Hello and good day. Welcome to DJI Forum and thank you for the inquiry. I will be posting and official DJI Tutorial Video on how to use the DJI Spark's QuickShot Dronie Mode. Please try to follow the video and see if the issue will still persist. Please let us know on the latest progress for us to help you further. Thank you.
This was an issue with earlier versions of the DJI GO 4 app and certain mobile devices. I have an iPhone 6S and had the issue when I first got the Spark...it was resolved with new versions of the app. I recommend you make sure you have all the most current updates.
