I looked into buying one a while back, and the spec sheet said it was using a 9 year old processor, and PinePhone uses a 13 year old processor.
It wasn't "discontinued," no one was working on it for years, and it was pointless to purchase.
The PinePhone is an outdated ripoff.
"No one was working on it for year" is both untrue and unfair. There have been continued improvements (both PinePhone and PinePhone Pro), and I know that there are people who have put in the midnight oil to make them happen.
What that work was not is 'paid for by PINE64'. It's also not been enough to raise the bar enough to make the phone work well enough; but if you consider what's involved there, it makes sense.
You don't just need to write/fix a driver, you need upstream (or at least a distribution) to accept it and include it for that work to make a meaningful difference for anyone else.
The best way to experience #LinuxMobile is IMHO on former Android Devices like the OnePlus 6 or Pixel 3a, as these are well designed devices with SoCs intended for phones. While having native hardware would be great, it's really hard to produce relatively bug-free hardware from scratch. With mainline, the SoC is always going to be older, and small-scale production leads to high prices. The economics just don't work out for non-enthusiasts who then ideally are also up for paying a software support subscription. Also, as a manufacturer you'll want to somewhat control the experience, leading to 'yet another small scale device-specific distribution, which has it's downsides.
Across devices audio issues are unfortunately still somewhat common, in part caused by the Pipewire transition (things that had been figured out for PulseAudio need to be figured out again). But it's on people's radar, and funds are invested to solve this [2].
VoLTE is another challenge, as it allows to carriers to become more gatekeepy with their stupid device support lists - of course there are workarounds like using a SIP account, but that's too inconvenient for many. Also, RCS support is not yet there, but as long as SMS/MMS fallbacks are still around, this not a dealbreaker.
