It was more like making the PinePhone catch up to Librem 5. I'm writing this on my L5 and I still have no prospects if I wanted to upgrade.
Guess I thought of that one as more like a "fix," since the first one was not fit for purpose. Still not good enough, needs spec bump and driver support.
I was looking at potential linux phones the other day, postmarketOS has ports for phones as new as fairphone 4 and OnePlus 6. They don't have any phones with decent camera support though.
