You can buy Nova phones from Huawei, no google inside, pretty good hardware.
You can flash most Sony’s phones with in-house Sony’s Emma tool and get AOSP on them, no google anymore after that.
But in both cases (Huawei’s Emui or Sony’s AOSP) they moslty fork google’s extensive work, namely Android. So you somewhat join that ecosystem.
Or you can use a system as Sailfish, which works great for many use cases, not all.
Allows you to use pure linux apps side by side with (optionally) android ones.
Xperia 10 III is ready if you need to buy ‘now’.
C2 pretty much as well (order here, made in Europe! Jolla shop )
VI and V maybe kind if ready for daily use in a couple of month (if bugs get cleared).
