The SAMSUNG Android Bootloader Interface driver is a software component that allows your Windows computer to communicate with a Samsung Android device in specific boot modes, such as when the device is in Download Mode (Odin mode) or Recovery Mode. This is important for tasks like flashing firmware, unlocking bootloaders, or installing custom recoveries via tools like Odin (a popular Samsung flashing tool).

When you connect your Samsung device to a Windows PC in these modes, the computer needs the proper drivers to interact with the device. Without the appropriate driver, Windows may not recognize the device, and flashing operations or other advanced functions may fail.
