When will the stable version be released?

The China announcement of HyperOS 4 happened in August, similar to the previous version. Accordingly, we can expect Xiaomi to follow roughly the same release schedule.

The company has not yet confirmed the stable version’s release window, but it is likely that the debut in China is expected around mid-October.

Regarding Global markets and Europe, we expect an official announcement in September and the rollout of the first stable software by the end of October.

The update plan will proceed in phases for all compatible models and will certainly end during the first quarter of 2027 (in line with HyperOS 3’s release strategy). Obviously this is speculation, so we await official confirmation from Xiaomi.
