What is the most private phone? - Lemmy.World

Rotary.
How? Literally uses the same phone lines that have always been not secure or private
No google, samsung, or apple services in the background or separate carrier operating system. Plus the audio is always worse on the old phones. Unless law enforcement is out to get ya, the only thing being tracked is what time and number called you, or whom you called and at what time.

Seems like a huge oversight in privacy communities, which are frequented by people with state actor level threat models.

Not really. A smartphone with a privacy-respecting OS and E2EE communication apps only is more secure. Though you can argue that it’s not really a phone if you don’t use the soter service.
TL;DR: Out of iPhone, Pixel, Android, AOSP forks, and GrapheneOS, the answer is GrapheneOS by a country mile.

GrapheneOS sometimes sacrifices privacy for security.

I had way more privacy related features and controls on a rooted LineageOS phone (which was obviously much less secure)

I agree with this. However the very latest Pixels (with the stock ROM) might be a bit more invasive than the phones by an OEM like Motorola or Nokia.
