Brightness problem

[Der Mond]

In my app I have to turn off the screen but keeping active the touch screen.
I use this code:

Dim Phone_Brightness as Phone
Phone_Brightness.SetScreenBrightness (1/255)

I tried it on an X8(OS 2.3.3) and an LG P500(OS 2.3.3) and it works perfectly (all black screen), but on Galaxy S2 (OS 4.0.3) the screen doesn't become completely black.

Is there a soluction to solve this problem?


Thanks a lot
Vincenzo

I guess that this is the minimum brightness that this phone accepts.
