Samsung investigates reports of heat problems with replacement Note 7

Samsung Electronics Co Ltd on October 10 said it is investigating reports of heat damage issues on new Galaxy Note 7 devices after US carrier AT&T Inc said it would stop exchanging the device to customers.

"If we determine a product safety issue exists, Samsung will take immediate steps approved by the CPSC to resolve the situation," Samsung told Reuters in a statement.

A Southwest Airline plane was evacuated last week after a Note 7 phone began smoking inside the plane. The family that owned the device said the phone was a replacement device that Samsung has said uses safe batteries.
