What I want is a physical smartphone keyboard with nine keys. The one with three letters per key. I've never been faster and more accurate at typing on my phone than when these were a thing. I have pretty small hands, but even for me those full-size mini-keyboards are too imprecise to make them much better than a touch keyboard.
I've used this since 2014 when I made the first version, and I have yet to meet anyone typing faster with the stock iPhone qwerty keyboard.
