I really like the idea of having a physical keyboard on my phone. I’m looking at the pinephone with the keyboard module and it looks pretty cool.
On a related note, are there any accessories that you can attach to an android phone to give it a keyboard?
Use an usbA to UsbC adapter, then you can plug in any old usb keyboard, not practical if you’re planning to bring it with you but i think it’s neat that it just works
Can also add a mouse, or use an usb hub to have both mouse and keyboard

Based on this old stackexchange post it was apparently possible but not trivial, it might be easier to do now but i couldn’t find anything more recent
You could try one of these: https://support.planetcom.co.uk/index.php/Linux_for_Cosmo
But is seems like Ubuntu Touch support was dropped and their own Linux AFAIK never worked very well.
