No, they didn't. What Samsung did was release software that mimicked facial recognition. In fact, it mimicked it so well, people were convinced that Samsung did it first. What Samsung actually did was implement software that would sometimes coincidentally "recognize" a face, and more often would "recognize" a photo of the target user. What Samsung didn't do was implement facial recognition that was reliable and secure, which I think is what most people think of when they think "facial recognition".
