On Saturday (yesterday), I installed DJI Go 4 on my Google Nexus 7 II, then installed the latest DJI firmware on my
P4P, and flew 3 times using DJI Go 4 as my control platform. The first flight, I had various connection problems. I could detail those problems, since I recorded the screen video of the entire flight, but after that first flight I uninstalled Litchi, and then had no connection problems on the 2nd and 3rd flights. As I've said before, I don't know how the interaction between DJI Go 4 and Litchi works, and I don't know why neither of them will work properly if both are installed on your Android device. My reason for wanting to see if removing (uninstalling) Litchi would fix the DJI Go 4 connection problems was that some of the new color profiles looked intriguing enough that I wanted to be able to use them if at all possible.
I could be wrong, but I think most of the new color profiles are actually new, rather than being the old profiles with new names. I'm thinking that videographers more knowledgeable than myself might be able to figure out for sure which of the profiles, if any, are different from previous DJI color profiles.
On my first flight, I recorded video using every one of the 13 color profiles. The names are: None, True Color, D-Cinelike, D-Log, Film, B&W, Cool, Twilight, Pale, Old Photo, Warm, Blue, Blockbuster. The D-Log profile, incidentally, is still locked at 500 ISO.
After reviewing the video from my first flight, the profile named Film looked particularly interesting to me, so that's what I used for the second flight.
Video from the second flight, "Film" color setting, no color grading in post. Style settings -1, 0, 0. 4K/30, shutter 1/60, ND16 filter, white balance 5200K (Sunny), aperture 4.0, ISO 100, H.264, MP4 file format:
