This week has been a foldable fest, with not one, not two, not even three, but four new foldable phones announced in quick succession - in fact, they all debuted within 24 hours of one another. First up, Samsung gave a global launch to the Galaxy Z Flip 4 and Z Fold 4. After transformative updates to last year's models, this year is more about iteration, but there's still a lot to like here. The Flip 4 in particular has been re-designed to fix its predecessor's biggest flaws, while the Fold 4 benefits from improved proportions and a serious camera upgrade. Not to be outdone, Motorola held its delayed launch for the Razr 2022 in China. With a Snapdragon 8+ Gen 1 inside this is a match for Samsung's Flip 4 on specs, and may trump its Korean rival on camera performance too, with a 50Mp rear shooter. Throw in a larger cover display, a 144Hz internal display, and a sleek design, and Samsung may have real competition when the Razr gets a global launch later this year. Finally, Xiaomi held a Chinese launch of its own, revealing its second foldable: the Mix Fold 2. This book-style folding phone is a Z Fold 4 rival with an astonishingly thin design - just 5.4mm thick when open - along with strong specs and another Leica-branded camera.
