I'd use tablets that are known to work.
I am having a problem getting my Samsung Tab A, model no SM-T355Y to connect via my radio controller to my DJI drone. The issue is that the DJI app is not connecting because when I plug the usb cord into the tablets port it starts to charge rather than go into MTP mode. I have unlocked developer options and selected either MTP or PTP but neither action actually changes the status of the port, it continues to see the radio controller as a charging source.
How can I force the port to mtp and see the controller so that the app will connect.
