Outside Pixel, updates on Android are an embarrassing shit show. I did a three year detour to Android, but never again. Update after update things were broken until and you had to wait 6 months to get an update that was supposedly fixing things.
As someone who considers privacy important, Linux and BSD are the only credible alternatives to the Mac. Unfortunately, a lot of software that I use nearly daily is missing, because the Linux ecosystem does not have a strong ISV ecosystem (Little Snitch, OmniGraffle, Things, DeckSet, LaunchBar, Alfred, Arq, 1Password, Tweetbot, Affinity Designer/Photos, etc.) and does not support some hardware well (Sonos, etc.).
BitWarden is a fantastic FLOSS alternative to 1Password, Emacs’ org-mode for Things is perhaps the finest of its kind and easy to get started with with a distro like Spacemacs, a plethora of Alfred alternatives, Marp for DeckSet, i could go on but at this point i just want to throw up my arms and shake you.
i’ve switched dozens who were sick of proprietary lock-in. it doesn’t sound like you’re sick enough.
However, the open source alternatives for the software I mentioned (and other software) are simply not good enough for me. The additional 'problem' is that open source software that I use, such as Emacs, Latex, compilers, etc. work fine on macOS.
(I used Linux and BSD full-time on the desktop from 1994-2008.)
Stop buying Samsung.
A few years ago I grew so sick and tired of iOS’ arbitrary restrictions compared to Android that I skipped from the iPhone4S to the iPhone6+ with a Google Nexus 5 device, but it was a really hellish experience because I never managed to get things to sync right.
