Dolphin not connecting to Android devices via USB

I have encountered the following problem:
Dolphin file manager does not recognise Android device connect for file transfer via USB.
I have been struggling with this for quite a while now


A solution I have found is as follows (works consistently for me):

  • Make sure dolphin is closed
  • Connect your Android device.
  • In your devices USB options (in the notifications area) change the USB function to ‘charging’ or ‘midi’
  • then change again to ‘Transfer Media Files’
  • Open Dolphin

You should now be connected to your device.

If you have adb installed, you may use (and hopefully improve) this very crude script:

adb shell svc usb setFunction midi
sleep 2
adb shell svc usb setFunction mtp
sleep 2
(dolphin &)
