When I press the power button after a call was ended the phone wakes to unlock screen

I normally end the call using the red phone icon and then press the power button. Half a second later the phone wakes by itself and is waiting for me to "swipe to unlock". If I end the call and wait for a few seconds and THEN press the power button, I have no issues and the phone stays in sleep mode. I assume it is the phone app doing some kind of refresh but it is extremely annoying.
