I'm reminded of the scene in "The Return of the King" where Gandalf wraps the palantir in a cloth because he's afraid Sauron might be on the other end. New step one when seizing an iphone: wrap it in something opaque...

New counter to step one: don't allow unlocking the device if no photons are hitting the camera.

Serious answer, small faraday cage bags with velcro+zippers are already sold to law enforcement who need to seize a powered-on phone.

  How have network dead man switches not become popular? "If this phone has had no network access for 4 hours, power off" (assuming encrypted storage).

    You wouldn't even need to power off, just require passcode. You'd also need to require passcode to enter airplane mode. Passcode requirements are pretty opaque though - as is, my Android and iOS devices ask for passcode (vs biometrics) randomly (from my perspective). Would be nice to have proper documentation of all the conditions that force passcode entry.

      >You must enter your passcode or password for additional security validation: - after you restart your iPhone, iPad, or Mac; - when more than 48 hours have passed from the last time you unlocked your device; to add or delete a fingerprint to use with Touch ID; - to change the iPhone or iPad passcode or Mac system password, and for other security settings like FileVault on your Mac; - when there have been more than five unrecognized Touch ID authorization attempts in a row; - after you log out of your Mac. https://support.apple.com/en-us/HT204587 https://support.apple.com/en-us/HT204587 Face ID has the same document: https://support.apple.com/en-us/HT208108 https://support.apple.com/en-us/HT208108

        Cool, thanks. Seems the Android heuristics for requiring passcode entry are fuzzier.
