HyperOS 4 Global Builds Leaked: First Devices and Second Batch

Xiaomi officially introduced HyperOS 4 on August 14, 2026, and development is already moving beyond China. The Xiaomi 17 series, REDMI K90 series, and Xiaomi Pad 8 series have entered the first beta stage in China, while Xiaomi’s servers now show work on Global, EEA, India, Turkey, Russia, Taiwan, and other regional builds. The latest server data also exposes a much larger second batch through new .PRE builds.

The important difference is the build format. Devices with OS4.0.0.x firmware have entered the stable-beta-build preparation stage, while builds using OS4.0.260814.1.x.PRE represent an earlier development branch. For example, Xiaomi 17 already has EEA, Global, and India stable-branch builds alongside its Chinese ROM.

HyperOS 4 Stable Builds Already in Preparation

These devices currently have at least one OS4.0.0.x build on Xiaomi’s servers. These are not public stable releases yet, but they show that Xiaomi has opened the stable firmware branches.

The HyperOS 4 List Can Be Tracked Live

This server list is not static. Xiaomi can add new devices, regions, or newer firmware builds at any time as HyperOS 4 development continues.

The latest status can be checked continuously through the MemeOSUpdates HyperOS 4 Devices tracker. The page tracks Xiaomi, REDMI, and POCO devices and shows their latest detected HyperOS 4 builds and development status.

This is especially useful during the current testing period because a device that only has an OS4.0.260814.1.x.PRE build today may later move to an OS4.0.0.x stable branch without Xiaomi publishing a separate announcement.

The presence of a build should still not be confused with a public rollout. OS4.0.0.x builds show stable firmware preparation, not necessarily an OTA release available to users. Xiaomi’s official Global rollout schedule may also differ from the order in which internal builds appear.
