@dbc3 I got so fed up with swypos (good term!) I adopted a completely new keyboard layout - MessagEase - it's designed for touchscreen, is based on gestures on a 4x4 grid of larger buttons, and allows reasonably fluent typing and text editing on even a small and underpowered phone… which is what I had ten years ago!

I don't know if anyone else uses "swypo" but I came up with it independently a few years ago.
