Thousands of Galaxy Note7 phone owners in Australia have been told to turn off their phones and return them to stores after reports of batteries catching fire and exploding while charging.
The recall of more than 50,000 phones came after an Australian man posted pictures online claiming his phone had caught fire while he was asleep.
"My phone Note7 has exploded this morning just like many other cases. I am okay, glad I woke up right away," Tham Hua posted on Facebook on Monday night.
He woke up and slapped the phone off his bed where it had been charging overnight. It burnt his finger, his hotel bedsheets and carpet.
Consumer advocacy group Choice recommends customers ask for a refund rather than a replacement.
"You don't want one of these flaming devices in your pocket," Choice head of media Tom Godfrey said.
"Put your family first, put your safety first and get a refund."
Citing "isolated battery cell issues", Samsung Electronics Australia announced the voluntary recall of the phones late on Monday night, following similar moves overseas.
The company last week urged customers in 10 countries including the United States and South Korea to return the phones after reports of 35 cases of devices catching fire while charging.
Samsung is investigating a "small number of reported incidents" in Australia but won't confirm Mr Hua's case.
"The safety and ongoing satisfaction of our customers is our top priority," Samsung Electronics Australia vice-president IT and mobile Richard Fink said.
The company said customers who bought phones directly from Samsung can get replacements or full refunds. Others should return them to the retailer.
In 2013 Samsung recalled about 150,000 washing machines in Australia after 15 house fires were linked to top-loader models.
Since then 300 incidents, including more than 200 house fires, have been linked to the washing machines in Australia and tens of thousands are still believed to be in homes around the country.
