Essential Tips for Choosing Underwater Smartphone Housings

With the advancement of technology, capturing stunning underwater photos and videos has become more accessible than ever, thanks to underwater smartphone housings. These housings provide a protective barrier that allows you to use your smartphone underwater, capturing the beauty of marine life, underwater landscapes, and memorable moments beneath the surface. In this article, we’ll explore essential tips to help you choose the right underwater smartphone housing for your underwater photography adventures.

1. Compatibility with Your Smartphone Model

The first and most crucial factor to consider when choosing an underwater housing is its compatibility with your smartphone model. Not all housings are universal, and they are designed to fit specific smartphone models or size ranges. Before making a purchase, ensure that the housing is compatible with your smartphone’s make and model. Manufacturers often provide compatibility lists or guides on their websites, so be sure to double-check and confirm compatibility to avoid any issues later on.

2. Depth Rating and Waterproof Seal

The primary purpose of an underwater housing is to protect your smartphone from water damage while allowing you to use it underwater. Check the depth rating of the housing, which indicates the maximum depth it can safely withstand underwater. Different housings have varying depth ratings, ranging from a few meters to deeper diving depths. Determine your typical underwater photography needs and choose a housing with an appropriate depth rating to ensure reliable waterproof protection.

Additionally, inspect the housing’s waterproof seal and closure mechanism. Look for housings with robust sealing systems such as double O-rings or secure locking mechanisms to prevent water from seeping into the housing during submersion. Regularly maintain and lubricate the seals as per the manufacturer’s recommendations to maintain their integrity and waterproof performance.

3. Material and Build Quality

The durability and build quality of the underwater housing are crucial considerations, especially for prolonged or frequent underwater use. Opt for housings constructed from high-quality materials such as polycarbonate, aluminum, or stainless steel. These materials offer excellent resistance to water, corrosion, and impact, ensuring long-term protection for your smartphone.

Consider housings with reinforced corners or shock-absorbent features to safeguard your device against accidental bumps or drops underwater. Smooth and responsive buttons and controls on the housing are also essential for easy operation of your smartphone’s camera functions while submerged.

4. Optical Lens Ports and Accessories Compatibility

One of the key aspects of underwater photography is capturing clear and distortion-free images and videos. The quality of the lens port on the housing directly impacts the clarity and sharpness of your underwater shots. Look for housings with high-quality optical lens ports made from tempered glass or acrylic that are designed to minimise optical distortions, reflections, and color aberrations underwater.

Furthermore, consider the compatibility of the housing with additional accessories such as external lenses, filters, and mounts. Some housings feature interchangeable lens ports or accessory mounts that allow you to enhance your photography capabilities underwater. Check if the housing supports wide-angle, macro, or fisheye lenses to expand your creative possibilities and capture diverse underwater scenes with your smartphone.

5. Ergonomics and Handling Underwater

Using a smartphone underwater comes with unique challenges related to handling, accessibility, and usability. Evaluate the housing’s ergonomics and design features that facilitate comfortable and secure handling while submerged. Ergonomic grips, textured surfaces, and intuitive button layouts ensure better control and stability when operating your smartphone’s camera functions underwater.

Consider the size and weight of the housing, as well as its buoyancy characteristics, to achieve optimal handling and maneuverability underwater. Some housings come with optional buoyancy control accessories or attachment points for lanyards or wrist straps to prevent accidental drops and facilitate easy retrieval in water.

6. Maintenance and Care

Proper maintenance and care are essential for prolonging the lifespan and performance of your underwater smartphone housing. Rinse the housing thoroughly with fresh water after each use to remove salt, sand, or debris that can potentially damage the seals or lens port. Store the housing in a dry and protected environment away from direct sunlight and extreme temperatures.

Regularly inspect the housing’s seals, buttons, and O-rings for any signs of wear, damage, or corrosion. Lubricate the seals as recommended by the manufacturer to maintain their waterproof integrity. Follow the manufacturer’s guidelines for cleaning, storage, and maintenance to ensure that your housing remains in optimal condition for future underwater photography adventures.


Choosing the right underwater smartphone housing is essential for safely capturing stunning underwater photos and videos with your smartphone. Consider factors such as compatibility with your smartphone model, depth rating, waterproof seal quality, material and build durability, optical lens ports, ergonomics, and maintenance requirements when selecting a housing. By investing in a reliable and suitable underwater housing, you can explore the mesmerising underwater world and create unforgettable visual memories while protecting your smartphone from water damage and environmental hazards.
