The short answer is no — you cannot use a Samsung Galaxy Z Fold 7 case on a Galaxy Z Fold 8 Ultra. Even though both foldables share almost identical dimensions (158.4 × 72.8 × 8.9 mm when folded and 158.4 × 143.2 × 4.1 mm vs 4.2 mm when unfolded), small design changes mean cases won’t fit.

The camera housing on the 8 Ultra is slightly larger and positioned differently, and the hinge mechanism has been altered to reduce creasing. These two subtle discrepancies prevent a 7‑case from sliding onto the 8‑Ultra’s frame and locking in place.

If you’ve taken advantage of the preorder deals for the 8 Ultra, make sure to shop for device‑specific cases to protect your new foldable. Samsung high‑quality cases also offer improved grip and a slimmer profile, making them easier to slip onto the foldable.

Derrek Lee of Android Central highlighted these differences in a detailed comparison wagen while enthusiast Namerah praised the Ultra’s slim, tall design but cautioned buyers to avoid the older 7‑case. With its near‑zero crease and robust IP rating, the 8 Ultra is truly the successor for those who value a clean display.
