Whenever I take a picture using the camera or a screenshot, it doesn't get saved. It just disappears. The music has disappeared as well and the same thing with the camera goes for the videos too. Nothing gets saved and it's like I have no files at all. Although, whenever I plug my phone in my laptop and check my music, pictures, camera pictures, and videos, everything I had was still there. It all disappeared yesterday when I plugged my phone in my laptop and took it out. What do I do to fix this?
