Samsung's HP9 Sensor Is Powering Rivals, Not Samsung Phones

Samsung manufactures some of the most advanced image sensors in the world. The Galaxy S26 Ultra, its flagship smartphone, uses a three-year-old one. Meanwhile, Vivo and Xiaomi are shipping the newer HP9 sensor — and demonstrating measurable advantages in action photography, long exposure, and low-light performance as a result.

The Sensor Supply Paradox

The Galaxy S26 Ultra runs Samsung’s Isocell HP2 sensor, introduced with the S23 Ultra in 2023. Samsung sells its newer HP9 sensor to Vivo for the X300 Ultra and to Xiaomi for the 17 Ultra, where both manufacturers have deployed custom variants with results that PetaPixel’s analysis documents as superior in the specific areas — action photography, faster shutter response, automated long exposure — where sensor generation matters most.

The S26 Ultra’s telephoto sensor compounds the pattern. Its 1/3.94-inch telephoto sensor is smaller than the 1/3.54-inch sensor in the S23 Ultra, the previous generation flagship — a step backward in hardware terms relative to what competitors are using with Samsung-manufactured components.

This is not a niche finding. It means the best Samsung image sensor experience currently available in a shipping consumer device is found in a Vivo or Xiaomi phone, not a Galaxy.

Samsung’s Explanation and Its Limits

Samsung’s official position centers on “system-level optimization.” Executives acknowledge the HP9 offers very high resolution but argue that “physical factors” create integration challenges and that the company’s ProVisual Engine software pipeline compensates for the older hardware.

The argument has a structural problem: Samsung applies the same engineering expertise to both the HP9 and the HP2. If software optimization and system integration skills are what deliver final image quality, those same skills applied to newer hardware should produce better results than applying them to older hardware. Samsung has not offered an explanation for why that logic doesn’t hold in its own devices while holding for Vivo and Xiaomi.

The practical explanation is almost certainly market segmentation: Samsung sells sensors to competitors as a profitable business unit. Deploying the latest sensors in its own devices immediately would cannibalize the premium pricing differential that makes selling those sensors to competitors attractive. The Galaxy S26 Ultra carries a flagship price premium; a sensor advantage that competitors can quickly match by purchasing the same components undermines the justification for that premium.

What This Means for Camera Buyers

For photographers choosing between smartphone platforms in 2026, the sensor supply chain reality introduces a consideration that didn’t exist in the same form when Samsung’s Galaxy line reliably held the hardware generation lead. The competitive camera smartphone landscape now includes Chinese OEMs running hardware that Samsung manufactures but doesn’t deploy in its own flagship products.

That doesn’t mean the S26 Ultra is a poor camera phone. Software processing, lens quality, and the full computational photography pipeline still matter enormously — as does the Aftershoot workflow integration that many professional mobile photographers rely on for culling and editing output from any platform. But it does mean that spec-sheet comparisons need to account for sensor generation when they appear.

The camera performance hierarchy for smartphone photography is no longer equivalent to the market hierarchy for smartphone brands. A buyer choosing the best available sensor generation for action or low-light photography in 2026 should compare the Vivo X300 Ultra and Xiaomi 17 Ultra alongside the Galaxy S26 Ultra before assuming Samsung’s own flagship is the hardware leader.
