Full Definition & Technical Explanation
Sensor size is the physical light-capture area — e.g., Sensor size: 1/1.56" (≈ 0.64 inch). A larger sensor gathers more light and detail, improving low-light quality more than megapixels.
See Sensor: Sony IMX904 and Pixel size: 1 micron. Bigger is generally better in phones.
