Samsung has reportedly stopped production of its Galaxy Note 7 as the company struggles with the smartphone’s recall and additional reports about battery problems, overheating and fires regarding replacement devices (including one incident prior to takeoff of a Southwest Airlines flight). “Samsung understands the concern our carriers and consumers must be feeling after recent reports have raised questions about our newly released replacement Note 7 devices,” the company said, noting that an investigation is underway. According to The Wall Street Journal, AT&T and T-Mobile “said that they would stop issuing new Galaxy Note 7 smartphones to replace the ones turned in by U.S. customers.”
