You can install Ubuntu Touch on this device using the UBports Installer on your computer.

- Please double-check that your device is a Xiaomi Mi A3 (laurel_sprout). Xiaomi Mi CC9e is NOT supported.
- Your device must be running the stock Android 9 firmware before flashing. If your device is running Android 11 officially, DO NOT ATTEMPT TO ROLLBACK TO ANDROID 9. Doing so will render your device unusable. If your device is running Android 10, download the Android 9 firmware linked below and flash it to your device, then resume the installation.
- If after installing Ubuntu Touch you can't connect to Wi-Fi, pair Bluetooth devices or use cellular data, run the installer again and pick "Reflash dtbo" when you're prompted to select an OS.

Did the maintainer say that feature ‘works’ but you know from doing it that
it really doesn’t?
Start by searching the device issue , if you found it, hopefully the porter is on it. 'Subscribe' to the issue in case it get solved.
Couldn't find it?
Uh-oh… Well it is time to let the porter and everyone else know about the fail and send the tech magic back to the workshop for a makeover.
1. Read 'Bug Reporting' section in UBports docs on 'How to report a bug'.
2. Then (this time), head to the device repository and submit it, so the porter knows about it.
