Pine phone Junior, message phone ?

[wibble]

A lot of the cheap ones are using KaiOS now so perhaps too googley for you.

I recently found there's a GerdaOS when reading here (Tor required to access), which runs on exactly 5 phones according to that article.
Can be found on: https://gerda.tech/ (no Tor required)

Thanks - hadn't spotted that one. Unfortunately it seems abandoned - https://gitlab.com/project-pris/system hasn't seen any commits in a year.
