Check your USB connection

  • On your phone, check that your USB connection is set to File transfer mode.
  • Try a different USB cable. Not all USB cables can transfer files.
  • If your phone detected moisture in the USB port, which can occur in high humidity environments or if the phone came in contact with water, unplug the phone, wipe it dry, and gently shake it about 10 times with the USB port facing downward to remove moisture. Place it on a cloth to air dry, or use a fan to help dry it faster.
  • To test the USB port on your phone, connect your phone to a different computer.
  • To test the USB port on your computer, connect a different device to your computer.
