1. Uninstal DJI GONew DJI go update does not fix disconnects. Has to spent 5 minutes playing with the app/tx/phantom/cable until I finally got it to work. Very frustrating. Running oneplus1 android.
Can I download the latest litchi beta from Google play?
2. Remove DJI folder from your device, by using file manager
3. Download DJI GO version 2.2.0
4. Make sure you have got USB debugging DISABLED
