Samsung is resuming sales of its Galaxy Note 7 smartphones in South Korea following a safety recall. They are set to return to Europe on 28 October.
The company asked customers to return their handsets after some users reported their phone had "exploded" during or after charging.
The firm said that battery problems were behind phones catching fire.
Samsung had sold about 2.5 million Galaxy Note 7 devices across the world before the recall.
In South Korea about 80% of those sold have been returned to be replaced.
In Europe and North America the figure is lower but still way above 50%, according to company sources.
Samsung insiders say that 95% of the people returning their handset are opting to continue with a Samsung model. There is - they say - huge customer loyalty.
But there has clearly been a big cost, one on which a monetary value is impossible to determine exactly.
