I remain an irreductible fan of the one-hand theory, and therefore stick with an iPhone 13 mini. I might be late at the folding-phone revolution. Alas it seems we won't see any such phone that fits in a pant's pocket and that can be operated single-handedly. I am afraid that the 13 mini is the last of its kind. Yet many reports of people dropping their gigantic phones. Maybe that's a business model after all.
Samsung is testing the water with their new passport-size fold phone. Looklike enough people demanded for smaller size phone. Granted it is still considerably bigger than ip13mini, but it's step in right diretion
And, as I understand it, it tends to give more usable screen space for viewing videos but is actually more difficult to use one-handed than the newer tall/narrow candybar format.
The normal Android one hand mode doesn't really help at all on the squatter passport format as it works by moving the content down, not across.
