Reverse Engineering iOS 18 Inactivity Reboot

To me the biggest takeaway is that Apple is sufficiently paranoid to add this feature. Some people (like John Gruber) advocate for activating bio lockout at the border by squeezing the volume and power buttons. I would say if you’re the type of person who would do this, you should go one step further and power off.

Similarly, if you’re in a situation where you cannot guarantee your phone’s security because it’s leaving your possession, and you’re sufficiently worried, again, power off fully.

I'd travel with a different device, honestly. I can get a new-in-box android device for under £60 from a shop, travel with that, set it up properly on the other side, and then either leave it behind or wipe it again.

The £60 burner sounds like a leader on the device security front. No way it could possibly be running an ancient version of android that is no longer getting security patches, or is hacked up to shit by the device manufacture to reskin it and install their vulnerable suite of bloatware, or built off of a base os and firmware flocked to by folks for its ease of being able to gain root access/root it and run whatever you want at the kernel level.

It could be doing all that actually but you are not obliged to install all your apps on the burner, just the basic minimum.

You're still walking around with a microphone and gps tracker connected to a cellular network even if the only thing you do is power it on

If that's your threat model, don't carry ANY phone. Probably best not to carry any modern electronic device at all.

Real criminals who don't want to be caught don't carry phones for this exact reason.
