Can anyone explain what triggers the screen to come on after dialing a number?

I notice when I hit the send button, the screen turns OFF but then comes right back on again before I get it to my ear.

This is frustrating and I've been manually turning off the screen to be certain it is off before putting the phone to my ear...

Am I doing something wrong or is there a modification or setting I am missing?

Thank you.
