This makes more sense and closer to the figure i kinda pulled out of thin air just based on the size of the playerbase, the 500M> figure was way too much considering that Fortnite only generates about 1.8b a year and it's revenue is going down.

Android is likely a much much smaller to the point of being a rounding error for Epic right now, there aren't many devices that can play the game right and in the markets that they actually get revenue from they aren't that popular.

I don't think Epic has any other games on the App Store tbh, and they probably didn't include licensing revenue.
