In February 2019, Xiaomi launched Mi 9 SE. When launched, the device came with MIUI 10 with Android 9 Pie. In November, Mi 9 SE received MIUI 11 update.
Xiaomi does not follow any kind of pattern for releasing the MIUI global stable ROM update, but on average, the Global Stable ROM is updated every 30 to 45 days.
The update has brought along several features, including new dynamic sound effects, Steps Tracker, a new Mi File Manager app, Wallpaper Carousel, a modern minimalistic design, and even a Floating Calculator.
MIUI 11 rollout by Xiaomi was very challenging to track as of now, because of the complexity in its naming convention of the update and the various upgrades across many regions. In addition to this complexity, there also seems to be a fragile boundary between the builds that are intended only for the Mi Pilot beta testing program. It means that the builds assigned for this group will not be installed on devices with Mi Accounts that do not have the requisite permission.
The same build then again is getting opened up as stable release, generating a lot of confusion. If you get an error message that the update is only for the closed beta testers, you can also sideload the update.
Later in January, Xiaomi Mi 9 SE started receiving MIUI 11 with version V126.96.36.199.QFBCNXM globally.
