Galaxy Note 20 Ultra Waterproof Case – Gorilla Cases

Why the Galaxy Note 20 Ultra Waterproof Case Is Essential for Adventurers and S Pen Power Users

Picture annotating a site photo with your S Pen as the rain starts sideways, then dropping the phone in a flooded trench — and picking it up, rinsing it off, and finishing the markup. The Galaxy Note 20 Ultra Waterproof Case seals your 6.9-inch flagship (2020) inside a fully sealed 360-degree shell with airtight gaskets, shock-absorbing bumpers, a built-in screen protector that still works with the S Pen, and raised crystal-clear camera protection for the Note's huge lens array. Built for hikers, swimmers, snowboarders, construction workers, and Note loyalists who use the S Pen like a third hand, this is the best Galaxy Note 20 Ultra waterproof case for taking the ultimate productivity phone into genuinely hostile conditions. The Gorilla Family does not wait out the weather — and now your Note 20 Ultra does not either.

Key Features

• 5 color choices: Black, Green, Pink, Purple, and Teal — each with the same sealed shell and clear protective panels.
• Premium materials: rigid polycarbonate shells with airtight seals and shock-absorbing TPU bumpers.
• Case type: full-body, two-piece snap-together waterproof case forming a complete 360-degree seal.
• Certified waterproof, snowproof, dustproof: sealed for underwater use to 6.6 ft / 2 m for 30 minutes — rain, pools, snow, and dust storms covered.
• Military-grade shock absorption: bumper corners absorb drops from 6.6 ft / 2 m onto hard surfaces.
• Built-in screen protector: blocks scratches and water while keeping touch control responsive — and it works perfectly with the S Pen.
• Full S Pen and port access: precise cutouts keep the stylus, speakers, and buttons usable, with a sealed plug over USB-C.
• Raised camera protection: a crystal-clear lens shield and raised bezel guard the periscope camera array without softening photos.
• Slim sealed profile: rugged protection in a pocket-friendly shape — no dry-bag bulk.
• Charging compatibility: Qi wireless charging works through the sealed back without removing the case. This is not a built-in-magnet MagSafe case — magnetic accessories will not self-align.
• Compatibility: fits the Samsung Galaxy Note 20 Ultra and Note 20 Ultra 5G (6.9-inch, 2020) ONLY. It does NOT fit the Galaxy Note 20 (6.7-inch), Note 10 Plus, S20 Ultra, or S21 Ultra.

Materials Explained — What Polycarbonate and TPU Actually Feel Like

Polycarbonate is the same impact-resistant plastic used in bike helmets and aircraft cockpit windows. Here it forms the sealed front and back shells — the rigid structure that keeps the airtight gaskets compressed evenly around your Note 20 Ultra and shrugs off scrapes from rock, concrete, and ski-lift steel.

TPU (thermoplastic polyurethane) is the flexible, grippy material you know from running shoe soles and hockey puck rims. It forms the shock-absorbing bumpers at the corners — the spots phones actually land on — and gives cold or wet hands a secure hold.

The built-in screen membrane feels close to the phone's own glass: taps, swipes, and S Pen strokes register naturally, and handwriting stays precise enough for real note-taking.

Altogether the case weighs about 2.8 oz (79 g) and adds roughly 3.5 mm of thickness — genuinely slim for a sealed case wrapped around a 6.9-inch flagship.

Real-World Use Cases

• The Outdoor Adventurer: swims, kayaks, hikes, and snowboards with the phone along — the seal treats every condition the same.
• The Construction Pro: marks up drawings with the S Pen in dust and drizzle that would end a naked phone's day.
• The Traveler: one case covers the beach leg, the mountain leg, and the rainy-city leg of the trip with no bulky add-ons.
• The Parent at the Pool: films swim lessons from the water's edge all summer without a towel standing guard.
• The Gift-Giver: needs the present for the Note 20 Ultra owner who plans to keep it forever — five colors make it personal.

Feature-to-Benefit Mapping

Step-by-Step Installation Guide

1. Clean your Galaxy Note 20 Ultra with a microfiber cloth so no dust or lint gets trapped under the built-in screen protector.
2. Lay the phone face-down into the front shell, aligning the camera block and S Pen silo first.
3. Snap the back shell on, pressing around the entire perimeter until every latch clicks — work corner to corner.
4. Run a fingernail along the seam to confirm a complete seal, especially around the USB-C plug and S Pen area.
5. Re-register your fingerprint, test the S Pen, buttons, and speakers — and before any swim, do a 30-minute paper-towel submersion test with the case empty.

Troubleshooting and Tips

• Fingerprint unlock less reliable after installation? Delete and re-register your prints with the case on — the in-display ultrasonic sensor adapts to the membrane immediately.
• S Pen strokes feel different at first? Press gently across the screen membrane to release trapped air; pen precision settles within a day.
• Wireless charger not connecting? Center the phone precisely on the pad — the added 3.5 mm means alignment matters more than on a naked phone.
• Muffled audio after the beach? Brush the acoustic membrane vents clear of sand with a dry soft brush — never poke them.
• How should I clean it? Rinse with fresh water after pool or ocean use and wipe with a damp cloth — never use alcohol wipes on the coated panels, as they can cloud the finish.

FAQs

Which phones does this case fit?
It fits the Samsung Galaxy Note 20 Ultra and Note 20 Ultra 5G (6.9-inch, 2020) only. It does NOT fit the Galaxy Note 20 (6.7-inch), Note 10 Plus, S20 Ultra, or S21 Ultra — the camera block and S Pen position differ and the seal will not close correctly.

What comes in the box?
The two-piece waterproof case (front shell with built-in screen protector plus back shell) in your chosen color, ready to install — no tools required.

Can I swim with this case on my Note 20 Ultra?
Yes — it is designed for underwater use to 6.6 ft / 2 m for 30 minutes. It is not rated for high-pressure water jets or deep diving.

Does the built-in screen protector work with the S Pen?
Yes — the membrane is tuned for both finger touch and S Pen input, so handwriting, Air Commands, and sketching all work normally.

Does wireless charging work with the case on?
Yes — the slim sealed back supports Qi wireless charging without removing the case. The case does not contain alignment magnets, so magnetic accessories will not self-center on it.

What is the drop protection rating?
The military-grade bumpers absorb drops from 6.6 ft / 2 m onto hard surfaces — about head height.

Does the lens shield reduce camera quality?
No — the raised lens protector is optically clear, so photos and video from the periscope zoom array stay sharp, even underwater.

Does the in-display fingerprint sensor still work?
Yes — re-register your fingerprints after installing the case and the ultrasonic sensor reads reliably through the membrane.

Are the buttons and ports accessible?
Yes — sealed tactile covers protect power and volume, precise cutouts serve the speakers, and the USB-C port sits behind a waterproof plug. Close it firmly before water exposure.

Is the case bulky?
No — it adds roughly 3.5 mm and stays pocket-friendly. Rugged does not have to mean brick.

Does the case muffle the speaker?
Slightly — sealed acoustic membranes keep water out while letting sound through. Calls stay clear; music loses a touch of volume, the honest cost of true sealing.

Will it yellow or fade over time?
The colored frames hide wear and the clear panels carry an anti-yellowing coating — rinse off chlorine and sunscreen and it keeps its looks.

Is it professional enough for the office?
Yes — Black reads as a clean executive case in a meeting, and the S Pen stays one click away.

Is this a good gift?
It is the definitive gift for the Note die-hard — practical, protective, and available in five colors with free 30-day returns for easy swaps.

What is the return policy?
Yes — Gorilla Cases offers free 30-day returns on all Galaxy Note 20 Ultra cases. If the case doesn't fit your Galaxy Note 20 Ultra or you're not satisfied, contact our team within 30 days for a fast replacement or full refund. No restocking fees.
