Totally agree with the shockproof approach, though hinge tolerances are a whole other beast. My current setup uses a sliding hinge cover, and what I found is that the mechanical friction actually scratched the outer spine of the phone over time because of trapped grit. I am pretty obsessive about specs, so I measured the added thickness and it adds nearly 4mm to the depth. When I dropped mine a few weeks ago, the case did its job absorbing the kinetic energy, but the hinge guard popped off because the clip design couldnt handle the torsional stress of the impact. Its a trade-off. You get that peace of mind for the glass, but the bulk can mess with the phones ergonomics and even how the magnets for the sleep/wake sensor align. Basically, if the fit isnt perfect to the millimeter, youre looking at potential long-term wear on the folding mechanism itself.

> My current setup uses a sliding hinge cover, and what I found is that the mechanical friction actually scratched the outer spine To add to the point above, that grit issue is a real headache with foldable hinges. I have been super satisfied with the Spigen Tough Armor Pro P Galaxy Z Fold 5 Case lately. It uses a specific hinge clearance that seems to avoid that direct spine contact Harrystync mentioned, plus it keeps the MIL-STD 810G drop rating. No complaints so far. If you are looking for a more cost-conscious option that doesnt skimp on features, the Supcase Unicorn Beetle Pro Z Fold 5 Case is probably the best value. It includes a built-in screen protector and an S Pen slot for way less than the official Samsung gear. Tbh it is a bit of a brick—adds nearly 6mm to the total folded thickness—but for the price, the heavy-duty protection works well. I also tested the Ringke Slim Z Fold 5 Case for a week. It is great if you want to keep the profile slim, basically adds almost zero bulk, but you lose that hinge coverage entirely. No complaints with the grip though. Just found this thread and wanted to chime in since I spent way too much time measuring case tolerances last month...
