I've only got my family and friends to reference, but it breaks about 70/30 with the MAGA conservatives on Android/iPhone and 80/20 for the liberals/leftists preferring iPhones.

And of my family at least, I suspect a big part of that is the conservatives are not the tech savvy ones who go into a store, knowing what kind of device they want; they just go into their cell phone provider and get whatever is least expensive for a smartphone
