My Android is running V11 of the OS and DJI Fly app V 1.5.4
From what I can find most photos are located on internal storage at Android/data/dji.go.v5/files/DCIM/OriginalFiles/Photo and DCIM/ltm
Flight logs are at Android/data/dji.go.v5/files/FlightRecord
I am using a free app called File Manager + because the default Files App which comes with Android doesn’t allow access to the above folders.
As far as editing goes I hate trying to use a mobile device. I usually use the DJI Fly app “Album” option to transfer videos and photos to my phone local storage, then transfer to my desktop computer to edit.
