May I ask why? I was about to look into the project and potentially purchase one.
That said, go ahead and get one. They're cheap enough that they are fun toys, and it's a way to vote with some dollars. Even tho it's not ready for daily driving, I think it will be in a few months, or sooner given how fast things are moving in the community now that there's real hardware people can buy. You can help with development by reporting bugs and such. Also you get to be a part of history!
It sounds like the most important issues (i.e. battery life/suspend, camera support etc.) is getting resolved fairly quickly while sanding down the rough edges on the UI will probably take time. So it's usable, just not rock solid or feature complete from a software standpoint.
And oh yeah, I'm totally planning to buy a PinePhone because because it's cool as hell.
I still have to measure it a bit and play with it more. I've made a fake battery recently to measure power consumption in suspend independently: https://megous.com/dl/tmp/IMG_0047.JPG
So I'd say it can be used as a daily driver, unless you have strict requirements on app compatibility.
Speaking of which, I wonder how an emulated Android device (or even a real one) streaming video on my pinephone trough LTE would fare :)
Yeah, I keep meaning to glue together scrcpy+xvfb+x11vnc+guacamole when I get the time and motivation. Should be fun:)
Even with that, most of them do not have a lot of basic features of what a vanilla smartphone would have either.
That isn't to say it will stay that way. I try out a few of the OSes about once a month or so, and the difference from when I first got it to now is astounding. I think (hope) that by the end of the year that I can use a Pinephone as my daily driver.
If security (which is necessary for ensuring privacy) is of value to you, get a Pixel 3a, possibly with GrapheneOS.
Get both to support free software, the idea of free hardware, but don't compromise your phone security model just yet.
A64 can do secure boot, I'm sure. So if anyone will have interest in implementing it and locking down their device, it's possible.
Personally, it seems like too much trouble, for little benefit at this point in time.
And upon reboot, a proper verified boot, as well as Auditor &or Attestation, lets you know, with cryptographic proof, whether your phone's firmware has been compromised by such a piece of hardware.
The PinePhone has a lot of potential IMHO. It's nowhere near ready to be your primary phone, but it's neat and at $150 it's a fun little toy.
IME, Fedora worked the best out of the box. I had issues with the battery not being recognized by postmarketOS (along with a few other things) though from what I've heard from others in chat rooms that's atypical (usually pmOS works great).
I'm super impressed with the PinePhone hardware wise. It looks and feels like a decent phone, and it's easy to remove the back and tinker or flip the hardware switches. You can tell they put a lot of thought and attention to getting it right. My only hope is that once things are working, I can buy one with specs comparable to the OnePlus 8 Pro (with similar price tag of course).
