Samsung's Galaxy Ultra lineup produces a new flagship every year, and while each generation looks similar, the S Pen slot position, camera system layout, and internal dimensions shift enough between generations to make cases non-cross-compatible. This three-generation Galaxy Ultra slim case comparison from Gorilla Cases covers the Galaxy S26 Ultra, S25 Ultra, and S24 Ultra.
S Pen Slot: The Key Differentiator
Every Galaxy Ultra from S24 onward includes Samsung's built-in S Pen stylus, housed in a slot at the bottom-right of the device. The S Pen slot requires a precise pass-through opening in the case—and this opening differs by generation. The Galaxy S26 Ultra uses a 2.1mm S Pen slot at a specific coordinate position on the device frame. The Gorilla Cases S26 Ultra slim case uses a 2.1mm precision pass-through at the correct S26 Ultra coordinate. The Galaxy S25 Ultra uses a 2.0mm S Pen slot at a slightly different position. The Gorilla Cases S25 Ultra slim case uses a 2.0mm precision pass-through at the correct S25 Ultra coordinate. The Galaxy S24 Ultra uses a 2.0mm S Pen slot at the S24-generation position. The Gorilla Cases S24 Ultra slim case uses a 2.0mm pass-through at the correct S24 Ultra coordinate. These positions are different enough that using a prior-generation case blocks S Pen removal. Never use an S24 Ultra case on an S26 Ultra or vice versa.
Camera System Evolution Across Three Generations
The Galaxy S24 Ultra used a rectangular camera island with four lenses. The S25 Ultra updated the arrangement with a modified quad-camera layout. The S26 Ultra features Samsung's 2026 quad-camera system with an enhanced 200MP main sensor. Each generation's camera layout requires a generation-specific case cutout—Gorilla Cases engineers each cutout to within 0.3mm tolerance for each generation's exact camera geometry.
Slim Case Construction
All three Gorilla Cases Samsung Ultra slim options use the same 1.2mm ultra-thin TPU shell with reinforced corner pockets. The slim TPU construction adds minimal bulk while providing 3-foot drop protection. The in-screen fingerprint sensor works through the slim TPU material. Samsung DeX and wireless charging remain fully functional through all three slim cases.

Why Generation Specificity Matters
Some users try to use a prior-generation case when upgrading. With Galaxy Ultra, this is particularly problematic due to S Pen slot position shift. An S24 Ultra case placed on an S26 Ultra will block S Pen removal—the core productivity feature of the Ultra lineup. Always use a generation-specific Gorilla Cases slim option when upgrading between Galaxy Ultra generations.
