A:Answer The DX-4 by Sharper Image was originally released in 2017. The app that it uses is called "360 Flight" by the developer Luo Qifeng, which is no longer on the Google Play store (or at least not by that name). There are a handful of 360 Flight named apps still on the Google Play store by different developers, but seeing as how the drone was released years ago, they are no longer being updated and therefore most will just immediately crash when trying to open them or not open at all. The only one I was able to open was named "360 Mach Flight" but it wouldn't connect to the drone. The following website is the one for the DX series of drones and has an FAQ section: https://dxdronecenter.com/ The drone itself will still fly using the provided controller, but you won't be able to stream video or take photos with the camera until there is a way to connect to the drone.
