I have the following

Ios:11.2.5 ( latest)
Dji go 4.2.5
And  currently fw p4p 01.05.0300

I am not so happy with .0300 fw ( videofeed lag and trembling take off and landing when in touch with ground,anyway posted theseissues before)therefore thinking
about downgrading firmware back to  01.04.602


My question now is:

Does any on anyone has combination

Ios 11,2.5
Dji 4 app: 4.2.5
And the fw .602

If yes , do you have any problems?

I have all the latest firmware you have stated at the top and have had no issues with video feed or lag with my P4P.

Lagging of the video feed is more about what phone or tablet you are using on the controller than any of the other software factors. You have not indicated what you are using.

Sorry I misunderstood ! I have the above firmware 01.05.0300  Go4 4.2.5 and ISO 11.2.5 and am not having issues.

As Geebax said.

I had lag with my iPhone 6 but not with my iPhone 8

And with all the latest update ? If you slowly take off ( just on the edge of engine idle and take off, and also upon landing , when drone touches ground)in other words slowly throttle up, you do not notice any trembling of the forward engine arms?

I can't say that I do, are you saying the front propeller arms are shaking?  If so inspect for loose front propeller motors compared to the back, I had a guy last week with a P3 Standard have slack in one of the front motors that caused the same thing  on his and it ended up being loose motor mount screws.

I just seen over on the DJI P4 Standard section that a few people are having the same issue your talking about and seem to think it has to do with the firmware update as well, shaking when motors slow and one other did have loose motor screws after only 10 hours of flight time?

Same firmware, no issues. I hope your problems get solved!

Hi there, may I know how long the lag persists? Is the channel stable when the issue appears? Would you mind sharing us some videos and About page of mobile device for double check? Thanks so much!
