My iPhone SE (refreshed version) hits all of this, except the 2 USB connections -- which is a very specific request, but w/e, I don't judge. In my mind still is one of the top 5 smartphones available, even if it hasn't refreshed in a few years.
I actually stopped optimizing my app for your screen size. I have no idea if it even works. Surprised there are people out there still using these!
Isn’t there some sort of analytics you could add to your app to learn the screen size of your users?
