If you want the best Galaxy Note 20 Ultra waterproof case 2026, Gorilla Cases offers the only solution that takes the Note 20 Ultra's full functionality — including S Pen access — seriously in a waterproof design.
The Galaxy Note 20 Ultra is one of the most capable Android devices ever built, combining a 6.9-inch Dynamic AMOLED display, 108MP camera, 5G connectivity, and the integrated S Pen stylus that defines the Note series. In 2026, Note 20 Ultra users who rely on this device for both productivity and outdoor adventures need a waterproof case that protects everything about the phone — including the S Pen slot. The Gorilla Cases Galaxy Note 20 Ultra waterproof case is engineered to deliver this comprehensive IP68 protection without sacrificing S Pen accessibility.
Why the Galaxy Note 20 Ultra Waterproof Case Matters in 2026
The Galaxy Note 20 Ultra has its own IP68 water resistance rating from Samsung, but that factory rating does not protect against port wear, case seam degradation, or the aftermath of device repairs that can compromise original seals. An aftermarket IP68 waterproof case provides a fresh, independent water seal over the device, adding a redundant protection layer that is particularly important for Note 20 Ultra users who regularly expose their device to water.
The S Pen complicates waterproof case design for the Galaxy Note 20 Ultra in a way that does not apply to other devices. Most waterproof case manufacturers simply block the S Pen slot with their enclosure, rendering the stylus permanently inaccessible while the case is on. Gorilla Cases designs the Galaxy Note 20 Ultra waterproof case with a sealed access mechanism that maintains the IP68 rating while preserving S Pen ejection and re-insertion.

Protection Tips for Your Galaxy Note 20 Ultra Waterproof Case
1. Seal the S Pen slot cover before water exposure: The S Pen slot access cover must be fully closed and latched before any water exposure to maintain IP68 integrity. Open slot covers will allow water ingress through this access point.
2. Close all port covers securely: Every port cover on the Galaxy Note 20 Ultra waterproof case must be fully closed before water contact. Inspect each cover individually before submersion.
3. Test the seal with an empty case first: Before trusting the case with your Galaxy Note 20 Ultra in water, perform a dry paper test using an empty sealed case to confirm all gaskets are intact.
4. Rinse after saltwater use: Rinse the Galaxy Note 20 Ultra waterproof case with fresh water after any ocean, bay, or brackish water exposure to prevent salt accumulation on rubber gaskets and metal components.
5. Inspect S Pen slot gasket regularly: The S Pen slot gasket receives more mechanical wear than other seals due to frequent opening and closing. Inspect it monthly for cracking or deformation and replace the case if the gasket is compromised.
6. Do not exceed rated depth or time: IP68 covers submersion to 2 meters for 30 minutes. Extended deeper submersion can force water past even intact gaskets.
7. Use the lanyard loop in whitewater or boat environments: When device loss from drops into water is a real risk, attach a lanyard through the case loop to tether the Galaxy Note 20 Ultra to your wrist or gear.
8. Clean the front membrane carefully: The integrated screen protector membrane should be cleaned with a soft microfiber cloth only. Abrasive materials can scratch the membrane surface and reduce optical clarity and touch sensitivity.
