I bought a Nikon D7200 camera because of the ability to live view and control the camera via app.... I need the app because unlike competitive products with folding screens this device doesnt have that.... So at the very least Id like to be able to focus/start and stop recording... This doesnt have that option... And it also doesnt allow you to change any settings at all... Its basically a file transfer app... I have no idea why this app doesnt support start and stop recording for video...
