Samsung said it's stopping sales of its Galaxy Note7 smartphone after some phones exploded while charging. The company also will replace models already in consumers' hands.

The South Korean company said in a statement that it found a "battery cell issue." Samsung said there have been 35 cases so far but it didn't specify the type of incidents. News reports in South Korea have chronicled fires during charging

Samsung has already shipped 2.5 million Note7 smartphones, the Wall Street Journal reported.

As of midday Friday, news of the Samsung Galaxy Note7 decision hadn't made it into all retail outlets we checked.

Consumer Reports shoppers found the phone available in a Best Buy in the New York City region and Orlando, Fla., and in some Sprint outlets in Florida. In addition, the phone still appeared on the Verizon website next to a "Buy Now," button. Amazon was offering the phone on its website, as well. 

T-Mobile, AT&T, and Sprint had removed the phone from their sites, and the majority of carrier stores we contacted informed us that the Note7 was not available for sale. 

Samsung said Friday afternoon that consumers can exchange their Note7 for a new one as early as next week. Consumers can also swap their Note7 for a Galaxy S7 or S7 Edge. Anyone who exchanges their phone will get a $25 gift card or credit for that amount from their carrier.

In the meantime, our experts advise that Note7 owners should disconnect the device if it becomes unusually hot during charging and take the phone to the retailer where it was purchased.

The Note7 is the second smartphone Samsung has had problems with recently. After its Galaxy S7 Active was marketed as being water resistant, that smartphone failed Consumer Reports’ water-resistance test. Samsung said it has now fixed that issue.
