So, my wife's phone (Galaxy Note 2) was running out of memory. She decided to move all of her video files into one folder to be prepared for migration to our NAS. When she finished consolidating the files, everything looked fine, but she didn't play any of the videos. She then noticed that some of the videos went black in the gallery. She tried opening them and they failed to run. I tried running those videos on Win7 with VLC, on Mac (which tried to convert them and failed), I tried recovering them with http://grauonline.de/ application and only got the sound back. Out of 51 videos that she moved, about 30 were corrupted. I am guessing that because she only had approximately ~5-6MB of storage space left on her phone, during the movement, there wasn't enough for cache or whatever (I have very limited experience with Android development, so I'm not sure how it works on that OS), and the files became corrupted.
Has anyone experienced anything similar? Everything I've read had to do with bad SD cards, corruption during recording, etc. But I couldn't find anything that was similar to our situation. I also couldn't find any solutions to fix it. Does anyone have any ideas? Those videos are priceless to us, because they're of our daughter.... so recovering them is my highest priority.
I should mention that HEX data doesn't look bad, as in... I see no zeroes. Therefore, data should be recoverable? I was able to get the sound back, but no video.
Here's entropy report for one of the videos:
[NOTICE] entropy 0 - 21147 -- 0.997836

0.6 or higher means it contains video data. I tried every option in that program and I couldn't repair. I can't find another one that people say works.
