Summary
August 2026 is the earliest window tipped for Xiaomi to start public beta testing of HyperOS 4, with China expected to get the update before a wider global rollout.
HyperOS 3.3 has reportedly entered internal testing on Android 17, suggesting Xiaomi is using that build to prepare the next major release rather than shipping it publicly.
Rust- and Flutter-based core changes are expected to strip out legacy MIUI code, targeting “zero legacy” design, about 40% better smoothness and up to 30% higher memory efficiency.
HyperOS 4 is also expected to add a “liquid glass” interface and upgraded AI features, while the full stable release may align with the Xiaomi 18 launch.
Xiaomi 17 models and the Redmi K90 series are tipped as early recipients, underscoring that the software overhaul is being positioned as a flagship-level upgrade.
