I found a solution!
My lens cover is off. No damage to the camera! Get some Velcro Tape and use the half that is grippy. Cut enough length to wrap around the lens. Trim to about 3/8th inch wide. Put sticky side around lens and turn. Cover should come free--remove Velcro. There may or may not be sticky residue. Use alcohol to remove residue. Do not over tighten cover when replacing.
PS I stayed on hold for 30 minutes with DJI. Customer support said it was hard to get the cover off and they had no remedy. I asked if I should send the Phantom back and they said no because there was nothing wrong with it. When I expressed my exasperation that they had no solution other than"sorry...it's hard to get the cover off" the customer service person hung up. I think DJI makes great products, their customer support and professionalism sucks!
