HyperOS 4 Launch in August 2026: Xiaomi’s Most Reliable Update
Xiaomi is preparing for a major upgrade with HyperOS 4, set to launch in August 2026. With this update, Xiaomi plans to completely overhaul its operating system by removing all legacy MIUI code, making HyperOS 4 the first “Zero-Legacy” version. This fresh version promises a faster, more stable experience with improved performance, speed, and security.
Let’s dive into what HyperOS 4 brings to the table and how it will change the Xiaomi user experience moving forward.
HyperOS 4: A Clean Break from MIUI Legacy
One of the most significant changes coming with HyperOS 4 is the complete removal of the MIUI code that Xiaomi has used for over a decade. This is the first time Xiaomi is transitioning to a fully operating system, meaning with previous MIUI systems.

No MIUI Backward Compatibility: By removing the MIUI backward-compatibility layer, Xiaomi eliminates old system bloat, enabling a cleaner, more optimized experience.
Full Use of HyperOS SDK: From now on, all modules in HyperOS 4 will use the HyperOS SDK, ensuring consistency and better performance.
Faster, More Stable Updates: Removing outdated dependencies and old code improves update speeds and ensures stability across devices.
With these changes, HyperOS 4 promises a smoother, faster, and more stable system that eliminates the baggage of past updates.
Flutter and Rust: The New Foundations for Apps in HyperOS 4
Xiaomi has chosen to rewrite core apps using Flutter and Rust, two modern programming languages, to improve performance and security.
Why Flutter and Rust?
Flutter allows for smoother user interfaces and standard UI rendering, offering a polished, consistent experience across devices.
Rust enhances the speed, security, and stability of the underlying system, reducing bugs and improving overall reliability.
By adopting these advanced technologies, HyperOS 4 ensures that all of Xiaomi’s apps run faster and are more secure. The modular apps will now update independently, reducing the need for system-wide updates and allowing for quicker fixes and improvements.
The End of Backward Compatibility: What Does It Mean for Older Devices?
One key takeaway from HyperOS 4 is the end of backward compatibility with older versions of HyperOS and MIUI. This means that Xiaomi’s legacy phones (especially those using older MIUI versions) will no longer receive access to the latest app versions or updates designed for HyperOS 4.
However, this is a necessary step for Xiaomi to move forward and build a more robust and secure operating system. While flagship phones will see minor improvements, budget phones will benefit the most from the performance boosts, making them feel faster and more responsive.
What to Expect from HyperOS 4: Performance and Stability
With the introduction of HyperOS 4, Xiaomi is focusing on providing the most stable experience in the company’s history. This is achieved by addressing old code issues that caused slowdowns and bugs. As a result, Xiaomi users can expect the following:
Faster System Performance: With no legacy code weighing it down, HyperOS 4 will run more smoothly, especially on budget devices.
Better Stability: By focusing on Flutter and Rust, HyperOS 4 will deliver greater stability, ensuring apps load faster and the system is more responsive.
Improved Battery Efficiency: The optimized system performance, combined with faster app rendering, will also improve battery life.
Xiaomi’s move towards Flutter and Rust ensures that HyperOS 4 is a future-ready operating system that can support the growing demands of apps and services in 2026.
What Devices Will Get HyperOS 4?
While HyperOS 4 promises great benefits, the update will not be available for all Xiaomi devices. Older devices running MIUI 1 to HyperOS 3.1 won’t be able to receive this update due to architectural changes. The Xiaomi 17 series, Redmi K90, and future flagship models will be the first to get the update.
However, for older Xiaomi users, the company has ensured that HyperOS 3.1 remains functional and that security updates will continue for some time.
When Will HyperOS 4 Be Available?
HyperOS 4 is expected to roll out in August 2026. Xiaomi is likely to roll out the update first to users in select regions, starting with the Xiaomi 17 series and the Redmi K90 series. After the initial rollout, the update will gradually roll out to other supported devices.
