WASHINGTON (Reuters) - Owners of Samsung Electronics Co Ltd 005930.KS Galaxy Note 7 smartphones should stop using the devices and turn them off because of the threat of a battery fire, the U.S. Consumer Product Safety Commission said on Friday.

The CPSC said in a statement it was working with Samsung to announce an official recall of the devices as soon as possible. The agency said it is working quickly to determine whether a replacement Galaxy Note 7 is an acceptable remedy for Samsung or their phone carriers to provide to consumers.
