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 China Beta plan is already here. Stable and Global schedules will follow the keynote and official waves.

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

The plans below are official but China-only for now. Global / EEA / RU come later. Device names follow Xiaomi’s public schedule.

The official rollout plan covers China only. Xiaomi hasn’t announced Global or RU dates yet.
