SEOUL, South Korea (AP) — Hundreds of South Korean Galaxy Note 7 smartphone owners were preparing Monday to file a lawsuit against Samsung Electronics over the fire-prone device. Attorney Peter Young-Yeel Ko, head of the Harvest Law Firm said Monday that 527 consumers want Samsung to compensate them for the costs to visit shops to exchange their phones, for the hours they had to wait while transferring data and for psychological harm from using a hazardous product. Apparently in response to criticism over its handling of the recalls, Samsung announced Monday that Note 7 owners who switch to Samsung Galaxy S7 or S7 Edge smartphones can get 50 percent discounts on upgrades to Galaxy S8 or Note 8 smartphones next year if they return the S7 or S7 Edges.
