After updating to 3.16 version, all I get was bad flights with loss of control and one 300ft spinning crash. All efforts to get anyone at DJI to respond to the problems of 3.16 went unanswered. Which has left me with just one option, I returned shipped my phantom today for a full refund. If DJI cannot release working flyable updates, then who needs them? I'll take my refund and spend it somewhere else! With no support why continue this sick game? No answers for the cause of fly-aways or total control loss during flight. 4.0 is just more of the same crap! I am out of here DJI you lost my trust and now my money too!
