Xiaomi has released a detailed bug fix report for its C11 update, currently rolling out in China since July 28, 2026. The update improves system stability and optimizes several core apps and features. Xiaomi confirmed that these fixes will be delivered to global users in due course.
Confirmed Fixes and Improvements in C11 Update
The C11 update targets multiple Xiaomi system applications and services with a staged rollout to ensure stable user experience. Not all users receive it immediately, as Xiaomi applies a gradual “gray to full” push strategy.
Notable optimizations include improved smoothness when switching pages within the Notes app’s “To-do” section and expanded selectable ranges for “Forced rest duration” and “Continuous usage duration” settings. The update also refreshes the Game Toolbox interface with enhanced animations and a clearer real-time frame rate display.
Several bugs were addressed:
- Fixes for situations where Notes failed to sync with the cloud or where To-do reminders did not respond to taps. Users must update to Notes app version 2.4.3.1 (phone) or 2.4.3.2 (tablet).
- Resolves delayed device location updates in Family Guardian and irregular notifications from third-party apps under “Minor Mode.” The “Security Guardian Service” app requires version 3.13.07.05.00 or higher.
- Improves screen sharing by allowing users to see which app is capturing the screen and stop sharing quickly. This requires an update to the “Security Center” app version 12.7.5 or above.
- Fixes several issues with the Recorder app, including failure to download or play cloud recordings and abnormal playback sound quality.
- Other UI fixes cover anomalies in Xiaomi Smart Cards and Remote Control page displays.
- The Trip Assistant’s automatic travel logging accuracy was enhanced for easier entry.
Update Availability and Next Steps
Xiaomi encourages users to upgrade their device to verify these fixes, noting that actual results depend on practical use after installation. The company also stated it continues to handle other user feedback alongside the listed fixes.
While this bug report and bug fixes detail the update push in China, Xiaomi assures a global rollout will follow. Users can monitor update availability through system notifications and official Xiaomi communication channels.
The July 28, 2026 C11 update in China brings targeted bug fixes and optimizations to Xiaomi system apps such as Notes, Security Guardian, Game Toolbox, Recorder, and Family Guardian. Xiaomi’s staged push approach aims to maintain stability as these improvements prepare for wider, global deployment.
