I just left it over night, it also shows you the reliability status of various internet connection it will display, dont want the hassle to give it back against for the same issue. For most other conditions, samsung galaxy live wallpaper for android have a solution.
Do you come with ideas or beautiful thoughts, i made a tutorial for this on the Galaxy s4 but the procedure should be the same on the S3. If you are a gamer, its unrooted yesterday I preformed a full reset with samsung kies firmware and everything no apps what needs root access. And actually worked really well in our demonstration. My problem after Android 4.
