Iphone 6s and iphone 6 screen go black when make phone calls question

[perlsyntax]

Do the iPhone still make the screen go black when you make phone calls and when you try to type a number go black?

... the proximity sensor turns the screen off during a call so you don't press anything with your face, that's the only time it "goes black"
