Re: how do I keep screen on while in call
 

try this <taken from xda-developers>

Lightsensor Switching the Screen off- realised by yelitterulez, confirmed by pietrucci and tested by myself. When making a call the screen stays on if you leave the phone lying flat on a table. If you wait 10 seconds into the call, you can pick it up to your ear and the screen stays on.

BUT if you make a call with the phone slightly tilted/ slanted (you get the idea), the screen turns off as soon as the call gets connected!
The moment you hold the phone to your head the blacklight turns off. In fact: the moment you hide the screen with anything it turns off! (try your hand...).
This might be the reason why everybody's complaining about the screen turning off during a call: you hold the phone to your head! When you turn the screen back on manually, it stays on no matter if you hold your hand or head...

Weird... my screen doesn't turn off when I make a call. It stays on and I have to turn it off manually. I would like it to turn off actually.

Re: how do I keep screen on while in call
 

I agree. I almost always wait until after it vibrates (connects) and then hit the power button anyway. I hate cheek hangups... but mine does not auto-shut off.

I thought maybe mine was already defaulted differently, but HKCU/Control Panel/Phone/Sleep was set to 1 like everyone else's. So as I understand it, it should be doing the auto-shut off?

Mine shuts off during a call, but not right away. I checked this when I first got the phone, and I know it's not doing anything based on the light sensor. If I'm checking voicemail or something else fairly quick it will stay on. Only during a conversation lasting a few minutes will I find it off. Doesn't really bother me either way, just assumed it was the phone's power settings turning it off.

Anyone know how I can enable my light sensor so it autoshuts off when it's up to my ear?

I would also love to do this, I drive a lot at night and the backlight against my face can be distracting.
