Unlike the standard Mate 9 that sports a 5.9-inch full HD (1080p) display, the Pro version comes with a smaller 5.5-inch dual edge curved display that supports a better Quad HD (2560 x 1440 pixels) resolution.
Furthermore, the fingerprint sensor on the back of the regular Mate 9 has been moved in the front in the Mate 9 Pro model. It's been positioned under the Home button, so some may find it easier to use now.
The rest of the phone's specs remain the same, including the Kirin 960 chipset, dual-camera setup, amount of RAM and battery size (4,000 mAh). However, the Mate 9 Pro will cost slightly more than the standard model.
According to Huawei, the Mate 9 Pro will be available for purchase in China for $685 (4GB RAM + 64GB ROM) or $775 (6GB RAM + 128GB ROM). Unfortunately for the elitists, Huawei did not announce a 6GB RAM + 256GB ROM version of Mate 9 Pro, which was rumored to cost around $835 outright.
Huawei did not say anything about the Mate 9 Pro's availability in other countries, so we can't tell whether or not it will be launched in other regions in the coming months.
