Updated the Phantom 4 a week ago to the latest version.

Now the gimbal acts strange:
Here is what I do at startup.
1. Turn on everything. All is connected ok and I have visual from the camera.
2. Take off...no problem.
3. Start recording...hmm. Here te wonky things start. The recording takes 20-30 seconds to start wheraafter the gimbal suddenly banks completely to the right. I can see the landing gear.
4. Gets an "aircraft disconnected" and then reconnect.
6. Camera and gimbal starts to return very slowly to center position, but horizon is off.

I have calibrated gimbal, IMU...you name it. I have even tried to re-apply the firmware.

NOTE: The max speed in Sports-mode is now limited to around 70 kph even with tail wind. Before the update I was able to get it to around 90 kph.
The copter seems more unstable in te air than before.

Conclusion:
I can live with the speed limitation (its not a race drone), but the "start recording" and gimbal problem is very annoying. Especially for important photo/video shots.

Come on DJI. Fix these bugs. Otherwise a great product.

Hi Dane, could you please provide us with the videos from the drone and use your mobile to record the drone's reaction of this case for a better confirmation? Appreciate it.

I Will Record One asap

I think this covers issue #3 to #6...quite a few users have this issue. It has been mentioned a bit throughout the forums already.
Local NZ distributor recommends waiting for a new firmware from DJI.

Yeah, what he^^^^^^ said.

Here is my short video of the problem.

Same behavior a lot of us are experiencing:

Hi Thor

This looks like the same issue first noticed after last update:- http://forum.dji.com/forum.php?m ... D368%26typeid%3D368

Come on, Thor! Do us all a favour and get this addressed by the engineers.

While we unable to record in 4K our hardware is no better than a cheap 1080 drone purchased off AliExpress.

DJI's reputation is taking a serious battering all over the Globe!

There was a shaking after the last firmware
What to do?

Yep. I see the same instability of the copter - even in zero wind conditions.

Thanks for the video. Had you tried another SD card? If you have tried, could you please name the card you have tested? I am collecting the data and feedback to our engineers. Thank you so much.

I will check the brand and model of the SD card asap. But it is a very fast one and a known brand.

For the gimbal shake issue, our engineers are working on it. Thanks again for the feedback, hope we address it quickly.

Thanks for bringing us the attention, I noticed that DJI Diana had forward your case to our engineers they had replied to your thread, since they got the attention, I will also inform the engineers your situation and help to find a solution quickly. Please wait patiently.

Thank you for your prompt response Thor, hopefully this will be resolved shortly.

The issue happens with both SD cards shown here.

The blue Lexar 16 GB card came with the drone from new...the gold Adata card is U3 32GB.

There is what is called a ground effect, if you are to close to the ground the air current caused by the blades will push the copter around. Mine does the same thing.

Yes I know, but I have seen this shaking at an altitude of 2 to 3m and above

Believe it or not 2 or 3 meters will do it.

Hi Dane, our engineers are aware of this case and working on it. We will have this case optimized via firmware upgrading. Sincerely sorry for the inconvenience and thank you for your patience.

Just roll back the firmware and it'll be fine. I wouldn't trust dji and their so called "updates" anymore. My drone fly's fine since rolling back. Why ruin a good thing.

Same problems here!!!!! And shaking on 20 meter height. Yesterday i had the same problem.

Greetz Jacko
Netherlands

The gimbal of my P3S also tilts without any reason, couldn't record it yet. Gimbal goes crazy and turns shaky in all possible directions. IMU and gimbal calibration couldn't help on this. Is this also known by the engineers Thor?

sorry for that... we have notice this problem last week and finally found out the reason yesterday , we will release the firmware as soon as possible TAT

Just throwing in that I also experience the "bucking" when flying. Doesn't matter if I'm 3 ft off the ground or 50ft. Please rush the update....I haven't been able to fly my P4 with confidence since I upgraded the firmware a month ago...

Hi, Dane, for the Phantom 4 recording issue, we have a beta for you to test. If you would like to be the tester, PM me your DJI email account and reply this thread to let me know you had provided your address. Thank you very much.

I had received your account and the beta should be available now. Please check. Let me know if you haven't got it. Thank you.

Got it and installed it. But I still have issues with the gimbal. Usually the horizon is very difficult to get straight. I have to land and do a gimbal calibration. The quirky/strange behaviour I posted earlier has gone though.

I am having this same problem. How can we roll back firmwares? My drone flew fine. Now I am under the latest firmware and having that camera/gimbal reset issue while recording...
I've reinstalled the firmware via DJI Assistant 2 and also with the iPad, re-calibrated gimbal/IMU/compass many times and still happens. I have a wedding shoot coming in less than a month...

So it means you always need to do the gimbal calibration even if you had done so very lately, right? Or is it the gimbal tilts every time you restart the drone? If it tilts slightly, you can adjust the gimbal Roll during a flight

Look like same as me. When used video and happen pop up show "No signal" and video become hanged and turned into gray. After few second then back to normal and video already stopped. Old android app v4.1.9 problem. Now change to new v4.1.10 app. Tested stable. I have not try yet 15 to 19 min flight if have issue or not. Today a bad weather. Heavy rain lol. U can try change to latest app and test.

The shaking appears to be the effect of an incorrectly calibrated gyroscope or missinformation from the gyroscope constantly trying to correct itself.
This has been noted many times since last update.
But im only an electronics technician so what would i know.
