DUAL CAMERAS
The Huawei P9 has two 12-megapixel cameras around the back, “co-engineered,” the firm says, in partnership with German camera-maker Leica. One sports a monochrome (black and white) sensor, the other a traditional color (RGB) sensor, and it’s this combination Huawei says lets the camera soak up three times as much light as an equivalent single-sensor setup, producing pics with 50 percent more contrast.
