I was going to start a similar thread, but I saw yours, so I will add my findings:
I have been complaining about P4 video transmission issues for the last 2 weeks. And of course I complained back with app version 2.8.2.
Some (including myself) thought it was my iphone 6 plus, which I upgraded from an iphone 5 for the same video issue back in May.
I just performed the following test and I hope my finding help DJI correct this:
I placed the P4 outside under the hot sun with the battery at 95%. I kept the RC/iphone 6 p inside an air conditioned room.
When the battery got to about 89% I was getting video transmission issues. I moved the P4 to maintain it in the sun, and at that point I received a Vision Sensor error and error 40000. I thought it may have been because I manually moved it and I may have obstructed the vision sensors. Please let me know what error 40000 is?
I kept it there and the video got worse. I will post videos later, but I used an old camera, because I do not have video recording on my iphone other than litchi, but I wanted to use the DJI-go app.
I then switched between dji-go an litchi to see if the app has any affect; the answer is no, both apps had very bad video now.
I then moved the P4 inside an air conditioned room and after a few minutes, the video improved. Eventually, it was back to normal.
I kept the P4 inside and I then took the RC and my iphone 6 p outside in the hot sun. The video stayed good, even though my iphone 6 p gave up, and I got a warning, that the Temperatre was too high.
This test is telling me that the video transmission issue, which started after the last firmware update is pointing to the P4.
I also undertand that usually software is not affected by heat; but, from my experience as a hardware/software engineer, software can cause the hardware to operate hotter, or not as efficient, or affect the performance under adverse envronmenetal conditions.
