Xiaomi 12S Ultra: World's Best Smartphone Camera Sensor

Xiaomi has announced its 12S Series, including the Ultra co-engineered with Leica.

That flagship features the world's largest smartphone sensor: a 50-megapixel 1-inch sensor behind a 23mm f/1.9 Leica lens.

The massive camera on the back of the Xiaomi 12S Ultra is centered around a Sony IMX989 1-inch sensor that uses a Quad-Bayer pixel array with individual pixels sized at 1.6μm.

After pixel binning, Xiaomi says these pixels reach a larger 3.2μm, reducing noise, extending the dynamic range, increasing light captured, and achieving better imagery in low-light conditions.

The sensor was co-developed between Sony and Xiaomi

To use the full size of the 1-inch sensor, Xiaomi leaned on Leica to develop a "sophisticated optical lens."

The primary camera is also the first Android device to support Dolby Vision HDR video recording and playback.
