Why the Galaxy A42 5G Waterproof Case Is Essential for Weekend Adventurers and Working Hands
Picture your Galaxy A42 5G skittering across the boat deck and stopping half an inch from the scuppers — then picture not caring, because it is sealed inside an IP68 waterproof case. The two-piece snap-together shell wraps your A42 5G (2020, 6.6-inch Super AMOLED) in fully sealed TPU and hard-plastic armor with a built-in HD screen protector, rated for submersion at 6.6 ft / 2 m for a full hour and proven across more than 1,000 underwater test cycles. Built for boaters, beach vacationers, trade crews, gym-bag commuters, and parents of splash-happy kids, this is the best Galaxy A42 5G waterproof case for turning Samsung's budget 5G workhorse into an all-weather companion. Welcome to the Gorilla Family.
Key Features
- Clean, classic colorway: a black sealing frame with a crystal-clear back panel that shows off the A42 5G's prism-dot finish.
- Premium materials: impact-absorbing TPU gasket bumper fused to a rigid hard-plastic frame with a clear polycarbonate back.
- Case type: full-body, fully sealed waterproof case — front and back covers snap together in seconds, no tools required.
- IP68 waterproof rating: certified for submersion to 6.6 ft / 2 m for 1 hour, validated across 1,000+ underwater test cycles.
- Shockproof and dustproof: the sealed design exceeds military-standard testing, absorbing drops from 6 ft / 1.8 m while locking out sand and grit.
- Included lanyard strap: a wrist strap ships in the box, keeping the case tethered on docks, lifts, and ladders.
- Screen protection: built-in HD plastic screen protector guards the big Super AMOLED display without dulling touch response.
- Camera protection: sealed optically clear lens window covers the quad-camera module, ready for underwater photos.
- Charging compatibility: charge by USB-C through the watertight flap; this is not a magnetic case and does not add MagSafe, and the Galaxy A42 5G does not support wireless charging.
- Slim sealed body: at 17.6 x 8.6 x 1.4 cm, it adds far less bulk than a dry pouch and still pockets easily.
- Compatibility: fits the Samsung Galaxy A42 5G (2020, 6.6-inch) ONLY. It does NOT fit the Galaxy A41, A32, A51, or A52.
Materials Explained — What TPU and Hard Polycarbonate 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 corner impacts, with a grippy texture that stays secure in wet hands.
The frame and back panel are hard polycarbonate-grade plastic, the engineering material found in bike helmets and aircraft cockpit windows. It keeps the shell rigid so the seal cannot flex open mid-drop, while the clear back resists scratches and lets the A42 5G's shimmering finish show through.
The built-in HD screen protector is part of the sealed front cover and sits flush against the display — no bubbles, no peeling corners, and swiping that feels close to bare glass.
Altogether the case weighs about 2.8 oz (80 g) and adds roughly 2.8 mm of thickness per side — light for a case that lets your phone swim.

Step-by-Step Installation Guide
- Clean your Galaxy A42 5G with a microfiber cloth so no dust or lint gets sealed inside the case.
- Separate the front and back covers at the corner notch.
- Lay the phone screen-down into the front cover, aligning the quad-camera with the lens window.
- Snap the back cover on, pressing around all four edges until every clip sits flush with no gaps.
- 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 built-in protector.
Troubleshooting and Tips
- In-display fingerprint reader hesitating? Delete and re-register your prints with the case installed — the A42 5G's optical sensor reads reliably through the thin protector once retrained.
- Touch feels spongy after installation? Press gently around the screen edges to release trapped air between the protector and the display.
- Calls sound muffled the first week? The waterproof acoustic membranes need a short break-in; clarity improves noticeably after a few days.
- Port flap stiff to open? That resistance is the seal working — lift from the notch with a fingernail and always press it fully closed before water exposure.
- Cleaning the case? Rinse with fresh water after beach, lake, or jobsite use 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 A42 5G (2020, 6.6-inch display) only. It does NOT fit the Galaxy A41, A32, A51, or A52 — their dimensions and camera layouts differ enough to break the watertight seal.
What comes in the box?
The two-piece waterproof case (front cover with built-in screen protector plus snap-on back cover) and a wrist lanyard strap.
Is it genuinely submersible?
Yes — IP68 certified for full submersion at 6.6 ft / 2 m for up to 1 hour, validated across more than 1,000 underwater test cycles.
Does it work with wireless charging or MagSafe?
The Galaxy A42 5G 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.
What is the drop protection rating?
The sealed TPU and polycarbonate shell exceeds military-standard drop testing and protects from drops of 6 ft / 1.8 m onto hard surfaces.
Does the in-display fingerprint sensor still work?
Yes — the A42 5G's optical under-display reader works through the built-in protector. Re-register your fingerprints after installation for the fastest unlocks.
Are buttons and ports accessible?
Power and volume click through responsive sealed covers, and the USB-C and headphone jack openings sit behind watertight flaps.
Can I keep my own screen protector on?
No — remove any aftermarket protector before installing. The case includes its own HD protector and needs flush contact to seal and keep the fingerprint reader accurate.
Is there a lanyard or strap option?
Yes, the included wrist strap attaches to the molded anchor point on the corner of the case.
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 transparent.
Is it professional enough for work?
Yes — the black-and-clear design reads as capable field gear, equally at home on a jobsite clipboard or a conference table.
Can I take underwater photos with it?
Yes — the lens window is optically clear and the touchscreen works at shallow depths; below about 3 ft / 1 m, use the volume button as your shutter.
Is it a good gift?
It is one of the most practical gifts for an A42 5G owner — and free 30-day returns make it risk-free if their tastes run slimmer.
How much bulk does it add?
The sealed case measures 17.6 x 8.6 x 1.4 cm and weighs about 2.8 oz / 80 g — roughly 2.8 mm per side, far slimmer than any dry pouch.
What is the return policy?
Yes — Gorilla Cases offers free 30-day returns on all Galaxy A42 5G cases. If the case doesn't fit your Galaxy A42 5G 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
★★★★★
Overboard and back again
My A42 went off the pontoon in about five feet of water while I was netting a fish. Dove in, grabbed it, perfectly dry inside. The strap now lives clipped to my shirt and the seal has passed every paper-towel test since.
— Hank W., Green Bay, WI
★★★★★
Trench-tested by an actual plumber
I fix burst mains for a living and my phone is wet five days a week. This case has been submerged, dropped on concrete, and hosed off daily for four months. The phone inside still looks like the day I unboxed it.
— Steve D., San Antonio, TX
★★★★★
Resort pool approved
Spent ten days in Cancun shooting underwater videos of the kids and the case never let me down. Touchscreen worked even with wet fingers and the clear back still shows off the phone's sparkle. Hotel guests kept asking what housing I was using.
— Marisol G., Chicago, IL
★★★★★
Brilliant for sea kayaking
I paddle every weekend and keep the A42 strapped to my deck lines in this case. It has been splashed, dunked on a capsize drill, and baked in the sun — the seal holds and the buttons still click. Could not ask for more at this price.
— Tom H., Auckland, New Zealand
★★★★½
Does the job, speaker slightly muted
Real-world waterproof — survived the bath, the dog bowl, and a rainy festival weekend. The only trade-off is the ringer sounds a touch muffled through the sealed membrane, so I rely on vibrate more. A fair price for total peace of mind.
— Becca L., Columbus, OH
