Suddenly I see many iPhone X around. 2 in 10 ratio I would say (including Android). It’s definitely a lot but I live in London if that makes any difference so there might be a natural bias towards iPhones.
I think the iPhone has such a strong following not just because it's a well-made iPhone and iOS, but because Apples marketing is so dominant in the media today. And consumers tend to focus on what they see, and the iPhone is one of those phones that is unavoidable.
