Samsung alerted press that the company would give US Note 7 buyers a trade-in credit of up to $425 on their current phone if they purchased the Galaxy Note 8 on Samsung.com. This is the gesture CNET was hoping Samsung would make to owners of the doomed Note 7 once the Note 8 went on sale.

But if you were burned by the double recall after multiple units overheated and caught fire in 2016, it won't be as easy as raising your hand to get the deal. There are conditions, as there always are. For the most part, the Note 7 trade-in program fits right in to Samsung's existing program for new phones, with just one extra caveat. In fact, the last update to terms and conditions occurred August 14, more than a week before the August 23 Note 8 event.
