With multi-line enabled (at least on the Galaxy S8+), anytime you dial a contact, a dialog pops up asking which number to dial from even if there is only one line registered. The software should be smart enough to skip this dialog when there is only one phone number registered on DIGITS on the device. This just ads an extra useless pop-up. Please fix this in the next software update.
I already posted a thread on this during beta. Yes it still does it even when you make it default.
