Why the Best Galaxy S20 Plus Waterproof Case Matters in 2026
The Galaxy S20 Plus is a 2020 phone with a 6.7-inch Dynamic AMOLED display, and many owners are still using it years later. A water-damaged phone at this age is often not worth repairing, which makes prevention the smart move.
A real Galaxy S20 Plus waterproof case matters because pools, rain, lakes, and beaches are where phones actually die. Gorilla Cases offers a sealed design that treats water, sand, dust, and snow as the same problem.
The best Galaxy S20 Plus waterproof case 2026 buyers pick is not a splash cover. It is a certified IP68 enclosure that you test yourself before the first swim.
10 Key Features of the Best Galaxy S20 Plus Waterproof Case
These features come straight from the Gorilla Cases product page for the Galaxy S20 Plus waterproof case.
1. IP68 waterproof certification. The case is sealed against full submersion to 6.6 ft / 2 m for up to 1 hour.
2. Built-in screen protector. A clear front membrane guards the display edge to edge while keeping full touch sensitivity.
3. Fingerprint unlock supported. The front protector is tuned for the ultrasonic in-display sensor once you re-register your prints.
4. Military-grade drop protection. The shell exceeds MIL-STD-810G-516 and withstands drops from 6.6 ft / 2 m onto hard surfaces.
5. Two-piece snap design. Front and back covers seal the entire phone in under a minute with no tools.
6. Qi wireless charging. Wireless charging works through the sealed back, and a gasketed port cover flips open for USB-C cable charging.
7. Camera protection. A sealed optical-grade window covers the camera array, keeping water out without softening photos.
8. Dust and snow sealed. The same gaskets that stop water also stop sand at the beach and grit on the job site.
9. Polycarbonate and TPU build. A rigid polycarbonate shell is paired with shock-absorbing TPU bumper edges and precision gaskets.
10. Four color choices. Black/Clear, Pink/Clear, Purple/Clear, and Teal/Clear, each with a crystal-clear back that shows off your phone.
Who the Best Galaxy S20 Plus Waterproof Case Is For
This Galaxy S20 Plus waterproof case is built for swimmers, kayakers, beach parents, construction workers, and anyone whose phone lives outdoors. If you film from the pool edge or work through rain, it is made for you.
It is also a good fit for travelers who want underwater photos in the shallows and boat owners who expect spray and the occasional overboard scare. Owners who want a daily-driver rugged case can wear it every day, since it adds about 3.5 mm.
If you own a different Samsung phone, Gorilla Cases offers separate options. The Galaxy S20 Ultra Waterproof Case, the Waterproof Galaxy S20 Case, and the Galaxy S20 FE Waterproof Case each fit only their own model.
A Galaxy S20 Plus waterproof case will not fit those phones, and theirs will not fit yours. Always confirm the exact model before you order.
Compared with a basic bumper, a Galaxy S20 Plus waterproof case trades a little thickness for sealing against water, sand, dust, and snow. Compared with carrying a dry bag, the case lets you actually use the phone, with working buttons, speakers, and cameras.
Choose the best Galaxy S20 Plus waterproof case by asking three questions. Will the phone get wet or dusty, do you need fingerprint unlock and wireless charging to keep working, and are you willing to run a quick seal test before the first swim?

An Illustrative Scenario
This is an example, not a customer story. Imagine a parent filming a kid's cannonball contest from the edge of the pool with a Galaxy S20 Plus.
A wet hand loses its grip and the phone drops into the shallow end. Because the Galaxy S20 Plus waterproof case was sealed and tested in advance, the phone is fished out dry and the video is still recording.
That is the difference a real Galaxy S20 Plus waterproof case makes: a story instead of a repair bill.
Galaxy S20 Plus Waterproof Case Protection Tips
1. Do the paper towel test. Before first use, seal an empty case with a paper towel inside and submerge it for 30 minutes to confirm the seal.
2. Remove old protectors. The case has its own built-in screen protector, and a second one underneath breaks the seal and fingerprint function.
3. Peel the shipping film. Remove the film from the inside of the front cover and the fingerprint recognition area before installing.
4. Register fingerprints with the case on. Delete old prints and re-register them after installing so the ultrasonic sensor can learn the membrane.
5. Rinse after salt or chlorine. Rinse the sealed case in fresh water and dry it with a soft cloth.
6. Avoid alcohol wipes. They degrade the gaskets and can cloud the clear back over time.
7. Retest after a big drop. Impacts can compromise the seal on any waterproof case, so repeat the 30-minute test.
8. Use the volume keys underwater. Touchscreens cannot read wet fingers reliably, so press a volume button to take photos.
What Is in the Box and How to Install
The box contains the two-piece waterproof case, with the front cover and built-in screen protector plus the back shell, and installation instructions. No tools are needed.
Clean the phone, lay it into the back shell, then align and snap the front cover on, working around the perimeter until every latch clicks. Press the charging port cover fully closed, inspect the seam for gaps, and run the 30-minute empty submersion test before trusting it near water.
If calls sound muffled, flip open the charging port cover while talking, then snap it shut before any water exposure. If you see fog inside the case, open it in a dry room and let the phone and case air out completely before resealing.
These small habits keep your Galaxy S20 Plus waterproof case performing like it did on day one, and they cost nothing.
