Xiaomi has announced HyperOS 4 in China, bringing a new glass-style design, faster performance, and more AI features. The public beta starts on August 14, with rollout continuing until mid-September.
The update introduces a glass UI, which takes after iOS’s Liquid Glass. Users can resize folders, group widgets, and customize lock screen clocks and notifications. Apps switch smoothly between portrait and landscape, while floating windows rotate without glitches.
Performance gets a boost. Xiaomi says apps load 18% faster after long use compared to HyperOS 3. Camera HDR processing drops from 310ms to 240ms, and cold startup times are cut by 200ms. Video playback is also optimized to avoid dropped frames.
A new Inspiration Ball lets users drag over text or images to trigger quick actions like navigation or product searches.
