Drone Model: DJI Mini 3 Pro

Firmware Versions:
The issue started after upgrading to 01.00.0700.
The problem persists after upgrading to the latest firmware 01.00.0900.

Issue Description:
After upgrading to firmware version 01.00.0700, I started experiencing transmission issues when using the automatic dual-band setting. The drone does not maintain a stable connection and fails to operate properly on automatic dual-band.
To make the drone function, I must manually switch the transmission to 2.4GHz every time I power it on. This problem remains unresolved after upgrading to the latest firmware version (01.00.0900). The manual switch is a temporary workaround but is inconvenient as it requires additional steps before each flight.

Steps to Reproduce the Issue:
Power on the DJI Mini 3 Pro.
Set the transmission to Automatic Dual-Band.
Start the flight and observe transmission instability or failure.
Manually switch to 2.4GHz in transmission settings to restore functionality.

Location Information:
Tested in multiple locations to rule out environmental interference, but the issue persists regardless of location.

I have the same problem

We are sorry for the inconvenience caused to you. Please ensure that the image transmission environment and the remote controller signal are both adequate when flying the drone. If this issue occurs frequently, please provide us with the flight data of the drone for further assistance. Thank you for your understanding and support.

This occured since the last update. If you set the RC controller to 2,4Ghz there's no problem. But when you set it tot 5,8Ghz or dual band the drone loses signal. This is not new for you there are many complaints about the firmware and losing signal when using the 5,8Ghz band or set the drone to dual band. Please do your research internal and fix this problem with a new firmware update. The drone is now useless because of the signal problem.

Thank you for your response and support. I’ve noticed that other users have reported similar issues with the transmission problem on 5.8GHz and dual-band settings, which seems to have started after the firmware updates (01.00.0700 till 01.00.0900). The workaround of switching to 2.4GHz manually each time is not a permanent solution and significantly impacts the usability of the drone.

I have gathered and uploaded the flight logs as requested. You can access them here: https://1drv.ms/f/s!ApbGMqZEFnh2hbwZs5bmwBqDLDGf-w?e=mJzWFH.

Given the growing number of complaints regarding this issue, please escalate this internally to your engineering team for further investigation and include it in the next firmware update. This issue makes the drone unreliable, especially in scenarios where automatic transmission switching is expected to ensure stable connectivity.

If additional details or steps are required, please let me know.

Thank you for your assistance.

Thank you for your prompt response and for forwarding the logs to the engineering team. I appreciate your efforts to investigate this issue and look forward to updates on the resolution.

Additionally, I kindly request that this thread remain open until the issue is fully resolved to ensure continuity and transparency for all users experiencing the same problem.

I’d also like to highlight that this drone is relatively new and still represents a significant investment. Experiencing such issues is quite discouraging and impacts trust in the brand. I genuinely hope that DJI can resolve this promptly, as it would go a long way in maintaining customer confidence and loyalty.

Thank you for your support and commitment!

Thank you for your patience.

Olá, pelo visto também estou com o mesmo problema, pois realizei a atualização do firmware para o 01.03.1900 e estou enfrentando problemas de desconexão, mesmo em alturas e distâncias pequenas... as desconexões acontecem e retornam do nada e até o "return to home" foi acionado automaticamente em algumas vezes... mas como não pensei na questão da banda, não fiz a alteração.

Também estou acreditando num problema com essa atualização, pois em voos anteriores não tive esse problema.
Obs.: Realizei a atualização no dia 28/12/2024 e os voos nos dias 30/12/24 e 02/01/2025.
  

I also have the same problem, since the last firmware update my drone loses connectivity, I was close to losing it.

I reported the problem and they gave me the same solution, which seems illogical to me when they see that many people have already complained about this problem.

I think that DJI should provide a technical and programming solution as soon as possible before we lose credibility in DJI quality products.

I have the same issues which started occuring since August 2024 update and its already been more than 6 months and still no solution for this. Also, all the DJI support agents have knowledge less than that of a 5 year old and they don't provide any helpful advice nor do anything to solve the problem. I have already lost my faith in DJI because I have invested more than $1000 in this product and now basically its a useless piece of junk sitting in my cupboard.

When could we expect an update about this issue? We are unable to use our drones now.

Any news? We need an urgent solution, it’s not safe to fly our drones

Hi there, may I confirm if the issue still persists? If yes, could you please share us a the flight logs and remote controller data for us to forward it to our engineering team and investigate further?

Hi there. We are sorry for the inconvenience. Are you referring to the image transmission of DJI Mini 3 Pro is disconnected and cannot be recovered during the flight?
Please provide us with flight controller logs for further assistance. Thank you for your understanding and support.
