@simonjust @Gina There are devices out there that are functional without relying on Android. I've been using them as my main phones for the last ~18 years (first Neo Freerunner, then Nokia N900, now Librem 5). Other people are currently using PinePhones, OnePlus 6/6T, Pocophone F1, Pixel 3a and a few others.
Truth be told, for quite a while even with laptops you had to put some effort before going shopping to ensure you'll have a good experience with GNU/Linux.
