Few weeks ago I saw a really cool presentation about the history and current state of Linux phone. It is unfortunately in German, slides in English though: https://youtu.be/JeFoRE72Gu0

List of all Linux phones https://linmob.net/resources/#smartphones

I put PostmarketOS on a spare device recently. PostmarketOS describes itself as currently being in a state suitable for Linux enthusiasts to try out, not for wider use. That seems about right to me.

On the fun side, it's proper desktop-style Linux. I can SSH to it from my laptop. I can compile software on it. I can run programs that have no business running on a phone. On the not so fun side, the cameras barely work, data over USB doesn't work at all, and battery life is not good. Desktop Firefox on a phone screen is pretty bad. Rumor has it there's some support for Android apps, but I've been looking at Waydroid's splash screen for a long time now with no progress.

not yet

PostmarketOS makes no claim that it is ready to be a daily driver, Linux phones are pretty experimental right now. That's why there is so much tension over the custom ROMs that manage to function on such locked-down hardware

ubports was pretty good last I tried but there were basically no apps. that was on xenial so it may be a bit better now especially with waydroid.

I wouldn't consider any Linux phone ecosystem developed enough to consider a "daily driver" phone yet. If you need a phone to be functional at pretty much all times as a phone, but you don't want to give into smartphones, I honestly would suggest a VOIP landline (that you potentially roll out and serve yourself, depending on your level of technical ability and available resources).

They all have issues. The OS portion is just ramping up again brought on by the Google coup on Android.

Honestly, you'd be better off getting something that runs a better Android OS for now versus running a Linux derivative.

The main issues:

• Camera sensor support and control
• Modem (phone) stability
• Sensor support
• Biometric sensor support
• Specialized hardware support

No.

The closest to a daily driver you can get to is Sailfish OS on a supported phone. There's a lot if amazing work in the linux phone space as the bar for daily driver is fairly high.

I daily drive Ubuntu touch and like it very much, but I can see how that would be hard in certain situations. Keep doing some research, and pick one that seems to fit your needs to try it out! Only you can decide if it is good enough for your particular circumstances.

If you're coming from a feature phone - it's great!

If you're coming from a modern smartphone, you probably won't be happy with it as a daily driver.

I'm voting with my feet, but carrying two devices.

I had a pine phone for a while and it was sufficiently developed to use it as a daily driver… if you could put up with dropped calls, and texts, and burning thru ur whole battery in one hour cuz sleep didn’t work.
