China unveiling: July–August 2026, likely with the Xiaomi 18 series .
Beta program: The first closed beta batch in China reportedly covers the Xiaomi 17 series and Redmi K90 series .
Stable China rollout: Expected to begin in September 2026 .
Global rollout: Stable global availability is expected to start in October 2026, beginning with the Xiaomi 17 and 15 series . Some reports suggest the global version may arrive in November–December 2026 .
Official roadmap status: Xiaomi has not yet published a detailed device-by-device public rollout plan. Current device lists are based on leaks, tipster reports, and aggregated compatibility roundups .
Eligible Devices
No official final master list has been published. The following is based on aggregated leaks and tipped compatibility reports covering roughly four generations of devices across Xiaomi, Redmi, and POCO .
F series: POCO F8 Ultra, F8 Pro, F7 series (F7, F7 Pro, F7 Ultra), F6 series
X series: POCO X8 Pro, X8 Pro Max, X7 line
Other: POCO M7, POCO M7 Plus 5G, POCO C85, POCO C85 5G
Notable potential exclusions
Redmi Note 14 5G — The standard 5G variant of the Note 14 series is absent from the cited Redmi Note eligibility lists, which instead mention the 4G, Pro, Pro+, and 14S variants .
POCO M7 Pro 5G — It does not appear in the cited POCO eligibility lists, meaning its inclusion remains unconfirmed .
Key Features
"Liquid Glass" UI
HyperOS 4 is reported to introduce a complete visual overhaul dubbed “Liquid Glass.” Multiple leaks from tipster Digital Chat Station describe transparent surfaces, fluid animations, depth effects, and bounce effects across home screens and menus . The design is built on three pillars: transparent surfaces, multi-layered depth, and subsurface refraction . Reports also mention a Leica-inspired color system with themed icons and shadow/light effects .
"Zero-Legacy" architecture
HyperOS 4 is described as the first “zero-legacy” version of Xiaomi’s operating system . This means Xiaomi is removing all residual code accumulated from MIUI 1 through HyperOS 3 — a process that began with HyperOS 3.1, which removed the MIUI SDK from modules like Weather and Gallery . In HyperOS 4, the backward-compatibility layer is expected to be eliminated entirely .
Rust-rewritten core apps
Core system apps — including Settings, Phone, Messages, Gallery, and File Manager — are reportedly being rewritten from scratch using the Rust programming language . Rust is valued for its memory-safety guarantees, which reduce crashes and improve security . Multiple reports confirm this shift across key modules .
Flutter-based UI rendering
Xiaomi is adopting the Flutter UI framework for system app rendering, aiming for more consistent interfaces across different device types and screen sizes . The Flutter engine is already used in the new Weather app as of HyperOS 3.1, and HyperOS 4 will extend this across more system apps .
Expanded AI capabilities
HyperOS 4 is expected to include broader AI-driven system optimizations. Xiaomi has confirmed plans to integrate its MiClaw AI assistant more deeply into the operating system, though specific features are still being detailed in reports .
Current Uncertainty
Official naming: Xiaomi has used the phrase “new generation of OS” in public statements rather than explicitly calling it “HyperOS 4” .
Final device lists: The eligibility lists above are based on leaks, tipster reports, and compatibility roundups — not an official published roadmap .
Rollout timeline: Some sources place the reveal in the broader summer 2026 window; the July–August window is the most commonly cited .
Beta recruitment: Xiaomi has not yet formally announced a public beta program for HyperOS 4 .
