Xiaomi Mix Fold 4 review: Leica book-fold with a 7.98" inner display — Xiaomi's 2024 Fold flagship.
Xiaomi's Leica fold-flagship.
Mix Fold 4 brings Leica Summilux glass and a true 5× periscope to a book-fold — the only Chinese fold of 2024 with that telephoto reach. Against Galaxy Z Fold 6 (longer support, narrower aspect) and Honor Magic V3 (thinner), it wins on camera.
