What does this mean? S4 problem

[ajstewart213]

All of a sudden any video I take saves with a circled N symbol like in that screenshot (top left video). Anything that has that symbol on it I can't use nfc, bluetooth or s beam to send to my fiancé s5.

Now he can send me the videos via nfc etc... Hut when I play it, it instead of the video says audio only and has a corrupted file picture...

Doesn't make sense why it do this all of a sudden when the day before everything was fine.
:banghead: So please help if you can!

That's the video in my gallery sent via s beam to my s4

And this is what happens when I try to play the video.
