Content ID is automatic and relies on matching fingerprints of existing video. If you upload something that's known to be copyrighted and where the fingerprint is already (or subsequently becomes) known, content ID is what monetises or blocks the video. You don't get copyright strikes for content ID hits, and such a hit is not a "takedown" - that term refers to cases where a copyright holder notifies youtube that a specific video infringes their rights. THAT is when you get a copyright strike.
You have, of course, the ability to appeal - basically saying "Samsung are full of shit, put my video back and tell them to sue me if they don't like it" and that's exactly what happened here.
