I'm wondering what impact (if any) this has on a years-ago SCOTUS ruling? You can be compelled to unlock your phone without a warrant if it's only secured with a biometric lock (fingerprint/face) but not if it's a PIN or pattern - that requires a warrant.
I've made a point of power-cycling my phone when going through Customs since then, because my phone requires both after a power cycle.
@ScottSoCal on an iPhone you can also tap the power button five times to require the pin to unlock
@ScottSoCal well SCOTUS hasn't actually ruled on compelled unlocking yet. There are definite tests that courts have applied in recent years, but it's all under Fifth Amendment case law and deals with the aspect of self-incrimination
@ScottSoCal @zackwhittaker Iβve switched to always requiring a pin.
