I thought that phones with proximity sensors should automatically put the screen in sleep mode when on a call so that your cheek doesn't accidentally press buttons during a call. As much as I like this phone, I'm surprised that this phone doesn't do that.
It does do that. Mine does that, anyway.
You might have a defective one? Try making a call to an information line or something (or a number where you know nobody will pick up right away) and then hold your finger over the sensor to see if it goes dim. It should go black almost immediately if it is working properly with stock settings in place.
