giftdetect· the right gift in minutesXiaomi has begun rolling out HyperOS 4 in China, but a number of older phones, including the Xiaomi 12T and Redmi Note 12, will not receive it. The update started reaching the company's newest phones and tablets on October 15, 2026, and those models are already at or near the end of their software support.
Who gets it, and when
According to Xiaomi's rollout schedule, the first batch covers the Xiaomi 17 series, the Redmi K100 and K90 series and the Xiaomi Pad 8. In total, the plan lists 57 phones and 15 tablets. The Xiaomi 15 series, MIX Flip 2, Civi 5 Pro and Redmi K80 series were due by November 15, the Redmi Note 17 and Note 15 lines by November 30, and a large December batch includes the Xiaomi 14 and 13 series and Redmi K70 series. January 2027 is reserved for TVs and wearables.
Phones whose support ended this year, such as the Xiaomi 12 and 12T, are missing. Firmware trackers also say six cheaper models have not entered testing: the Redmi Note 13 Pro 4G, Redmi Note 14S, Redmi A5 4G, Poco C71, Poco M6 Pro 4G and Poco X6 5G. Xiaomi has not confirmed their exclusion. The Xiaomi 13 series is on the December list, though it is unclear whether it gets Android 17 or a build on Android 16.
What is new
The update introduces Soft Light Glass, a translucent design that Xiaomi says adjusts its transparency to the content behind it, and a lock screen clock that can be resized, moved and restyled. The full effect requires a Snapdragon 8 Elite, Dimensity 9500 or XRING O1 chip or newer; older phones get a simplified version.
Xiaomi also claims 27.2 percent more free memory after eight hours of use and 17.5 percent faster app launches after long sessions. The Super XiaoAI 2.0 assistant now runs on the in-house MiMo model and offers an Expert Mode for multi-step tasks across apps, though most AI features remain China-only.
Global release unclear
A global beta opened in September 2026 for several flagships, but Xiaomi has given no release date for global markets or India. Poco phones, which are not sold in China, are absent from the schedule. Xiaomi's support promises have lengthened, with the Xiaomi 15 getting four OS updates and six years of security patches, still short of the seven years offered by Samsung and Google.
