I sent in an email to support@dji.com three days ago requesting for a replacement because of a battery door issue for the dji mobile, and i have yet to hear a response. Can you help me with this because I am afraid some time limit for replacement will pass since this is recently bought (under a week since delivery). Dji Thor mentioned it was defective and that I should send it to replace. (source: http://forum.dji.com/thread-62564-1-1.html on #32 post)
