I'm a newcomer to DJI Phantom. I got a Phantom 3 Standard. I'm using it with my Android phone - a Samsung Galaxy 3. I noticed files appearing in the "gallery" on my phone. Two folders - "DJI_RECORD" and "CACHE_IMAGE". The first seems to contain video images but my phone doesn't have the codec to play them. The second folder contains still images. I'm guessing thumbnails and full sized. As I transfer my video and still images from the card to my PC, these files did not concern me until I borrowed a Galaxy 4 phone from a friend of mine to use with the Phantom 3 and we couldn't get the phone to charge properly afterwards using either a power pack or the charging unit from the cigar lighter in the car. This morning she contacted me to tell me that her phone's battery was dead and that after charging it while it was turned off she found new files on it and is sure that they were downloaded when she connected to WIFi. I can't verify that claim but ...... I have two basic questions: 1. Are files downloaded to our phones only from the Phantom 3 during a flight or is there any other place (cloud?)? 2. Is there a way to completely turn off this file transfer to our phones? ADVthanksANCE paul Timon.
