You make a good point, but to counter, can modern touchscreen phones be used without looking at them? Volume buttons and power off / on can be used without looking, but you can also use those without unlocking your phone.

I don't speak for others, but yes I can navigate from locked phone to messages and type a full message to my wife without looking at the screen, thanks to qwerty knowledge and GBoard's "swipe" typing.

How do you deal with your phone being in different states before unlocking?

For example, if you have an app open in a folder, you'll have to press the home button 3 times: once to exit the app, another to exit the folder, and a third to go home (unless the messages app is on the dock, then you can press twice to reach it).

I'd be worried about messaging the wrong person, and I also have fat fingers so that's no help :(
