How To Open A Waterproof Phone Case (The Easy & Safe Way)

Waterproof phone cases are built to protect, not to be easily opened. That’s the point, right? But when it’s time to charge your phone, clean the case, or switch devices, you might find yourself wondering: “How do I even open this thing without damaging it?”

Don’t worry — we’ve got you covered. Whether you’re using a Coralcase for iPhone, Samsung Galaxy, or Google Pixel, this guide will walk you through how to open a waterproof phone case safely, easily, and without tools you don’t already have at home.

Quick Summary

To open your waterproof phone case:

  1. Turn off your phone.

  2. Locate the opening slot on the edge of the case.

  3. Insert a coin or flat tool gently into the slot.

  4. Twist slightly to break the seal.

  5. Work around the edge and slowly lift off the cover.

  6. Remove the phone and inspect the case.

Let’s break down each step with more detail below.

What You’ll Need

You don’t need any fancy equipment. Most Coralcase users already have everything required:

  • A dry, clean surface to work on

  • A coin (nickel or quarter works best), or a plastic opening tool (included with some Coralcase models)

  • A microfiber cloth (optional, for wiping moisture or fingerprints)

Important: Prepare Before You Open

Before diving in, take a moment to prepare:

  • Turn off your phone. This protects your device from accidental button presses or internal damage.

  • Dry your hands and surface. A firm, dry grip helps prevent slipping or dropping your phone.

  • Avoid sharp tools. Knives or metal screwdrivers can damage the case or seal.

Step-by-Step: How To Open A Waterproof Phone Case

Step 1: Find The Opening Slot

Every Coralcase waterproof case has a built-in notch or groove — usually along the bottom or side edge. It’s subtle but designed specifically for opening.

Tip: Run your finger around the edge slowly — you’ll feel a slight gap or indentation. That’s your entry point.

Step 2: Insert a Coin or Opening Tool

Gently slide the coin or plastic tool into the opening slot.

Do not force it in. If there’s resistance, reposition the tool — you’re aiming for a smooth glide, not pressure.

Step 3: Twist Gently to Break the Seal

Once inserted, twist the coin slightly — like you’re turning a key. You’ll feel or hear a small pop. That’s the waterproof seal unlocking.

Some Coralcase models make a quiet “click” sound — that’s perfectly normal.

Step 4: Slide Along the Edge

Keep the tool in the groove and slowly work it around the case edge. This gradually separates the front and back parts of the case.

Don’t pry it open all at once — work one side at a time to avoid warping the case.

Step 5: Lift and Remove the Cover

Now that the seal is loose, carefully lift the front (or back) panel of the case.

Use both hands if needed to maintain balance. Your phone should come out smoothly.

Step 6: Take Out Your Phone

Gently remove your phone from the case. If there’s any condensation or moisture inside, use a microfiber cloth to wipe it down.

Brand-Specific Tips

Here’s how opening the case might vary slightly between phone models:

iPhone (All Models)

  • The case may be slightly tighter near the side button area.

  • Newer iPhones (like 13, 14, 15 series) may have a snugger fit for camera seals — be gentle when lifting near the top corner.

Samsung Galaxy

  • Galaxy devices often have curved edges — take extra care along the side.

  • Some models (S23, S24) may have firm lock tabs at the bottom. Wiggle gently to release.

Google Pixel

  • Pixel phones (especially Pixel 7, 8 series) tend to have a deeper rear camera housing. Don’t lift directly near the camera area; loosen the bottom and work upward.

Coralcase models are precision-molded — meaning the case is meant to feel tight for waterproofing. Just go slow and steady.

After Opening: Care Tips

  • Clean the case interior. Wipe any dust, watermarks, or sand that may have entered.

  • Inspect the rubber gasket/seal. Make sure it’s still in place and not stretched or damaged.

  • Let the case dry completely before reassembling — especially after swimming, beach use, or heavy rain.

Frequently Asked Questions

Q: Can I open my waterproof case by hand only?

A: You can, but it’s easier and safer with a coin or plastic tool. Using your fingers alone might warp the case edges.

Q: Will opening my case frequently reduce its waterproofing?

A: Not if you’re careful. Just avoid bending the seal or stretching the rubber gasket. Always ensure the case is sealed properly when re-closing.

Q: Can I reuse my Coralcase multiple times?

A: Yes! All Coralcase waterproof cases are made for repeated use — just clean and reseal them properly each time.

Final Tip: Always Use the Right Case for Your Model

Opening the case correctly is just part of the equation. Make sure you’re using a Coralcase designed specifically for your exact phone model. A tight, precision fit is what keeps your device protected from water, sand, and dust.
