No use of this steps, I'm facing critical issue 'coz of voice call issues in ONE UI 3. I have done all the possibilities steps of troubleshoot but no positive out come.
Know seems I losing hope on Samsung brand as even china's MI phones don't have such issues. Hope Sammobile will soon come up with new update to fix this issues/bug. Else no other option to switch the brand.
