I face this problem just I use a headphone with wire or wireless. I answer a call and end it with headphones, screen doesn't close automatically and due to my phone in my pocket, something happen unwantedly.

That's how calls are intended to work, does your phone has a pin lock?

When I answer a calling on the phone, I face this problem! No third part application I use for calling likr whatssapp etc. I don't use a pin lock! Always end a calling via headphone, my screen stay open. I think proximity sensor does not work when I end any calling via headphone. Normally ofcourse proximity sensor works very well! I just face this problem when I use a headphone. I don't need to out of the phone in my pocket when I use headphone. But, when I end calling via headphone, due to my screen opens my phone call anybody itself.
