The Huawei Mate 9 is expected to launch with Android 7.0 Nougat out of the box, but an image posted on twitter by the official EMUI account hints that the company may announce the latest version of their user interface called Emotion UI 5.0 very soon, probably on Wednesday with the Mate 9.
Reports of a new version was first mentioned months ago when leaks were posted on Weibo by @kjuma and was even expected to launch at IFA Berlin.
The new UI will probably be the overlay on the new phone. It is said to be closer to stock android, be more colourful and will come with some new features such as an app drawer, redesigned and customizable virtual keys, and an overall simpler interface. Battery performance and phone manager are also expected to be better when the new UI launches.
EMUI 5.0’s skin was reported to have leaked a few months ago alongside a beta version of Nougat for the Huawei P9. There is no mention of the devices that will get the update When it officially launches, Huawei will most likely announce what phones will be getting the update.
