Galaxy S23 Ultra Waterproof Case

Why the Galaxy S23 Ultra Waterproof Case Is Essential for Swimmers and Outdoor Adventurers

Picture your Galaxy S23 Ultra slipping out of your hand at the edge of the pool — and you reaching in to grab it, still recording video. That is what IP68 certification buys you. The Galaxy S23 Ultra Waterproof Case seals Samsung's 6.8-inch flagship (2023) inside a 360-degree full-body shell that is waterproof, shockproof, dustproof, and snowproof, with a built-in screen protector and full wireless charging support. Built for swimmers, kayakers, beach vacationers, ski-trip regulars, and parents of pool kids, this is the best Galaxy S23 Ultra waterproof case for water sports and four-season abuse. The Gorilla Family does not wait out the weather — and now your S23 Ultra does not either.

Key Features

• 2 color choices: Black and Blue — clear front and back windows keep your screen and camera fully visible.
• Premium materials: rigid polycarbonate shell, shock-absorbing TPU bumper zones, and a flexible built-in screen membrane.
• Case type: full-sealed 360-degree waterproof case — front and back halves clamp together around the entire phone.
• IP68 certified: designed and tested submersible to 6.6–10 ft (2–3 m) for 30 minutes — pool, lake, surf, and snow.
• Underwater photography: the optically clear back window lets the 200 MP camera shoot photos and video below the surface.
• Screen protection: built-in anti-scratch screen protector keeps touch and S Pen response while sealing out water and grit.
• Camera protection: sealed lens window guards the camera array through 6 ft / 1.8 m drops and full submersion.
• Charging compatibility: Qi wireless charging works with the case on — no unsealing needed; note this is not a magnetic case and does not add MagSafe.
• Call-friendly sealing: acoustic membranes keep calls and speakers working — fully sealed cases run slightly quieter, so nudge the volume up.
• Included extras: retail package with illustrated instruction manual for a leak-free install on the first try.
• Compatibility: fits the Samsung Galaxy S23 Ultra 5G (2023, 6.8-inch) ONLY. It does NOT fit the Galaxy S23, S23 Plus, S22 Ultra, or S24 Ultra.

Materials Explained — What Polycarbonate and TPU Actually Feel Like

The structural shell is polycarbonate — the same impact-resistant plastic used in bike helmets and aircraft cockpit windows. It gives the case its rigid, crush-resistant skeleton and the crystal-clear back window your camera shoots through.

The perimeter and corners are TPU — the flexible, energy-eating material found in running shoe soles and hockey puck rims. It cushions drops and forms the watertight gasket line where the two halves clamp together.

The built-in front membrane is a thin, flexible screen protector that keeps full touch sensitivity — swipes, typing, and S Pen input all feel natural while the seal does its work underneath.

Altogether the case weighs about 2.5 oz (70 g) and adds roughly 3 mm of thickness — light enough for all-day carry, considering your phone can now swim.

Real-World Use Cases

• The Beach Vacationer: shoots snorkel video at 6.6 ft / 2 m and rinses the sand off the case under the shower tap afterward.
• The Kayaker: straps the phone to the deck for navigation — a capsize is a story now, not a $1,200 loss.
• The Parent of Pool Kids: films cannonballs from the water line without flinching at every splash.
• The Ski-Trip Regular: snowproof sealing means powder days and dropped-in-a-drift moments cost nothing.
• The Construction Worker: rain, mud, and concrete dust — the same seal that blocks water blocks everything else.

Feature-to-Benefit Mapping

Step-by-Step Installation Guide

1. Clean your Galaxy S23 Ultra with a microfiber cloth — trapped dust under the membrane shows forever.
2. Open the case and lay the phone face-up into the front half, aligning the screen with the built-in protector.
3. Clamp the back half on, pressing around the full perimeter until every latch point clicks.
4. Run a fingertip around the seam to confirm the gasket sits flush with no gaps — then do a 30-minute paper-towel water test before the first swim.
5. Test buttons, speakers, and wireless charging, and re-register your fingerprint through the membrane if unlock feels slow.

Troubleshooting and Tips

• Fingerprint unlock inconsistent? Re-enroll your fingerprint with the case on — the ultrasonic sensor adapts to the membrane in one pass.
• Calls sound a little muffled? Normal for a fully sealed case — turn the call and media volume up a notch or two.
• Worried about leaks? Before each water outing, do the paper-towel test: seal a tissue inside, submerge 30 minutes, check it is bone dry.
• Foggy window after temperature swings? Open the case in a dry room, wipe the inside, and let it air out before resealing.
• Cleaning after salt water? Rinse the sealed case in fresh water and dry with a soft cloth — avoid alcohol wipes, which can degrade the gasket and coatings.

FAQs

Which phones does this case fit?
It fits the Samsung Galaxy S23 Ultra 5G (2023, 6.8-inch display) only. It does NOT fit the Galaxy S23, Galaxy S23 Plus, Galaxy S22 Ultra, or Galaxy S24 Ultra — the seal depends on exact dimensions.

How waterproof is it really?
IP68 certified — designed and tested submersible to 6.6–10 ft (2–3 m) for 30 minutes. That covers pools, lakes, snorkeling, rain, and snow.

Can I take pictures underwater?
Yes — the optically clear back window is made for it. Use the volume button as a shutter, since wet touchscreens get unreliable below the surface.

What comes in the box?
One waterproof case (front and back halves) and an illustrated instruction manual in a retail package.

Does it work with MagSafe or wireless charging?
Qi wireless charging works with the case fully sealed. Honest note: this is not a magnetic case and does not add MagSafe.

What is the drop protection rating?
The 360-degree shockproof shell handles drops from 6 ft / 1.8 m — it protects on dry land just as well as in the water.

Does the fingerprint sensor work through the case?
Yes — re-register your fingerprint after installation and the in-display sensor reads through the built-in membrane reliably.

Are the buttons and ports usable?
Yes — sealed button covers keep full click feel, and the charging port sits behind a watertight flap for cable access on dry land.

Does the S Pen still work?
The screen responds to S Pen input through the membrane, and the sealed S Pen area keeps the stylus protected; remove it before submerging for best sealing practice.

Will calls sound different?
Slightly — the full seal makes speakers and mics a touch quieter. Turning the volume up a notch fully compensates.

Will the clear window yellow over time?
The polycarbonate window is treated to resist UV yellowing — rinse off sunscreen promptly, as it is the usual culprit for hazing.

Is it good for skiing and snow?
Yes — IP68 sealing is snowproof and the shell stays flexible in cold weather. Glove-friendly volume-button shutter included.

Is this a good gift?
Perfect for swimmers, boaters, and beach families — and free 30-day returns make it risk-free.

What is the return policy?
Yes — Gorilla Cases offers free 30-day returns on all Galaxy S23 Ultra cases. If the case doesn't fit your Galaxy S23 Ultra or you're not satisfied, contact our team within 30 days for a fast replacement or full refund. No restocking fees.

Can I leave it on every day?
Absolutely — at about 2.5 oz / 70 g added it works as a daily case, with the bonus that rainstorms and spilled drinks stop mattering.

What Gorilla Family Customers Are Saying

★★★★★
Survived a full lake swim
My S23 Ultra went off the dock in 6 feet of water and sat there while I dove for it. Bone dry inside the black case. The paper-towel test the manual suggests gave me the confidence to even try.
— Kevin R., Minneapolis, MN

★★★★★
Snorkel videos are unreal
Used the blue case in Cancun and shot 30 minutes of reef video at about 2 meters. The 200 MP camera through the clear window looks barely different from open air. Volume-button shutter is the trick.
— Alicia G., San Antonio, TX

★★★★★
Pool parent essential
I film my kids' swim lessons from the water every week. Splashes, dunks, sunscreen hands — nothing gets through. Wireless charging with the case still on means I literally never take it off.
— Sophie H., Melbourne, VIC, Australia

★★★★★
Four seasons, zero worries
Bought it for kayaking and ended up using it all winter on the hill. Snow, rain, one bounce down an icy driveway — the phone has no idea any of it happened.
— Graham W., Vancouver, BC, Canada

★★★★½
Waterproof champ, slightly quiet calls
It does exactly what it promises — my phone has been in the pool a dozen times. Only gripe is call audio is slightly muffled by the sealing, so I keep the volume two notches higher than before. Fair trade for a swimming phone.
— Derek M., Denver, CO
