Same. I was using SailfishOS on Xperia devices and also Ubuntu Touch.

I found SailfishOS UI to be pretty bizarre and for using compiled software (Qt) the UI was oddly laggy. Basic things like attaching photos when sending an MMS were bizarre, you had to do it one at a time from the gallery app, etc.

Ubuntu Touch has a pretty reasonable UI (aside from having a start-bar like thing that you swipe in and out) but they do NOT support VoLTE at the moment which means you can't use it as a phone! Performance on Ubuntu Touch was also pretty bad even on decent hardware and while it's improved on Pixel-era devices you'd think all UI interactions would be instaneous.

Both projects seem to have made some strane prioritizations. Sailfish seems to have pointless re-invented their own UI paradigms, their own browser, etc and Ubuntu Touch doesn't seem to care the devices can't be used as phones given lack of VoLTE but they have Snaps and their own web browser...

I have an Aquaris BQ 4.5 Ubuntu phone and it's my absolute favourite smartphone I've owned (compared to a couple middle market Sony phones, Nexus 5, Nexus 5X, and my current Sony Xperia XA2 Ultra, which is way too friggin ginormous, it's as big as my hand). The dimensions are perfect for me and I really like the Ubuntu Touch OS.

Unfortunately I managed to drop it and now the screen has a dead spot in the bottom left. As that is the spot where the important icons are it means I have a device that works perfectly aside from being entirely useless (a device which resembles its owner perfectly).

Just in case you don't know it, there are several sites still selling Aquaris BQ 4.5 spare parts in Spain, like https://www.repuestosfuentes.es/563-bq-aquaris-45 or https://www.spainsellers.com/repuestos-moviles/bq/bq-aquaris... or https://dakis.es/869-pantalla-tactil--bq-aquaris-4-5-blanca....

I think most sailfish os apps used QML. So not C++?

VoLTE is hard but JMP.chat can act as a workaround.

You're right on the QML ; I'll admit I didn't look super hard, I was under the impression QML eventually compiled down but maybe there's some interpreter-type event loop implementation that results in a slower than expected UI.

Based on this Stackover flow post I guess it CAN be compiled but that depends on the version, open-source, commercial, etc:

JMP.chat exists but honestly that's kind of a crutch or work around if your primary cell phone can't make or receive calls on its own without ANOTHER broker or provider.

One thing I did like about Sailfish OS and to a lesser extent Ubuntu is that it's mostly "standard" Linux under the hood so you can do things like run dnsmasq or something like that and tweak it as needed.

But in this day and age I think the bare minimum for a cell phone is calling, texting (SMS), possibly MMS and GPS/maps that don't need a network or Internet connection. I'm hoping PostmarketOS, Sailfish, Ubuntu Touch, open-source-smart-phone will get there but I'm not holding my breath.

I heard rumours that the new nokia 3310 5g which will be released in may will run sailfish os. Will be interesting to see if it is true, if it will be the same mess that kaios was on the nokia 8000 or if it will actually work well.
