Hi, I have a Phantom 4 and a Nvidia Shield tablet. I have recently developed several problems while flying relating to image transmission. Specifically I am getting green bars, grey screen, and temporary loss of image. These problems have just started recently and before they started I was having good image transmission. In addition I have on several occasions I have received the message that Image Transmission has been lost and I should activate return to home. On another occasion the communication between the controller and the Phantom was lost. I was able to restart the app as the Phantom hovered and was able to regain control. All of these issues have just started after a recent firmware update and I suspect there is some issue with the update and or the controller update. Can anyone advise what steps I should take to remedy the issues. Is it possible to delete the firmware in the Phantom and the controller and re-install? Do the issues I am having suggest any other causes? Could it possibly be a hardware issue? Thanks for any advice!
