Ludicrous0251FBI Couldn’t Get into WaPo Reporter’s iPhone Because It Had Lockdown Mode Enabled
on Android, you can Press and hold the power button. a menu with 4 options will appear, the top right is the lockdown.
What’s the difference between lockdown and just rebooting your phone (putting it into the first-run state)?
Lock down will do things like disable biometrics, but the phone has still been unlocked and is no longer in a fully encrypted state like it is if powered off.
