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 tried using it for a few months and just kept getting wildly inaccurate predictions. It wasn’t any faster or easier so I just continue typing normally. Plus the multi-language recognition isn’t good enough in my experience.
