Why does my screen go dark when I hit the call button (Galaxy S5)?

why does my screen go dark when i hit the call buton? Galaxy S5

I didn't change any setting but for some reason the screen goes dark when I hit the call button and I don't know if it connects or hangs up or anything. Hitting the back button doesn't help. Thanks for your help!

Welcome to Android Central! When the call ends, does the screen come back on again? It may be a problem with the proximity sensor. I assume the screen is going dark even when it isn't up against your ear, right? Make sure there isn't anything blocking the proximity sensor, like a dirty screen protector or an ill-fitting case.

In most cases i've encountered, its phone / screen guards / protectors
