I noticed that the last couple times when flying using my Nexus 7 tablet that almost immediately the video feed from drone is literally cut in half long ways across my tablet. I have tablet hooked to controller with DJI usb cord it acts like it's a range issue.. Literally 15 feet away it starts. However when I hooked my Samsung S7 through the same cord it doesn't do it at all. This is new it hadn't done this when I first got the drone around Christmas. Any help would be appreciated as the tablet is the preferred way to fly
