I made these mistake of purchasing the Phantom 4Pro + in March of last year.
The built in monitor is very nice, but the DJI software issues are a nightmare at best.
Software crashes are common, The farthest distance I have been able to fly my Phantom is around my 8,300 feet.
The video always shows that the camera has a “twitching” problem.
DJI per their norm, never returns my calls, even though they promise to. I could go on and on.
I have had the P4 Advanced Plus for five months, but just got a replacement back under DJI Care Refresh after a crash broke the gimbal. On my first long video flight I noticed a "twitch" in the video. I thought it might just be dropping frames when playing the video back, because it's hard to play 4K back on my laptop, where some players just freeze and some do better.
But since you mentioned a "twitching" problem I'd like to know more about that from you and other users of P4P and P4A with the same 1" camera, with and without the Plus controller.
