I just purchased a DJI 3 Standard last weekend. When viewing the SD card it had a photo on it from 2014. The photos was taken with the DJI plastic cover one the lens. Is this from testing? Should I be worried? I spoke with DJI and they said they are not for sure. Just wanted to see if this has happened to anyone else and to make sure this wasnt a returned item repackaged as new. Thanks.
