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.
GBoard is great for swipe typing and a must have on all my phones. I also like the one-handed mode which lets you shrink and move the keyboard for easier reaching. I usually have it small, slightly higher up, and on the right side so I can type without having to stretch my thumb and can keep a firm grip on my popsocket. Recently sent an entire text message without looking at my phone while walking down the street.
