Judging from the video thumbnail, I’m going to guess this youtuber says no, they aren’t.
Short answer: no.
Long answer: Linux phones aren’t ready in 2025.
Why is half the video some shitty machine generated song?
Nope
Sailfish. (Haven’t watched video)
I don’t this that’s foss but I could be mistaken.
You may be correct. However, the question said “Linux phones”. Sailfish is Linux and it runs on phones.
No love for the FuriLabs project?
Never heard of FuriLabs, looks really cool. How open is the OS/hardware? Could be my next phone… though I’d love to see an immutable approach so I can’t be left with a broken system after an update.
“Are [mainframe OS, non-flagship/consumer OS] [consumer device] ready in [Current Year]?”
Not to be an asshat about it, but this is what the title reads to me. I’d love a Linux mobile distribution, but really what that’s asking for is: optimized mobile driver kit for an open hardware platform, and the ability to manufacture them at an economy of scale to deliver quality without paying out the ass for. I feel like this is difficult because that development time required to have a stable software and the hardware itself would require tons of money, so one would have to be sacrificed since FOSS devs don’t really have a lot of money… since they do it for free.
