I am using LWUIT to build an application. In LWUIT, you can backlight your cell phone with the following command:
Display.getInstance().flashbacklight();
The backlight flash frequency is quite low.
How do I make the backlight faster?
You must call Display.getInstance.flashBacklight(int duration); so many times. Try to insert this method after a while (or in a loop Thread ) and use a small value for the duration.
Display.getInstance.flashBacklight(int duration);
