While the Nokia brand is technically, no longer, it still is used by Microsoft on varying levels. Thus, it’s kind of like a grey-area: everyone knows it’s a Nokia phone, it’s just not a Nokia phone. No matter what you want to call it, the Lumia 830 is a mid-range smartphone running Windows Phone 8.1, and sports a Pureview camera setup.
Does that make it worthwhile? Well, that’s kind of in the grey, too.
