Xiaomi Begins HyperOS 3.3 Rollout on Android 17 Devices

Your Xiaomi may not look different, but under the hood something significant just shifted. Xiaomi has started a public rollout of HyperOS 3.3 built on Android 17 for select flagship phones, a behind-the-scenes upgrade designed to prepare devices for bigger changes ahead.

Don’t expect flashy new themes or dramatic UI rewrites. This update is engineering-first: stability improvements, the June 2026 security patch, and a full Android 17 foundation that paves the way for HyperOS 4 later this year. Think of it as laying new track before the high-speed train arrives.

Which phones are on the initial list? The Xiaomi 17 series is receiving the update in Global and European channels as a public release. The Xiaomi 15T Pro is included too, but only through the Mi Pilot channel for now, meaning a smaller pool of testers will see the build before the broader rollout.

• Xiaomi 17 Ultra (Nezha) — Global — OS3.0.332.0.XPAMIXM — Public release — 9.5GB
• Xiaomi 17 Ultra (Nezha) — Europe — OS3.0.332.0.XPAEUXM — Public release — 9.5GB
• Xiaomi 17 (Pudding) — Global — OS3.0.332.0.XPCMIXM — Public release — 7.5GB
• Xiaomi 17 (Pudding) — Europe — OS3.0.331.0.XPCEUXM — Public release — 7.5GB
• Xiaomi 15T Pro (Klimt) — Global — OS3.0.331.0.XOSMIXM — Mi Pilot release — 7.5GB

Yes, the downloads are hefty. Why so large? Because Android 17 is bundled in, and a platform-level upgrade takes space even when visible features are minimal. The heavy lift now reduces friction later, when HyperOS 4 rolls out with more visible feature work and interface changes.

Updates will appear in batches, as usual. If you’re impatient, check Settings > About phone and tap the HyperOS logo to force a check. Mi Pilot participants on the 15T Pro should expect a slightly slower, controlled distribution while Xiaomi monitors stability.

What does this mean for users? Better stability and a fresher security baseline today, and the promise of fuller feature updates soon. Industry whispers point to HyperOS 4 debuting alongside the Xiaomi 18 series in August, with wider device rollouts likely beginning in September. That release is expected to be the one that changes the look and feel — the update most people will notice.

Small step now. Bigger leap next. Keep an eye on your update screen.
