My X started taking dark pictures all of a sudden and I don’t know what’s up. It used to be that if I used the slider to manually brighten the picture, the photo looked exactly like it does on screen when I snap the pic. But now, it looks bright and beautiful on screen and the picture itself looks dark. But if I move the slider up so much that the screen almost looks blown out, the picture itself looks brighter and Norma. Does anyone know what’s up? It wasn’t doing this before
