.0.1_r1/overlay/frameworks/base/core/res/res/values/config.xml I am not personally familiar with corresponding Gingerbread code but simething similar may be needed in your case. -Vishveshwar -- -- unsubscribe: [email protected] website: http://groups.google.com/group/android-porting --- You received this message because you are subscribed to the Google Groups "android-porting" group.
