I have a Huawei P20 which I use to fly my Mavic Mini, i have a lot of disconnection problems;

At least at every 30 seconds, i lost the connection with the drone flying saying Not connected


I want to resolve this problem

Hi Silome, Huawei P20 is the compatibility device of Mavic Mini/DJI Fly. Please try to replug the connection cable, or change a different cable for the connection to see if it is related to the cable.
Besides, please make sure that the DJI Fly app has been updated to the latest version, try to reinstall the latest app as well (please back up the needed videos/pictures and make sure the flight records have been uploaded to the cloud first). And try to switch the phone to airplane mode. See if these help.
