SEOUL: Hundreds of South Korean Galaxy Note 7 smartphone owners filed a lawsuit against Samsung Electronics on Monday over its handling of the fire-prone device. Attorney Peter Young-Yeel Ko, head of the Harvest Law Firm, said the 527 plaintiffs 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 Electronics is offering an upgrade programme option to Galaxy Note 7 customers in South Korea who trade in their recalled device for a Galaxy S7 phone, marking its latest attempt to retain customers.
