Can't Find your Android:
- Restart your phone and restart your computer. You'd be surprised how often this fixes things.
- Make sure you are using a USB DATA cable! Accidentally using a charge cable will not allow data transfer with the computer.
- On Windows, download your the Universal ADB Drivers. If that doesn't work, try installing your manufacturer's drivers.
- Enable ADB debugging
- Set your USB mode to PTP (it is usually MTP or Charge Only)
