NEW YORK (CBS / AP) — The U.S. Consumer Product Safety Commission says owners of the Galaxy Note 7 smartphones should turn them off and stop using them because of the risk that their batteries can explode.

The agency also says it’s working with Samsung on an official recall of the phones “as soon as possible” and that it’s trying to figure out if the company’s replacement Note 7s are an “acceptable remedy.”

In a statement Friday, Samsung says Note 7 owners should shut off their phones and exchange them now for another device. But the company says new Note 7 phones will not be available until after the CPSC finishes its “process.”

Shares of Samsung Electronics Co. tumbled 4 percent Friday, the worst decline for the company’s stock since January.
