My original plan was to jump to a Linux phone (PinePhone Pro), but that hasn't really worked out software wise. FuriLab's FLX1 seems to hold some promise regarding Linux, but they're having trouble shipping. HMD has some offerings with the right features, but software support is lacking. So my current plan is to stick with my FP3 until it becomes unusable.

I love FairPhone's vision, and I think they do a pretty good job executing it. There's certainly room for improvement, but I've been really happy with my purchase. I also think removing the headphone jack was a direct betrayal of their ideals.
