I have a spare Xiaomi Redmi Note 7, 3/32GB version (codename: lavender), which I bought as second hand and which is in very good conditions. I cleared the userdata partition and installed UT on it.
Xiaomi devices are rather popular here in Russia, so if I see that there is interest I might be able to buy more second-hand (or even new) devices and resell them with UT preinstalled. Write me if you are potentially interested. 🙂
You can sell your phone through an ad on the Internet to another person without any problems, even if you only have your charger and phone left.
In Russia, phones are usually already unlocked.
@keneda Thanks, but I finally found it under the cover of what I thought was the m.2 slot. I've got my bluetooth ear buds working using an ancient D-Link dongle which oddly works rather than the Plugable one that's supposedly the best for Linux .
About your device, I'm not sure it is currently supported there are the Xperia XZ and Z1 but those are probably the same.
You can head to https://devices.ubuntu-touch.io/ to see a list of supported devices and their progress.
