As soon as I turned my Samsung tablet on for the first time, all of my Facebook images appeared in the gallery but I had not downloaded them on purpose. They do not appear in the file manager nor in another one I downloaded. I can't move, delete or do anything with them. Someone alerted me to the idea of 'syncing' the gallery with Facebook (I'm not 100% sure what this means). So I found the settings and turned them off. Next I was advised to try going go the application manager and clearing data. I did this and pressed "delete cache" too. The images just all came straight back and now I have no idea what to do. Please can anyone advise? Thank you, I'm completely stumped.
