I bought this to go with my Huawei Mate 20 Pro. We got off to a shaky start, it didn't work! However, I had a little tinker around, enabled developer mode, enabled USB debugging, then it worked an absolute treat. Once plugged in, a notification appears in the status bar, drag the bar down and you get the option to View or Unmount. When you press View, it opens the file explorer up in the right place and you can view your memory card files easy as pie!
