Emir BardakçıXiaomi has officially started rolling out new updates for HyperOS with the December 2025 Android security patch, centered around system stability and user protection. Rollout targeting selected Redmi models in some regions brings a number of important fixes for several security vulnerabilities. These updates are part of Xiaomi’s continued software maintenance efforts under HyperOS to ensure devices remain protected against emerging threats while continuing performance consistently across various versions of Android.
Devices Receiving the December 2025 HyperOS Update
This first phase of the December 2025 security update rollout covers two Redmi smartphone models each, per region and Android version. Xiaomi is continuing its usual staged deployment approach to ensure the quality of the updates and minimize issues that may arise.

- Android Version: Android 14

These updates confirm that Xiaomi continues to support both Android 14 and Android 15 variants in parallel for its respective devices running under the HyperOS ecosystem.
What’s New in the December 2025 Security Patch
Besides the other updates, Xiaomi has laid strong emphasis on system security and malware protection with the December 2025 security patch. The update fixes a wide range of vulnerabilities identified at the Android framework and system level. Many of these fixes are rated critical, especially malicious apps capable of locking your device or attempting to access files in a prohibited manner.
In the last few months, some new malware related to Android has been targeting lock screens and input methods. Xiaomi’s December patch directly addresses these risks by strengthening system permissions and improving background process control at the HyperOS level. This helps ensure user data integrity without affecting daily device performance.
Update Availability and System App Security
The rollout is gradual and may therefore take some time to reach all eligible users. When available, update manually using the standard system updater under HyperOS. Xiaomi also recommends keeping system apps up to date, since security fixes often depend on updated core apps.
