I have really enjoyed using Solus for the last couple of years. Stable yet up to date.

While a valid point this doesn’t really help the OP.

I would recommend the fairphone 4 or 5. I have the 4 and it is great: reparable with software updates (os etc) , easily replaced battery and sustainably sourced.

Fairphone 4

Olnly if you opt out of the new terms, at least in us.IANAL of course

My fairphone4 has been really good so far. If battery power is an issue you could just bring one spare but I haven’t needed to do that yet

I’m currently using OpenBoard with some downloaded language dictionaries. I think it is a good tool, not really able to see definitions though

I’m currently very happy with Solus. Give it a try
