Weird. I've never even heard of Vivo. All the wealthy Chinese people I know have an iPhone. I genuinely believe that they would be embarrassed to have anything other than an iPhone. They shake their head when I tell them how great an Android is. Even on TV, in the dramas, the rich characters always use iPhone and Macs. I've never seen anyone use a Lenovo or Vivo phone on chinese TV drama.

To be fair, Samsung is also considered kind of high end. They won't let you into starbucks unless you have an iPhone or Samsung something (just joking, sort of).

I've never seen a vivo in Beijing before. iPhones...plenty, but vivo?

Also, there phones look mighty affordable (none above 3K RMB):

Compare to iphones (all new models > 4K RMB):
