The HyperOS 4 rollout is now live in China. Xiaomi began pushing the stable build, based on Android 17, on October 15, 2026, and it is reaching phones in waves rather than all at once. If you own a Xiaomi 17 or Redmi K100 phone in China, you are first in line; everyone else is waiting.
- Stable rollout began October 15, 2026, in China only.
- Built on Android 17, with a glass-style look and new AI features.
- First waves cover the Xiaomi 17 and 15 series, Redmi K100 and K90 phones, and the Pad 8 tablets.
- No official global stable date yet; a global beta is running.
Those are the facts Xiaomi has confirmed. Anything about global timing is still an estimate, and I’ll flag it as one below.
What the HyperOS 4 rollout actually covers
Xiaomi unveiled the software on August 13 and opened the beta the next day. The beta ended on October 14, and the stable release started right after, according to Teltarif.
The company calls its dates “guideline values.” That means two phones with the same name can get the update at different times in different regions. Don’t treat any date as a promise.
Which Xiaomi phones get it first
Teltarif lists the first two waves as the Xiaomi 17 series, Xiaomi 17T, the Xiaomi 15 series, and Redmi K100 Pro Max, K100 Pro, K90 Pro Max and K90. The Xiaomi Pad 8 Pro, Pad 8 and Redmi K Pad 2 are on the list too.
Gizchina’s summary of the first wave is a little narrower and focuses on the Xiaomi 17 line, the Redmi K100 and K90 phones, and the Pad 8 tablets. Both agree on the core group. Check the Xiaomi Community app for your exact model.
Some devices were already getting builds before the official date. Since September 17, a few Redmi K-series phones, the MIX Flip 2 and some Pad models have received updates progressively, per Teltarif.
What changes in Xiaomi HyperOS 4
The headline change is a “Soft Light Glass” design, with glass-like surfaces and lighting effects. Xiaomi also points to more home screen customization, faster app loading and more AI features, Notebookcheck reported during the beta.
Camera and video get attention too. The beta notes mention better HDR processing, a more responsive camera app and improved video playback.
The pattern is China first, then a slow spread to other regions. That is why global users should expect a wait.
One tester says phones run cooler and apps stay in memory longer. That is a single anecdotal report, not a benchmark, so wait for wider feedback before expecting a speed boost.
When will the HyperOS 4 rollout reach global phones?
| Region | Status | What to expect |
|---|---|---|
| China | Stable rollout started Oct 15, 2026 | Phased waves, with the roadmap running to January 2027 |
| Global | Beta only | No official stable date; one report guesses 4-6 weeks after China |
| Older models | Last in line | Xiaomi says older phones get the update at the end of the schedule |
Xiaomi has not published a global stable date. A global beta already runs on the Xiaomi 17, 17 Ultra, 17T, 17T Pro, 15 and 15 Ultra. Teltarif guesses a global stable release four to six weeks after China, based on past releases. That is an estimate, not a Xiaomi promise.

How to get ready for the update
Do a few simple things before the notification arrives. They take ten minutes and save headaches.
- Back up photos, chats and app data to the cloud or a PC.
- Charge the phone above 50% and free up at least 5GB of storage.
- Open Settings, then About phone, then System update to check manually.
Also update your important apps first. Banking and work apps sometimes lag behind a new Android version, and a fresh app build avoids login problems after the switch.
Early stable builds can have bugs. If your phone is your only work device, waiting a week for the first fixes is a fair choice.
Frequently Asked Questions
Is HyperOS 4 based on Android 17?
Yes. Xiaomi built HyperOS 4 on Android 17, and the stable version began rolling out in China on October 15, 2026.
When does HyperOS 4 come to global Xiaomi phones?
There is no official date. A global beta is running, and one report estimates a stable release several weeks after China.
Can I go back to the old version after updating?
Not easily. Xiaomi warned during the beta that you can’t roll back over the air, and a clean flash may be needed.
Will my older Xiaomi phone get HyperOS 4?
Possibly, but later. Teltarif says the roadmap runs until January 2027, with older models last.
What this means for non-Chinese buyers
The China launch is a preview of what is coming, not a reason to import a phone or flash a Chinese ROM. Global firmware often differs in apps, services and languages.

Our take
If you are in China on a flagship, update once the notification appears and you have a backup. Everyone else should stay patient: global builds are still in beta, and the first stable release of any big skin tends to need a patch or two. Don’t flash unofficial files to jump the queue.
