6 billion smartphone subscriptions worldwide (according to https://www.statista.com/statistics/330695/number-of-smartph...), Android is about 70% (https://gs.statcounter.com/os-market-share/mobile/worldwide), and has been predominantly USB C for the past 5 years or so (eg Samsung S7, released in 2016, was their first phone with USB-C afaics). I don't think it's that far fetched.
