I have been looking for recent news on pinephone support but couldn’t find anything more recent than this post, /e/ for PinePhone Brave Heart Edition? - #27 by Manoj, dated from July 2020.
As far as I followed, at first the problem was that it was an exclusive linux phone without android port but now, for a year, glodroid exist on Pinephone (first android 10 and now even android 11) : GloDroid (Android-11)
Will /e/ OS come to the PInephone?
Best regards to all /e/ devs,
