A replacement model of the fire-prone Samsung Note 7 smartphone began smoking inside a U.S. plane on Wednesday, the family that owns it said.
Samsung Electronics Co said in a statement on Thursday it was working to recover the device and to understand the cause.
“Until we are able to retrieve the device, we cannot confirm that this incident involves the new Note 7,” the South Korean company said.
The fault has prompted fresh investigations by the Consumer Product Safety Commission and the Federal Aviation Administration.
Observers said that a problem with the replacement for the Note 7 model would create a new, embarrassing and potentially costly chapter to a global scandal which had hurt Samsung’s reputation.
They said it could also add new dangers for consumers.
Indiana passenger Brian Green’s phone began emitting smoke inside a Southwest Airlines Co flight to Baltimore from Louisville, Kentucky, his wife Sarah told Reuters after speaking with her husband.
She said that Green had replaced the original phone about two weeks ago after getting a text message from Samsung.
The world’s largest smartphone maker announced a global recall of at least 2.5 million of its flagship Note 7 smartphones in 10 markets in September due to faulty batteries causing some phones to catch fire.
The U.S. Consumer Product Safety Commission (CPSC) is in touch with the Federal Aviation Administration (FAA), Samsung and the phone’s owner to gather facts, Chairman Elliot Kaye said in a statement.
Kay reminded consumers that they could get refunds for the troubled model.
The FAA said in a statement that it had confirmed a Samsung phone caused the smoke on the Southwest flight and that it was investigating the incident.
Technology news site, The Verge which earlier reported the incident, reported Brian Green as saying the phone was a replacement.
Green posted a picture taken by him of the packaging.
The picture showed an identifying label with a black box, which Samsung has described as the indicator of a replacement phone but a spokeswoman for Samsung declined to comment on the picture.
Samsung customers in China have reported problems with phones that have the same battery as the global replacement model, but Samsung has said it examined the Chinese phones and found the batteries were not at fault.
