Ya but you can take that one to court. Nothing to do about it if they just put your pinky on the pad

You don’t have to. You use the evidence gathered on the phone to find other evidence that is admissible.

But “going to court” rarely happens. 95% of cases are plea-bargained.

Given overwhelmingly evidence and an overworked public defenders office, you’re not going to take a chance on going to court where you will probably lose.
