Ok so the gallery consists of camera, download, messaging, and various other albums that carried over from other phones and what not. Now when I open gallery I wish I could change the cover picture because some of the albums contain photos that I would not like for just anybody to see. Ive tried selecting the album but no option as to change cover. Ive also tried selecting a picture to set as... but no option for cover picture is there. Please help me change and conceal some of the photos.
