Is this how most people type on mobile these days, drawing lines all over a keyboard instead of tapping the individual keys? I’ve never had an iPhone so I don’t even know if they can do this natively, but I know you can switch keyboards at least, so it should still be an option if not.
I find it to be much slower and less accurate than standard typing with autocorrect. I try from time to time for fun, or when I have only one hand available, but it’s not something to be used day to day.
