"Virtually no evidence" for claim of remote backdoor in Samsung phones

On Wednesday, developers of an alternative version of Google’s Android mobile operating system published a startling claim: Samsung’s S3, Note 2, and seven other models of Galaxy smartphones contained a backdoor that provides remote access to virtually all data stored on the devices. The code that allows access, which controls the phones’ baseband or modem processors, made it possible to remotely read, write, or even modify users’ files.
