Samuel Tunick, an activist from Atlanta, faces federal felony charges after using a "duress code" on his Graphene OS phone to wipe its data when questioned by Customs and Border Protection (CBP) agents upon returning from an international trip in early 2025. Tunick, involved with the Defend the Atlanta Forest group opposing the construction of a law enforcement training facility, alleges he was targeted for his activism. His legal team claims he was on a watchlist and CBP had discussed detaining him for "suspected terrorism activities."

During the secondary interrogation, agents claimed they sought evidence of child sexual abuse and threatened to confiscate his phone if he didn't unlock it. Tunick states he was denied legal counsel despite multiple requests. While CBP often seizes phones at the border for later examination, Tunick's Google Pixel was running Graphene OS, a privacy-focused Android variant that includes a duress code feature designed to remotely erase data. The OS is compatible with Pixel 6 and later models.
