But is seems like Ubuntu Touch support was dropped and their own Linux AFAIK never worked very well.
Community about running GNU/Linux on phones. Projects like Ubuntu Touch, Plasma Mobile, PostmarketOS, Mobian etc. Either on former Android phones or hardware like the PinePhone.

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

I used the USB A to C adapter and a USB mouse in order to backup data from a phone with broken touch screen. But simultaneous charge was not possible. Would it possible even to connect the charger to the USB hub at 5V source?
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
