This is another ongoing problem. 10 seconds into an outgoing or incoming call the screen dies which makes it really annoying as I cannot see the keypad or any other options to mute or end the call.

My Google searches have also been fruitless.

-Setting, display, screen timeout. This was one of the first setting I changed when I got the phone and it has worked fine... except during phone calls! It still dies 10 seconds in.

-"Smart Stay" is an app which keeps being recommended. I found no such app installed or offered from Samsung or the Google Play store.

-Settings, Advanced Features, Motions and Gestures, "Keep Phone On While Viewing" No such option or similar option exists.

-Go to the Phone icon, settings, "Turn off screen during calls" no such option or similar option exists.

Please help!
