LG G4 not recognised by Android Studio

Had the same problem and tried everything mentioned above with no success. What ended up working for me was downloading the LG Android USB device Drivers which can be found here: http://www.mylgphones.com/lg-android-usb-device-drivers

The latest drivers didn't work for me so I downloaded the second latest and voila! It worked! Hope this helps.


None of the answers here worked for me until I turned on USB debugging mode in Developer Options.

For completeness, the steps are:

  1. Go to Settings > About phone > Software info
  2. Tap "Build number" 7 times until it says that you're a developer
  3. Go back to Settings, and tap on the new "Developer options" item (second last in the menu)
  4. Enable "USB debugging"
  5. Plug in your phone
  6. Change from MTP to PTP mode
  7. Allow the computer to access your phone (there should be two messages - one of them should be for the RSA key fingerprint)

And that should do it. Run adb devices and you should see the phone.


So i restarted my device, and switched USB options from MTP to PTP. and for some reason it worked. I dont know why. Thanks for answers above, much appreciated
