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.
This is very common if you switch languages often. Half the time I’m typing something in spanish and want an english word it jumps the gun and outputs a word I’ve never ever used, and viceversa. That said, I still prefer swipe.
