The Second Circuit Court of Appeals ruled in United States v. Alisigwe that border agents may search a cell phone at the international border with no warrant and no reasonable suspicion.[^2]

The ruling covers cell phone searches at the international border. It appears to give agents the authority to inspect a phone without stating a suspicion first.
