Just last week, Google released Android 8.0 Oreo OS to Google Pixel and Nexus devices. Flagship smartphones from Motorola, HTC, Samsung, LG and OnePlus, to name a few are due to get the latest Android update in the coming months. Xiaomi’s flagship smartphones, the Mi 6, Mi 5 and Mi Note 2 among others are likely to get the update too, but the aging Mi 3 and Mi 4 smartphones will be left behind. However, there’s a way you can get Android Oreo on these smartphones right now, here’s how.
Before you get excited, it is important to know that it is not an official update. And to install the ROM on your smartphone, you’ll need a rooted smartphone. A senior developer going by the name Vasishath at XDA-Developer forum has managed to use the Android Oreo source code from Android Open Source Project (AOSP) library, and build a custom ROM for the Xiaomi Mi 3, and the Mi 4.
How to install Android Oreo ROM on Xiaomi Mi 3, Mi 4
Step One: You will need to root your Xiaomi Mi 3 or Mi 4 first. You can head over to this XDA post to look for rooting instructions.

Few things to note
This being an early build, not everything is working. Also, it is not a stable ROM, so avoid installing it on a smartphone that you use as a daily driver. The developer has mentioned that the smartphone boots, camera, Wi-Fi, Bluetooth and sensors work. There may be random reboots and some features may not work, but considering Mi 3 and Mi 4 are old devices, having Android Oreo running on them is something like brownie points.
