Have a BIG PROBLEM, because some "Expert" when I bring a phone for exchanged say is 100℅ fine and you go to travel and wanna proof your "vaccine status and negative test for coronavirus etc.", only I give one because you're don't have -1000, It's first in my history negative review, I'm only 43 years old, I hope the person who calls him, Engineer will have a similar problem or even worst in his life.
