The new update carries the build number OS3.0.331.0.XOSMIXM and is currently available as a Mi Pilot release.

The update brings Android 17 integration, the June 2026 security patch, and important system stability improvements.

Android 17 Arrives on Xiaomi 15T Pro

The arrival of Android 17 on the Xiaomi 15T Pro is an important step for Xiaomi’s global software strategy. Although this build does not appear to introduce major visual changes, it brings the device to a newer Android base and prepares the system for future HyperOS improvements.

Users should expect better app compatibility, improved framework-level optimization, and enhanced security with this update. However, as this is still a Mi Pilot rollout, some users may need to wait before receiving the update through the standard OTA channel.

Should You Install This Update?

If you are already part of the Mi Pilot program, you can install the update through the system updater. Since this is a major 7.5GB upgrade, it is recommended to back up important data before updating. Users should also make sure their device has enough storage space and battery charge before starting the installation.

For regular users, it may be better to wait for the wider stable rollout. Mi Pilot builds are usually close to stable releases, but they are still distributed first to a limited number of testers to detect possible issues before full deployment.

Xiaomi continues to expand its HyperOS 3 and Android 17 update roadmap across global devices. Xiaomi 15T Pro users can also follow update availability through MemeOSUpdates.com or use the MemeOS Enhancer app to track the latest Xiaomi system updates, app releases, and official firmware packages.
