Turn Android Beam On / Off - Samsung Galaxy S® III
Android™ S Beam can be utilized to transfer data (e.g. web pages, videos, place page in Maps) from one Near Field Communication (NFC) capable device to another when only a few centimeters apart, typically back-to-back.
NFC may not function properly with the use of a 3rd party battery. To ensure functionality, only utilize the Samsung designed battery with Near Field Communication printed on the battery label.
