Did phone manufacturer finally decide to keep supporting their models after the first year/couple of years? Or did the “likely lifetime” of a smartphone dropped below that in the meantime?

If anything, my experience with “manufacturer support” on android isn’t particularly stellar, with the only outlier being my current Samsung XCover, which is kinda cheating due to the thing being a rugged phone targeting companies and not the average joe, so the thing is built to last, both hardware and software side.

On the other hand you do have a couple (maybe even three!) companies that offer linux pre-installed on their machines.

Desktop crashes, oh there goes all my applikations that I started, gnome can’t keep up with switching workspaces[…]

GNOME, found your problem.

I can take screenshots or rebind keys on KDE, all of that without session losing crashes.

All you are describing simply doesn’t happen in KDE, and GNOME is notoriously bad at handling crashes, so go complain about GNOME rather than wayland as wayland is clearly not the culprit.

Don’t forget to label the label machine, just in case.

Sure, buy american hardware to flash an operating system based on an american operating system made by an american mega-corp. (yes, graphene OS only works on google pixels afaik) You understood the assignment perfectly on this european community, congrats.
