Be aware! Samsung's latest software upgrade included an "antitheft requirement" that requires a person to use the ORIGINAL OWNER'S Samsung account ID and PASSWORD to recover from a factory reset. I had the local VERIZON shop try to do this in order to get rid of a persistent virus that my S4 phone had picked up somewhere. Since I had purchased this phone on EBAY, there was no way to get this info. So, unless the original owners of the phones ebay sells divulge their ID / PW (fat chance). these phones are junk once the occasion arises that a factory reset is required...
