The SAMSUNG Mobile MTP Device driver is a Media Transfer Protocol (MTP) driver used by Samsung mobile devices to facilitate communication between the mobile device (such as smartphones and tablets) and a Windows computer. This driver allows for the transfer of media files (such as music, photos, videos) and other types of data between your Samsung device and the computer when connected via USB. It also enables Windows to interact with the device in a way that allows you to manage files, backup data, and even install certain apps (for developers) via Android's MTP protocol.
