What are the new features in MIUI 9.0?

The key new features in MIUI 9 focus on smart features. There's a new smart assistant that helps you get whatever you need done (which we'll also see in the new Mi AI smart speaker), a smart app launcher that can quick-launch a relevant app based on the content shown onscreen, and a smart image search feature that lets you find pictures by keyword.

Another new feature we'd consider to be pretty smart is a new split-screen feature, which was confirmed by the company ahead of the announcement alongside a redesigned lock screen shortcut, three new themes and the removal of rarely used features in the Settings menu.

As you'd expect there are many system optimisations for a more fluid experience. At the launch event there was a focus on apps launching faster and dynamic resource allocation, but there are a great many more besides this as you'll see in the screen below.
