Just don’t like the handset itself. I might try getting the 8 pro when they come down in price. I think I’ll be ok leaving Apple, pretty much stopped using Google and Apple apps over the last few years and stopped using iCloud. I’ve mainly switched to using proton. Last thing was to move from iOS to something like grapheneos, which has great control and does everything I need. I’d suggest slowly moving away from Apple ecosystem one thing at a time.
I’ve just started using Linux as well, to hopefully get away from windows in the future. I figure each small step away from Apple, Google etc is a step in the right direction. Good luck
