HyperOS 4 First Batch: Eligible Devices

Rollout Timeline

Internal testing recruitment closes on October 14. The first batch of stable builds begins on October 15 as the first phase. Based on an earlier official timeline, first-batch devices should get the update before the end of the month, with a second batch planned later this month. Xiaomi has published the full China rollout schedule on its community.

What About Global Users?

A global beta program is running for several devices, but Xiaomi has not announced a date for the global stable release. One reporter expects a schedule soon and a rollout in late October, but that is a guess and not an announcement. Indian users should wait for an official post before making plans.

What Features to Expect

The source article does not describe HyperOS 4 features, and it points to a separate piece on the biggest upgrades. We will add details once Xiaomi shares an official list. Meanwhile, back up your phone before installing any major update, and keep enough free storage for the download. You can read more on the company at Xiaomi and on Wikipedia.

What Is Not Confirmed

The global stable date, the list of eligible devices outside China and the full feature set are not confirmed. The late-October global estimate is speculation.

Quick Answers

When does the rollout start? October 15 in China.

Which phones are first? Xiaomi 17 series, Mix Flip 2 and Redmi K90 series, plus two Pad 8 tablets.

When will it reach India? No date has been announced.

How to Prepare for the Update

Back up photos, chats and important files before you install any major system update. Make sure the phone has at least 30% battery, a stable Wi-Fi connection and enough free storage for the package. If your device is not on the first-batch list, do not worry: the second batch is planned later this month according to the earlier official timeline. Users who joined internal testing should note that recruitment ends on October 14, so there is little time left to apply.

What the Timeline Tells Us

Xiaomi is moving quickly: testing closes on October 14 and stable builds start the next day, which suggests the software is already in a late stage. The company has also published the full China schedule, so owners can check their model. Outside China, the global beta program shows work is under way, but without an official date, any estimate is a guess. The best habit is to check Settings, then About phone, for update notices, and to rely only on Xiaomi’s official announcements for the global stable release. Because the first batch includes the Xiaomi 17 flagships, the Redmi K90 line and two Pad 8 tablets, many of the brand’s most popular current devices are covered.

Readers should keep in mind that early reports can change quickly, so we will refresh this article as official information arrives from the companies involved.
