And yet, despite the above shortcomings, the Mavic is an awesome quadcopter! You can list the pros and cons for a long time, but in short, this quadcopter is simply CONVENIENT. That is, you can take it in a small bag, quickly get it out of there and prepare it for take-off without straining, and after the flight you can just as quickly and effortlessly remove everything. I strongly recommend that you immediately buy attachments for antenna-legs that allow you to raise the Mavic so that it does not vacuum the take-off and landing area, as well as a plastic cap-protection for suspension. I do not recommend flying with the transparent cap that comes with the kit, since it not only spoils the picture for the camera, but it almost completely blocks the access of air to the air intake. And I recommend extremely careful use of automatic pursuit modes and others - this is a sure way to lose the quadcopter. As for phones, I don’t know why many had problems, I managed to connect both the iPhone 5S and Xiaomi Redmi 3 without any problems, the DJI GO 4 application, which is on the first, which works flawlessly on the second. The installation proceeded according to the scenario "installed the application - connected the phone to the remote control - saw the image from the quadrocopter".
