Or just restart your iPhone.

I've heard more than one person say if you're going to have to surrender your phone, if there's even the risk of it, turn it off.

  If you turn off your iPhone, you can't use it again without entering your password, and you would have to do that consciously. On the other hand, your phone could otherwise be unlocked with just your fingerprint.

    Is there a way to know Touch ID is available, but can't be used because the device was just rebooted? Or does it act like there's just a password?

        "iPhone requires your passcode after restarting" vs "Touch ID requires your passcode when iPhone restarts" Also, if Touch ID is disabled then putting a finger on the sensor does nothing, but if it's enabled it shows the passcode screen with the above message Edit: with Touch ID enabled, if you slide to the lock screen without touching the sensor, it says "iPhone requires your passcode after restarting" but the title says "Touch ID or Enter Passcode"

  At the very least, use the wrong finger 5 times on the sensor and it will disable the Touch ID.

    And risk being charged with obstruction. Like perjury, it's naturally difficult to prove, but one should be aware of the risks before moving down that course.

      No, I mean, disable Touch ID before any potential situation where the phone might be seized for any reason, not after a judge had ordered you to unlock the phone with a thumbprint.
      - jdmichal 10y ago
        The moment you believe the phone is going to be seized by law enforcement and you act accordingly to make it more difficult or impossible to retrieve data from it, you are guilty of spoliation / tampering of evidence. This is the same set of laws that makes it illegal to shred papers before law enforcement can get to them. Locking or erasing your phone is simply the digital equivalent.

        "I just turned it off since the battery wears down really quickly and I thought I might need it to make a call later." Difficult to prove.

        Difficult to prove and illegal. Like lots of things.

Correct that you cannot be compelled to unlock your phone (with a code, not Touch ID) or reveal the passcode?
