Having been a teenager once myself, I can attest that there's nothing in this world that'd more successfully ostricize a kid socially, than grouping them with other isolated kids.
I think it depends how big the group is. If the group is 3 or 4 kids, then yes, that will be a problem. If the group is larger where they can choose who their friends are and not be constantly surrounded by others with phones, then it might work.
