The US was the first place smartphones took off and in the first couple years iPhone was the smartphone, so the initial set of adopters got iPhones because android wasn’t really a consideration. Then the network effect, people got what their friends or family had. Also, since a lot of people get their phones payed for through their cellular carrier contract, they not super price sensitive since the cost was buried in a monthly bill.
So lots of people are used to IOS, and don’t see a reason to switch. Especially now with the one major differentiator, walled garden vs open platform, is disappearing with Google locking down their platform.
