What is the switch rate to Android? I mean, I know plenty who have done it, but I have a hard time believing that it's a huge number.
I think most Android users just never have used Apple, Some due to price, some due to history (Verizon users who started android and never changed as a US example) and some due to brand or technology preference.
I mean I like Android, I liked Windows Phone better, but I like Android. And I don't like some of the traditional Apple UI choices...many of which have changed over the years. But ultimately, I just don't see the value for the iPhone price premium and I don't like the lack of choice on Performance vs. Price
So it boils down to momentum and a lot more granularity of choice for price vs. performance.
On Android, for brands in the US, between Moto, Google Pixel and Samsung (particularly Higher end Samsung phones. Don't care about their low end stuff), there is a good selection of products across the price spectrum that have solid quality and excellent price/performance options.
