Three Generations: How the Galaxy Z Fold Line Evolved
The Galaxy Z Fold 3 (2021) was the first Galaxy Z Fold with IPX8 water resistance, an under-display camera on the inner Flex Window, an S Pen slot, and a 7.6-inch inner display — representing the first truly production-ready Samsung book-style foldable. The Galaxy Z Fold 4 (2022) refined the Fold 3 formula with a wider outer Cover Screen (6.2 inches from 6.2 inches), improved camera system (50MP wide replacing 12MP), a built-in S Pen slot, and a thinner hinge profile. The Galaxy Z Fold 5 (2023) introduced Samsung's new Flex Hinge that allowed the first gapless fold — no visible gap between the displays when closed — along with Snapdragon 8 Gen 2, a 7.6-inch inner display, and IPX8 water resistance.
Hinge Architecture: Why Each Generation Needs a Different Case
The most critical engineering difference between the three Gorilla Cases Galaxy Z Fold models is the hinge accommodation. The Z Fold 3 hinge is the largest of the three — the Gorilla Cases Galaxy Z Fold 3 case has the widest hinge cutout. The Z Fold 4 hinge is thinner than the Z Fold 3 — the Gorilla Cases Galaxy Z Fold 4 case uses a narrower hinge accommodation profile. The Z Fold 5 introduces the gapless Flex Hinge that folds completely flat — the Gorilla Cases Galaxy Z Fold 5 case accommodates the slimmer flat-fold hinge profile while maintaining the MIL-STD-810G protection standard. These three hinge dimensions are not interchangeable — use only the case designed for your specific Fold generation.
S Pen Accommodation Across Three Generations
The Galaxy Z Fold 3 was the first Z Fold to support the S Pen Fold Edition, but the S Pen silo was not built into the phone — you needed the S Pen case accessory to carry the stylus with the device. The Galaxy Z Fold 4 maintained the same approach. The Galaxy Z Fold 5 introduced a built-in S Pen slot in the phone body itself. The Gorilla Cases Galaxy Z Fold 5 case includes a dedicated S Pen slot cutout for ejection and reinsertion without case removal. The Gorilla Cases Z Fold 3 and Z Fold 4 cases do not need S Pen silo cutouts as those models store the S Pen externally.
Camera Protection: Evolving Camera Modules Across Generations
The Galaxy Z Fold 3 has a triple-camera system (12MP wide, 12MP ultra-wide, 12MP telephoto) plus an under-display 4MP selfie camera on the inner Flex Window. The Gorilla Cases Galaxy Z Fold 3 case ring covers the full rear triple-camera footprint. The Galaxy Z Fold 4 upgraded to a 50MP wide sensor (with a larger module footprint) plus 12MP ultra-wide and 10MP periscope telephoto. The Gorilla Cases Galaxy Z Fold 4 case ring accommodates the larger 50MP module. The Galaxy Z Fold 5 uses the same camera system as the Z Fold 4. The Gorilla Cases Galaxy Z Fold 5 case ring is identical to the Z Fold 4 ring geometry.
Cover Screen Dimensions Across Generations
The Galaxy Z Fold 3 Cover Screen is 6.2 inches at HD+ resolution. The Galaxy Z Fold 4 Cover Screen is also 6.2 inches but slightly wider in aspect ratio. The Galaxy Z Fold 5 Cover Screen is 6.2 inches. All three Gorilla Cases models include raised bezel protection for their respective Cover Screens, following the slightly different aspect ratios of each generation.
Who Should Buy Each Generation's Case
Buy the Gorilla Cases Galaxy Z Fold 3 case if you own the Z Fold 3 and want the first-generation Z Fold hinge protection with IPX8 water resistance defense.
