Phantom 3PRO. The latest firmware. Samsung S5 (SM-G900FD, Android 6.0.1) is not connected DJI GO, Litchi. Vertical studio connected. Previously, everything was working fine.
With Samsung TAB S works.
P.S. Sorry - google translator.

Hello Mick, for the samsung devices, please make sure both the USB debugging mode and MTP mode are enabled when it connects to the RC.

Besides, please try with different cables.

If you are using a Samsung Galaxy S5 with both apps installed, there is an issue with Android Marshmallow 6.0.1.
It will not allow you to have both apps installed on the same device. If you uninstall either Go or Litchi, it should
connect just fine. Mine worked just fine on Lollipop until the Marshmallow upgrade.

Hi,

I had the same issue after updating Samsung S5 to Marshmellow.

Both DJI  and Pix4DCapture were installed. Removing Px4DCapture resolved the issue and DJI Go is now working.
