SEOUL, South Korea — 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. Samsung recalled the Galaxy Note 7 phone because it tends to overheat. It recalled replacement Note 7s after finding they also were prone to catch fire, the company stopped making or selling them. The company did not immediately respond to called and emailed requests for comment.
