Xiaomi has locked in an October 15, 2026 launch date for its HyperOS 4 update, initiating a sweeping phased distribution schedule that begins with flagship devices and select tablets in China, according to the technology publication DonanımHaber.
Xiaomi Rollout Waves Stretch into 2027
The rollout timeline spans multiple waves stretching into 2027. DonanımHaber reported that the initial wave on October 15, 2026, covers the Xiaomi 17 series, the Redmi K100 series, the Redmi K90 series, and the Xiaomi Pad 8 tablet lineup.
A second wave scheduled for October 31, 2026, brings the software to the Xiaomi 17 Max, Xiaomi 17T, Xiaomi 17T Pro, Redmi K90 Max, Redmi K90 Supreme Edition, and Redmi Turbo 5 series.
Subsequent deployments target November 15, 2026, for the Xiaomi 15 family, Xiaomi MIX Flip 2, Xiaomi Civi 5 Pro, and Redmi K80 series. December 2026 brings the update to older flagships including the Xiaomi 14 and 13 series, alongside foldable models like the MIX Fold 3 and 4.
Internal Beta Applications Close Before Stable Release
Technopat noted that internal beta applications for HyperOS 4 close on October 14, 2026, setting the stage for the stable release window.

The software release arrives alongside an expanded software push by the company. 12punto reported that Xiaomi recently deployed HyperOS 3 builds across 32 models to tighten system stability and patch security vulnerabilities.
Technopat added that regional variations in software support and testing programs mean global rollout schedules may differ from domestic timelines announced in China.
Super AI 2.0 Improves Application Launch Speeds
HyperOS 4 introduces system-level performance enhancements and new artificial intelligence features, incorporating Super AI 2.0 and Xiaomi’s proprietary MiMo language model, according to DonanımHaber.
Internal company tests cited by Technopat show that on a Xiaomi 17 Ultra, the total launch time for 30 applications after nine hours of continuous use dropped from 169.4 seconds on HyperOS 3 to 139.7 seconds on the new software.
Interface Features Dynamic Glass Effects
The user interface features a dynamic glass effect that alters panel transparency based on screen content, alongside a flexible floating window system.
