I think privacy is tough so I'm taking it gradually. Just trying to make improvements. With iphone I had the drive, watch, MacBook, apple pay. Pure iphone fan boy.
I now don't use cloud drives, I have a synology NAS drive, use proton as an email service, Fdroid and brave browser, so got out of all the apple, and Google services. I do need it for the play store and maps essentially but that's about it.
With Samsung and Xiaomi, etc they have Google sign-in and their own sign in and terms of conditions. I figured pure Google is better.
It's not perfect but it's an improvement.
