A slightly bigger cover display, beefy Snapdragon 8+ Gen 1 chipset, and upgraded camera system (the same as the excellent Galaxy S22) made the Fold 4 one of the best devices of late 2022.
The Mix Fold 4, by contrast, is much lighter, weighing 226g and measuring 9.47mm, and looks and feels like a standard phone when using the cover screen, especially next to Google's clunky Fold.
