Protection Tips from Gorilla Gearheads
The Galaxy Z Flip 4 rugged case's hinge-flex zone is calibrated to the Z Flip 4's specific clamshell hinge arc. Do not attempt to force the Z Flip 4 closed with extra force if you feel resistance through the rugged case. Resistance indicates either debris in the hinge-flex zone or a case seating issue, both of which should be addressed before forcing the close.
Clean the 1.9-inch cover display bezel area with a soft brush monthly. Pocket lint accumulates in the small gap between the cover display glass and the case bezel, and while it does not damage the display, it reduces the aesthetic appearance over time and should be removed regularly.
The Z Flip 4 rugged case's non-slip texture is designed for dry-hand grip. In wet conditions, use two hands when handling the Z Flip 4 to maximize stability beyond what the grip texture alone provides.
After several years of use, the Z Flip 4 battery may show reduced capacity. If you notice the phone running hotter than usual during charging, remove the case for one hour per day during heavy charging sessions to allow heat dissipation from the USB-C port area.
