HyperOS 4 Is Coming — Here’s Every Confirmed Device

June 20, 2026

Android 17 just landed on Pixels, and Xiaomi is next. But unlike most Android skin updates, HyperOS 4 isn’t a coat of paint over last year’s code. It’s being positioned as the most significant software architectural shift in the company’s history — a “Zero-Legacy” release that strips out every remaining line of MIUI-era code and rebuilds core applications from scratch in Rust and Flutter. For users on mid-range and budget Xiaomi devices, that distinction matters more than it sounds.

Summary

HyperOS 4 is confirmed for July or August announcement in China, with stable global rollout expected in October 2026, starting with the Xiaomi 17 and 15 series.
It’s built on Android 17 and marks the first Xiaomi OS release with zero remaining MIUI codebase — core apps rewritten in Rust and Flutter for performance, stability, and cross-device consistency.
New features include a Liquid Glass UI, interactive lock screen island, software-based privacy screen, MiClaw AI agent integration, and deeper cross-device multitasking.
Over 60 Xiaomi, Redmi, and POCO devices are expected to qualify — but the Redmi Note 14 5G and POCO M7 Pro 5G are confirmed exclusions.
Xiaomi hasn’t officially confirmed the name yet — “HyperOS 27” is a live alternative that could still surface at launch.

Why This Update Is Different From Every Previous One

Every Xiaomi OS update since MIUI has carried technical debt — old SDKs, legacy frameworks, code inherited from versions that predate the HyperOS branding entirely. HyperOS 4 ends that. Xiaomi is aggressively purging legacy code and replacing it with a native HyperOS architecture built in Rust for memory safety and Flutter for UI consistency across phones, tablets, foldables, and automotive platforms. The practical effect for mid-range users is real: MIUI overhead has historically hit performance hardest on modest chipsets, so the rewrite should deliver genuine gains on devices that never felt as smooth as their specs suggested.

There’s also a naming question worth flagging. Xiaomi has publicly confirmed a “new generation of OS” launching in July or August but hasn’t officially called it HyperOS 4. The name HyperOS 27 — aligning with the Android 17 base year — has emerged as a credible alternative. Don’t be surprised if the branding shifts at announcement.

What’s Actually New in HyperOS 4

The visual overhaul leads with Liquid Glass UI — transparent surfaces, fluid animations, and depth effects that replace HyperOS 3’s current design language. Xiaomi’s partnership with Leica is reportedly extending into the software layer. An interactive lock screen island brings dynamic information to the always-on display. The software-based privacy screen is an interesting technical challenge. Samsung does this in hardware on the Galaxy S26 series, and seeing Xiaomi’s software-only approach compared directly will be telling.

“HyperOS 4 is Xiaomi’s first OS release with zero remaining MIUI codebase anywhere in the system — after years of incremental cleanup, the final break from MIUI’s technical heritage is happening now.”

MiClaw AI agent integration runs deeper in HyperOS 4, embedded into system apps. This includes Notes, Gallery, Calendar, File Manager, and Browser as well. Cross-device multitasking gets smarter, background task management is optimized, and contextual AI productivity features are expected across daily workflows.

First Devices, Beta Timeline, and Exclusions

The first HyperOS 4 beta batch in China covers the Xiaomi 17, Xiaomi 17 Pro, Xiaomi 17 Pro Max, Xiaomi 17 Ultra, Xiaomi 17 Max, Redmi K90, Redmi K90 Pro Max, and Redmi K90 Pro Max Champion Edition. Stable rollout begins in September 2026 with the Xiaomi 17 and 15 series, followed by POCO and Redmi K-series, with the broader rollout completing by year-end. Global devices typically follow four to six weeks behind China.

Two notable exclusions: the Redmi Note 14 5G and POCO M7 Pro 5G won’t be getting HyperOS 4. Both devices were launched on Android 14 with a two-major-update commitment, meaning their support lifecycle ends with HyperOS 3. If you’re on either device, that’s worth factoring into your next upgrade decision now.
