So I do not remove all the images or video from my card in the Spark after every flight so when I connect my phone the thing downloads all the images on the drone card to my phone in a super low resolution. I do not want it to sync anything to the gallery. How can I disable this feature?

Under the settings on the phone, go the the GO4 app and turn off
access to photos. If your using IOS it says read and write click there
and turn off. Android should be similar.
