> In law enforcement scenarios, a lot of the forensically relevant data is available in the AFU state. Law enforcement takes advantage of this and often keeps seized iPhones powered on, but isolated from the Internet, until they can extract data.

In Slovenia, devices have to be turned off the moment they are seized by their owner, prior to putting them into airplane mode.

Also when thieves or muggers rob someone, the first thing they do is turn on Airplane Mode or force power-off.

WHY the hell don't those actions require a passcode or bio authentication??

You can definitely block AirPlane mode without a passcode on iOS. I disabled the access to the control center when the iPhone is locked. Therefore thieves won’t be able to do so.

This doesn't work if they steal it out your hand while it's unlocked.

Slight mitigation to this is you can add an automation via the Shortcuts app to be triggered when airplane mode is enabled, and set the actions to immediately lock your device and disable airplane mode

Downside is that you need to manually disable the automation if you actually wish to use airplane mode (and also remember to re-enable it when done)

I assume apple has something similar to https://support.google.com/android/answer/15146908

Theft Detection Lock uses AI, your device's motion sensors, Wi-Fi and Bluetooth to detect if someone unexpectedly takes your device and runs away. If Theft Detection Lock detects that your device is taken from you, it automatically locks your device's screen to protect its content.

I've set two automations: 1) When airplane mode is activated, lock the screen. 2) When airplane mode is activated, turn it back off. That'll give me the most opportunity to either track it and/or lock it down remotely.

I can remember to disable the shortcut whenever I fly and need to enable it.

If they pop my SIM (my provider doesn't use eSIMs...) then there's a PIN on it to prevent use in another device.
