Check for third-party software conflicts

Certain phone and cellular device connectivity software from vendors like Samsung, Nokia, Bora, Novatel, Sony, Android, LG, Sierra, Huawei, Pantech, or Motorola might cause your device not to be recognized. If you have such software on your computer:

1. Uninstall the phone or cellular connectivity software temporarily, and test. Contact the manufacturer of this software for assistance in doing this. If you use the third-party phone or cellular device for your Internet connection, try connecting to an alternate network using Wi-Fi or Ethernet.
2. Remove iTunes and all related Apple software.

   Remove and Reinstall iTunes and other software components from Windows XP
   Remove and Reinstall iTunes and related software components for Windows Vista, Windows 7, or Windows 8

3. After reinstalling iTunes, test the device.
4. If you still need your third-party phone or cellular connectivity software that was removed, reinstall the software and test your device to ensure it still functions with iTunes. Contact the vendor of your phone connectivity software if the issue returns.
