> Shut down the phone in areas with a high snatch risk.

Yes this is of course safer. What evidence do you have that it doesn't work on GrapheneOS, though?

To add an extra layer of safety. Bring a secondary phone when travelling by airplanes, especially to other countries. You should also use it frequently, maybe with some side apps to make it look like it's your daily phone.

GrapheneOS is critical infrastructure. Questioning it is not like criticizing Neovim. People can get detained, killed and more.

Perhaps the reflexive genius downvoters can explain what happened to Richard Medhurst? After his phone was snatched and the authorities pretended not to be able to decrypt it, he went on a GrapheneOS promotion spree on X and wanted to write a book about computer security.

Now he has disappeared for nearly 6 weeks. How many more people do you want to get in trouble with your false promises?

The internet exists and can transfer your data with no customs and borders, so if you are at risk of being snatched, the correct choice is to not carry a phone (or laptop, or..) at all.
