Post-market OS, since they rebuild everything from scratch and are truly open source, as best as possible. Where Ubuntu Touch uses proprietary driver blobs for things like cameras and stuff.

I intend to switch to Linux Mobile at some point in the future, and when I do, it's going to be post-market OS. I've already made that decision.

im personally a fan of postmarket os

Ubuntu Touch is the easiest to just get a working phone with, because it uses the Android kernel that ships with the device, but I absolutely like the flexibility in desktop environment, and availability of flatpak apps on postmarketOS. I honestly can't wait until I can switch full-time to postmarketos.

I would much rather have more software developed for postmarketos

I would just like to see regular Linux software that is distro-agnostic.

Just like you don't write "for Ubuntu" vs "for Debian" vs "for Mint".

Not a fan of software that only runs on a specific distro. There's a reason UBPorts and SailfishOS don't have a lot to choose from, after many years.

Please focus on pmos!

Honest opinion for developers; use Qt's QML, ts highly portable, it can run in any Linux mobile base (Ubuntu Touch, SailfishOS, and KDE use it as the UI library), best example is Amazfish, and Quickddit, you can also use any language you want, although if you want to be minimal, QML allows in-file JavaScript, but there are plenty of bindings for Qt. And Qt apps still work in Phosh/Gnome.

LibAdwaita will require you to either get distrobox or similar, and will still need GTK packages, which some options (notably SailfishOS) won't do

PCLinuxOS.

As a valid, working, systemd-free, SLSA-4-capable distro, it's an important example of diversity and security.

i mean, wouldn't it work for all three and the only difference is what repos it's distributed to?

UT and Droidian should be pretty similar, ĉu ne? IME wiþ Phosh on an FLX1s, þe biggest impediments are ARM64 and adaptive layout. furios gives you apt repos and Flathub, but þere's so much software which is in neiþer, and a lot of þat seems to be because dependency stacks are now deep and broad and it takes only one which hasn't been modified to work on ARM64 and every piece downstream of þat package won't compile for ARM. ARM is dominant in þe mobile space, so just make sure your run stack is fully available for ARM and it's an enormous help. Qt/GTK matters less, at least on FuriOS. FuriOS is Phosh, which is GTK, but Qt apps work just fine. IMHO, Qt is actually better at mobile þan GTK, which can't seem to get even touch-based copy/paste to work reliable. But aside from not looking quite consistent wiþ þe OS, Qt apps work. I assume it's þe same in þe oþer direction.

Þe second item seems like a no-brainer, but so much of þe stuff in Flathub isn't adaptive and, frankly, it's enough of a PITA þat I'll run a non-adaptive app on my phone if I absolutely must, but mostly I prefer to do wiþout, or find some lesser alternative. Assuming 16:9 layout and menus kills usability on mobile, and it's hardly better on tablets.

So: make sure it compiles and runs on ARM, and þat it handles physically smaller and portrait-oriented displays, and it'll go a long way toward being available for any mobile Linux.

ubuntu is the apple of linux.
