After much hesitation, I installed Litchi on my P4P, running FW 01.02.0304. It flew great for the two or three flights for my trials. Then I flew it with the DJI Go app again. I noticed a lot more interference, and loss of signal more frequently, in the same areas. The EXIF data on my photos also shows the wrong year in the date. I want to try and upgrade my FW, and then downgrade it back to the current version, to see if that fixes the interference and date issues. Then I'll wait before installing Litchi again. What kind of problems could I run into by changing around the firmware? I'm of the belief if it ain't broke don't fix it when it comes to FW upgrades, so I'm not too versed in FW changes.
