I've had my Phantom 4 since June and on my various flights, everything seemed to work OK until . . . Last Friday I dropped the RC controller & tablet due to the neck lanyard snapping. The controller seems OK from the outside, but the tablet (an Alcatel onetouch pixi 3 (10) ) dropped off and the screen is now cracked. I managed a flight within minutes of the mishap and all seemed OK - steady image on the dji GO app etc. On the Saturday, I tried connecting up again and the image seemed to be breaking up on the app - even when the drone was stationary on a table. However, I bought a smaller replacement tablet (ASUS ZenPad C7.0) on the Saturday and still have similar problems with the image breaking up into either "blocky" parts - or bands of the screen go green. It seems to take a 5 or 6 seconds for the displayed image to catch up. The images and video recorded onto the micro SD card on the drone seem OK. The system status button at the top centre of the screen displays various messages, including one about "Image transmission signal weak" - and that even when the distance between my drone and the controller is about 10 cm! Sorry that I haven't got any images that I could attach. Any suggestions that you could make will be most welcome!!
