There is a light icon on the screen, you can have light on or off
(Although when it is off it still shows a dim orange light as an indication that the camera is recording, a bit like the old camcorder tell tale light)
i am very much upset regarding the picture quality of Nokia 5800. As its nokia's first touch screen phone, what i was expecting that Nokia 5800 must have 5 or higher MP camera... but 3.2 MP is an old thing...my one year older nokia 6500 is having 3.2 MP features....
