Steps to Install Android 10/Android Q on Mi A2
Since the device has an A/B Partition scheme, flashing ROMs, Recoveries and Magisk take a slightly different approach. Do follow the points as mentioned in this guide, otherwise, you will brick your device.

Final Thoughts
Congratulations! You have just installed the Android 10/Android Q on your Xiaomi Mi A2. Do note that the ROM is currently in the alpha stage, not even in the beta! So expect it to be less stable. And although I tried it on my device and didn’t found any bugs as such, yet the performance may vary from device to device. I wouldn’t recommend you to use it as a daily driver. Also, there may be compatibility issues with some of the less popular apps. This is because not all the apps have been made compatible with the latest API version. With this, we come to the end of the guide on how to install Android 10/Android Q on Mi A2. If you have any queries, do let me know in the comments section below.
