So I clicked on Gallery icon on phone, & it was showing none of my pictures or videos either. I tried turning my phone off, then back on, norhing, still showing norhing in Sound or Gallery. They are in My Files, but when I tried moving them, it showed they were being moved back, but when go back to Sound or Gallery, norhing there. Also tried downloading a song to see what would happen, & showed downloading, but when clicked on Sound, nothing there either. I am in tears. It has been such a hard week, my Dad just died. So, now this, there were pictures of my Dad & songs in my music that was my Dad singing. And I don t really know much about my phone. Could anyone pls pks help me? Tell me how to get pictures & songs to show back up where they were? Thank you in advance. Pls help me, am truly devastated right now.
