I use smartphones (including typing) by pecking at the screen with my ring finger, I find pecking with my index finger uncomfortable and my thumb too short to reach everywhere. I'm probably a useless sample, though. Because the "proper" way to thumb a smartphone is to hold it in both hands and use both thumbs to smother the phone. I find this impossible because I have unusually sweaty hands.
