I think you’re mixing privacy with security, iPhone is secure but it’s not private, it’s slighty more private than Google Android but not what would you call private.
Samsung can soft brick your phone so basically backdoor.
Google Pixel with custom ROM like GrapheneOS or CalyxOS is considered to be best in terms of privacy.
Another cheaper alternative if you don’t want to give money to Google or spend too much is Motorola G32, G42, G52 with CalyxOS but to unlock bootloader you have to make account on their website.
Can we go 5 minutes without someone proposing a ridicilous law?!
Can’t they focus on problems that actually matter?!
