A bit late to the party here, but today I flashed Ubuntu Touch onto a Xiaomi Poco X3, and it’s… well, it’s rough.

All the base functionality seems to be there, calls should work (not sure because I didn’t test them extensively), sms works, location/gps works, nfc is supported, camera is… passable, battery life is certainly, and noticeably worse but that’s a given - when on standby, the battery goes down roughly 8% every 5 hours, so approx. 27% per day on standby.

While I’m really glad to see how much Linux phone development sped up, they are still nowhere near daily driver status - even the phones built with Linux support in mind are not faring well from what I’ve seen. Even then, I’m keeping this Poco X3 because Android’s days seem to be numbered.
