Could not get my P4P to connect to Samsung Galaxy Tab 2 with Android 7 installed. It would not let the DJI GO 4 app use the USB cable. If anyone is having similar trouble the cure is as follows:-
Aircraft and controller - powered up. Connect smartphone or tablet ( must be switched OFF ) to controller with USB cable. Then switch on phone / tablet. After it boots, touch the DJI GO 4 app icon and a small window will then appear with message "Allow the app DJI GO 4 to access the USB accessory ? " Cancel OR OK. Touch OK and the app will connect in the normal way. With any other switch-on sequence the message will not appear and the app will not connect to the aircraft. Android 6 works normally on my smartphone, without having to go through this switch-on procedure.
