Hello,I bought DJI Mavic mini in May2020, and after appr 66 flying hours, there is a warning, "Remote control unit can't be connected to mobile device". I'm using Huawei P9 Pro and tested with newer Huawei P20 Pro, same warning. This problem started during flight, when taking a few pictures and then suddenly no connection anymore. I landed, and shut everything, restarted phone, RC and drone, repeated this several times in different order. I can't update firmware between drone and RC. I also removed and re-istalled DJI Fly app. I also bought a new USB Mini/USB C cable, but problem continues.
I contacted official repair shop here in Spain and was asked to send remote controller unit and Mini with out propellers to them.


They received items on 25th August and at same day told me via email that remote controller need to be send to DJI Netherlands for warranty repair. And it will take appr one and a half month...



This week Monday, 21st September I asked them is there any progress, no answer.



Yesterday 24th Sep, I suddenly got package from local repairshop and got my drone back. It was send to me a day before with no explanations of fault or what has been done.


I tried drone and still same problems occured. I have now a brand new phone, Samsung A71 and unused USB wire. I send again an email to DJI Spain and they replied that DJI NL wrote:


'DJI (NL) send back again with this repair quote: Remark: No fault found. Propellers missing. Aircraft tested with our test propellers and test pass. New propellers wil be delivered. We sent back to you because was ok.'


The connection/USB port in remote control seems to be faulty, but was it ever tested, I don't know.

I want to fly and took videos with my drone but it is impossible at moment.

What will DJI suggest me to do?

Best regards,
Jari

Hi Jari, I am sorry to hear that you are experiencing issue with the drone. Could you please help to confirm if the mobile device has any reaction when it is connected to the controller? If no, if it is convenient, please try to use a compatible Android mobile device, or a compatible iOS mobile device to isolate the issue again, below's the compatibility devices list for your reference.
If after testing the compatibility device, there is still no reaction and connection is still unable to established, please send the drone back again. Once you have created a new case number, please provide it to me, I will keep my close attention to it.
