Update on the Sabaj Da2 I recieved on Nov 30. I previously said no issues with android, then the next time I tried Spotify on my Samsung the dreaded buzzing, ok on Pandora. Then the next day Pandora buzzing as well. Google reveals otg usb reads the Sabaj as a hard drive or worse, a device that needs charging. Unhelpful stuff about accessing the usb settings and changing to MIDI, most android phones won't let you access that. Finally somebody says turn the app on before hooking up the Sabaj, bingo. I remembered this is what I had done in the previous session by chance. So far no more buzzing, I didn't read back through the thread to see if this had been covered or not. Any experience with this from others?
