6 Protection Tips for Flip Phone Rugged Case Users
Inspect the hinge channel area monthly for any debris that could cause binding during folding. Never force the fold when the rugged case feels stiff — debris in the hinge channel is usually the culprit. The flexible inner display of all three phones remains unprotected by the case when open — avoid placing the open phone face-down. A closed flip phone in its rugged case is its most protected state — close the phone before pocketing. Do not use the rugged case on a different flip model than it is designed for — Galaxy Z Flip 4 and Z Flip 6 cases are NOT interchangeable despite similar form factors.
