Ok when I first got the phone I changed my wall paper to a picture I had taken, I got sick of that pic so I just made it one of the defualt wallpapers that come on the phone. Well I found a new pic I want to make my wallpaper so I go to albums find the picture hit set as home wallpaper and change it, but when it says it was set as my wallpaper I go to look and its still the default one i set awhile ago. Why is this happening or what am I doing wrong?
