Samsung is recalling the Galaxy Note 7 worldwide over battery problem

Samsung is recalling millions of new Galaxy Note 7

smartphones worldwide after reports that the devices can catch fire while charging.

The massive recall of one of Samsung's flagship devices is an embarrassing setback for the world's biggest selling smartphone maker. The Note 7 was unvieled just a month ago.

Samsung said Friday it had found a problem with the battery in some of the phones and was halting sales in 10 countries, including South Korea and the U.S. It will offer customers a new product for free in the coming weeks to replace the 2.5 million Galaxy Note 7s that have been sold.

Samsung said devices in China don't appear to be affected because it used another battery supplier. But it was unclear if models sold in China would nonetheless be recalled.

Target said Friday that it has stopped selling the phone and is working with Samsung to replace the devices already sold in stores and online. U.S. mobile carriers AT&T, Verizon, T-Mobile and Sprint have suspended sales. Meanwhile, Sprint is offering up similar devices for customers to use during the recall process.
