Xiaomi Auto will open registration for its first batch of HyperOS 1.16.0 beta testers from 10:00 to 23:59 on May 9, on a first-come, first-served basis until all slots are filled. This recruitment is open to owners of the first-generation SU7 (limited to 10,500 participants), YU7 (limited to 10,500 participants), and SU7 Ultra (limited to 3,000 participants). The second-generation SU7 is not included in this beta program, as its system version is still undergoing feature optimization and refinement. Xiaomi cautions that downgrading will not be possible after upgrading to the new version, and users should enroll with caution. Additionally, the beta access granted in this round applies only to this specific update and will not automatically carry over to future versions.
