External screen duration during call question.

[JammasterKX2]

During a phone call , the external screen dims and then blanks out.

So when you go to hang up, you have to push a button to first turn the screen back on and then push a button to end the call.

So you need 2 button pushes to end a call.
Am I missing a setting to get one push to end a call?

Is there any settings for external screen duration during calls?
