I am having a problem displaying the dial pad (0-9, #, and *) during a phone call. There is no icon to show the dial pad on the screen which appears when I make or answer a phone call. I checked the setting section but could not find any item which turns the dial pad on during a phone call. Does anyone know how to do this? My Jelly Pro has been updated to Android 8.1. However, I had this problem before the system update.
