Newbie here. My Phantom 3 Advanced arrives on Monday. To prep I've been reading the manual, watching tons of videos, etc. Initially I plan to use the DJI Go App on my iPhone 5S to activate my P3A and to initially fly P3A. After I save up some cash (since I just dropped a lot on my P3A bundle) I eventually play to buy an inexpensive tablet so I can have a large screen, etc. Thhe question I have is, can after the initial activation on my iPhone 5S can I then switch to different devices to fly my P3A? If yes, do I need to transfer any configs, settings, etc? In addition, knowing that using to run the DJI Go App will quickly drine the battery on my iPhone 5S I'd like to have a secondary device (ex. iPad mini 3 / small table) on standby. Also, I may be upgrading to a new iPhone soon and want to know what happens when I switch phones.P Any help will be appreciated.
