Samsung's exploding battery nightmare may not yet be over, amid a report from China that a new Galaxy Note 7 burst into flames this week. Update: The replaced and supposedly safe Galaxy Note 7 continues to explode, with at least seven cases reported in just the last few days. Samsung has temporarily halted production of the Note 7.

A Chinese customer has reported that a Note 7 that he bought this week exploded within 24 hours of acquiring it from an online retailer, causing minor injuries to two fingers and damaging his Apple MacBook.

“We are currently contacting the customer and will conduct a thorough examination of the device in question once we receive it,” the Korean company said in a statement sent to Bloomberg. Samsung, following an earlier Note 7 fire in China, had previously reported that there were no issues with the batteries used in Note 7s sold there.

The Korean electronics giant was forced to issue an embarrassing global recall at the start of September for the Galaxy Note 7, after dozens of early adopters reported that their handsets had exploded. Airline regulators in India and the US banned customers from using their phones in the air, while a six-year-old child in the US was hospitalised. [Note: In the last case, the exploding phone was apparently a Galaxy Core Prime, not a Note 7 as initially reported.]

Samsung said it had found the cause of the explosions, and insisted that the flaw was only present in a tiny percentage of the 2.5 million Note 7 handsets it had sold at that point, and offered to replace each of them at an estimated cost of $1.35 billion (£1.04 billion). If this new report from China turns out to be true, the cost could become much more severe.

According to a Bloomberg report last week, Samsung's problems arose after their executives decided to rush the Note 7 to market. They'd heard that the iPhone 7 would be underwhelming, and wanted to capitalise by loading new features into the handset that should be Apple's main competitor. This, it is implied, is how errors crept in.

Samsung says that around 60 percent of Note 7s have now been recalled in the States and South Korea, while 57 percent have been exchanged in Europe. At the current rate of exchange, the company says the recall will be completed by early October, meaning the phone should go back on general sale in Europe by October 28.

Ars has asked Samsung for more comment on the issue but hasn't yet heard back.
