Drone has a major problem staying connected...

Hi there, my wife bought this Drone for me at Christmas and while I love the look, the hovering, the Back Home Return button, but my drone simply does not stay connected with the app. I have tried an Android and an iPhone. I did not purchase a drone to just fly. I got one for amazing pictures and video but so far have been very unlucky and even bad with connectivity. If anybody else has this same problem and knows what to do please advise. I do not want to try and return this thing but I may have to if the connectivity does not work.
