That's interesting — as an Android user, I see apps with iPhones on their screenshots all the time. Sometimes they are iPhones with Android UI photoshopped into them.
You have to remember that in the Apple reality distortion field there is only Apple. I think you get thrown out of the cult if you acknowledge other things exist.
I'm well aware of that because my computer runs macOS. Interestingly, it syncs with my Google account just fine. But of course I don't enjoy the level of integration I'd have with an iPhone.
