When discussing natural light underwater photography with a smartphone, the issue of equipment always comes first. That's normal. But behind the debate between the latest flagship models and recent devices, there is a used market that deserves attention. The Huawei P30 Pro is one such example.

Released in 2019, this phone made an impression with its Leica optics and innovative RYYB sensor. Today, it can be found for between 50 and 120 euros on Back Market France. At that price, the temptation is real for a diver who wants to try underwater photography without investing in a 2025 flagship model.

However, by 2026, the situation has changed dramatically. Huawei now runs HarmonyOS without Google Mobile Services, which closes important doors regarding workflow. This doesn't make the phone useless, but it fundamentally changes what we can expect from it.

Here, we provide our complete evaluation based on 7 criteria, calibrated specifically for natural light underwater photography.

You can find all the compared models in our comparative guide to underwater photo smartphones 2026.

Suitable for: - Beginner divers who want to try underwater natural light photography on a budget. - Users who are satisfied with the native DNG Pro mode without third-party applications.

Not ideal for: - Photographers who want an advanced RAW workflow (HarmonyOS blocks MotionCam Pro and Blackmagic). - Divers who do long sessions in 4K (Kirin 980 and post-dive transfer are limiting factors).

The P30 Pro features four sensors from Leica Vario-Summilux. The main 40 MP sensor with a RYYB 1/1.7-inch sensor at f/1.6 remains generous for a 2019 device. In natural light underwater, this wide aperture performs well in average conditions, between 5 and 15 meters with good visibility.The ultrawide 20 MP lens with an aperture of f/2.2 and the periscope telephoto lens with 8 MP and 5x zoom complete the setup. In practice, underwater, you mainly use the main sensor. The macro ultrawide can be used for subjects less than 5 cm away, which is a real option for photographing nudibranchs. The characteristic purple-magenta flare of the RYYB sensor in backlit conditions remains a documented weakness: avoid pointing towards the surface with strong direct light.

Main Sensor: 40 MP RYYB, 1/1.7", f/1.6, OIS + AIS Ultrawide: 20 MP, 1/2.7", f/2.2, macro at 2.5 cm Telephoto: 8 MP periscope with 5x zoom, 1/4.0", f/3.4, OIS Burst Mode: approximately 10 frames per second | RAW Buffer: 5 to 8 shots before slowing down

This is where the P30 Pro loses the most points. Not because of the hardware, but because of the software.

In 2026, HarmonyOS operates without Google Mobile Services. A direct consequence is that MotionCam Pro and Blackmagic Camera cannot be installed. These two applications are the benchmarks for advanced RAW workflows on smartphones. Their absence forces you to stay within the native Huawei application.The native Pro mode offers some useful features: it exports DNG files in 10-bit format, allows for adjustable white balance in Kelvin, and provides manual ISO control up to 3200. This is functional for a basic approach. However, without a Log profile for video (the Master AI mode oversaturates colors by default), and without the granular control tools offered by third-party applications, the workflow remains limited.

The science of RYYB color underwater also introduces color shifts that require time to correct in post-processing when working with native DNG files.

RAW Format: Adobe Digital Negative (DNG), 10 bits Available Third-Party RAW Apps: None (HarmonyOS without GMS in 2026) White Balance: Adjustable in Kelvin, manually lockable Log Video: Not available | Master AI Mode: Oversaturates colors by default

File transfer after a dive is often overlooked in reviews. With the P30 Pro, it becomes a real issue.

The USB Type-C connector has limited actual data transfer speeds in everyday use. For a session of 100 RAW DNG files (each file between 25 and 40 MB), transferring to a computer can take 20 minutes or more, depending on the cable and destination storage device. When traveling or in field conditions, this is a significant inconvenience between dives.Huawei's proprietary Nano Memory card doesn't help matters: the NM format isn't designed for high-speed data transfer and requires a specific card reader that will be difficult to find in 2026. Internal storage of 128 or 256 GB remains the only viable option. Wi-Fi transfer (via HiSuite or a local network share) or using a USB-C to external SSD adapter are the preferred workarounds.

Internal Storage: 128 GB or 256 GB (UFS 2.1) Connector: USB Type-C, practically limited bandwidth Memory Card: Proprietary Nano Memory (NM), not recommended for data transfer Recommended Alternative: Wi-Fi transfer or USB-C to external SSD adapter

The Kirin 980 in the P30 Pro is a chipset from 2018. It features a passive cooling system with heat pipes and a graphene film, which was respectable for its time. When used for underwater photography in natural light, thermal issues are rarely critical.The issue arises during extended 4K recording. After 15 to 20 minutes of continuous video, thermal throttling may occur, reducing the frame rate. Diving naturally limits the duration of sessions (air supply, dive time), which mitigates this impact in practice. Note that a temperature shock between a warm phone and cold water can cause internal condensation. Allowing the phone to return to room temperature before diving is a sensible precaution.

[!WARNING] Silica gel: mandatory. Standard aluminum housing - high condensation profile in cold water. The Kirin 980 chip, from 2018, runs hotter than current generations, which exacerbates the thermal shock during immersion. Silica gel should be used systematically inside the housing before each dive below 15°C.

Tropical overheating: The Kirin 980 is less thermally efficient than chips from 2024-2025. Software overheating occurs after approximately 15 minutes of continuous 4K recording in water at 28°C - the lowest threshold in this comparison. In diving practice, short clips are standard anyway. The risk is low for still photography only.

Chipset: Kirin 980 (7 nm, 2018) Cooling: Passive, heat pipe + graphene film 4K Risk: Thermal throttling after 15-20 minutes of continuous recording IP Certification: IP68 (2 m, 30 min) - not guaranteed under pressure housing for extended periods.

With 4200 mAh, this offers a reliable capacity that covers a full dive session (90 to 120 minutes) without worry. The 40W SuperCharge allows for quick recharging between dives.

A key consideration is performance in cold water. Lithium-ion batteries experience a significant drop in voltage below 10°C. In the Mediterranean during winter or in the North Atlantic, the battery may fail prematurely if the phone has been exposed to cold water without insulation. Placing the phone in an inner pocket or an insulated pouch between dives helps maintain proper operating temperature.

Capacity: 4200 mAh Li-Ion Fast Charging: SuperCharge 40W wired Estimated Photo Session Duration: 90 to 120 minutes (in temperate conditions) Cold Water Alert: Noticeable voltage drop below 10°C

Before each dive session, remember to check your external battery. Use our portable battery comparator tool to choose the power bank that is right for your underwater housing and desired battery life.

The P30 Pro's autofocus system combines PDAF (phase detection), Laser AF, and ToF (Time of Flight). This hybrid configuration is robust, but on other platforms, it would allow for fine-grained control through third-party applications offering focus peaking or assisted manual focus.Without GMS under HarmonyOS, third-party applications that utilize these advanced features are not available. The native Pro mode provides access to basic manual focus, but without focus peaking. For small subjects moving slowly (nudibranchs, cephalopod eggs), the lack of focus peaking is noticeable. The shutter lag is estimated to be between 100 and 150 ms, which is acceptable but not among the best. The -1 point penalty for HarmonyOS restrictions on third-party autofocus applies here.

Autofocus Technology: Hybrid PDAF + Laser AF + ToF Focus Peaking: Not available natively, inaccessible via third-party apps (HarmonyOS) Manual Focus: Available in native Pro mode (touch ring) Estimated Shutter Lag: 100 to 150 ms

As of 2026, there are no dedicated rigid housings available for the Huawei P30 Pro. Manufacturers like Isotta or Nauticam have not developed a specific housing for this model, and there is currently no commercial reason to do so.

The only viable option is the universal Divevolk SeaTouch 4 Max housing. Its patented touch membrane allows you to use the native screen of the P30 Pro underwater, providing access to all camera application features. The certified depth rating is 60 meters, well beyond standard usage for natural light underwater photography.Consult our guide to waterproof phone housings for details on assembly and accessory compatibility.

Dedicated housing: None available in 2026. Recommended solution: Divevolk SeaTouch 4 Max (universal, underwater touchscreen). Divevolk certified depth: 60 meters. Approximate price of the Divevolk SeaTouch 4 Max: around €200-€250.

The housing

The Divevolk SeaTouch 4 Max accommodates most smartphones up to a certain width. Check the exact dimensions of the P30 Pro (158.3 x 73.4 mm) against the housing's specifications before ordering. Allow about twenty minutes for the initial assembly and leak tests. A universal housing requires more attention than a dedicated housing: a freshwater test is mandatory before any dive in saltwater.

To ensure your smartphone fits securely and compare interior volume, make sure to check if your model's dimensions fit in this housing.

Post-dive workflow

The limited USB transfer rate is the main bottleneck. For a session of 100 photos in DNG format, prefer transferring via Wi-Fi using the local network sharing or HiSuite (compatible with HarmonyOS) rather than a cable. If you have access to a USB-C hub with a fast SSD, the results will be better than using a direct cable connection to your computer. Plan the transfer during equipment rinsing and dive report writing.

Current prices (July 2026)

New: Discontinued - the P30 Pro has not been available new for several years.Used Market Price in France: €50 to €120 depending on condition (Good / Very Good / Excellent). Source: Back Market France, estimate as of July 2026 based on the range provided in reference specifications.

Used Option Considerations

At a price of €50-€120, the P30 Pro remains a possible entry point for those who want to try underwater photography with natural light without making a significant financial commitment. The Leica optics are truly above average for this price segment. However, the state of HarmonyOS in 2026 represents a concrete limitation: no MotionCam Pro, no Blackmagic support, and no evolution of the RAW workflow through third-party applications. If the goal is to make serious progress, this phone will quickly become limiting. If the goal is to take a few dives and photos and see if you enjoy the discipline, it's an honest option.

The 2019 Huawei P30 Pro retains something that many recent smartphones lack for their equivalent price range on the used market: a Leica lens that truly works. The 1/1.7-inch RYYB sensor with f/1.6 aperture produces DNG files that can be recovered in post-processing, and the hybrid AF system holds up well for relatively static subjects.But it's 2026, and HarmonyOS changes the game. The lack of Google Mobile Services prevents access to the entire layer of advanced RAW applications that currently form the core of a serious underwater photography workflow. Add to that the slow USB transfer speed after dives, and the Kirin 980 processor, which is showing its age in 4K video recording.

For a curious diver who wants a first experience with natural light underwater photography on a budget: acceptable. For a photographer who wants to build a practice and an evolving workflow: look elsewhere.

Final score: 2.5/5.
