I had a problem with accessing the various menu options for the video and camera settings for my 2 day old I2 (X4S camera), while running the DJI Go 4 App. It was on an iPad Air 2 with the latest Go App version (4.0.2). Initially I was not able to access the options for the various menu groups (Camera - Photo, Image Size, Image Format etc. and for Video - Video Size, Video Format, NTSC/PAL etc.) I then used my iPhone 6s and I was able to access the various Camera and Video menu options. I decided to change the various settings using the iPhone 6s to those most frequently used by me (based on my I1 and P4 experience). When I swapped the iPhone for the iPad the settings were as I had set them, but more importantly I was then able to access all menu options on the iPad. I'm not sure why this worked, but thought it might be the 21st century equivalent of hitting some piece of mechanical equipment with a big hammer. Not sure if anyone has experienced similar issues, but the fix was easy but not very intuitive. Can't wait to do more flying. The I2 appears generations ahead of the I1.
