[AC Question]

I tried to change my wallpaper in mobile, but it didn't change. Through file browser only i can able to change. But previously i did though Gallery. Now it is not happening. Please help me to solve this. And one more thing by setting menu also I cant able to change.

Welcome to the forums. What device do you have? Try this. Long press on your home screen, tap on wallpapers and see if you can change it from there.
