sure is connection problem but i have xiaomi redmi 9 pro and the fly app do not run.

Maybe you need to be a bit more specific abut what your problem is.  From your first post, it would sound like a loss of link from the controller to the aircraft.  And I don't really know what you mean about a blinding green light (unless you really meant blinking green light).
In your second post, you say that the DJI Fly app is not working on your phone.  very different problem.

Hello there djkats. I am sorry for the trouble this has caused and thank you for reaching out. Kindly please try using a different recommended mobile device for us to isolate the said issue? Upon checking the said mobile device ( Xiaomi Redmi 9 Pro ) that your are trying to use on your DJI Mavic Mini and with the DJI Fly application. I am sorry to say that the said mobile device is not recommended for the said drone and with the said application. We would suggest using a recommended mobile device for the DJI Mavic Mini and with the DJI Fly application for compatibility and reliability purposes. There is a possibility that the Xiaomi Redmi 9 Pro will be able to work on the DJI Mavic Mini and with the DJI Fly application. But however, since it's not yet optimized with the said drone and with the said application we cannot guaranteed if it will work all the time and if it will be able to run all the functions of the DJI Fly application while using it on the DJI Mavic Mini. For reference I will post a link where in you can check the recommended mobile devices for the DJI Fly application ( https://www.dji.com/downloads/djiapp/dji-fly ). Thank you.
