This may be the first time a federal ruling has been made but I don’t know if it applies to state crimes. Many counties across the nation have ruled one way or another.
SCOTUS once ruled law enforcemeny cannot compel you to unlock a device at all and cannot access your phone without a warrant, but I don’t know if that is current. Police can legally lie to you (and beat you with a $5 wrench and pronably get away with it in court).
They also have strong phone cracking packages despite FBI’s lament about evidence locked away in seized devices.
Generally, do not consent to searches or cooperate without a lawyer present. Expect everything an officer tells you is intended to mislead. They will even lie in court to the judge.
