Have you ever wanted to record videos or take photos underwater without having to invest in a professional or action camera? Capturing unique memories of your aquatic adventures is possible thanks to a range of cases and covers that transform your phone into a genuine underwater camera. The current market offers various options to make this a reality, from universal solutions to customized options for specific models. However, before you start using your smartphone underwater, there are a few key aspects you should know to ensure the safety of your device and achieve the best photographic results.
In this article, you'll find all the relevant information on how to transform your cell phone into a waterproof camera, including the most popular cases and covers, the main differences between them, risks and precautions to consider, approximate prices, and additional tips based on expert and user reviews. If you want your phone to accompany you up to 50 meters underwater and aren't afraid of getting wet with the best underwater cases on the market, here's everything you need to know.
Why is it necessary to protect your phone when using it underwater?
Many smartphones today offer some degree of water resistance, especially in the high-end range. However, this capability is primarily intended for occasional accidents (splashes, drops in the sink, rain), not for continuous use or submersion at medium or great depths . Furthermore, the touchscreen and buttons lose functionality underwater , and the pressure can cause irreparable damage to the device.
Therefore, using a suitable underwater case or housing is essential if you want to use your phone as an underwater camera safely. These cases go far beyond simple waterproof bags: they hermetically seal the device, insulate it from pressure, and allow you to control the camera using external buttons or a special app. This way, you can dive into the ocean, a pool, or even hot springs and take professional-quality photos and videos without endangering your device.
Different types of cases and solutions available for underwater cameras
There are several options on the market today to transform your smartphone into a waterproof camera. Let's review the most popular and effective ones:
Universal cases (suitable for any mobile phone)
If you're looking for versatility, universal cases are the most practical option. A prime example is the Diveroid Universal Lite , a waterproof case compatible with almost any phone model, including both iPhones and Androids of various sizes. These types of cases adjust using elastic straps and are usually slightly larger to accommodate a wider range of devices.
The Diveroid Universal Lite, for example, allows you to record video and take photos at depths of up to 15 meters and incorporates external mechanical buttons to control the camera from outside the water (since the touchscreen is unresponsive underwater). These buttons operate through a dedicated app, which also improves image quality by adjusting color and sharpness underwater. In addition, the system includes a metal heat sink to dissipate the heat generated by the phone, taking advantage of the cooler temperature of the underwater environment.
Specific covers for diving and water sports
If you're looking for more extreme experiences and plan to dive to greater depths, there are advanced cases like the Nautismart Pro . This case is designed for submersion up to 50 meters and is compatible with both iPhones and Android phones. Its airtight sealing system allows you to insert your device, secure it with a tab, and forget about leaks.
One of the distinguishing features of the Nautismart Pro is its extra-large rear viewfinder, perfectly aligned with the phone's camera, and its three front buttons that manage a special app, providing direct access to the shutter release and video and photo modes. It also offers the option of adding complementary lenses (such as a fisheye lens) to enhance underwater creativity.
Dedicated cases for iPhone models
Some brands choose to design waterproof cases tailored to specific models, especially iPhones. One example is the AxisGO family , designed for the iPhone 11, 12, and 13. These cases allow the use of the Wide, Ultra Wide, and Telephoto cameras at depths of up to 10 meters , far exceeding the devices' native water resistance. AxisGO also offers additional accessories such as grips and bags, making it easier to transport the case out of the water.
Similarly, the veteran TAT7 iPhone Scuba Case supports dives up to 30 meters and features three mechanical buttons for shooting, switching between video and photos, and quickly accessing recordings, all without exposing the device to the pressure and humidity of the underwater environment. However, once inside the case, touch interaction is unavailable: the camera app must be programmed before diving.
Vacuum waterproofing solutions
An ingenious alternative is the solution offered by Vacway , a company specializing in vacuum-sealed phone cases that securely enclose your phone without affecting image quality or device functionality . After the packaging process using specialized machines, the phone is 100% protected and fully operational, ideal for taking selfies, underwater photos, and videos, even in spas or thermal baths like those at Caldea in Andorra.
What should you keep in mind before submerging your phone?
Using a waterproof case doesn't eliminate all risks, so it's a good idea to consider these aspects before diving:
- Check case compatibility with your exact mobile model to avoid problems with closures or misaligned buttons.
- The maximum supported depth is keyNot all cases can withstand deep dives. Check the manufacturer's specified limit; if you're going to dive deeper than 10-15 meters, choose a high-end case.
- Attention to salt waterSalt is corrosive, and even if the case is watertight, prolonged exposure can affect certain components over time. Rinse and dry your equipment thoroughly after use at sea.
- Extreme temperatures and sudden changes can cause internal condensation or damage to the seals. Do not expose your phone to strong sunlight just before immersing it in cold water.
- The touch screen is usually useless underwater.. Base all control on external buttons or prepare the app before diving in.
- Back up your data Before you experiment: it never hurts to prevent a possible loss.

What if my phone already has IP67 or IP68 certification?
Many users believe that if their phone has an IP67 or IP68 rating, it can be used as an underwater camera without any additional accessories. However, these certifications are awarded under controlled laboratory conditions, with fresh water, stable temperatures, and no extra pressure . The reality underwater or in deep pools is very different, and even the smallest crack can compromise the safety of your device.
For reference, here are the approximate limits for recent iPhone models:
- IP67: Up to 30 minutes at 1 meter depth (iPhone 7, 8, X, SE 2)
- IP68: Up to 30 minutes at 2-6 meters, depending on the model (iPhone XS, 11, 12, 13, 14, 15, 16)
Remember: the warranty does not cover water damage . No matter how much the manufacturer advertises water resistance, using your phone as an underwater camera always carries some risk, and the right case is the best investment to avoid problems.
Additional risks and precautions
- Pressure increases with depth: and may manipulate the seals on the sleeve. Never exceed the maximum recommended depth.
- Salt water can cause long-term damage: Clean and dry the case and phone thoroughly immediately after each use.
- Condensation and sudden changes in temperature may compromise the seal and internal security. Allow the phone to acclimatize before storing it in the case and submerging it.
- Touch functions may not work underwater.. Use cases that offer physical controls or compatible apps.
- Always use original accessories or those from reputable manufacturers.Don't take a chance with imitations or generic cases of dubious origin.
Features to look for in a good underwater housing
- Depth classification: essential if you are going to do serious diving.
- Real compatibility with your mobile model.
- Total insulation against water and pressure.
- Accessible and ergonomic physical controls.
- Optical quality of the lens window: so as not to lose sharpness in the photos.
- Extras such as supports, vacuum sensors, grips or the possibility of mounting additional lenses.
Are they worthwhile as an alternative to a professional underwater camera?
For those looking to capture memories on trips, casual dives, or beach vacations, underwater phone cases are a great and affordable option . They don't replace a professional camera in terms of manual control, parameter adjustments, or image quality in extreme conditions, but they unlock the full potential of your smartphone underwater and allow you to share your moments in real time on social media.
For frequent use, demanding water sports, or if you need optimal results with every shot, advanced underwater cameras (like the Olympus Tough TG-6 or GoPros with a specific housing) or a DSLR with a dedicated housing are still recommended. However, advancements in phone cases and covers have significantly narrowed the gap, and it's now possible to capture spectacular images with the equipment you carry in your pocket.
