Oh dear. Seems I need to apologise for my review. Being ignorant if the differences in USB size is no Excuse really but I honestly did not note any sizing. So sorry. I am so pleased with your assistance to return this item & choose a compatible device. The other hiccup was not receiving your response to my query. Again I apologise
Cord does not fit phone. Even though information said it was compatible
I am sorry to know you are disappointed. You emailed us asking the same and I replied for you to check if the handset needs USB-C or Micro USB but I got no reply back from you. I checked online and Samsung S9 needs USB-C and you purchased a dock with Micro USB end so of course it wont fit and all it needed was a simple return/ exchange. Nothing is wrong with the product. Unfortunately you choose not to reply and just leave a bad review doesn't solve the problem on hand.
