Galaxy S26 Plus: Why Flagship Cameras Struggle with Sensor Limitations

Flagship smartphones with multi-camera systems offer users extensive photography capabilities, but mid-range models often fail to match top-tier solutions. An Android Authority expert tested the Galaxy S26 Plus in low-light conditions and identified key flaws in its camera system.

The primary issue with the Galaxy S26 Plus is its sensor size. The main module features a 1/1.56-inch sensor, 40% smaller than the Galaxy S26 Ultra’s 1/1.3-inch sensor. For comparison, the iPhone 17 Pro and Pixel 11 Pro use 1/1.28-inch and 1/1.3-inch sensors, respectively. Smaller sensors limit light capture, a critical drawback in low-light conditions.

Testing revealed that even with night mode enabled, the Galaxy S26 Plus lags behind the OPPO Find X9 Ultra, which features 1/1.12-inch and 1/1.28-inch sensors. Samsung’s images exhibit noise, blurred shadows, and limited dynamic range. The Galaxy S26 Plus also requires longer exposure times (4 seconds vs. 3 for OPPO), increasing motion blur risk.

The telephoto lens on the Galaxy S26 Plus performed particularly poorly. In low light, the device automatically switches to a cropped main sensor, as the tiny 1/3.94-inch telephoto sensor fails to deliver. Resulting images are blurry, lack detail, and suffer from distorted colors. The OPPO Find X9 Ultra, by contrast, maintains sharpness and natural colors even when zooming.

Experts emphasize that when selecting a flagship smartphone, buyers should prioritize sensor size over megapixel count or aperture. A weak module in a multi-camera system can severely limit mobile photography, especially in challenging lighting conditions.
