@Tutanota going further away from the android/AOSP-derivatives: another solution is Linux distributions on smartphones:

- I personally daily drive #SailfishOS for more than a decade (commercially supported versions of SFOS even have "Android App Support" running inside a container for "that one app" with no native linux port you can't get without)

- I've heard positive things about #postmarketOS and #UbuntuTouch (but don't have personal experience)

@stdevel @vincentdettmer Ja ich nutze das seit einigen Jahren nach #WebOS und #UbuntuPhone zuvor war hat man gleich gemerkt, dass #SailfishOS super flüssig daher kam und einen guten Eindruck in der Bedienung macht. Das OS ist also definitiv zu empfehlen. Ob man damit aber als "einziges" Smartphone klar kommt hängt entscheidend davon ab was man von einem Smartphone erwartet. Den Jolla eigenen Browser hab ich mehr oder weniger abgeschrieben.

@lazarus @babababa #sailfishos has slow UI? I've been using it since 2013, but I can't say the UI is slow..

The bad device support situation has one simply cause: every device and mobile SoC platform maker has just one target: Android. They only deliver Android kernel drivers. Test only on Android. Does it work somewhat on Android? Ship it.

Any non-Android-derived platform, even if that platforms runs on generic Linux, is simply ignored. It's not juist SailfishOS which suffers that fate.

@vincentdettmer #SailfishOS wäre noch eine Alternative. Schönes OS und optionaler Android-Emulator. Nur leider über Abo finanziert und sehr beschränkte Hardware-Auswahl.

@annika
That is depressing but I guess I am just moving into that camp too. I must say I did enjoy #SailfishOS while it worked well, as a phone. I always ran it on the only one Sony Xperia model that was supported at the time to have Android app support. There were always occasional bugs but It just got worse after my carrier switched to VoLTE-only, now I'd have to enable “4G calling” to have calls or disable it to send SMS.

edit: It became unsustainable, now I use some other, abusive OS.

@babababa Otherwise there are a bunch of Linux solutions and I probably tested all of them. But they are not quite there.
Most mature is #SailfishOS, but device support is bad, UI is slow and I don't like it.
Then comes #UbuntuTouch, which is missing some driving development - there's no device level data encryption - not suitable for daily use.
There's #PlasmaMobile, didn't test it since a long time - but generally speaking KDE is quite ugly. ;)

@vampiress I've been using #SailfishOS phones since the first one, while using both Android and iPhone on the side.

Functionality is something the user defines. With SFOS I can do all the same weird stuff I'd do with a normal Linux box, so it's very functional. In comparison for me iPhone is highly unfunctional as it is so constrained. But if one's life revolves around various apps, then the case is different.

@vampiress Probably #PostmarketOS and #SailfishOS, for some measure of stable and functional.

Not like Apple and Google are stable and functional either, you just get to choose between which instability and dysfunction you prefer.
