There is not just iOS and Android - Sailfish OS has been a thing since 2013 and while unforutnately not fully open source, it's perfectly usable (and on my primary smartphone): https://sailfishos.org/

Also, thanks to PinePhone finally providing open yet easily available hardware, there is now a new crop of fully open source mobile Linux distros being developed: https://wiki.pine64.org/index.php/PinePhone_Software_Release...

Sire, not everything might work yet & PinePhone is not at the same level as the latest Android flagship phone (well, you can hardly expect that for $150) but there are multiple people communities of people building new mobile operating systems, right now! Ones that are not controlled by a control freak (Apple) or spymaster dropping services left and right (Google).
