I wonder if it is possible to control backlight from user application in series 60. The only mentions I found were key code and scan code for backlight key, but I was not able to make it work using SimulateKeyEvent or Simulate raw event. The phone is 7650 model and there is no special key for turning backlight on. When backlight is off you can press any key to turn it on. But simulating key pressed doesn't help also.
On the other hand there is some API in Java SDK in DeviceControl class. Does it really work for backlight control on 7650?
Is there any possibility to call screen driver for backlight changing?
All answers are highly appreciated. Thank you.
