How do I stop the power button from hanging up my phone calls?

[AC Question]

I just got the Droid Turbo and when I am on a call the screen will dim. I press the power button to reactivate the screen but it hangs up the call. There does not appear to be another way to reactivate the screen while I am on a call. Tapping it doesn't work. Does anyone know how I can stop the power button from hanging up my calls?

Check under settings -> phone and see if the option is there. I have an option like that on my Galaxy.
