I am unable to receive any call from the display option that appears in the whole screen. I am receiving calls from the notification. I thought that was software issue but after two updates it's same .
What's your phone’s firmware version (Settings > About phone> Build number)
Do you mean when someone call you incoming calls not showing on the phone ?
Try rebooting to safe mode and check once.
Long press power button> long press power off option> Ok> you will enter safe mode.
