Waterproof Galaxy S20 Case - Ultimate Protection for Your Phone!

Why the Waterproof Galaxy S20 Case Is Essential for Swimmers and Outdoor Adventurers

Picture your Galaxy S20 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 waterproof Galaxy S20 case, you fish it out, wipe it off, and keep filming. This full-body sealed case wraps your Galaxy S20 (2020, 6.2-inch display) in shock-absorbing TPU and rigid polycarbonate with an IP68 waterproof rating, a built-in screen protector, and a crystal-clear back that still shows off your phone's color. Built for swimmers, kayakers, beach vacationers, construction workers, and parents of pool kids, this is the best Galaxy S20 waterproof case for anyone whose phone goes where the water is. The Gorilla Family does not wait out the weather — and now your Galaxy S20 does not either.

Key Features

• Clear-back design: a transparent polycarbonate back panel shows off your Galaxy S20's original finish while the sealed frame does the protecting.
• Premium materials: shock-absorbing high-grade TPU bumper bonded to a rigid PC shell with waterproof gaskets at every seam.
• Case type: full-body, two-piece sealed waterproof case that snaps closed around the entire phone — front, back, and edges.
• IP68 waterproof rating: tested submerged at 4.9 ft / 1.5 m for 20 minutes — pool drops, lake days, and rainstorms are no longer emergencies.
• Built-in screen protector: a sensitive integrated front membrane keeps water, sand, and grit off the display with no extra purchase needed.
• Dustproof and snowproof sealing: the same gaskets that block water keep out sand at the beach and powder on the slopes.
• Drop protection: shockproof TPU corners absorb impacts from 6.6 ft / 2 m, with a raised camera lip guarding the lens array.
• Precise cutouts and covers: sealed button covers and port plugs keep speakers, sensors, and cameras fully functional while staying watertight.
• Charging compatibility: Qi wireless charging works through the sealed back; this is not a magnetic case and does not add MagSafe.
• Lightweight build: about 2.4 oz / 68 g and roughly 3 mm of added thickness — serious sealing without the brick feel.
• Compatibility: designed for the Samsung Galaxy S20 (2020, 6.2-inch) ONLY. It does NOT fit the Galaxy S20 Plus, S20 Ultra, S20 FE, or any Galaxy S21 model.

Materials Explained — What TPU and Polycarbonate Actually Feel Like

The bumper and seals are made of TPU — thermoplastic polyurethane — the same flexible, energy-absorbing material used in running shoe soles and hockey puck rims. On this case it forms the gaskets and corner cushions, flexing on impact so your Galaxy S20's glass does not have to.

The front frame and clear back are polycarbonate, the rigid plastic found in bike helmets and aircraft cockpit windows. It resists bending and crushing, holds the waterproof seal under pressure, and keeps the back panel optically clear so your phone still looks like your phone.

The built-in screen protector is a thin, touch-sensitive membrane that feels close to bare glass — swipes, taps, and typing all register normally once the case is snapped shut. Altogether the case weighs about 2.4 oz (68 g) and adds roughly 3 mm of thickness, which is remarkably slim for a fully sealed IP68 design.

Real-World Use Cases

• The Pool Parent: films cannonballs from the shallow end all afternoon without flinching when the splash zone reaches the phone.
• The Kayaker: straps the phone to the deck for GPS tracking, knowing a capsize means a rinse, not a replacement.
• The Beach Vacationer: takes the Galaxy S20 from towel to tide line — the sealed case blocks sand from the speakers and salt spray from the ports.
• The Construction Worker: works through rain, mud, and concrete dust with a phone that wipes clean at the end of the shift.
• The Gift-Giver: needs a practical present for the friend who has already drowned one phone — this one arrives ready for the next lake trip.

Feature-to-Benefit Mapping

Step-by-Step Installation Guide

1. Clean your Galaxy S20 with a microfiber cloth so no dust or lint gets sealed inside the case.
2. Separate the front and back halves of the case and lay your phone face-down into the front frame, aligning the camera cutout.
3. Snap the back half on starting from the top edge, pressing around the perimeter until every clip clicks shut.
4. Run a fingernail around the seam to confirm the seal is fully closed, and check that the charging port plug is seated.
5. Test the buttons, speakers, and cameras, then re-register your fingerprint with "Screen protector mode" enabled in Settings for the most reliable in-display unlock.

Troubleshooting and Tips

• Touchscreen feels less responsive after install? Enable "Touch sensitivity" (Screen protector mode) in Settings > Display — it is designed exactly for built-in protectors like this one.
• Fingerprint unlock misses more than usual? Delete and re-enroll your fingerprint with the case on so the sensor learns the membrane.
• Wireless charging seems slow? Center the phone carefully on the pad — the extra 3 mm means alignment matters more than it did caseless.
• Planning a swim or snorkel session? Do a 30-minute paper-towel test first: seal a tissue inside, submerge the empty case, and check for moisture before trusting it with your phone.
• Case looking cloudy after the beach? Rinse with fresh water and dry with a soft cloth — never use alcohol wipes on the coated surfaces, as they can haze the clear back.

FAQs

Which phones does this case fit?
It fits the Samsung Galaxy S20 (2020, 6.2-inch display) only. It does NOT fit the Galaxy S20 Plus, S20 Ultra, S20 FE, or any Galaxy S21 series phone — each of those needs its own size-specific case.

What comes in the box?
One two-piece waterproof Galaxy S20 case with the screen protector membrane built into the front half. No tools are required for installation.

Does it work with wireless charging or MagSafe?
Qi wireless charging works through the sealed back, though charging may be slightly slower than caseless. This is not a magnetic case and does not add MagSafe — the Galaxy S20 itself does not support MagSafe accessories.

What is the drop protection rating?
The TPU corners and rigid frame are rated for drops from 6.6 ft / 2 m onto hard surfaces.

How waterproof is it really?
It carries an IP68 rating and was tested submerged at 4.9 ft / 1.5 m for 20 minutes. It is built for pools, lakes, rain, and snow — not for sustained deep diving.

Can I take underwater photos?
Yes — the camera windows stay optically clear underwater. Use the volume keys as a shutter button, since the touchscreen will not register input while submerged.

Will my fingerprint sensor and face unlock still work?
Yes. The in-display fingerprint reader works through the built-in protector — re-enroll your print with the case on for best results — and face unlock works normally through the front frame.

Are the buttons and ports accessible?
Yes. The power and volume keys have sealed press-through covers, and the USB-C port sits behind a hinged waterproof plug that opens for cable charging.

Do I need to add a screen protector?
No — the screen protector is built into the front half of the case. Adding a separate glass protector underneath will break the waterproof seal.

Is there a lanyard or strap option?
There is no dedicated lanyard hole on this model. For water sports we recommend a floating phone strap pouch or arm band over the sealed case.

Will the clear back yellow over time?
The polycarbonate back resists UV yellowing far better than cheap soft-TPU clear cases. Rinsing off sunscreen and salt water after beach days keeps it clear longest.

Is it professional enough for the office?
Yes — the clear back and slim 3 mm profile read as clean and minimal in meetings, not tactical or bulky.

Is this a good gift?
It is one of our most-gifted Galaxy S20 cases — practical, universally useful, and backed by free 30-day returns if the recipient already upgraded phones.

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