Okay, this dosen't seem normal. I had a picture on my lockscreen and the picture was in my downloads folder. And then I downloaded AVG and not realizing what I have done I said it was okay for it to delete my downloads folder. So then I did a clean up. and it deleted all of my pictures on the folder. Well now my phone will not let me change my lockscreen picture. And then for another dumb reason I accidentally changed the app/software to change it to google+. I can't change my background and I really want to. My phone is an ATT Android Avail One. HOW DO I FIX THIS?:-\:'(
