Hello there. I am soory to know that you are having these issue with the mobile device ( Samsung Galaxy s9 plus ) that you are using to fly your DJI Mavic Mini and thank you for reaching out. Can you please try to uninstall and reinstall the DJI Fly application on the said mobile device to see if the issue will still persist? Kindly please keep us posted on the said issue for further assistance. Thank you.

I am using an S9+ and in the past I've had problems. The app was wrongly announcing RC not connected to AC while it was actually the MD not connected to RC. Anyway... it was probably ans USB connection problem, most probably specifically tied to the USB C side of the OTG cable. Unfortunately I later found out that every DJI cable that came with my Mini has some kind of out of spec tolerance and do not make good connection. Menawhile I have no problems with my own high quality charging cable or the replacement OTG they sent me.
