    PSA hitting your power button (5)? times in a row (however many it takes to bring up the SOS screen) on an iPhone will disable biometric login until you’ve entered your password again.

    I responded to that with:

    That does not encrypt your storage. It simply disables the biometric authentication methods. Which means they can see your stuff if they get into the phone via a exploit.

    That emergency mode that is activated by hitting the power button 5 times does not encrypt the storage. It merely disables the biometric authentication methods and possibly other things related to security, but it does not encrypt the storage. The phone stays in the AFU state and therefore the decryption keys are still somewhere in the hardware chip’s memory.
