An anonymous reader quotes a report from Bloomberg: ATT Inc. is considering stopping all sales of Samsung Electronics Co.'s flagship Galaxy Note 7 over concerns about the smartphone's safety, according to a person familiar with the situation. A final decision will likely come as soon as Friday, said the person, who asked not to be identified because the deliberations are private. ATT spokesman Fletcher Cook declined to comment. Like many competitors, the second-largest U.S. wireless carrier is already offering alternative smartphones to people who return Note 7 devices. Samsung started replacing the Note 7 last month because of a flaw in its lithium battery that can lead to overheating and pose a burn hazard to customers. Airlines have banned customers from using the smartphones on flights, and the evacuation of a Southwest Airlines Co. plane earlier this week was blamed on smoke caused by a replacement device. ATT's move would be a further blow to Samsung. The wireless carrier is the third-biggest customer of the South Korean company, according to estimates compiled by Bloomberg. Samsung is already facing a bill that analysts estimate stretching into the billions of dollars for the recall of 2.5 million Note 7 phones that it announced last month. A U.S.-based Samsung spokeswoman didn't immediately have a comment.
