The Honor 9 comes with a Full HD 5.15-inch display, meaning that the 1,920×1,080 resolution yields a very decent 428 pixels per inch. Based on my testing the display is effective at 454 nits of brightness, meaning that the screen will be plenty bright enough to indoor use and it's very usable outdoors. But at sub 500 nits I was worried that it may battle in powerful bright direct sunlight. However, under the Display settings there's an "Increase readability under sunlight" alternative which suggests that this device supports Assertive Display.
This means that the unit can utilize real time tone mapping to raise the viewability in glowing light without needing to increase the brightness. To learn more see my article what is assertive screen and watch the movie inspection to see it in action.
You might even alter the colour temperature of the screen in the Settings menu for somewhat cooler or warmer to better suit your preferences, but for me personally the default configurations were great enough. Overall the screen is sharp and punchy and although it isn't as superior as the Mate 9 along with the P10, it's great for this price point.
One of the crucial attributes on the Huawei Honor 9 is your camera. The theory behind the dual lenses is the capacity to deliver better light sensitivity, together with the monochrome sensor promising an increase in lighting catch over regular sensors. 12 MP images are made by default but there's the choice to bump the resolution up to 20 MP. I guess this should involve some form of up-scaling of this 12 MP RGB information combined with the full resolution data in the inkjet detector.
Aside from the more conventional modes such as HDR and Panorama that there are a lot of camera modes available including a full manual mode (which offers increased control over ISO, exposure and shutter speed) and a unique shallow depth-of-field style. When using the shallow depth-of-field manner you get the additional ability of having the ability to refocus pictures post-capture. From inside the gallery you can input the refocusing style and change which object is responsible in addition to the the depth-of-field, i.e. how far off (in terms of depth) another object should be until it moves out of focus.
Huawei has also included the mild painting style, which is also located in the P10 and Mate 9. With this you can capture light paths created by things such as moving automobiles, or even the stars at the sky. The effect can be quite cool, but does demand quite stable hands, or even a tripod bracket, to find the shot to look how that you might need it.
When in PRO mode you also get some additional options on the settings page, especially the capability to store images in both RAW and JPEG formats, and an choice to enable/disable the AF additional light attribute (which essentially beams the flash LED like a torch whilst focusing on low-light conditions). Other characteristics include a 3D creator which scans in somebody's face and creates an avatar, plus shooting in monochrome.
The Honor 9 could capture video in 4K and includes Electronic Image Stabilization (EIS) for 1080p video. It encodes 4K video from H.265, which ought to help lower the size of the subsequent movie files.
