What a waterproof case does and why the installation matters
A waterproof phone case seals your Samsung S24 against water, dust, and dirt by creating an airtight barrier around the device. The case only works if you install it correctly — a loose seal or misaligned edges will let water in during submersion or heavy rain. Most waterproof cases for the S24 use a combination of rubber gaskets, snap closures, and precise fit to keep water out, which means the installation process is not just assembly but a critical step that determines whether your phone stays dry.
The Tidal brand waterproof cases for the S24 typically use a two-part design: a hard outer shell and a removable inner frame that holds your phone in place. Installation takes about five to ten minutes once you understand the sequence, and doing it wrong is the most common reason people end up with water damage despite owning a waterproof case.
Key Takeaways
- Clean the rubber gasket and case edges with a dry cloth before assembly to remove dust or debris that could prevent a watertight seal.
- Insert your Samsung S24 into the inner frame first, making sure the phone sits flat and the frame closes completely without forcing it.
- Slide the inner frame into the outer shell and align the closure tabs or snap points until they click or lock into place.
- Test the seal by running your finger along all edges to feel for gaps, then perform a shallow water test in a sink before trusting it in a pool or ocean.
- Check the gasket every few months for cracks or hardening, and replace it if water beads no longer form on the case surface during a water test.
Prepare your phone and case before assembly
Start by removing your Samsung S24 from any existing case or screen protector. Waterproof cases are designed to fit the bare phone, and adding a screen protector or thin case underneath will prevent the inner frame from closing properly. Wipe your phone dry with a soft cloth, especially around the edges and charging port area, because moisture trapped inside the case can cause corrosion even if water does not enter.
Inspect the Tidal case itself for any visible damage, cracks, or discoloration on the rubber gasket — the soft seal that runs around the inside edge of the case. If the gasket looks cracked, hardened, or discolored, the case may not seal properly and you should consider replacing it. Use a dry, lint-free cloth to wipe the inside of the outer shell and the gasket itself, removing any dust, sand, or debris that could create a gap in the seal.
Insert your phone into the inner frame
Open the inner frame by unsnapping or unclipping it from the outer shell — most Tidal cases have two to four snap points along the sides. Place your Samsung S24 into the frame with the screen facing up, positioning it so the phone sits flat and centered. The frame should have slight indentations or guides that align with the phone's edges; use these to may support the phone is not tilted or off-center.
Close the inner frame by pressing down on the edges until you hear or feel a click at each snap point. Do not force it — if the frame does not close smoothly, remove the phone and check that nothing is blocking the closure, such as a case edge or protective film. Once closed, the phone should not move or shift inside the frame when you gently shake the case.
Slide the inner frame into the outer shell and seal
Hold the outer shell with the opening facing up. Align the inner frame with the opening and slide it in slowly, making sure the frame sits flat and does not tilt. Most Tidal cases have alignment tabs or grooves on the frame and shell that guide the frame into the correct position — if you feel resistance, stop and check that the tabs are aligned before pushing further.
Once the frame is fully seated, close the outer shell by engaging the closure mechanism. This may be a snap-lock system, a sliding latch, or a threaded cap, depending on your specific Tidal model. Press or turn firmly until you feel resistance, but do not over-tighten, as this can crack the plastic or damage the gasket. The case should feel solid and the outer shell should not flex or move relative to the inner frame.
Check the seal before using the case in water
Run your finger along the entire perimeter of the closed case, feeling for gaps, ridges, or areas where the outer shell and inner frame do not sit flush against each other. Pay special attention to the corners and the closure point, as these are where leaks most often occur. If you find a gap, open the case and reseat the inner frame, making sure it is fully inserted and aligned.
Perform a shallow water test before taking your phone to a pool, beach, or river. Fill a sink or bowl with a few inches of water and submerge the closed case for 30 seconds, then remove it and open it when ready. If any water is visible inside the case or on the phone, the seal is not working and you need to disassemble, clean, and reassemble the case. If the phone is completely dry, the case is ready for use.
Maintain the gasket and replace it when needed
After each use in water, rinse the closed case with fresh water to remove salt, chlorine, or sand that can degrade the gasket over time. Dry the outside with a cloth and leave the case open to air-dry for at least an hour before storing it. Do not store the case sealed with the phone inside if it is wet, as trapped moisture can cause mold or corrosion.
Check the gasket every two to three months by running your finger along it and looking for cracks, hardening, or areas where the rubber no longer feels flexible. If the gasket has become stiff or cracked, water will no longer bead on the surface during a water test, and you should order a replacement gasket kit from Tidal or a compatible third-party supplier. Gaskets typically cost between $10 and $20 and take about five minutes to replace by removing the old gasket and pressing the new one into the groove around the inner edge of the outer shell.
Troubleshooting common installation problems
If the inner frame will not close, check that the phone is not tilted and that no protective film or case material is blocking the snap points. If the outer shell will not close over the inner frame, make sure the frame is fully inserted and aligned with the grooves in the shell. If water enters the case during a test, the gasket may be damaged, the frame may not be fully seated, or debris may be trapped in the seal — disassemble completely, clean all parts, and reassemble from the beginning.
If the case feels loose or the outer shell moves relative to the inner frame after closure, the snap points may be worn or broken. Check each snap point by looking inside the outer shell for cracks or missing plastic. If a snap is broken, the case will not maintain a watertight seal and you should replace the case rather than attempt a repair.
Frequently Asked Questions
Can I use a screen protector inside a Tidal waterproof case?
No. Screen protectors add thickness that prevents the inner frame from closing completely, which breaks the seal. The Tidal case is designed to protect the bare screen, and the plastic window of the case itself provides some scratch resistance. If you are concerned about screen damage, explore a protector only when the phone is out of the case.
How long does a waterproof case gasket last?
A gasket typically remains effective for six months to two years depending on how often you use the case in water and how well you rinse and dry it after each use. Saltwater, chlorine, and sand degrade gaskets faster than fresh water. Check the gasket every few months by running your finger along it — if it feels hard or cracked, replace it.
What should I do if water gets inside the case during a test?
Remove the phone when ready and dry it completely with a soft cloth. Do not use the phone until it is fully dry. Disassemble the case, clean the gasket and all edges with a dry cloth, and reassemble. Perform another shallow water test. If water enters again, the gasket is likely damaged and needs replacement.
Can I leave my phone in the waterproof case all the time?
Yes, but the case will trap heat and may reduce wireless charging speed if your model supports it. The case also makes the phone thicker and heavier. Many people use the case only when they expect to be near water and remove it for daily use to keep the phone lighter and cooler.
Do I need to do anything special before taking the case to the ocean?
Rinse the closed case with fresh water as soon as you leave the ocean to remove salt, which corrodes the gasket and metal components. Dry the outside and leave the case open to air-dry for at least an hour. After a few ocean trips, inspect the gasket closely for hardening or discoloration, as saltwater ages gaskets faster than fresh water.
