Ok sorry. when i am in a bright room my screen is bright. When i am in a dark room my screen is dark.

That's right. when you are in a darker room, it does not need to be set at full brightness. The brighter the ambient light, the brighter the screen. It would be extremely difficult to see the screen in a brightly lit room if the auto sensor dimmed the screen.

The iphone uses both. The light sensor turns off the screen and the capacitance screen helps to minimize false presses by your face. snovvman was wrong in his explaination.

I've been playing around with the light sensor and I now understand why people complained about the feature that turned off the screen in a call and why it has been disabled. The problem is that the light sensor is not particularly sensitive in low light.

Using the "testHTCSensorDemoAP.exe" tool you can see how the light sensor reacts. It is good for brightening the screen in bright situations, but it drops to 0 (no light detected) in dim (but not dark) situations. So in this case, it would turn off the screen even if you didn't want it too (Ex: using the mute or speaker buttons or doing anything like taking notes or looking up other numbers) while on a call.
