You can connect your Samsung device to the PC using the official support software, Samsung Kies (available for all Samsung phones). You need a USB cable or a WiFi connection available for the PC. Please make sure that when you install the software you allow all prompts regarding drivers because if you cancel or ignore those prompts, the phone will not be correctly installed when you plug it to the computer.
Upon connecting the phone, please wait for 2-3 minutes for a successful connection because the process could take a little longer.
