I'm a member of the Norwich Astronomical Society, and our site is adjecent to Seething Airfield, which is not a busy airfield in the evenings, but an airfield in a "restricted" area on the DJI Go 4 App.

Nevertheless, we needed photos of the site and I'd spoken with the airfield earlier to check that they had nothing flying, and so was able to "unlock" the restrictions imposed by the app...
Thanks to the advice on here showing the "hard to see" blue circles that you need to tick to accept responsibility for the fligh, having inputted a code that DJI sends by text to veryify you, I was able to fly.

On an iPhone 5SE, their is not much screenspace, but I was able to make 3 flights in total to get some images and a small movie. The white dome is as you can see very dirty on one side and we will be cleaning that this Spring!

Nice shot!      

Good shooting. The sky is beautiful!
