Major US wireless carriers have rejected the idea of a “kill switch” security measure being added to Samsung’s popular Android phones, according to The New York Times. San Francisco district attorney George Gascón has been negotiating with Samsung to add tighter anti-theft features to its products, but mobile providers and the CTIA have reportedly come out in opposition to the plan. After reviewing emails between a developer and Samsung, Gascón is convinced that’s because the companies fear losing reliable profits that come from selling cellular insurance plans to customers. These protection plans often cover lost or stolen items, but they almost always demand a high deductible (in addition to a regular monthly fee) when phones need to be replaced. The carriers obviously have a different take.
