Test Nothing Phone 2: Underwater Photography Review and 2026 Score

When it comes to underwater photography with a smartphone, finding the right balance is key. The Nothing Phone 2, with its unique design and promise of a streamlined Android experience, caught our attention. But what about underwater, far from city lights? Does it live up to expectations? We don't rely on marketing materials. We're going to see what this phone truly offers when it comes to capturing marine life in natural light. This test is here to give you a clear, straightforward view of its actual capabilities once submerged.

Overall Score: 2.9/5

B1 - Optics & Sensor: 3.2/5

The Nothing Phone 2 features a main Sony IMX890 sensor with 50 MP. This is a respectable-sized sensor (1/1.56") with an aperture of f/1.88. In natural light, this helps capture light even at a few meters depth. Optical image stabilization (OIS) is present, which is a good feature to avoid blurry images. The ultra-wide angle lens uses a Samsung JN1 sensor with 50 MP (1/2.76") and an aperture of f/2.2. It's smaller and less performant, but it has the advantage of being able to focus for macro shots at just 4 cm, which is interesting for small subjects.

For more details: The main Sony IMX890 sensor (1/1.56", 1.0µm pixels) is a solid choice. The Samsung JN1 ultra-wide angle sensor (1/2.76", 0.64µm pixels) is more modest. Stabilization is OIS+EIS. The native ISO range isn't clearly documented for optimal low-light performance.

B2 - RAW & Colorimetry: 3.1/5The key to underwater photography is shooting in RAW format. The Nothing Phone 2 offers a RAW (DNG) mode through its Expert mode. This is a major advantage for correcting the inevitable blue cast that occurs underwater. While the bit depth isn't specified, we can expect it to be 10 or 12 bits, which is sufficient for good post-processing. However, manual white balance in video doesn't seem to offer precise Kelvin locking, making it difficult to achieve consistent color rendering. There are no advanced video codecs like Log or ProRes, nor any partnerships with recognized colorimetry brands. It uses a generic processing system.

For more details: The RAW DNG format is available. The bit depth is estimated at 10-12 bits. Manual white balance in video does not include Kelvin locking. Video codecs are H.264/H.265. No specific color profile or partnership exists.

B3 - Storage & Transfer: 2.7/5With storage options up to 512 GB, the Nothing Phone 2 offers ample capacity for a day of diving. The key thing to note is that there is no slot for an external memory card. Once the storage is full, you need to transfer files. And this is where the problem lies. The USB Type-C port is version 2.0, which means very slow transfer speeds (480 Mbps). Emptying a full card of RAW files and videos can take a long time, especially if you are on a boat between dives. This is a real hindrance to an efficient workflow.

For more details: Internal storage up to 512 GB, with no microSD expansion. USB Type-C 2.0 connector (480 Mbps). Transferring large amounts of data is slow.

B4 - Thermal & Condensation: 2.0/5

The Nothing Phone 2 is built with a glass back and an aluminum frame. This looks elegant, but it can be a problem underwater. These materials are good thermal conductors. The Snapdragon 8+ Gen 1 processor is powerful, but it generates heat. Inside a waterproof housing, this heat is trapped, which can lead to rapid overheating of the phone and, more seriously, condensation inside the housing, blurring your photos. Some users have already reported heating problems during normal use. In cold water, the thermal shock between the hot phone and the cold water further increases this risk. This is a major point of concern.For more details: Aluminum and glass frame. Snapdragon 8+ Gen 1 processor. High risk of overheating and condensation in an underwater environment, especially in cold water. IP54 resistance (splashproof), no shock certification.

B5 - Battery: 2.8/5

The Nothing Phone 2 has a battery capacity of 4700 mAh. On paper, this is acceptable. However, when diving, the intensive use of the screen, sensor, and processor for photos and videos consumes a lot of power. User reports mention inconsistent battery life and rapid discharge. For a day with multiple dives, it's important to be vigilant and likely need to plan for recharging between dives. The battery chemistry is not specified as being next-generation (Si-C or semi-solid), and the lifespan cycles are not documented for sustained performance in extreme conditions.

For more details: 4700 mAh Li-Ion battery. No advanced chemistry documented. Variable battery life depending on usage, with reports of rapid discharge. Lifespan cycles not documented.

B6 - Underwater Autofocus: 3.0/5The autofocus on the Nothing Phone 2 relies on PDAF (Phase Detection Autofocus) technology for both the main sensor and the ultra-wide angle lens. This technology is effective on the surface. Underwater, in natural light, it works, but it performs less well than systems with LiDAR or ToF, which physically measure distance and are more reliable in murky water or with low contrast. There is no mention of Focus Peaking, a helpful aid for manual focusing. The ultra-wide angle lens has the advantage of being able to focus at 4 cm, which is a plus for macro photography, but without clear visual assistance, it's more difficult to master.

For further details: PDAF autofocus on both sensors. No LiDAR or ToF. No documented Focus Peaking. The ultra-wide angle lens has a minimum focusing distance of 4 cm.

B7 - Housing: 0.0/5The biggest drawback of the Nothing Phone 2 for diving is the lack of a dedicated underwater housing. A custom-designed housing guarantees perfect waterproofing and ergonomic access to the controls. Without it, you are forced to use universal housings. These are less reliable, often bulkier, and access to the phone's functions is limited (often via generic buttons or imprecise touch membranes). This is a risk that cannot be ignored in an underwater environment. The lack of specific support for this device is a real obstacle to any serious diving use.

For more information: No rigid housings are available specifically for the Nothing Phone 2. It requires the use of universal housings, with the associated limitations in terms of reliability and ergonomics.

Housings

As we've seen, there is no dedicated rigid housing for the Nothing Phone 2. Your only option is to turn to universal housings. Brands like Divevolk offer solutions that adapt to many smartphones. However, always check compatibility in terms of dimensions and, most importantly, how you will interact with the screen underwater. Systems using touch membranes or generic buttons are often less intuitive than direct access systems or SeaTouch systems.

Field workflowThe Nothing Phone 2 can be used for underwater photography, but you need to adjust your workflow. The slow USB 2.0 transfer speed means you won't be able to quickly offload files from your phone between dives if you have a lot of RAW images and videos. Plan to do this in the evening, at the hotel. Thermal management is also something to watch out for. Avoid long shooting sessions, especially in warm water, to minimize the risk of overheating and condensation. Remember to disable Wi-Fi, Bluetooth, and mobile data once underwater to save battery power and reduce heat generation.

Important Considerations

The Nothing Phone 2 is not designed for diving. Its IP54 rating protects it from splashes, but not from submersion. The risk of overheating is real, especially if you are shooting video in 4K. The lack of a dedicated underwater housing is a significant reliability issue. If you value your phone and your memories, this is an important consideration. The autofocus quality, while acceptable, does not compare to devices with more advanced technology for the underwater environment. The absence of Kelvin locking in video is also a limitation for those seeking accurate color reproduction.

PriceThe Nothing Phone 2 is positioned in the upper mid-range category. Its new price is around €550-€600. At this price, it's important to carefully consider the pros and cons. If your budget is limited and you are willing to make compromises, it could be a good entry point. However, if underwater photography is a serious passion, there are more suitable options available, even though they may be more expensive. Buying used might be an option if you're looking for a device dedicated solely to diving, but the risks associated with waterproofing and lifespan remain the same.

The Nothing Phone 2 is an interesting phone on the surface, with a design that is sure to turn heads. Underwater, it's a different story. It has some advantages, such as its main sensor and the ability to shoot in RAW format, which is a real plus for post-processing. However, its limitations are significant: USB 2.0, delicate thermal management, and most importantly, the lack of a dedicated waterproof housing. This device requires compromises and constant vigilance. For an occasional diver who wants to have fun and learn, it might be suitable. But for regular and demanding use, you'll need to look elsewhere. The real issue in diving is reliability and performance under extreme conditions, and on these points, the Nothing Phone 2 shows its limitations.

Should I use an anti-fog treatment with this device?Yes, absolutely. With its aluminum housing, the risk of condensation in cold water (below 15 degrees Celsius) is significant. Using an anti-fog treatment (silica gel packet or insert) inside the housing is mandatory before each dive.
