The Mate 9 is Huawei latest flagship smartphone and comes with a Leica-powered dual-camera that combines a 20MP monochrome sensor with a 12MP RGB chip. Image data from both sensors is combined for optimized image quality.

The test engineers at DxOMark have now put the new technology through its paces and with a score of 85 the Mate 9 performs respectably but cannot take one of the top spots. It slots in at a joint 12th position, just behind the LG G5 and iPhone 7. It shares this spot with the LG V20, which was also recently added to DxO's mobile rankings.

In still image mode the testers liked the good detail preservation, accurate white balance and good exposure of the device but deducted points for inconsistent color in cloudy conditions, color casts with flash use and some ghosting artifacts. Video footage also showed good detail and exposure and was well-stabilized. On the downside, there is a noticeable jello effect when recording while walking and visible noise and reduced detail in low light. You can read the full report on
