    No it didn’t. I still can’t see my drives on my Android device and can’t transfer files from Windows to the device. I’m going to have to take it to T-Mobile and see if they can help. This is why I stuck to a Windows Mobile phone so long; I am a graphics artist and put samples of my work on my phone. I can’t do this with an Android phone and will have to carry a separate device to show my work to potential customers.

  2. I have tried everything and simply cannot transfer files from my Android phone to my Mac. I did everything described here, it made no difference.

    • Try below Way, it will surely work for you.
