One more Galaxy Note 7, which its owner claims was a replacement unit, caught fire in the US. A man named Michael Klering in Nicholasville, Kentucky said his replacement unit was slightly more than a week old before it caught fire.

"I was scared to death for a minute," Klering told local media WKYT, adding when he woke up, his bedroom was "just covered in smoke". It was then he saw his phone was on fire.

The replacement unit, as Klering explained, was not plugged in to change when it caught fire.

"The phone is supposed to be the replacement, so you would have thought it would be safe," he added.

He wanted to get this information out to public so that the same does not happen to others.

"They're in kid's pockets, people's cars, all kinds of things. We saw with the first ones. Samsung needs to do something to get these off the market," Klering said.

This fire incident comes after a Note 7 caught fire on-broad a Southwest Airlines flight from Louisville to Baltimore last week.

The plane was evacuated as the phone started smoking. The owner of the burnt device confirmed that was a replacement unit which he picked up from an AT&T store on 21 September.

The Federal Aviation Administration and the Consumer Product Safety Commission are currently investigating the latest incident.

A spokesperson for the Southwest Airlines told BBC, "A customer reported smoke emitting from an electronic device. All customers and crew deplaned safely via the main cabin door."

In a separate report, a 13-year-old Abby Zuis in Farmington said her replacement Note 7 phone melted in her hand. Abby said she felt a "weird, burning sensation" in her thumb while holding the Note 7 Friday afternoon. The phone melted the cover and had significant smoke damage and burn marks, reports KSTP.

Abby said she suffered a minor burn to her thumb.

This is third such case of replacement device catching fire.

In response to KSTP a Samsung spokesperson said, "We want to reassure our customers that we take every report seriously and we are engaged with the Zuis family to ensure we are doing everything we can for them and their daughter," adding the matter is now under investigation."

The Consumer Product Safety Commission (CPSC) said it is currently working to examine Zuis' phone.
