Hello I'm about to buy a used phantom 4 pro, everything was ok, just one question , when I hit the record option, the iphone screen started to flickering black, but when watching the video on the pc, everything was ok.


is this normal? should I buy it or not?

Just to clarify, which iPhone model are you using along with Go app version? Does this happen both inside and outside?

What flickering are you talking about???

I do apologize for the vague terms, what I was asking whether this happens while both indoors and outdoors. In addition, do you notice this while only filming at high resolutions or does it happen at lower resolutions? Do you also have the app set up to cache video? For the latter questions, it could be that the app is straining to encode the video while simultaneously maintaining all the other functions in the Go app.

I believe he's referring to the black/green distortion that predominantly happens at around the 2:05 min mark and beyond.

No problem. I just noticed that you're also using the Go app and not the Go4. have you tried using the Go4 app to see if there's any difference? Is the unit fully updated to the latest firmware? Is hardware decoding enabled as well since you're using an iOS?

That was something that I missed, thanks for pointing it out. Due to when the P4/Go4 app were released, it along with the Mavic are those 'odd ball' products that are present in both apps. That could potentially be an issue.

I had to slow down the video 10 0,25 because he had his finger covering it...
