Xiaomi published the official China rollout plan: October 15, 2026 through January 2027, in waves by model. Global and RU dates aren’t announced yet.

Early waves cover Xiaomi 17 / 15 lines, REDMI K90 / K80 / K100, and several tablets — full list on this page. The Global list will be separate.

Only China Beta is open for now. Global builds will arrive after a release for your region, via system settings or our app.

For China Beta, check the waves above. For Global, it depends on whether Xiaomi includes the model in the official update list.

The official CN stable plan is already on this page (waves 1–6). We’ll add Global and EEA/RU when Xiaomi publishes them.

We’re on the beta and share detailed coverage in the Otreepro Telegram channel.

The list above is Xiaomi’s official stable HyperOS 4 plan for China only. Global / EEA / RU come later. Device names follow Xiaomi’s public schedule.
