It has the outer screen too for when you want a one-hander. Though you’d have to go with either fold 5 or one of the other brands to get a better outer screen, fold 4 and lower were not particularly useful there. Too skinny. I pretty much only ever use the outer screen for actual phone calls. You can transition from tablet to phone while already having answered the call with no issues.

And as with all larger phones, you always have the option of going into “one-handed mode” using whatever shortcut you assigned(either diagonal swipe or triple tap home are the defaults). It’s less necessary when you just have the option of a smaller one handed screen on the outside, but still there if you’d rather that option.
