Samsung has not commented on the stories attributed to unnamed sources published by Korea’s Yonhap News Agency and the Wall Street Journal and did not immediately respond to an inquiry from The Washington Post.
Meanwhile, two U.S. carriers, AT&T and T-Mobile U.S. are halting sales of the smartphones.
“While Samsung investigates multiple reports of issues, T-Mobile is temporarily suspending all sales of the new Note7 and exchanges for replacement Note7 devices,” said a press release from T-Mobile.
“Based on recent reports, we’re no longer exchanging new Note 7s at this time, pending further investigation of these reported incidents,” an AT&T spokesperson told FORBES.
Korea’s Yonhap News Agency reported eight cases of fires in replacement phones, 5 in the U.S., one in South Korea and another in Taiwan.
Yonhap said the incident in Korea was determined by a laboratory test to have been caused by a “strong external shock or being squashed.”
