In defense of Graphene for the first point:

Graphene has a pin scrambler, so the numbers are in a different position everytime you have to enter them.

It isn’t hard at all to get used to it, and it circumvents the pattern recognition bit.

Fingerprint unlock…that’s a different discussion especially with biometrics not being protected under the law, but for first unlock you always have to enter in a pin

Quickly looking at my phone, you can enter in a passphrase (though personally I think that’s too cumbersome). There’s also a swipe option, I THINK that might be pattern, but I’m not sure. I can’t test it, because it means deleting the already in place measures, and I don’t wnat to do that at the moment.

I don’t know enough about other points to comment on it.

Can you expand on that? That’s a really interesting conclusion and I’d be interested in hearing how that would work.

Personally I use that setup and am quite disappointed to hear that using wifi calling isn’t the best idea.

May I should just have wifi calling off the entire time, but I would appreciate an explanation so I can plan on how to tailor my phone usage next.

Thanks

Even if you’re using a VPN?

I have a question about methods 1 & 2: do you know if having your phone in wifi calling mode with airplane mode on, prevents that form of tracking?
