I'm using Samsung Galaxy S5 (SM-G900H). Whenever any call is received after that the scree does not shuts off automatically. I've checked the settings, the backlit time is set to 30 secs as well as Smart Stay feature is turned off. It is currently running on Android 6.0.1
We apologize the inconvenience caused. We would suggest you to check your Samsung device in safe mode and through reset option. Steps avaiable on Samsung Members Application> FAQ>Setting/System.
