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.
As with a few others I only really use it when I’m using the phone one handed. If I’m eating and want to reply. Otherwise two thumbs tapping away is quicker for me.
