EMUI 10 is based on Android 10 and brings in Dark Mode to the Huawei Y9 Prime (2019) along with a color scheme inspired by Morandi Color as well as Magazine Design, which seamlessly curates the on-screen content into a design similar to a magazine.
Besides, the update brings in new animations with instant feedback, smooth movements, and impressive response times.
EMUI 10 is currently rolling in India and you can download it on your Y9 Prime (2019) through the HiCare app.
I hope the EMUI 10 will soon be available here in the Philippines. :)
