I am not the person you asked, but I might be able to give some input. My “credentials”: I have owned many many phones because of my job, and currently still use 3 smartphones on a daily basis: two Android phones and one iPhone. Cost is not at play in my case, so there is also no sunk cost.

I wrote up something, but I feel that it is both below the standards of HN, and not something I would want to publicly attach my personal name to. I’d be happy to send it to you if you’d like.
