Historically the foldable Achilles heel — but Motorola invested in hardware and software here, and DxOMark ranks it the best camera in any foldable.
Oppo Find X9 Pro
A Hasselblad-tuned system headlined by a 200MP telephoto and an optional 230mm extender — best-in-class zoom, portraits and night, with a strong 50MP-by-default main.
Motorola Razr Fold
