Man Charged for Triggering Phone 'Duress PIN' During US Border Inspection

A court ruling could decide whether using a device feature that erases data during a warrantless border check counts as criminal obstruction.

Overview

  • Prosecutors have charged Samuel Tunick with destroying potential evidence after he gave a false PIN that activated GrapheneOS’s Duress PIN and wiped his Google Pixel during a secondary inspection at the U.S. border.
  • Tunick’s lawyers say agents repeatedly denied his requests for counsel and never showed a search warrant, and they argue the questioning about child sexual abuse material was a pretext to obtain activist contacts.
  • The government says the January 24, 2025 stop was a routine inspection and does not require a warrant, while defense filings point to a Homeland Security alert sent before Tunick’s arrival to show targeted scrutiny.
  • A judge is set to rule on pretrial motions by October 2026 and the outcome could influence how courts treat privacy tools that can intentionally erase device data and the scope of warrantless border searches.
  • Security experts warn that a prosecution ruling for the government could chill use of privacy-focused operating systems by activists, journalists, and others who rely on features like Duress PIN to protect data.
