I just ordered a FairPhone 5 for the purpose of test-driving any reasonable Linux solutions on it. My eventual preference will probably be Mobian or Postmarket OS with plasma-mobile, but those appear to require additional dev time before they're practical daily drivers, especially on the FP5. Ubuntu Touch appears to be a reasonably mature option, and they specifically single out the FairPhone 5 on their website as the best supported hardware right now. I believe this maturity may be largely due to utilizing closed source Android blobs to drive phone hardware which isn't ideal for us FOSS purists but at least has the advantage of accelerating their dev efforts.
I assume this won't become my main phone right away, but I'm curious whether this community believes Ubuntu Touch (or something else) on a FP5 could potentially be a reasonable daily driver by now. A similar post from about year ago answered No, though their question didn't specify which hardware.
Thoughts? Maybe an alternate distro I should at look at for the FP5 specifically?
SMS and phone calling should behave normally on most OSs (if not ready yet then its not a daily driver candidate for me yet). I can't speak to WhatsUp; I strongly recommend something like Signal instead. I know WhatsApp is popular tho, but if they require device integrity there's not much we can do solve that
