Just like some other smartphone OEMs, Xiaomi also becomes quite active and fast enough in terms of providing firmware updates to its devices this year. After releasing the MIUI 11 update for the Mi 9 model, this is the third update that arrives in China with a software version V188.8.131.52.QFACNXM based on Android 9 Pie. The new update brings bug fixes and improvements. If you’re already using the MIUI 184.108.40.206 version on your Mi 9, then check this guide. Now, you can download MIUI 220.127.116.11 China Stable ROM for Mi 9 from here.
The new software update offers the November 2019 Android Security Patch level to the device that fixes a major vulnerability in the System Component that could harm the system and data on Android devices. It also brings improved system stability for enhanced user experience. The Mi 9 (Codenamed as cepheus) Chinese variant users will soon receive the OTA update. Meanwhile, you can check for OTA updates or manually install the firmware as well.
Check OTA Update
The firmware is rolling over-the-air via gradual mode. Therefore, some of the users may not get the OTA update at the same time. Either you can wait for the OTA notification or manually check for it.
Ensure that your phone is connected to a Wi-Fi network and should have at least 50% battery level.
Next, head over to the device Settings menu > About Phone > Software update > Check for update. Additionally, you can directly go to the Software Updater app to check OTA as well. If the latest V18.104.22.168.QFACNXM update is available, just download and install it.
