I have a relatively new Phantom 3 professional. When I charge my controller All 4 lights will light up White. As I'm using my drone the lights do not match up with the power range the same as my go app. Right now looking at my controller I have three white lights and the fourth white light is blinking. My Go app says 76%. Has anybody have a suggestion it seems that my Go app is correct but my controller is not. When the app gets down to critical stages my controller will shut off with at least two lights on. Thanks
