I have a Phantom 2 Vision. It has been working quite well for over 6 months. I have plenty of video to show which was recently in the local news. I needed more FPV range so I purchased the newer extender (RE700) and again this has been working very well. I was using the DJI app version = 1.0.38 with a Samsung Galaxy S4. But I wanted more controller range and better video so I purchased a new P2V-plus with the gimbal. The app I was using with the P2V does not work very well with the plus model. I had no control over the camera gimbal. So I updated the app to the current 1.0.52. Things are working well now with the stock P2V-plus. But now with the updated app the camera FPV does not work with my original P2V. What I mean is that the image I am seeing on my phone is now a garbled mess and useless. I have changed camera setting, rebooted the camera, re-charged everything, and this problem will not go away. I assume the problem is with the app since that is ONLY thing that changed with my P2V setup. I hope I don't have to buy another smart phone just to use a different app version. Any thoughts or suggestions would be appreciated. Maybe I need to downgrade the app if that is possible.
