The CN announcement is rumored to be scheduled for August 2026.

The exact list will be announced with the operating system. Do not rely on third-party sources based on rumors.

It will be available after a build is released for your device and region, through system settings or our app.

That depends on whether Xiaomi includes it in the update list. As of August 2026, some officially listed devices have not yet received HyperOS 3.

The schedule will be available on our site on announcement day.

The best place to follow the announcement is our Telegram channel.

HyperOS 4 is an unofficial name. The exact version numbering will be confirmed later.

The rollout schedule will appear here on announcement day
