Samsung j3 lock screen during calling

[AC Question]

I can't find in manuals for samsung j3 how to lock screen during calling, I just wondering if someone knows how to do that? During calls with someone I often touch with my face screen and press many buttons. Thanks for the effort to answer me.

Welcome to Android Central! Open the Phone app, tap Menu>Call Settings, and see if there's an option for "Turn off screen during calls."
