eksasol: Mainly I prefer stock Android, but I don't like what Google is doing with their new Pixel phone, which is flagship cost with below flagship hardware, and their privacy invasion has become scarier over the years, although you can't get away from it if you use a smartphone at all.
A month or two ago I was surprised to learn that my brother is actually using a Jolla phone (Sailfish), ie. a non-Android, non-iOS and non-MS phone. He had some idealistic motivations for it.
I was quite interested to try it out, mainly to find out if it would be enough for my needs too. Of course the lack of applications could become a problem, but as long as it has an usable calendar, web browser, and I could get a car navigator similar to MapFactor for it, then I think I would be all set.
Then again I am unsure if Jolla is still a thing or have they died already, I recall reading they've already stopped selling phones/tablets and are concentrating on Sailfish OS itself, or something. Dunno.
I miss my old Nokia Symbian phones (E66 etc.), they pretty much did everything I wanted including offline car navigation and web browsing, and didn't try to invade my privacy in any way. Plus, applications would run only if I told them to run, ie. when I need them. Now on Androids we have something like Facebook which eats your battery alive if you are as much as having merely installed it, and not told it to run. Damn spyware which insists on running all the time in the background, spying on everything you do.
