Samsung Electronics said on Monday it is adjusting shipment volumes for Galaxy Note 7 smartphones due to reports of some of the devices catching fire.

Samsung, in a statement, said the adjustments were being made in order to conduct in-depth inspections and to improve quality control. The firm did not elaborate further.

The comments come after a Yonhap News Agency report suggested that the company had suspended production of its phablet device, in what is a further setback for the tech giant trying to manage its worst ever phone recall crisis.

Samsung's decision to temporarily halt Note 7 production was done in cooperation with authorities in China and the United States, as two U.S. carriers have stopped exchanging or selling new Note 7 phones, Yonhap News Agency cited an unnamed source at a Samsung partner firm as saying.



Samsung did not immediately comment on the Yonhap report.

Problems with replacements for the Note 7 model would create a new and potentially costly chapter to a global scandal which has hurt the reputation of the world's biggest smartphone maker. It also could add new dangers for consumers.

AT&T, the No.2 U.S. wireless carrier, said on Sunday it will stop exchanging new Note 7 smartphones due to reports of fires from replacement devices that Samsung has said used safe batteries.

No.3 wireless carrier T-Mobile US said it was temporarily halting sales of new Note 7s as well as exchanges while Samsung investigated "multiple reports of issues" with its flagship device.

T-Mobile offered customers who brought in their Note 7s a $25 credit on their phone bill.

Samsung announced on Sept. 2 a global recall of 2.5 million Note 7s in 10 markets including the United States due to faulty batteries causing some of the phones to catch fire.
