I tried to change the SCREEN BRIGHTNESS MODE to Automatic, I Use the following code, It Changes the Check Box in Notification Area of the Mobile, But doesn't applied
Code:
       
toggleButton1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
if(b)
 {
        autobr=1;
        s1.setEnabled(false);
        Settings.System.putInt(getContentResolver(), Settings.System.SCREEN_BRIGHTNESS_MODE,Settings.System.SCREEN_BRIGHTNESS_MODE_AUTOMATIC);
 }
 else
 {
        autobr = 0;
        s1.setEnabled(true);
        Settings.System.putInt(getContentResolver(), Settings.System.SCREEN_BRIGHTNESS_MODE,Settings.System.SCREEN_BRIGHTNESS_MODE_MANUAL);
 }

       WindowManager.LayoutParams lp2=getWindow().getAttributes();
       lp2.screenBrightness = WindowManager.LayoutParams.BRIGHTNESS_OVERRIDE_NONE;
       getWindow().setAttributes(lp2);
}
});

1. Does your phone surely support automatic brightness?
2. Did you declare relevant permissions to change the display brightness state?

I Checked in Samsung Galaxy Grand, It has a option to enable/ disable the Auto Brightness setting
When first I install this app, at first it shows effect, from next time it doesn't work...

So are you sure that it doesnt work? Try putting manual brightness to minimum and then switch via your app to automatic brightness. Then put the phone under a bright lamp and see if there still is no effect visible. Because i cant really believe that it works once but then not. Maybe you just dont notice it because it already has adapted the right brightness
