The Google Pixel Fold, folded and unfolded.
The Google Pixel Fold stands out among foldable phones due to the usefulness of its exterior display.

Since their release starting in 2019, foldable smartphones have been a niche, expensive intrigue. Rather than foldable phones, they've acted more like foldable tablets, and the traditional phone experience has felt like an afterthought with oddly shaped exterior displays tacked on to the front.
