A plane has been evacuated shortly before take-off in the US after a Samsung Note 7 mobile phone overheated and started popping and smoking.
About 75 people who had boarded the Southwest Airlines plane in Louisville, Kentucky, were evacuated, an airport spokeswoman quoted by USA Today said.
Samsung's Galaxy Note7 smartphones were recalled last month worldwide due to the risk of them catching fire.
They went back on sale in South Korea on Saturday fitted with new batteries and are scheduled to go on sale in Europe on October 28.
Samsung admitted last month the phone, originally launched on August 19 and sold in several countries, could burst into flames while charging. Several airlines subsequently banned passengers from bringing them on board.
In Wednesday's incident, the Samsung Galaxy Note 7 phone had been turned off, according to news reports.
The phone overheated while the flight crew was giving their safety demonstration, a spokesman for Louisville fire department said.
A woman who said it was her husband's phone gave an account to the Louisville Courier-Journal.
"He said he had just powered it down, when it made a popping noise and started smoking," Sarah Green told the newspaper. "He took it out of his pocket and threw it on the ground."
Green said her husband's phone was a replacement Galaxy Note 7 issued after the recall.
Samsung said in a statement quoted by USA Today that until it could retrieve the phone, it could not confirm that the incident involved the new Note 7.
