Me, I'm just an owner of both phones who can easily tell you that you are wrong. He was not lucky, you should be the unlucky guy that got a defective, laggy and slow S7 or S7 edge, if you say so, because the rest of the millions of S7/S7 edge owners out there, including myself and 4 other members of my 7 family plan phones, have almost perfect, smooth and lag free S7 and S7 edge phones.
You don't like Samsung, that's good, you can keep on bashing then on every single post that mentions the latest Samsung flagships, but don't get upset when people like me just call you out with simple facts, that's how forums work.
As for me, this is the last time I waste my time and energy on this topic with you, I don't need to keep talking about something that just fan boys can't accept, Samsung made a heck of a great phone this time around, you can like it or not, that's the greatness of Android and it's choices.
So, see you around...
