How it fits

The case uses two shells, one for each half of the phone, joined by a guard that covers the hinge and moves as the phone opens, lying flat when it's fully open (OtterBox). Covering the hinge is one of the main reasons to choose a rugged case for a foldable.

Other cases that cover the hinge

  • dbrand Grip: a textured case with an elastic hinge cover.
  • Spigen Tough Armor Pro (MagFit): $69.99 at Spigen.
  • SUPCASE UB Grip and ESR Cyber Tough: other rugged options.
