Xiaomi HyperOS 4 is the next major operating system update, generating serious excitement across the Xiaomi community. Built on Android 17, this upcoming release is shaping up to be far more than just a routine annual upgrade.
The Xiaomi HyperOS 4 is one of the most anticipated software upgrades of 2026. Built on Android 17, it introduces a mix of AI-driven productivity tools, enhanced privacy, and smoother performance. For Xiaomi, Redmi, and POCO users, this update is more than just a system refresh—it’s a step toward a smarter and more connected ecosystem.
What Is Xiaomi’s HyperOS 4?
Xiaomi HyperOS 4 update is the fourth generation of Xiaomi’s in-house operating system, replacing the MIUI-era software on which the brand had built its reputation for years. The journey started when Xiaomi launched HyperOS 1 back in October 2023, marking a clear break from MIUI’s aging architecture. Each version since then has pushed further in terms of design, performance, and system integration.

What makes HyperOS 4 particularly significant is its so-called “Zero-Legacy” framework. According to multiple credible leaks, Xiaomi is using this release to completely purge any remaining MIUI code from the system. Core applications and frameworks are being rewritten from scratch using Rust and Flutter, modern languages known for memory safety and cross-device UI consistency. In plain terms, this is not just a facelift. It is a deep architectural rebuild that could meaningfully improve performance, especially on mid-range hardware where MIUI overhead has historically been most felt.
The system is based on Android 17 and also supports Android 16, meaning users will benefit from Google’s platform improvements alongside Xiaomi’s custom enhancements.
HyperOS 4 Release Date & Rollout Timeline
Xiaomi has confirmed that the HyperOS 4 release date will follow its traditional staged rollout. The update will debut in China between July and August 2026, before expanding globally in September 2026. Regions like Pakistan may see the update’s availability toward the end of the year.
The HyperOS 4 rollout timeline prioritizes flagship devices first, followed by mid-range models, and finally entry-level phones and tablets. This phased approach ensures stability and allows Xiaomi to fine-tune the experience across different hardware tiers.
New Features Expected in HyperOS 4
While Xiaomi has not officially unveiled a features list, leaks from well-known sources—including leakster Digital Chat Station—point to several meaningful additions.
Liquid Glass UI Design
The visual overhaul centers on a Liquid Glass design language, featuring transparent surfaces, fluid animations, and depth effects that create a distinctly modern look. Think layered, translucent panels and smooth motion throughout the interface. This replaces the visual system carried over from HyperOS 3.
Interactive Lock Screen Island
One of the more practical additions is a new interactive lock screen island, similar in concept to Apple’s Dynamic Island but handled through software. It would display live activities, incoming notifications, music controls, and quick toggles directly on the always-on display without requiring the user to unlock the phone.
AI Integration Across the System
HyperOS 4 is expected to weave AI tools far deeper into everyday apps. The new MiClaw AI agent is rumored to assist with tasks across the Gallery, Notes, Calendar, and third-party app workflows. Smarter cross-device multitasking and context-aware productivity features are also being cited in leaked documentation.
Software-Based Privacy Screen
An interesting technical addition is a software-based privacy screen that restricts the viewing angle to reduce shoulder-surfing. This is a feature Samsung currently offers as a hardware solution on the Galaxy S26 series. Xiaomi delivering it through software alone would be a notable engineering achievement.
Performance Improvements from Zero-Legacy Architecture
Because the system is dropping old MIUI-era code entirely and rebuilding in Rust, users on mid-range and older devices may notice real-world performance improvements — faster app launches, smoother background task management, and better memory efficiency — rather than just benchmark gains.
HyperOS 4 Eligible Devices: Will Your Phone Get the Update?
This is the question most Xiaomi users have. At this point, Xiaomi has not published an official HyperOS 4 eligible devices list—but multiple sources have compiled expected compatibility based on Xiaomi’s published software update policies, AER (Android Enterprise Recommended) certification records from mi.com, and credible leaks.

The general rule is straightforward: flagship phones launched in the last four years and mid-range phones from the past couple of years stand a strong chance of qualifying. Budget phones released with HyperOS 3 pre-installed may also be included. Here is a breakdown of what to expect by category:
Xiaomi Flagship Series
The following devices are widely expected to receive HyperOS 4:
• Xiaomi 17, 17 Pro, 17 Pro Max, 17 Ultra, 17 Max (first beta batch confirmed by leaks)
• Xiaomi 15, 15 Pro, 15 Ultra
• Xiaomi 14, 14 Pro, 14 Ultra
• Xiaomi 13, 13 Pro, 13 Ultra, 13T, 13T Pro
• Xiaomi Mix Flip and other foldable models
Redmi Devices
Redmi users will find a broad list of expected eligible phones, particularly across the flagship K series and recent Note series:
• Redmi K90, K90 Pro, K90 Pro Max (confirmed in first beta batch)
• Redmi K80, K80 Pro
• Redmi K70, K70 Pro, K70 Ultra
• Redmi K60, K60 Pro
• Redmi Note 15 series
• Redmi Note 14 Pro and Pro+ (note: the standard Redmi Note 14 5G is expected to miss the cut)
• Newer Redmi 15 series and Redmi Pad models
POCO Devices
POCO phones expected to receive HyperOS 4 include:
• POCO F7, F7 Pro, F7 Ultra
• POCO F6, F6 Pro
• POCO X7 Pro
• POCO X6 and X6 Pro
Notably, the POCO M7 Pro 5G is expected to miss out on HyperOS 4—it was launched with Android 14 and carries only a two-major-update support promise, meaning its lifecycle ends with HyperOS 3.
How to Check If Your Device Is Eligible
Until Xiaomi releases its official compatibility list, here are a few ways to get a clearer picture of where your device stands:
• Check Xiaomi’s update policy for your model on mi.com—devices with a “4 years of major updates” promise are strong candidates for HyperOS 4 if they were launched on Android 13 or later.
• Install the MemeOS Enhancer app from the Google Play Store. It displays your current Android version and your device’s end-of-life (EoL) date, which tells you whether HyperOS 4 falls within your support window.
• Keep an eye on Xiaomi’s MIUI ROM tracker and official news pages, as the company typically releases a formal list close to the announcement date.
Get Ready for a Major Software Shift?
Xiaomi HyperOS 4 is shaping up to be one of the most significant software milestones in the brand’s history. With an Android 17 foundation, a Zero-Legacy architectural overhaul, a fresh Liquid Glass visual identity, and AI features woven throughout the system, it is a genuine step forward rather than an incremental annual polish.
The announcement is expected in July or August 2026, with the global stable rollout beginning in October. Flagship Xiaomi 17 and 15 series devices lead the queue, followed by Redmi K and Note series, and a wide range of POCO phones.
