Border Patrol can wait longer than you want to wait at the airport, you should not bring your personal phone if you don't want them going through all the contents, they can hold your device for an inconvenient amount of time if you are an American citizen. If you say no and are not an American citizen you can be denied entry at the airport and sent home.
Being quickly denied and sent home is the best possibility in that scenario.
If you're on American soil they can just detain you. Or worse.
If you ever want nightmares, read the story of Maher Arar.
