6 Protection Tips for Galaxy S23 Ultra Waterproof Case Users
Before first water submersion, verify the S Pen silo seal is fully seated — press the S Pen fully in and confirm the seal closes around the top of the silo port. Rinse the Galaxy S23 Ultra waterproof case with fresh water after ocean submersion — saltwater accelerates silicone seal degradation if left to dry.

Do not charge the Galaxy S23 Ultra while the waterproof case is wet — dry both the case and the USB-C port area before charging even with the seal in place. IP68 certification applies to still water — avoid high-pressure water jets or waterfall flow environments, which can exceed IP68 limits.
