So, I think I was misunderstood here... I only piped up because the GP explicitly said "US" in relation to a failing US based company. Saying that Samsung fills that gap makes no sense, regardless of where the phones are manufactured.

In one sense, you're absolutely right. It's a Korean-owned company and therefore obviously in no way American.

In another sense, the ownership of Samsung is irrelevant. The actual phones have roughly the same level of US-origin content and US-local labor as those phones famously labeled "Designed by Apple in California".
