Galaxy S24 Ultra Waterproof Case

Why the Galaxy S24 Ultra Waterproof Case Is Essential for Beach Vacationers and Outdoor Workers

Picture your Galaxy S24 Ultra slipping out of your hand at the edge of the pool, bouncing once on the tile, and sliding straight into the deep end. With most cases, that story ends with a rice bag and a prayer. With this IP68-certified waterproof case, you fish it out, wipe it off, and keep filming. The Galaxy S24 Ultra Waterproof Case seals Samsung's 6.8-inch, 200 MP flagship inside a full-body shell of impact-resistant polycarbonate and flexible TPU, with a built-in screen protector and sealed port covers that lock out water, sand, dust, and snow.

Built for beach vacationers, kayakers, construction workers, parents of pool kids, and anyone whose phone lives a harder life than its owner, this is the best Galaxy S24 Ultra waterproof case for swimming, job sites, and travel. It is rated submersible to 6.6 ft / 2 m for 30 minutes, drop-tested to 6.6 ft / 2 m, and still supports wireless charging through the back. The Gorilla Family does not wait out the weather — and now your S24 Ultra does not either.

Key Features

• 2 color choices: classic Black and a deep ocean Blue, both with a matte, fingerprint-resistant finish.
• Premium materials: rigid polycarbonate front and back shells with a shock-absorbing TPU gasket and sealed rubber port covers.
• Case type: full-body, two-piece waterproof case that snaps together around the phone and seals with an O-ring style gasket.
• IP68 waterproof rating: certified submersible to 6.6 ft / 2 m for 30 minutes — pool drops, rainstorms, and sink accidents are no longer emergencies.
• 360-degree protection: waterproof, shockproof, dustproof, and snowproof in one sealed unit, drop-tested from 6.6 ft / 2 m.
• Built-in screen protector: an anti-scratch front membrane guards the 6.8-inch AMOLED while keeping full touch and S Pen responsiveness.
• Camera protection: a sealed, optically clear lens window shields the 200 MP camera array so underwater photos stay sharp.
• Charging compatibility: Qi wireless charging works straight through the case; this is not a MagSafe case and does not add magnets.
• Precise cutouts: accurate button covers and a sealed USB-C port flap give you full control without breaking the seal.
• Included extras: 1 case per retail package with an illustrated instruction manual for a watertight install.
• Compatibility: fits the Samsung Galaxy S24 Ultra (2024, 6.8-inch) ONLY. It does NOT fit the Galaxy S24, S24 Plus, S24 FE, S23 Ultra, or S25 Ultra.

Materials Explained — What Polycarbonate and TPU Actually Feel Like

The front and back shells are molded from polycarbonate — the same impact-resistant plastic used in bike helmets and aircraft cockpit windows. It is rigid, light, and shrugs off concrete, gravel, and boat decks without flexing onto your screen. On this case it forms the structural skeleton that keeps water pressure from reaching your phone at depth.

Wrapped around that skeleton is a TPU gasket — the flexible, grippy polymer you know from running shoe soles and hockey puck rims. TPU absorbs impact like a shock absorber, seals the two halves of the case together, and gives the edges a tactile, non-slip texture so wet hands keep their hold.

The built-in screen membrane feels close to bare glass under your thumb, and the ultrasonic fingerprint reader still works once you re-register a print through the protector. Altogether the case weighs about 3.2 oz (91 g) and adds roughly 3 mm of thickness — genuinely slim for a sealed, submersible case on a phone this large.

Real-World Use Cases

• The Beach Vacationer: shoots underwater video at the resort pool and group shots in the surf without ever thinking about salt spray.
• The Construction Worker: drops the phone off a second-story scaffold into mud, hoses it off at lunch, and clocks back in.
• The Kayaker: straps the phone to the deck for GPS tracking, knowing a capsize means a rinse, not a replacement.
• The Parent of Pool Kids: films cannonballs from the water's edge all summer while juice, sunscreen, and splashes bounce off.
• The Winter Commuter: texts through sleet and drops the phone in a snowbank at the bus stop — the sealed shell does not care.

Feature-to-Benefit Mapping

Step-by-Step Installation Guide

1. Clean your Galaxy S24 Ultra with a microfiber cloth so no dust or lint gets trapped under the built-in screen protector.
2. Open the case by releasing the corner latches and separating the front and back halves as shown in the included manual.
3. Lay the phone screen-down into the front half, then align the back half over the camera window and buttons.
4. Press around the entire perimeter until every latch clicks — run a fingernail along the seam to confirm there are no gaps, and close the USB-C port flap fully.
5. Test the buttons, speakers, and charging, then re-register your fingerprint with the phone's "Screen protector mode" enabled for reliable unlocks.

Troubleshooting and Tips

• Want to be sure it is sealed before swimming? Do a 30-minute paper-towel test: seal a tissue inside the empty case and submerge it — if the tissue is dry, you are good to go.
• Fingerprint unlock suddenly inconsistent? Delete your old prints and re-enroll them through the built-in protector with Screen protector mode on.
• Callers say you sound quiet? The fully sealed design slightly muffles audio — raise the volume a notch or two, or use speakerphone for calls in noisy places.
• Wireless charging pad not connecting? Center the phone on the coil; the 3 mm shell needs accurate alignment, and thick metal pad surrounds should be avoided.
• Cleaning after a salty or muddy day? Rinse the sealed case under fresh water and dry with a soft cloth — never scrub the membrane or finish with alcohol wipes.

FAQs

Which phones does this case fit?
It fits the Samsung Galaxy S24 Ultra (2024, 6.8-inch display) only. It does NOT fit the Galaxy S24, S24 Plus, S24 FE, S23 Ultra, or S25 Ultra — the camera layout and dimensions are different on every one of those models.

What comes in the box?
One waterproof case (front and back halves with the screen membrane pre-installed) in your chosen color, plus an illustrated instruction manual covering installation and the water-seal test.

How waterproof is it, exactly?
It carries an IP68 rating and is designed and tested for full submersion to 6.6 ft / 2 m for 30 minutes. That covers pools, lakes, rain, and accidental dunks — it is not intended for deep diving.

Does wireless charging work through the case?
Yes — Qi wireless charging passes through the sealed back. This is not a MagSafe case and does not add magnets, so magnetic mounts will not grip it.

What is the drop protection rating?
The polycarbonate and TPU shell is drop-tested from 6.6 ft / 2 m onto hard surfaces, with the sealed gasket doubling as an internal shock buffer.

Will my fingerprint sensor still work?
Yes. The ultrasonic reader works through the built-in membrane — re-register your fingerprints after installation and enable Screen protector mode for best accuracy.

Can I still use the S Pen?
The screen membrane keeps full S Pen responsiveness for notes and sketches. Open the sealed cover to remove the S Pen, and make sure every cover is fully closed again before any water exposure.

Are the buttons and ports accessible?
Yes — molded button covers press through to the real buttons, and the USB-C port sits behind a sealed flap you open for cable charging. Always close the flap before going near water.

Do I need to add a screen protector?
No. The case includes a built-in anti-scratch screen protector; adding glass on top would actually break the waterproof seal around the bezel.

Why does my audio sound slightly muffled?
The fully sealed speaker channels trade a little loudness for waterproofing. Turning the volume up one or two notches restores normal call and media levels.

Will the case yellow or fade over time?
The matte Black and Blue finishes are pigmented, not clear-coated, so they resist UV yellowing. Rinse off sunscreen and salt water promptly to keep the finish fresh.

Is it professional enough for the office?
Yes — the slim matte profile reads as a clean, rugged daily case rather than a dive housing, and it slides into work bags and jacket pockets without snagging.

Is this a good gift?
Very — for swimmers, boaters, tradespeople, and clumsy loved ones it is the rare gift that pays for itself the first time a phone hits the water. Free 30-day returns make sizing risk-free.

Can I take underwater photos with it?
Yes — the sealed lens window stays optically clear at depth. Use the volume button as a shutter, since touchscreens respond poorly underwater (a physics limitation, not a case flaw).

What is the return policy?
Yes — Gorilla Cases offers free 30-day returns on all Galaxy S24 Ultra cases. If the case doesn't fit your Galaxy S24 Ultra or you're not satisfied, contact our team within 30 days for a fast replacement or full refund. No restocking fees.

What Gorilla Family Customers Are Saying

★★★★★
Survived a full lake weekend
Took the Black one tubing on Lake Travis and my S24 Ultra spent a solid minute underwater after a wipeout. Fished it out, dried the case, zero water inside. The latches feel serious and the seal test in the manual gave me confidence before I ever got it wet.
— Marcus T., San Antonio, TX

★★★★★
Job site approved
I do concrete work and my last two phones died to dust and one fall off a ladder. This case has eaten both. The Blue looks sharp, the buttons are clicky through the covers, and wireless charging still works on my truck pad.
— Liam D., Toronto, ON, Canada

★★★★★
Pool mom essential
Two kids in swim lessons means my phone lives in the splash zone. I film every lesson from the pool edge now without the dry-bag fumbling. Fingerprint unlock worked fine after I re-registered like the instructions said.
— Renee W., Minneapolis, MN

★★★★★
Beach trip MVP
Took it to the Gold Coast for a week — sand, surf, sunscreen, no problems. Underwater photos with the volume-button shutter came out way clearer than I expected through the lens window. Feels slimmer than my mate's bulky dive case too.
— Sophie K., Melbourne, VIC, Australia

★★★★½
Brilliant seal, slightly quiet speaker
Kayak fishing every weekend and this case has been faultless in the water — drops, rain, one full capsize. Only gripe is the speaker is a bit muffled on calls, so I bump the volume up two notches. Worth it for the peace of mind.
— Owen P., Manchester, UK
