Xioami officially announced the latest operating system HyperOS 4 based on Android 17. The most noticeable difference in the interface is that the elements are now like transparent glass complete with realistic light reflections. Clearly HyperOS 4 takes inspiration from Liquid Glass iOS 26.
In addition to the glass-like elements, the focus is on better performance. According to Xiaomi, the speed of opening applications is improved by 18% compared to HyperOS 3. Resources are pre-loaded into RAM using AI to provide more responsive application response times. Also improved is the time taken to process games, launch the camera and reduce the number of lost animation frames.
The size of folders on the screen can also be changed according to the user's wishes as can be seen on HarmonyOS. Widgets can be stacked to reduce the use of space on the screen. The lock screen can also be better personalized. Elements such as the clock are now responsive to the size selected by the user and the background image used.
XiaoAI’s performance is also improved with the ability to perform document summarization, document generation, user journey planning based on given documents, product search, and more. XiaoAI uses the new Xiaomi MiMo model to support all the features similar to Gemini Intelligence.
Beta testing for HyperOS 4 begins today on the Xiaomi 17 Ultra, 17 Pro Max, Redmi K90 Pro Max, and Pad 8 Pro series before being rolled out to other devices on August 27 and September 17 in phases.
