There is a package called android-transfer-file or something like that in the void repos but I’m not sure if its also in the mint repos, might be worth checking, its a gui app that makes it very straightforward to transfer files. Or in last resort you can always git clone the project and use ‘make’ to build manually the app
Linux mint I would say its the one that tends to have better support in a large amount of hardware and it was the first one that I was able to stick with
You can install them like any other package from dnf/apt and then run them with startX (if its X11) or start them via their name if they are Wayland compositors (all this in the tty, the black screen with just letter outputs)
I have been using Wayland on void for a while and have no particular issue with it. There is screen sharing on stuff like zoom that isn’t working at the moment (unless you use gnome) which is a bit annoying but not really serious enough to force a change to xorg. Also Wayland has more clean code then xorg and I do like the potential it has, specially when it comes to security.
Nothing against xorg, if you can use Wayland its better imo but otherwise xorg is fine as well.
Getting rid of WhatsApp is the most challenging part for sure, specially because people at work choose to use this platform. Funny enough, signal is basically the same as WhatsApp and easily accessible on the play store but people refuse to use since they are accustomed to WhatsApp and because the illiteracy on these kind of technologies.
I think its a bit of a overreaction, but you can always download Foss apps even if you can’t download better private OSs, its not the best but its better then nothing
