I went to a concert today andi took a video of every single song and it said not enough memory and it wouldnt even let me access my gallery, I HAD to delete stuff so I looked but It confused me so I clicked delete on what I wanted but it completely wiped every single photo/video I had ever taken on the device so now I only have a coupleof videos of the end of theconcert. Is there any way I can get my pictures and videos back ??
