Something strange manifested on my mini 3, now all of a sudden when I first turn it on, the gimbal makes a strange buzzing sound for a few seconds which never happened before.
No crashes or mishaps, just out of the blue this annoying vibrating buzzing sound. Sometimes it makes a noise for longer period of time, but it used to be completely silent.
I did auto gimbal calibration and made no difference. It sounds like something is grinding up inside, whatever the case, it is a new unwanted development.
What to do in this situation?

Hi there. Thank you for reaching out and we're deeply sorry for the inconvenience. Please make sure to remove first the gimbal protector before you turn on the Mini 3 Pro. We recommend also doing all the updates as there are new updates released today, October 26. 2022. Firmware versions are as follows:
Aircraft Firmware: v01.00.0400
DJI RC-N1 Remote Controller Firmware: v04.14.0400
DJI RC Remote Controller Firmware: v01.02.0000
DJI RC Pro Remote Controller Firmware: v03.01.1000
DJI Fly App iOS: v1.7.8
DJI Fly App Android: v1.7.8

After performing all the updates, kindly do the gimbal calibration once again. If the issue persists, I'm afraid that you may consider sending the unit in for a proper diagnosis. You can contact our support team to start up a ticket at https://www.dji.com/support. Also, the warranty can be applied depending on the outcome of the damage assessment including the warranty period of your unit. Thank you for your kind understanding.

Thank you for thinking that people are too stupid to realize that a gimbal cover must be removed and have no concept of what it is, how insulting...
I did not just buy the drone and make a first post here, I have had the mini 3 for over 3 months without issue and without gimbal problems.
I dont see how a firmware update can fix something which has manifested itself for no reason, whereby the drone was working 100% with the same firmware.
For what its worth, the mini 3 is using the 1.03 firmware since it was released, and since 1.04 is a point of no return I dont see that as any means of fixing anything, more of a "lets hope and pray". Due to the horrible track record of DJI with firmware I dont want to take a chance to brick my drone.

I have powered the mini 3 on over a hundred times and it has always been silent, now suddenly it makes a vibrating noise for around 3 seconds during startup check.
It has been clearly stated that the drone has NO DAMAGE WHATSOEVER, but as usual a uselss canned response from DJI support is the only "support".
I have seen others post on this forum having the same exact issue and seemingly with similar circumstances, at present I dont feel like scouring this forum for the responses, it would be like looking for a 30064 error on here with over 800 responses (just 1 example)

I had 2 drones do this. Had DJI replace them each time.

It seems that this issue even happens right out of the box before a flight, such amazing quality control....
I found a couple of other threads with the same issue:
Gimbal noise
More gimbal noise

Why does DJI always act like the incident is a one-off and like they have never heard of such a thing?
This should be in a "known issues thread" along with all the wonderful 30064 errors and other shortfalls

Good Morning.
I have precisely the same problem since yesterday. I turned on the MP3 to take a flight and noticed that the gimbal made a noise I had never made before. I've turned it on and off a number of times, sometimes it takes 2 to 3 seconds, other times it takes a little longer!
Then it stops and the system seems to work normally.
What could have happened? the noise is really uncomfortable.

Well, I updated the firmware and it made no difference at all, if anything, it buzzes more during the startup, now it is 2 tones of vibration lasting around 5 seconds.
I knew a firmware update would not stop motor buzzing but DJI loves to give useless information and try to evade issues.
There are plenty of other users with this same DEFECT.
So since I am in South America what is the procedure to get this fixed?
Now my mini 3 is stuck on 1.04 firmware and cannot downgrade.
FWIW the issue started out of the blue using the 1.03 firmware and the drone was never involved in any crash or accident.

My drone also have the gimbal noise at startup. I feels like it started to appear when I upgraded to 1.00.0300 firmware. I would love to downgrade if it was possible.

Mine was fine on the 1.03 until a couple of weeks ago, and the noise just started randomly, sometimes it vibrates longer than others, sometimes only vibrates with 1 tone, sometimes 2.
This seems to be a hardware defect where no firmware can fix it.
Just to rule out the firmware, I followed DJI instructions to update to 1.04 and now I cannot revert to the old firmware.

Hi, MacGyver007. Thank you for the response. We apologize for the confusion, we don't mean to feel you that way, we just need to put every small and big detail to help with the customer's concerns. Moving on, please send us a video with following the methods below for further assessment:
1. In a quiet environment, place the aircraft on a horizontal platform. Remove the propellers and power on the aircraft. Push the remote controller sticks to start up the motors.
2. After the motors rotate without a load, listen carefully to determine whether each motor has a metal friction sound. If there is the sound of any friction or foreign matter, proceed to Step 3.
3. At a place 50 cm above the aircraft, shoot a video more than 20 seconds long without blocking the recording device’s microphone.

Please upload the video/s to Dropbox or Google Drive and provide us the shareable link via PM. We will wait for your update. Thank you for your cooperation.

Hi,
The prop motors are fine so your suggestion for that test seems to be pointless.
My GIMBAL makes a noise similar to this video, but for a longer period, and now its a higher pitched vibration followed by a lower pitch lasting around 3-5 seconds.

There is no error message in the app, gimbal calibration works fine, I will try to shoot some video to see if there is any instability, but at any rate, my mini 3 was not like this when I bought it over 3 months ago, it was completely silent for the gimbal. To me it is a hardware defect similar to the faulty o-ring in the camera assembly.
This product was rushed to market with too many issues, and still has too many unresolved ones.
Edit: I just did a test flight with video and there is no jello effect as seen in other videos, video looks ok to me.

Hi Dji Team,

I Have bought a DJi Mini 3 Pro Drone from Malaysia
And facing thr same issue where gimbal is making a sqerky noise , and on High Altitudes Drone Footage is wobbly , But in Sinilar Heights in Night drone footage looks good.
What can be the Problem?

Hey man. My mini 3 pro was doing the same thing. Its the shock absorber in the gambal. The gimbal has 3 plastic tabs that pressure fit in the rubber shock absorber. I fixed my with no new parts. Poped it back in. And it's fine. Back to normal. Let me know if you have any questions.
