i was trying to set a picture as a wallpaper for my andriod Z990, and when i would select the picture it would get larger like its supposed to but would quickly switch to a different picture. I have tried other pictures and its not just the one photo. I have tried different ways of doing it and every way i try it does the same thing. I am really frustrated, i have a sd card if that makes a difference. Someone please help. I have tried sending photos too and it does the same thing i'll select the photo i want and another shows up in the message, this phone is about 2 months old.
