Officially, no word on that, but based on testing and what a lot of creators and marketers have seen, iOS devices tend to get better initial reach, especially on IG Reels and TikTok. Now the metrics and the details of these observations are of debatable significance. Assumptions range from better camera quality, encoding, or just the algo giving preference to iPhone users (since they’re often in higher value markets).
That said, if you’re using a high-quality Android with clean USA IP and good content, you can still go viral. Just make sure your video quality is solid, audio syncs right, and you're not using sketchy automation apps that leave fingerprints. Just how much more effective iOS is entirely speculative as well.
