Galaxy S20 Ultra Waterproof Case | S20 Ultra Waterproof Shockproof Case

Why the Galaxy S20 Ultra Waterproof Case Is Essential for Adventurers and Accident-Prone Owners

Picture your Galaxy S20 Ultra slipping out of your pocket at the edge of the pool while the kids chant your name from the deep end. With this case on, that moment is a story, not a tragedy. This full-body waterproof case seals your Galaxy S20 Ultra (2020, 6.9-inch Dynamic AMOLED display) inside an IP68-rated enclosure that is tested at 6.6 ft / 2 m underwater for 30 minutes, wraps it in shockproof armor that exceeds MIL-STD 810G-516, and covers the screen with a built-in protector — all without blocking wireless charging. Built for swimmers, kayakers, construction workers, beach parents, and serial phone-droppers, this is the best Galaxy S20 Ultra waterproof case for anyone whose life happens outdoors. The Gorilla Family does not wait out the weather — and now your S20 Ultra does not either.

Key Features

• 4 color choices: Black/Clear, Red/Clear, Teal/Clear, and White/Clear — a colored frame with a crystal-clear back that shows off the phone.
• Premium materials: rigid polycarbonate front and back shells with a shock-absorbing TPU bumper and precision rubber gaskets at every seam.
• Case type: two-piece full-body waterproof enclosure that snaps together around the phone and seals 360 degrees.
• IP68 waterproof rating: designed and tested at 6.6 ft (2 m) underwater for 30 minutes — and it shrugs off snow, rain, mud, and dust the rest of the year.
• Military-grade drop protection: exceeds MIL-STD 810G-516, surviving repeated drops from 6.6 ft (2 m) in lab testing — 100 drops and counting.
• Built-in screen protector: a clear front membrane guards the 6.9-inch display from scratches while keeping full touch response.
• Camera protection: the sealed clear back covers the camera module completely — you can shoot photos and video right through it, even underwater.
• Charging compatibility: Qi wireless charging works without removing the case. The USB-C port sits behind a sealed plug for wired charging — this is not a magnetic case and does not add MagSafe.
• Full button coverage: molded button covers keep power and volume clicky while staying watertight.
• Dust and snow proof: the same gaskets that keep water out also block sand at the beach and grit on the job site.
• Compatibility: precisely designed for the Samsung Galaxy S20 Ultra (2020, 6.9") ONLY. It does NOT fit the Galaxy S20, S20 Plus, S20 FE, S21 Ultra, or Note 20 Ultra.

Materials Explained — What Polycarbonate and TPU Actually Feel Like

The front and back shells are polycarbonate — the rigid, optically clear plastic used in bike helmets and aircraft cockpit windows. It gives the case its structural strength, keeps the clear back from clouding, and spreads impact force across the whole panel instead of letting it concentrate on one corner.

The perimeter bumper is thermoplastic polyurethane (TPU), the flexible, energy-eating material found in running shoe soles and hockey puck rims. It compresses on impact, which is how the case eats repeated 6.6 ft (2 m) drops without transferring the shock to your phone.

The hidden heroes are the rubber gaskets seated in channels around every seam and port — the same sealing approach used in dive housings. Altogether the case weighs about 2.8 oz (80 g) and adds roughly 3 mm of thickness — a fair trade for a phone that can survive a lake.

Real-World Use Cases

• The Beach Vacationer: shoots underwater video at the resort, lets the phone roll around in a sandy tote, and rinses the whole case off under the tap at the end of the day.
• The Kayaker: straps the phone to the deck for GPS tracking — a capsize means wiping the case dry, not visiting the rice bag.
• The Construction Worker: drops the S20 Ultra off a second-story scaffold onto gravel and picks it up without holding his breath, thanks to the MIL-STD 810G shell.
• The Pool Parent: reads at the swim lesson with total immunity to cannonball splash zones and wet-handed photo requests.
• The Winter Commuter: texts in driving snow and leaves the phone in a cup holder full of melted slush — IP68 covers snow and moisture, not just submersion.

Feature-to-Benefit Mapping

Step-by-Step Installation Guide

1. Clean your Galaxy S20 Ultra with a microfiber cloth so no grit gets trapped inside the sealed enclosure.
2. Separate the front and back halves of the case and lay the phone screen-down into the front frame.
3. Align the back half over the camera module and press around the perimeter until every clip clicks shut.
4. Run a fingernail around the seam to confirm there are no gaps, and check that the charging-port plug is seated flush.
5. Before the first swim, do the paper-towel test: seal a folded paper towel inside the empty case and submerge it for 30 minutes — if the towel is dry, your seal is perfect. Then test buttons, speakers, and touch response.

Troubleshooting and Tips

• Touchscreen feels less responsive? Enable Settings > Display > Touch sensitivity on your S20 Ultra — Samsung built that toggle exactly for screen protectors like this one.
• Fingerprint reader hit-or-miss? Re-register your thumbprint with the case installed so the ultrasonic sensor learns to read through the membrane.
• Muffled audio on calls? Check that the speaker gasket vents are free of lint — a quick rinse and air-dry restores clarity. Some slight muffling underwater is physics, not a defect.
• Wireless charging not starting? Center the phone on the pad; the extra 3 mm means alignment matters more. Remove thick metal pop-grips from the charger area.
• Cleaning after salt water? Rinse the sealed case in fresh water and dry with a soft cloth. Avoid alcohol wipes on the clear panels — they can cloud the finish over time.

FAQs

Which phones does this case fit?
It fits the Samsung Galaxy S20 Ultra (2020, 6.9-inch display) only. It does NOT fit the Galaxy S20, S20 Plus, S20 FE, S21 Ultra, or Note 20 Ultra — a waterproof seal only works with an exact dimensional match.

What comes in the box?
One two-piece waterproof case in your chosen color, a user manual with sealing instructions, and a Gorilla Cases warranty and support card.

How waterproof is it really?
It carries an IP68 rating and is tested at 6.6 ft (2 m) underwater for 30 minutes. It is built for pools, lakes, beaches, rain, and snow — it is not a scuba housing, so keep it above recreational swimming depths.

Does wireless charging work through the case?
Yes — Qi wireless charging works without removing the case. This is not a magnetic case and does not add MagSafe, which Samsung phones do not use natively anyway.

What is the drop protection rating?
The case exceeds MIL-STD 810G-516, surviving 100 lab drops from 6.6 ft (2 m). Corner bumpers absorb the worst angles.

Does the in-display fingerprint sensor work?
Yes. The built-in protector is thin enough for the S20 Ultra's ultrasonic sensor — re-register your fingerprint after installation for the most reliable reads.

Are the buttons and ports accessible?
Yes — molded covers keep the power and volume keys fully functional, and the USB-C port opens via a sealed plug. Just close the plug firmly before water exposure.

Can I add my own screen protector?
No need — the screen protector is built into the front shell. Adding tempered glass underneath would break the seal and the fit.

Can I take underwater photos?
Yes — the clear sealed back covers the lenses without distorting shots. Note that water blocks the capacitive touchscreen, so set up burst mode or use the volume key as a shutter before you submerge.

Is there a lanyard or strap attachment?
Yes — the corner of the frame includes a lanyard hole, and we strongly recommend a float strap for boating and beach days.

Will the clear back yellow over time?
The polycarbonate back resists UV yellowing far better than soft TPU clear cases. Rinse off sunscreen promptly — oxybenzone is harder on clear plastics than sunlight is.

Is it professional enough for work?
In Black/Clear it reads as a clean rugged case, and for field engineers, inspectors, and site managers the dust sealing is a workday feature, not a vacation one.

Is it a good gift?
Excellent for boaters, anglers, and anyone with a pool — and free 30-day returns cover you if the recipient carries a different phone.

What is the return policy?
Yes — Gorilla Cases offers free 30-day returns on all Galaxy S20 Ultra cases. If the case doesn't fit your Galaxy S20 Ultra or you're not satisfied, contact our team within 30 days for a fast replacement or full refund. No restocking fees.

Do I need to test the seal before swimming?
We recommend it — seal a paper towel inside the empty case and submerge for 30 minutes. Proper installation is everything with waterproof cases, and the included manual walks you through it.

Why Gorilla Cases?

We started Gorilla Cases because phone protection was either ugly and bulky or pretty and useless. The Gorilla Family trusts us because we drop-test and dunk-test every design, describe honestly — including where IP68 ends and scuba gear begins — and back every case with free 30-day returns. If your Galaxy S20 Ultra goes where the water is, this is its armor. Shop now at gorillacasestore.com
