Xiaomi's new HyperOS 4 is rolling out in China, but phones like the Xiaomi 12T and Redmi Note 12 are left out because their support has ended.
Xiaomi has started rolling out HyperOS 4, the new version of the software that runs its phones, and some older models will not get it. Owners of the Xiaomi 12T and Redmi Note 12 are among them. Both phones are at, or near, the end of Xiaomi's software support. The rollout began in China on October 15, 2026.
The first batch covers the Xiaomi 17 series, the Redmi K100 and K90 series and the Xiaomi Pad 8. Xiaomi's schedule lists 57 phones and 15 tablets in total, with more waves running through January 2027. December is the biggest month and includes the Xiaomi 14 and 13 series. January is reserved for TVs and wearables.
Once a phone reaches its end-of-support date, it stops getting new Android versions and security patches. Patches are small fixes that close holes attackers could use, so an unpatched phone is easier to break into. Xiaomi publishes these dates on its security center site. Gizmochina counted 19 devices dropping off in 2026.
Some cheaper phones still inside their support window may also miss out. Ximitime, which tracks Xiaomi firmware, found no test builds for six models, including the Redmi Note 14S and Poco X6 5G. Xiaomi has not confirmed they are excluded. If they are, they stay on HyperOS 3.
HyperOS 4 brings a see-through look called Soft Light Glass, which has drawn comparisons to Apple's Liquid Glass. The lock screen clock can be resized, moved and restyled. The full effect needs a recent chip, such as the Snapdragon 8 Elite or Dimensity 9500. Older phones on the list get a simpler version. Xiaomi also claims 27.2 percent more free memory after eight hours of use and apps that open 17.5 percent faster after long sessions. Most of its new AI features are China only for now.
Look up your model's end-of-support date on Xiaomi's security center site. For context, the Xiaomi 15 is promised four OS updates and six years of security patches. Samsung and Google now offer seven years on their flagship phones. The Xiaomi 13 is also in its last year of promised security patches.
Outside China, the picture is unclear. A global beta opened in September 2026 for the Xiaomi 17, 17 Ultra and Leica Leitzphone, then the 17T, 17T Pro, 15 and 15 Ultra. Xiaomi has not given a global release date. As of October 11, Beebom reported no timeline for India or other markets. Poco phones are not on the schedule at all. It is also unclear whether the Xiaomi 13 gets Android 17 or a version built on Android 16.
Check your Xiaomi phone's end-of-support date, because once patches stop, the phone becomes easier to attack.
