Samsung confirmed that it has delayed shipments of its flagship smartphone, the Galaxy Note 7. The company said that "shipments of the Galaxy Note 7 are being delayed due to additional tests being conducted for product quality" in a statement to Reuters on Wednesday.

The decision comes on the heels of reports in South Korean media that at least two Galaxy Note 7 owners said their batteries exploded while their phones charged.

Samsung  has not specified whether the battery issues are the reason for this additional review.  Samsung has also not clarified how many markets are affected by this decision; the U.S. and international versions of the phone differ slightly, but have the same battery.

The company did not immediately respond to a request for comment.

The Galaxy Note 7 is the latest flagship phone for Samsung, and went on sale in stores Aug. 19 for $800 at full price. The phone has a 5.7-inch screen and a stylus, as well as an iris scanner that lets users unlock their phones with a glance. The phone has been fairly well-reviewed, though some have criticized its screen for being particularly prone to scratches and fractures.

Early demand for the Galaxy Note 7 has been high, and Samsung had already announced that it was having trouble keeping up. In July, Samsung reported that sales of its premium smartphones — including the Note 7's predecessor — had helped send it to its highest profits in two years. With the Note 7, the company has invested in an extensive advertising campaign to help keep sales rolling along and to top rival smartphones such as the iPhone.
