[Q] Difference: Proximity and Ambient light Sensor - HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting

Hi,
What ist the difference between the Proximity Sensor and the Ambient Light Sensor?
I know, the output of the Ambient Light Sensor depends on the ambient light
but what is the proximity Sensor? How does it work on the HD2? What are the output values etc?
And: what is the main use for it?

The proximity sensor uses IR light to detect when an object is close to it. In the case of a mobile phone it uses this information so the screen can be turned off when the proximity sensor notices your head (or more accurately, your ear) which may inadvertently press on the screen when making a call. As far as the output values? I have no idea.

[Q] Change proximity sensor settings

Is it possible to change the sensitivity of the proximity sensor on the Vibrant? I feel like it is not sensitive enough.

[Q] Light sensor on the X10?

Hello,
If I look in the sensors section of "Android System Info", it doesn't list a light sensor (I believe that the light sensor is used to dim the screen when it's dark). The thing is, I've seen the screen dim by itself before. If I put my hand on top of the phone (where the proximity sensor is located... I think...), the screen dims. If I remove my hand, the screen gets brighter.
Does the X10 have a light sensor or not? Is it possible that the light sensor is "hardwired" to the screen without "passing" through the OS to dim the screen?
The light sensor on my X10 is to the left of the earpiece. To the right are the proximity sensor and further right is the notification led.

Since you can disable it in the settings, i don't think it's hardwired.

Good point, I don't understand why android system info cannot see it though. Same goes for the service menu, it seems it's the only sensor in there that cannot be tested.

[Q] light sensor and light sensor lock question

Main question: is the light sensor always on even if I turn off the "automatic brightness" in Display settings?
If the answer is no, I might have to reconsider the usage about light sensor lock.
(I thought the sensor is working at all time, so add the light sensor lock would not draing the battery faster)

[Q] Change the sensitivity on the proximity sensor

How can I change the sensitivity on the proximity sensor? The default range gives the sensor a slow response and I want to change that.
