The HyperOS 3.3 testing phase may have come to an end, as Xiaomi has just begun a public rollout to select high-end phones, including the Xiaomi 17 series and Xiaomi 15T Pro, upgrading the OS to Android 17. While it’s technically a major OS upgrade, you should not expect to see visual changes or new features, as we hinted in our past coverage. It lays the groundwork to support advanced features and upgrades coming with HyperOS 4 later this year.

According to the changelog shared by Ximitime, HyperOS 3.3 update mainly focuses on improving system stability and adds the June 2026 security patch. | Device | Codename | Region | Build | Status | Size | |---|---|---|---|---|---|

OS3.0.331.0.XOSMIXM | Mi Pilot release | 7.5GB | Xiaomi is rolling out the HyperOS 3.3 update to the Xiaomi 17 and Xiaomi 17 Ultra in the Global and European regions. It’s being distributed as a public release, while the Xiaomi 15T Pro is receiving the update on the global variant via the Mi Pilot testing channel. That means only a limited number of Xiaomi 15T users will be able to upgrade to the latest build before the wider rollout begins.

Even though HyperOS 3.3 doesn’t introduce many new features or visual upgrades, the download size is massive. That’s because the update includes a new OS, Android 17, which is itself a large package, although major changes are expected to be introduced as part of HyperOS 4. Xiaomi usually rolls out updates in batches, so it can take a few days for the update to appear on your device.

To check for available updates, go to Settings > About phone and tap the HyperOS logo. For the Xiaomi 15T Pro users, the update may take a little longer, as it’s currently rolling out via the Mi Pilot channel. The HyperOS 3.3 rollout has just begun, but Xiaomi is already preparing to release the most anticipated HyperOS 4.

That would be a true major upgrade with major visual upgrades, new features, and enhancements across the system. Xiaomi is expected to release HyperOS 4 in August with the upcoming Xiaomi 18 series, and the rollout to older devices could begin in September. We’ll keep you posted as we receive new details.
