FYI GrapheneOS is not vulnerable to cellebrite unlock attacks.

This is a conversation for another time, but this is why I have no useful information on any devices that aren't bolted to the ground behind a cage and key. Gonna have to go get a warrant fed boi. I can only access my data over authenticated network connections. Pictures, contacts, passwords, you name it. It's a ripe pain in the ass, but it's the best way I can think of. Theirs nothing to take if it doesn't exist.
I also refuse to purchase a Google device with Google black box drivers, regardless of the OS running on top of it.
