The first one I got couldn't connect to the Type-C slot in my S9 phone, couldn't get in far enough. The second can connect, but there are no instructions on how to transfer files from the phone to the drive and vice versa. After looking at a lot of written and video materials on this, I still cannot complete this task. Where it says I should have a "Copy" command in the top right corner, there is no such command. There's one at the bottom of the screen, but it only copies to itself, which is pretty much useless. For now I can only use it as a simple flash drive in my computer's USB port.
