Also just read that an appeals court upheld the government right to search your phones and retain any data they find despite the 4th Amendment and other privacy protections.

I can't travel anyway because my passport has the wrong gender marker now despite my appearance, genitals, etc. But last time I traveled domestically even, I backed up my phone with the built in GrapheneOS backup as well as some manual backups to a NAS I have at home. Then wipe the phone, install only the basics including not installing my Vaultwarden client which would potentially give them access to all of my passwords, and then restore everything when I get home. It's not perfect and takes a lot of extra work. If I ever get to travel more, next time I upgrade my phone I thought about not trading in the old one and keep that only for travel. Problem is that everything is eSIMs these days, so it's harder to just switch phones out than it used to be. I do wish backups were as easy as they were back when we could root phones without breaking so many apps. Being able to backup the entire partition was so much easier.
