I currently have the DJI Mavic Mini, and I own a Nokia 7.2 phone. I have tried many times to run the DJI Fly app to fly for the first time my new Mavic Mini. I even went as far as contacting DJI support who explained that this particular one may be an out of box failure. So they had me send it back and then a new Mavic Mini was sent out to me. I tried to connect the replacement Mavic Mini to my Nokia 7.2 phone and I received the same error message that said the drone was not connected to the controller. Disappointed and frustrated I decided to use my wife's Apple iPhone 8. I plugged it in and right away a connection.
I would prefer DJI to be honest and say to use this device, please use an Apple device, NOT an Android device.

I am currently using a Android version 10; Android Security Patch Level: June 5, 2020
