I have Prestigio Multipad PMP7070.
I have deleted video files but thumbnails of them still remain in folders Last played, Recently Added and others in Video application. They are obviously cached somewhere.
How to remove them permanently?
Simple deletion will not completely erase data from iPhone, it still remain on your iPhone's internal memory and easily be recovered. You need to reset to factory. You can also try mobiledic iPhone data recovery to scan your phone and recover deleted photos from iPhone without backup
. Maybe it works!
