Samsung Electronics says faulty batteries are mainly to blame for its smartphones catching fire.
It stopped producing and selling the Galaxy Note 7 as some handsets, sold mainly in the US and South Korea, caught fire just after sales started in August.
The South Korean firm released the results of its probe at a news conference on Monday.
The company says no problem was found with the phones themselves, but that design and manufacturing defects in batteries caused the fires.
Smartphone business division head Koh Dong-jin apologized for the company’s failure to ensure the safety of the batteries.
He said his division has introduced preventive measures. They include ways to detect problems caused by battery design as well as to improve charging tests for the phones before shipment.
He expressed his firm’s determination to place top priority on the quality and safety of its products.
