I have ordered a Shiftphone 8 (https://www.shift.eco/en/shiftphone-8-status-page/), which can easily run non-Google Android to have better privacy, and in addition PostmarketOS looks quite promising (https://wiki.postmarketos.org/index.php?title=SHIFT_SHIFT6mq_(shift-axolotl)&mobileaction=toggle_view_mobile). Shift is working open and closely with the community, so I am really looking forward having a dual boot phone for Android and Linux in the future. 🤪
