Back to Samsung to ask them what happened. I know we only lose what we don't backup so hitting the delete before we got our files/pictures out may mean they did go away.
But let's say they are missing. Well the ugly truth is this is no PC. We can't trust these little machines.
I have a Samsung Galaxy Prevail 2 I purchased 2 weeks ago. Photos from my old phone were transferred over to this phone at the store where I purchased the phone.
Went on vacation and took pictures and one video. Got a message that no memory was available and to delete some items. Deleted a few pics and when they wasn't enough I deleted the video. Well, along with deleting the video, all my new pictures went with it, about 50 or so.
Attached the phone to my Mac, downloaded Kies, and found old photos but not missing ones. Took one pic today and that showed up in the Kies library.
Any idea what to try next? Also called Boost Mobile and that was no help.
