Same here. I adopted Dvorak as a youth, so when I got my first smartphone I put the keyboard in Dvorak.

That only lasted a few days for two reasons:

1) What you said about the mistakes. It is so much easier to fat finger in a way that makes autocorrect clueless.

2) The muscle memory doesn't translate at all anyway. Obvious in retrospect, but typing with your thumbs is a completely unrelated skill to touch typing. Turns out both live separately and equally in my brain.

for phones, have a look at thumbkey https://github.com/dessalines/thumb-key (messagease like)

I also recommend dactly (see also https://ryanis.cool/cosmos/ for a more generic keyboard generation)

Huh, I do use Dvorak on my phone. I have a weird phone typing style with my left thumb and my right index finger.

My biggest issue is how often I hit '.' instead of 'p' for some reason.
