Galaxy A11 Waterproof Case

Why the Galaxy A11 Waterproof Case Is Essential for Water Lovers and Accident-Prone Hands

Picture your Galaxy A11 bobbing toward the bottom of the deep end while you stand frozen at the pool's edge. With this IP68 waterproof case sealed around it, you swim down, grab it, and check your photos on the way back up. The two-piece sealed shell wraps your A11 (2020, 6.4-inch Infinity-O display) in military-grade waterproof, shockproof, dustproof armor with a crystal-clear built-in screen protector — rated for submersion to 10 ft / 3 m for 30 minutes, or 6.6 ft / 2 m for a full hour. Built for swimmers, beach vacationers, river rafters, jobsite crews, and parents of phone-flinging toddlers, this is the best Galaxy A11 waterproof case for taking your phone where the fun actually happens. Welcome to the Gorilla Family.

Key Features

• 2 color choices: Black and Gray sealing frames, each with a clear back panel that shows the true color of your A11.
• Premium materials: flexible TPU sealing gasket fused to a rigid hard-plastic frame with a scratch-resistant clear back.
• Case type: full-body, fully sealed waterproof case — front and back covers snap together in seconds with no tools.
• IP68 waterproof rating: certified for submersion to 10 ft / 3 m for 30 minutes, or 6.6 ft / 2 m for a full hour.
• Shockproof and dustproof: the sealed design exceeds military-standard testing, absorbing drops of 6 ft / 1.8 m while locking out sand and dust.
• Underwater photography ready: shoot photos and video below the surface through the optically clear lens window.
• Screen protection: crystal-clear built-in screen protector blocks scratches without reducing touch sensitivity.
• Precise buttons and ports: molded button covers and sealed flaps follow the A11's exact lines — charge without removing the case.
• Charging compatibility: charge by USB-C through the watertight flap; this is not a magnetic case and does not add MagSafe, and the Galaxy A11 does not support wireless charging.
• Slim and lightweight: about 2.8 oz / 80 g and roughly 2.6 mm added per side — easy to pocket, easy to forget.
• Compatibility: fits the Samsung Galaxy A11 (2020, 6.4-inch) ONLY. It does NOT fit the Galaxy A10, A10e, A12, or A21.

Materials Explained — What TPU and Hard Plastic Actually Feel Like

TPU (thermoplastic polyurethane) is the flexible, energy-absorbing polymer used in running shoe soles and hockey puck rims. On this case it forms the perimeter gasket that compresses into a watertight seal and cushions impacts — with a grippy surface that stays planted in wet hands.

The frame and back panel are hard polycarbonate-grade plastic, the same engineering material used in bike helmets and aircraft cockpit windows. It keeps the shell rigid so the seal cannot pop open during a drop, while the clear back shows off your A11 and resists scratching.

The built-in screen protector is molded into the front cover with crystal clarity — your thumb glides like it is on bare glass, and there are no bubbles or films to fight with during installation.

Altogether the case weighs about 2.8 oz (80 g) and adds roughly 2.6 mm of thickness per side — impressively light for a case rated to 10 ft / 3 m underwater.

Feature-to-Benefit Mapping

Step-by-Step Installation Guide

1. Clean your Galaxy A11 with a microfiber cloth and remove any pre-installed screen protector — the case needs flush contact to keep touch sensitivity high.
2. Separate the front and back covers at the corner notch.
3. Lay the phone screen-down into the front cover, aligning the cameras with the lens window.
4. Snap the back cover on, pressing around all four edges until every clip sits flush with no gaps.
5. Run a 30-minute empty-case dunk test with a paper towel inside, then verify buttons, USB-C charging, touch response, and re-register your fingerprint through the rear sensor membrane.

Troubleshooting and Tips

• Touch less sensitive than expected? Make sure any aftermarket screen protector was removed before installation, then press around the screen edges to release trapped air.
• Rear fingerprint reader hesitating? Re-register your fingerprints with the case on — the thin membrane over the rear sensor reads reliably once retrained.
• Muffled audio on calls? The waterproof speaker membranes need a few days of break-in; clarity improves with use.
• Planning a deep swim? Stay within 10 ft / 3 m for 30 minutes or 6.6 ft / 2 m for 1 hour, and always close the port flap firmly first.
• Cleaning the case? Rinse with fresh water after beach or pool days and dry with a soft cloth — never use alcohol wipes, which degrade the gasket seals and clear coating.

FAQs

Which phones does this case fit?
It fits the Samsung Galaxy A11 (2020, 6.4-inch display) only. It does NOT fit the Galaxy A10, A10e, A12, or A21 — their dimensions and camera layouts differ enough to break the watertight seal.

What comes in the box?
The two-piece waterproof case: a front cover with built-in crystal-clear screen protector and a snap-on sealed back cover.

How deep can it actually go?
It is IP68 certified for 10 ft / 3 m of submersion for 30 minutes, or 6.6 ft / 2 m for a full hour — enough for pools, lakes, and snorkeling in the shallows.

Does it work with wireless charging or MagSafe?
The Galaxy A11 does not support wireless charging, and this is not a magnetic case and does not add MagSafe. Charge by USB-C through the sealed flap without removing the case.

What is the drop protection rating?
The sealed TPU and hard-plastic shell exceeds military-standard drop testing and protects from drops of 6 ft / 1.8 m onto hard surfaces.

Does the fingerprint sensor still work?
Yes — the A11's rear-mounted fingerprint reader works through the thin sealed membrane on the back cover. Re-register your prints after installation for the most reliable unlocks.

Are buttons and ports accessible?
Yes — the molded button covers and sealed flaps follow the A11's exact lines, so power, volume, USB-C, and the headphone jack all stay usable.

Can I keep my own screen protector on?
No — remove any pre-installed protector before use. The built-in protector needs direct contact with the screen to preserve touch sensitivity and the watertight seal.

Is there a lanyard or strap option?
The case includes a molded anchor point at the corner that accepts standard wrist and neck lanyards.

Will the clear back yellow over time?
The hard polycarbonate back resists yellowing far better than soft clear cases — rinse off sunscreen promptly and avoid alcohol wipes to keep it crystal clear.

Is it professional enough for work?
The Black version reads as clean, no-nonsense field gear — popular with couriers, site supervisors, and anyone whose phone clocks in with them.

Can I take pictures underwater?
Yes — that is half the fun. The lens window is optically clear, and below about 3 ft / 1 m the volume-button shutter is more reliable than the touchscreen.

Is it a good gift?
It is a favorite for teens, travelers, and grandparents alike — and free 30-day returns mean the wrong color guess costs nothing.

How much bulk does it add?
About 2.8 oz / 80 g and roughly 2.6 mm per side — dramatically slimmer than a dry pouch, and it still slides into a jeans pocket.

What is the return policy?
Yes — Gorilla Cases offers free 30-day returns on all Galaxy A11 cases. If the case doesn't fit your Galaxy A11 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

★★★★★
Deep-end rescue, zero damage
My son knocked my A11 into the deep end at the community pool. It sat at nine feet for a couple of minutes before I got to it — bone dry inside the Black case. The underwater video he took on the way down is now a family classic.
— Felicia R., Charlotte, NC

★★★★★
Rafting trip approved
Took this down the Ottawa River on a weekend rafting trip. The phone got soaked, dunked, and bounced off the raft floor all day, and the Gray case never let a drop in. Buttons stayed clicky even soaking wet.
— Liam K., Ottawa, ON, Canada

★★★★★
Survives my landscaping crew
Mud, sprinklers, gravel — my phone sees it all. Six months in, the case rinses clean every night and the screen has zero scratches under the built-in protector. Charging through the flap without taking the case off is the underrated feature.
— Marco V., Fresno, CA

★★★★★
Tide-pool photographer
I take my grandkids to the rock pools every summer and this case turned my A11 into our underwater camera. Photos come out sharp through the lens window and the clear back still looks new after a season of salt water and sunscreen.
— June W., Brighton, UK

★★★★½
Brilliant seal, fingerprint needed retraining
The waterproofing is flawless — passed my paper-towel test and a real bathtub incident. I did have to re-register my fingerprint twice before the rear sensor read consistently through the membrane, hence the half star. Everything else is exactly as advertised.
— Derek H., Madison, WI
